feat: issue_close + issue_reopen tools (#30)

Adds two MCP tools that PATCH /api/v1/repos/{owner}/{name}/issues/{number}
with {"state":"closed"} or {"state":"open"}. Both use a shared
SetIssueState helper on the gitea client.

- internal/gitea/issues.go: SetIssueState method using the existing
  PatchJSON + MapStatus + json.Unmarshal pattern from GetIssue.
- internal/tools/issue_close.go: IssueClose tool. owner+name+number
  args. Owner allowlist enforced. Returns the updated issue. Reversible
  via issue_reopen, classified LOW risk.
- internal/tools/issue_reopen.go: mirror of IssueClose with
  state="open". Same risk profile.
- Registered both tools in cmd/gitea-mcp/main.go.
- Tests for both: success (asserts PATCH method, path, body), 404,
  and allowlist rejection — same shape as issue_get_test.go.

Closes #30

+# Agent context — Mathias workspace
+
+<!-- Canonical root context for all AI coding agents.
+     Lives at: ~/dev/.context/AGENT.md
+     Applies to every project under ~/dev/ unless overridden.
+     
+     Run `task context:sync` from ~/dev/ to regenerate harness-specific files.
+     Project-level context in .context/PROJECT.md layers on top of this. -->
+
+## Who I am
+
+I'm Mathias, a digital product manager and technology consultant based in Sweden.
+I build software, research emerging tech, and deliver consulting engagements
+for clients under NDA. I work across AI/ML, financial automation, web applications,
+and climate/sustainability tech.
+
+## How I work with agents
+
+- I think like a product manager — I care about *why* before *how*
+- I want agents to be opinionated and push back, not just execute blindly
+- I prefer concise responses; skip ceremony and get to the point
+- When I say "build this", I mean production-quality with tests, not a demo
+- Ask me before making irreversible changes or adding heavy dependencies
+- I work with confidential client data — never send it to cloud APIs unless I explicitly say it's OK
+
+## Behavior rules
+
+These rules apply to every task across every project, regardless of harness.
+
+1. **No assumptions.** Don't hide confusion — surface it. Surface tradeoffs explicitly.
+   Think before coding; if the problem is unclear, ask or state assumptions before acting.
+2. **Minimum viable code.** Solve with the smallest change that works. Nothing
+   speculative, no "while we're here" cleanups, no premature abstractions. Simplicity first.
+3. **Surgical changes.** Touch only what the task requires. Leave unrelated code,
+   files, and formatting alone. Diffs should be small and reviewable.
+4. **Goal-driven execution.** Define clear success criteria up front for every task.
+   Loop — implement, verify, refine — until those criteria are met. Don't claim
+   completion without evidence (tests pass, command output, observed behavior).
+5. **Trunk-Based Development — commit directly to main.** Every commit is one
+   logical change (one tool, one fix, one test) with passing tests. Main is always
+   deployable. Never create long-lived feature branches.
+
+   **Exception — parallel agents on same repo:** If another agent is known to be
+   actively working on the same repo simultaneously, create a short-lived branch
+   (`agent/<description>`), finish the task, and merge to main within the same
+   session. Do not leave agent branches open between sessions.
+
+   **Exception — external contributor or client four-eyes requirement:** Use
+   PR flow only when a human reviewer outside the project is required. Document
+   the reason in PROJECT.md.
+
+## Default stack
+
+| Layer | Default | Fallback | Last resort |
+|-------|---------|----------|-------------|
+| Language | Go | Python | TypeScript, Java, C |
+| UI | HTMX + Templ | Server-rendered HTML | React (only if SPA is justified) |

+| Agents (Go) | google.golang.org/adk + pkg/litellm adapter | — | — |
+
+Exploratory: Rust, Zig — I'll tell you when I want these.
+
+## Code conventions
+
+- **Go style**: golines, gofumpt, golangci-lint
+- **Errors**: `fmt.Errorf("operation: %w", err)` — never naked, never log-and-return
+- **Naming**: stdlib conventions, no stuttering
+- **Architecture**: prefer stdlib over frameworks, constructor injection, env-var config parsed into typed structs
+- **Git**: conventional commits (`feat:`, `fix:`, `chore:`), commit directly to main,
+  one logical change per commit, CI is the quality gate
+- **Never**: long-lived feature branches, PRs for solo work, direct push without
+  passing `task check` locally first
+- **Security**: no secrets in code, govulncheck before adding deps, SOPS for encrypted config
+- **Dependencies**: prefer stdlib. testify, slog, templ, sqlc, google.golang.org/adk (agent projects only) are pre-approved; anything else needs justification in the commit message
+
+## Infrastructure
+
+Three machines on Tailscale:
+
+| Machine | Role | Key specs |
+|---------|------|-----------|
+| koala | GPU inference, heavy compute | RTX 5070, runs k3s + llama-swap + shared postgres18/pgvector |
+| iguana | Services, builds | M2 Ultra Mac |
+| flamingo | Daily driver, edge | Mac mini, ~/dev is here |
+
+- **Model routing**: LiteLLM in front of llama-swap (local) + cloud APIs (when permitted)
+- **Orchestration**: k3s cluster across all three machines
+- **Networking**: Tailscale mesh
+
+## Project landscape
+
+All development repos live at `~/dev/` (softlink from `~/Documents/local-dev/`).
+
+Organized in thematic folders:
+
+| Folder | Focus | Count |
+|--------|-------|-------|
+| `GO/` | Go web frameworks, API integrations, learning projects | ~10 |
+| `AI/` | ML research, AI frameworks (FinRL, DSPy, crawl4ai) | ~6 |
+| `AGENTS/` | Autonomous agents, coding agents, MCP servers, infra | ~15 |
+| `QKX/` | Invoice processing, financial automation, payment systems | ~13 |
+| `XT/` | Climate data, sustainability (Klimatkollen, Garbo) | ~2 |
+
+See `~/dev/PROJECT_SUMMARY.md` for detailed descriptions of each project.
+
+### Key active projects
+
+- **super-koala** (`AGENTS/`) — multi-component agent stack with LangGraph, DSPy, MCP
+- **azure-tiger** (`QKX/`) — invoice extraction → ISO 20022 payment instructions
+- **gocrwl** (`AGENTS/`) — Go web crawler with containerized deployment
+- **koala-ai-stack** (`AGENTS/`) — local AI server infrastructure management
+- **klimatkollen** (`XT/`) — Swedish municipal climate data platform
+
+## Knowledge base — actively use it
+
+A persistent brain (BM25 search + LLM-synthesised Q&A) survives across sessions,
+hosts, and harnesses. It holds 100+ hard-won entries: infra incident postmortems,
+Go pitfalls, framework gotchas, design principles, ADRs. **It is not optional
+reference material — query it actively, not just when explicitly told.**
+
+### When to query (treat as a reflex)
+
+- **Before** starting a non-trivial task — search for prior art with the symptom
+  AND the system component ("how did we solve X in Y?"). 5 seconds beats 5 hours.
+- **When debugging** — search for the error string, the stack frame, the affected
+  service. Past you may have already paid this tax.
+- **Before adopting** a pattern, library, framework, or model name — check if it
+  was tried and rejected, or what the integration footguns are.
+- **When making architectural decisions** — search for the domain + "ADR" or
+  "decision" to find prior reasoning before re-deriving it.
+- **When a recommendation feels novel** — challenge yourself: "has this been
+  documented?" The brain often has it.
+
+### When to write
+
+After you discover something that **future-you would forget** and that **isn't
+recoverable from the code, git log, or PR description alone**:
+
+- Bugs whose root cause is non-obvious and generalisable beyond this project.
+- Framework / library / model-name quirks that bit you and would bite anyone.
+- Design principles validated under fire (e.g. "every `_get` needs a `_list`").
+- Postmortems for incidents: what broke, why, how diagnosed, what to do next time.
+
+DON'T write project status, sprint progress, PR summaries, or "what I did this
+session" — those rot fast and the originals are in git/gitea anyway. Brain
+entries that age well are about *why*, *how to avoid*, and *what to do when*.
+
+### How to access (per harness)
+
+| Harness | Query | Write |
+|---------|-------|-------|
+| **Claude Code, Claude Desktop** | `brain_query` (BM25), `brain_answer` (LLM-synth + sources) MCP tools | `brain_write` MCP tool |
+| **Crush, Pi, Antigravity, other MCP-capable** | same MCP server: `ingestion-brain` (via the `mcp__*_brain__*` namespace once authenticated) | same |
+| **Anything HTTP-only (curl, scripts)** | `POST https://brain-mcp.d-ma.be/query` with `{"query":"..."}` (auth via `BRAIN_MCP_TOKEN`) | `POST .../write` with `{"content":"...","filename":"..."}` |
+| **Browser / human inspection** | `https://gitea.d-ma.be/mathias/hyperguild` → `knowledge/` and `wiki/` markdown files |
+
+- **Scoping**: defaults to `public` collection; client projects filter to `{client}` + `public`.
+- **Routing**: brain_answer's LLM uses berget.ai as primary, iguana ollama as
+  fallback. Both are configurable in the `supervisor/ingestion-deployment.yaml`
+  on the koala k3s cluster; don't hardcode local-only model names into the
+  berget URL (see knowledge entry on namespace mismatches).
+
+### Quick reflex checks
+
+If you find yourself about to say any of these out loud, you owe yourself a brain query first:
+
+- "I think the issue might be..."
+- "Let me try X and see..."
+- "I'll just write a script to..."
+- "This is probably a new bug..."
+- "Has anyone done this before?" — *yes, probably, go check.*
+
+## Client work rules
+
+When working on a project tagged with a client name:
+1. Never send code, data, or context to cloud APIs — use local models only
+2. Never reference other client projects or their data
+3. Keep all artifacts within the client's git org / directory
+4. Treat everything as confidential unless told otherwise
+
+## Harness-agnostic principles
+
+This context is designed to work with any AI coding tool:
+- Claude Code, Cursor, Aider, Open WebUI, Charmbracelet Mods/Crush
+- Pi Coding Agent, Mistral Vibe, Antigravity
+- Any tool that accepts a system prompt or reads a markdown context file
+
+The canonical source is always `.context/AGENT.md` (root) and `.context/PROJECT.md` (per-project).
+Derived files are committed (see *How context propagates* below) so a `git pull` on any host yields full agent context with no setup.
+
+## How context propagates
+
+Canonical sources of truth:
+- Universal: `~/dev/.context/AGENT.md` (this file)
+- Project: `<repo>/.context/PROJECT.md` (per-repo)
+
+Derived files (committed, regenerated by `task context:sync`):
+- `CLAUDE.md`, `AGENTS.md`, `.cursorrules`, `.aider.conventions.md`,
+  `.context/system-prompt.txt`
+
+Workflow:
+1. Edit a canonical file. Run `task context:sync`. Commit canonical and
+   derived together. Push.
+2. On any other host, `git pull` brings both. Claude Code (tree-walking)
+   uses `CLAUDE.md`; Crush / Pi / Antigravity (cwd-only) use `AGENTS.md`;
+   Cursor uses `.cursorrules`; Aider uses `.aider.conventions.md`.
+3. `task check` runs `context:sync` then asserts `git status --porcelain`
+   is empty over the derived files (catches both modified-tracked drift
+   and missing-untracked adapters). A drift fails the check with a
+   message telling you to stage the regenerated files.
+
+Behavior rules in this file and per-project rules in `PROJECT.md` apply
+unconditionally on every host, every harness.
+
+## Engineering Skills
+
+Shared engineering skills are available in `~/dev/.skills/`. Load on demand via the index.
+
+See `~/dev/.skills/SKILLS_INDEX.md` for the full list with descriptions and "use when" triggers.
+
+Key skills:
+- **TDD**: always write tests first — load `tdd` skill
+- **Code Review**: load `code-review` skill before any review
+- **SOLID/Clean Code**: load `solid` or `clean-code` skill for design work
+- **Problem first**: load `problem-analysis` skill before coding non-trivial features

+## Conventions
+
+### Code style
+- Go: follow `golines`, `gofumpt`, `golangci-lint` with project config

+- Structured logging via `slog`
+
+### Git
+- Conventional commits: `feat:`, `fix:`, `chore:`, `docs:`, `refactor:`
+- **Trunk-Based Development:** commit directly to main. One logical change per commit.

+- No feature branches, no PRs for solo/agent work.
+- Exception: if a parallel agent session is active on this repo, use a short-lived

+
+### Security
+- No secrets in code, ever — use env vars or SOPS-encrypted files
+- Client data never leaves local network unless explicitly cleared
+- Dependencies: audit with `govulncheck` before adding

+## Knowledge base access
+
+This project can query the shared knowledge base via MCP or HTTP:
+
+- **MCP endpoint**: `mcp://localhost:3100/knowledge`

+## Agent instructions
+
+When acting as a coding agent on this project:

+- **Naming**: stdlib conventions, no stuttering
+- **Architecture**: prefer stdlib over frameworks, constructor injection, env-var config parsed into typed structs
+- **Git**: conventional commits (`feat:`, `fix:`, `chore:`), commit directly to main,
+  one logical change per commit, CI is the quality gate
+- **Never**: long-lived feature branches, PRs for solo work, direct push without
+  passing `task check` locally first
+- **Security**: no secrets in code, govulncheck before adding deps, SOPS for encrypted config
+- **Dependencies**: prefer stdlib. testify, slog, templ, sqlc, google.golang.org/adk (agent projects only) are pre-approved; anything else needs justification in the commit message
+
+## Infrastructure
+
+Three machines on Tailscale:
+
+| Machine | Role | Key specs |
+|---------|------|-----------|
+| koala | GPU inference, heavy compute | RTX 5070, runs k3s + llama-swap + shared postgres18/pgvector |
+| iguana | Services, builds | M2 Ultra Mac |
+| flamingo | Daily driver, edge | Mac mini, ~/dev is here |
+
+- **Model routing**: LiteLLM in front of llama-swap (local) + cloud APIs (when permitted)
+- **Orchestration**: k3s cluster across all three machines
+- **Networking**: Tailscale mesh
+
+## Project landscape
+
+All development repos live at `~/dev/` (softlink from `~/Documents/local-dev/`).
+
+Organized in thematic folders:
+
+| Folder | Focus | Count |
+|--------|-------|-------|
+| `GO/` | Go web frameworks, API integrations, learning projects | ~10 |
+| `AI/` | ML research, AI frameworks (FinRL, DSPy, crawl4ai) | ~6 |
+| `AGENTS/` | Autonomous agents, coding agents, MCP servers, infra | ~15 |
+| `QKX/` | Invoice processing, financial automation, payment systems | ~13 |
+| `XT/` | Climate data, sustainability (Klimatkollen, Garbo) | ~2 |
+
+See `~/dev/PROJECT_SUMMARY.md` for detailed descriptions of each project.
+
+### Key active projects
+
+- **super-koala** (`AGENTS/`) — multi-component agent stack with LangGraph, DSPy, MCP
+- **azure-tiger** (`QKX/`) — invoice extraction → ISO 20022 payment instructions
+- **gocrwl** (`AGENTS/`) — Go web crawler with containerized deployment
+- **koala-ai-stack** (`AGENTS/`) — local AI server infrastructure management
+- **klimatkollen** (`XT/`) — Swedish municipal climate data platform
+
+## Knowledge base — actively use it
+
+A persistent brain (BM25 search + LLM-synthesised Q&A) survives across sessions,
+hosts, and harnesses. It holds 100+ hard-won entries: infra incident postmortems,
+Go pitfalls, framework gotchas, design principles, ADRs. **It is not optional
+reference material — query it actively, not just when explicitly told.**
+
+### When to query (treat as a reflex)
+
+- **Before** starting a non-trivial task — search for prior art with the symptom
+  AND the system component ("how did we solve X in Y?"). 5 seconds beats 5 hours.
+- **When debugging** — search for the error string, the stack frame, the affected
+  service. Past you may have already paid this tax.
+- **Before adopting** a pattern, library, framework, or model name — check if it
+  was tried and rejected, or what the integration footguns are.
+- **When making architectural decisions** — search for the domain + "ADR" or
+  "decision" to find prior reasoning before re-deriving it.
+- **When a recommendation feels novel** — challenge yourself: "has this been
+  documented?" The brain often has it.
+
+### When to write
+
+After you discover something that **future-you would forget** and that **isn't
+recoverable from the code, git log, or PR description alone**:
+
+- Bugs whose root cause is non-obvious and generalisable beyond this project.
+- Framework / library / model-name quirks that bit you and would bite anyone.
+- Design principles validated under fire (e.g. "every `_get` needs a `_list`").
+- Postmortems for incidents: what broke, why, how diagnosed, what to do next time.
+
+DON'T write project status, sprint progress, PR summaries, or "what I did this
+session" — those rot fast and the originals are in git/gitea anyway. Brain
+entries that age well are about *why*, *how to avoid*, and *what to do when*.
+
+### How to access (per harness)
+
+| Harness | Query | Write |
+|---------|-------|-------|
+| **Claude Code, Claude Desktop** | `brain_query` (BM25), `brain_answer` (LLM-synth + sources) MCP tools | `brain_write` MCP tool |
+| **Crush, Pi, Antigravity, other MCP-capable** | same MCP server: `ingestion-brain` (via the `mcp__*_brain__*` namespace once authenticated) | same |
+| **Anything HTTP-only (curl, scripts)** | `POST https://brain-mcp.d-ma.be/query` with `{"query":"..."}` (auth via `BRAIN_MCP_TOKEN`) | `POST .../write` with `{"content":"...","filename":"..."}` |
+| **Browser / human inspection** | `https://gitea.d-ma.be/mathias/hyperguild` → `knowledge/` and `wiki/` markdown files |
+
+- **Scoping**: defaults to `public` collection; client projects filter to `{client}` + `public`.
+- **Routing**: brain_answer's LLM uses berget.ai as primary, iguana ollama as
+  fallback. Both are configurable in the `supervisor/ingestion-deployment.yaml`
+  on the koala k3s cluster; don't hardcode local-only model names into the
+  berget URL (see knowledge entry on namespace mismatches).
+
+### Quick reflex checks
+
+If you find yourself about to say any of these out loud, you owe yourself a brain query first:
+
+- "I think the issue might be..."
+- "Let me try X and see..."
+- "I'll just write a script to..."
+- "This is probably a new bug..."
+- "Has anyone done this before?" — *yes, probably, go check.*
+
+## Client work rules
+
+When working on a project tagged with a client name:
+1. Never send code, data, or context to cloud APIs — use local models only
+2. Never reference other client projects or their data
+3. Keep all artifacts within the client's git org / directory
+4. Treat everything as confidential unless told otherwise
+
+## Harness-agnostic principles
+
+This context is designed to work with any AI coding tool:
+- Claude Code, Cursor, Aider, Open WebUI, Charmbracelet Mods/Crush
+- Pi Coding Agent, Mistral Vibe, Antigravity
+- Any tool that accepts a system prompt or reads a markdown context file
+
+The canonical source is always `.context/AGENT.md` (root) and `.context/PROJECT.md` (per-project).
+Derived files are committed (see *How context propagates* below) so a `git pull` on any host yields full agent context with no setup.
+
+## How context propagates
+
+Canonical sources of truth:
+- Universal: `~/dev/.context/AGENT.md` (this file)
+- Project: `<repo>/.context/PROJECT.md` (per-repo)
+
+Derived files (committed, regenerated by `task context:sync`):
+- `CLAUDE.md`, `AGENTS.md`, `.cursorrules`, `.aider.conventions.md`,
+  `.context/system-prompt.txt`
+
+Workflow:
+1. Edit a canonical file. Run `task context:sync`. Commit canonical and
+   derived together. Push.
+2. On any other host, `git pull` brings both. Claude Code (tree-walking)
+   uses `CLAUDE.md`; Crush / Pi / Antigravity (cwd-only) use `AGENTS.md`;
+   Cursor uses `.cursorrules`; Aider uses `.aider.conventions.md`.
+3. `task check` runs `context:sync` then asserts `git status --porcelain`
+   is empty over the derived files (catches both modified-tracked drift
+   and missing-untracked adapters). A drift fails the check with a
+   message telling you to stage the regenerated files.
+
+Behavior rules in this file and per-project rules in `PROJECT.md` apply
+unconditionally on every host, every harness.
+
+## Engineering Skills
+
+Shared engineering skills are available in `~/dev/.skills/`. Load on demand via the index.
+
+See `~/dev/.skills/SKILLS_INDEX.md` for the full list with descriptions and "use when" triggers.
+
+Key skills:
+- **TDD**: always write tests first — load `tdd` skill
+- **Code Review**: load `code-review` skill before any review
+- **SOLID/Clean Code**: load `solid` or `clean-code` skill for design work
+- **Problem first**: load `problem-analysis` skill before coding non-trivial features
+
+---
+
+# Project context
+
+<!-- Canonical project context. Edit this, run `task context:sync`.
+     Root agent context from ~/dev/.context/AGENT.md is automatically
+     prepended for harnesses that don't walk the directory tree. -->

+## Identity
+
+- **Name**: gitea-mcp
+- **Owner**: Mathias
+- **Client**: personal
+- **Repo**: https://gitea.d-ma.be/mathias/gitea-mcp
+- **Status**: active
+
+## Stack
+
+- **Primary language**: Go
+- **UI layer**: HTMX + Templ (when applicable)
+- **Fallback languages**: Python, TypeScript (justify in PR if used)
+- **Build**: Task (taskfile.dev), not Make
+- **Containers**: Docker (compose for dev, k3s for deploy)
+- **Target infra**: koala (GPU workloads), iguana (services), flamingo (edge)
+
+## Conventions
+
+### Code style
+- Go: follow `golines`, `gofumpt`, `golangci-lint` with project config
+- Tests: table-driven, in `_test.go` next to source, `testify` for assertions
+- Errors: wrap with `fmt.Errorf("operation: %w", err)`, no naked returns
+- Naming: stdlib conventions, no stuttering (`http.Client` not `http.HTTPClient`)
+
+### Architecture preferences
+- Prefer standard library over frameworks (net/http over gin/echo)
+- Dependency injection via constructor functions, not containers
+- Configuration via environment variables, parsed at startup into a typed struct
+- Structured logging via `slog`
+
+### Git
+- Conventional commits: `feat:`, `fix:`, `chore:`, `docs:`, `refactor:`
+- **Trunk-Based Development:** commit directly to main. One logical change per commit.
+- Run `task check` locally before every push. CI is the quality gate, not branch protection.
+- No feature branches, no PRs for solo/agent work.
+- Exception: if a parallel agent session is active on this repo, use a short-lived
+  `agent/<description>` branch and merge within the same session.
+
+### Security
+- No secrets in code, ever — use env vars or SOPS-encrypted files
+- Client data never leaves local network unless explicitly cleared
+- Dependencies: audit with `govulncheck` before adding
+
+## Knowledge base access
+
+This project can query the shared knowledge base via MCP or HTTP:
+
+- **MCP endpoint**: `mcp://localhost:3100/knowledge`
+- **HTTP fallback**: `http://localhost:3100/api/v1/search`
+- **Scoping**: queries are filtered to collection `personal` + `public`
+
+## Behavior rules
+
+These rules apply to every task in this project, regardless of harness.
+
+1. **No assumptions.** Don't hide confusion — surface it. Surface tradeoffs explicitly.
+   Think before coding; if the problem is unclear, ask or state assumptions before acting.
+2. **Minimum viable code.** Solve with the smallest change that works. Nothing
+   speculative, no "while we're here" cleanups, no premature abstractions. Simplicity first.
+3. **Surgical changes.** Touch only what the task requires. Leave unrelated code,
+   files, and formatting alone. Diffs should be small and reviewable.
+4. **Goal-driven execution.** Define clear success criteria up front for every task.
+   Loop — implement, verify, refine — until those criteria are met. Don't claim
+   completion without evidence (tests pass, command output, observed behavior).
+
+## Agent instructions
+
+When acting as a coding agent on this project:
+
+1. Read this file and all `SKILL.md` files in `.skills/` before starting work
+2. Run `task check` before committing (lint + test + vet)
+3. If unsure about a convention, check `DECISIONS.md` or ask
+4. Never modify files outside the project root without explicit permission
+5. When adding a dependency, explain why in the commit message
+6. Commit directly to main. Run `task check` before every push. Never create
+   feature branches unless a parallel agent is simultaneously active on this repo.
+7. For client projects: never send code or context to cloud APIs — use local models via LiteLLM
+
+## Current state — v0.2.5 (2026-05-17)
+
+All v0.2 work is complete and deployed. No active sprint.
+
+### What shipped
+
+| Tag | PR | Tools / fixes |
+|-----|----|---------------|
+| v0.2.2 | #21 | repo_create, repo_update, repo_mirror_push |
+| v0.2.3 | #22 | repo_tree, repo_topics_update, file_read dir fix |
+| v0.2.4 | #23 | issue_get, release_create, repo_delete |
+| v0.2.5 | #26 | repo_update archived+template, create_project_from_template template_name, pr_files_diff loop fix |
+
+Current main: `e31fd3f`. CI green. Deployed via Flux.
+
+### Next up
+
+1. **`hyperguild new-project` v1** — primary next target.
+   See brain node `adr-new-project-gitea-first-github-mirror` for full flow spec.
+
+2. **Issue #19** — end-to-end mirror flow verification.
+   `repo_mirror_push` is implemented but the full flow (create repo → add push mirror → verify sync to GitHub) has not been tested manually. Do this before relying on it in production.

+## Who I am
+
+I'm Mathias, a digital product manager and technology consultant based in Sweden.
+I build software, research emerging tech, and deliver consulting engagements
+for clients under NDA. I work across AI/ML, financial automation, web applications,
+and climate/sustainability tech.
+
+## How I work with agents
+
+- I think like a product manager — I care about *why* before *how*
+- I want agents to be opinionated and push back, not just execute blindly
+- I prefer concise responses; skip ceremony and get to the point
+- When I say "build this", I mean production-quality with tests, not a demo
+- Ask me before making irreversible changes or adding heavy dependencies
+- I work with confidential client data — never send it to cloud APIs unless I explicitly say it's OK
+
+## Behavior rules
+
+These rules apply to every task across every project, regardless of harness.
+
+1. **No assumptions.** Don't hide confusion — surface it. Surface tradeoffs explicitly.

+   Loop — implement, verify, refine — until those criteria are met. Don't claim
+   completion without evidence (tests pass, command output, observed behavior).
+5. **Trunk-Based Development — commit directly to main.** Every commit is one
+   logical change (one tool, one fix, one test) with passing tests. Main is always
+   deployable. Never create long-lived feature branches.
+
+   **Exception — parallel agents on same repo:** If another agent is known to be
+   actively working on the same repo simultaneously, create a short-lived branch
+   (`agent/<description>`), finish the task, and merge to main within the same
+   session. Do not leave agent branches open between sessions.
+
+   **Exception — external contributor or client four-eyes requirement:** Use
+   PR flow only when a human reviewer outside the project is required. Document
+   the reason in PROJECT.md.

+- **super-koala** (`AGENTS/`) — multi-component agent stack with LangGraph, DSPy, MCP
+- **azure-tiger** (`QKX/`) — invoice extraction → ISO 20022 payment instructions
+- **gocrwl** (`AGENTS/`) — Go web crawler with containerized deployment
+- **koala-ai-stack** (`AGENTS/`) — local AI server infrastructure management
+- **klimatkollen** (`XT/`) — Swedish municipal climate data platform
+
+## Knowledge base — actively use it
+
+A persistent brain (BM25 search + LLM-synthesised Q&A) survives across sessions,
+hosts, and harnesses. It holds 100+ hard-won entries: infra incident postmortems,
+Go pitfalls, framework gotchas, design principles, ADRs. **It is not optional
+reference material — query it actively, not just when explicitly told.**
+
+### When to query (treat as a reflex)
+
+- **Before** starting a non-trivial task — search for prior art with the symptom
+  AND the system component ("how did we solve X in Y?"). 5 seconds beats 5 hours.
+- **When debugging** — search for the error string, the stack frame, the affected
+  service. Past you may have already paid this tax.
+- **Before adopting** a pattern, library, framework, or model name — check if it
+  was tried and rejected, or what the integration footguns are.
+- **When making architectural decisions** — search for the domain + "ADR" or
+  "decision" to find prior reasoning before re-deriving it.
+- **When a recommendation feels novel** — challenge yourself: "has this been
+  documented?" The brain often has it.
+
+### When to write
+
+After you discover something that **future-you would forget** and that **isn't
+recoverable from the code, git log, or PR description alone**:
+
+- Bugs whose root cause is non-obvious and generalisable beyond this project.
+- Framework / library / model-name quirks that bit you and would bite anyone.
+- Design principles validated under fire (e.g. "every `_get` needs a `_list`").
+- Postmortems for incidents: what broke, why, how diagnosed, what to do next time.
+
+DON'T write project status, sprint progress, PR summaries, or "what I did this
+session" — those rot fast and the originals are in git/gitea anyway. Brain
+entries that age well are about *why*, *how to avoid*, and *what to do when*.
+
+### How to access (per harness)
+
+| Harness | Query | Write |
+|---------|-------|-------|
+| **Claude Code, Claude Desktop** | `brain_query` (BM25), `brain_answer` (LLM-synth + sources) MCP tools | `brain_write` MCP tool |
+| **Crush, Pi, Antigravity, other MCP-capable** | same MCP server: `ingestion-brain` (via the `mcp__*_brain__*` namespace once authenticated) | same |
+| **Anything HTTP-only (curl, scripts)** | `POST https://brain-mcp.d-ma.be/query` with `{"query":"..."}` (auth via `BRAIN_MCP_TOKEN`) | `POST .../write` with `{"content":"...","filename":"..."}` |
+| **Browser / human inspection** | `https://gitea.d-ma.be/mathias/hyperguild` → `knowledge/` and `wiki/` markdown files |
+
+- **Scoping**: defaults to `public` collection; client projects filter to `{client}` + `public`.
+- **Routing**: brain_answer's LLM uses berget.ai as primary, iguana ollama as
+  fallback. Both are configurable in the `supervisor/ingestion-deployment.yaml`
+  on the koala k3s cluster; don't hardcode local-only model names into the
+  berget URL (see knowledge entry on namespace mismatches).
+
+### Quick reflex checks
+
+If you find yourself about to say any of these out loud, you owe yourself a brain query first:
+
+- "I think the issue might be..."
+- "Let me try X and see..."
+- "I'll just write a script to..."
+- "This is probably a new bug..."
+- "Has anyone done this before?" — *yes, probably, go check.*
+
+## Client work rules
+
+When working on a project tagged with a client name:
+1. Never send code, data, or context to cloud APIs — use local models only
+2. Never reference other client projects or their data
+3. Keep all artifacts within the client's git org / directory
+4. Treat everything as confidential unless told otherwise
+
+## Harness-agnostic principles
+
+This context is designed to work with any AI coding tool:
+- Claude Code, Cursor, Aider, Open WebUI, Charmbracelet Mods/Crush
+- Pi Coding Agent, Mistral Vibe, Antigravity
+- Any tool that accepts a system prompt or reads a markdown context file
+
+The canonical source is always `.context/AGENT.md` (root) and `.context/PROJECT.md` (per-project).
+Derived files are committed (see *How context propagates* below) so a `git pull` on any host yields full agent context with no setup.
+
+## How context propagates
+
+Canonical sources of truth:
+- Universal: `~/dev/.context/AGENT.md` (this file)
+- Project: `<repo>/.context/PROJECT.md` (per-repo)
+
+Derived files (committed, regenerated by `task context:sync`):
+- `CLAUDE.md`, `AGENTS.md`, `.cursorrules`, `.aider.conventions.md`,
+  `.context/system-prompt.txt`
+
+Workflow:
+1. Edit a canonical file. Run `task context:sync`. Commit canonical and
+   derived together. Push.
+2. On any other host, `git pull` brings both. Claude Code (tree-walking)
+   uses `CLAUDE.md`; Crush / Pi / Antigravity (cwd-only) use `AGENTS.md`;
+   Cursor uses `.cursorrules`; Aider uses `.aider.conventions.md`.
+3. `task check` runs `context:sync` then asserts `git status --porcelain`
+   is empty over the derived files (catches both modified-tracked drift
+   and missing-untracked adapters). A drift fails the check with a
+   message telling you to stage the regenerated files.
+
+Behavior rules in this file and per-project rules in `PROJECT.md` apply
+unconditionally on every host, every harness.

+These rules apply to every task in this project, regardless of harness.
+
+1. **No assumptions.** Don't hide confusion — surface it. Surface tradeoffs explicitly.
+   Think before coding; if the problem is unclear, ask or state assumptions before acting.
+2. **Minimum viable code.** Solve with the smallest change that works. Nothing
+   speculative, no "while we're here" cleanups, no premature abstractions. Simplicity first.
+3. **Surgical changes.** Touch only what the task requires. Leave unrelated code,
+   files, and formatting alone. Diffs should be small and reviewable.
+4. **Goal-driven execution.** Define clear success criteria up front for every task.
+   Loop — implement, verify, refine — until those criteria are met. Don't claim
+   completion without evidence (tests pass, command output, observed behavior).
+
+## Agent instructions
+
+When acting as a coding agent on this project:
+
+1. Read this file and all `SKILL.md` files in `.skills/` before starting work
+2. Run `task check` before committing (lint + test + vet)
+3. If unsure about a convention, check `DECISIONS.md` or ask
+4. Never modify files outside the project root without explicit permission
+5. When adding a dependency, explain why in the commit message
+6. Commit directly to main. Run `task check` before every push. Never create
+   feature branches unless a parallel agent is simultaneously active on this repo.
+7. For client projects: never send code or context to cloud APIs — use local models via LiteLLM
+
+## Current state — v0.2.5 (2026-05-17)
+
+All v0.2 work is complete and deployed. No active sprint.

+
+# Go project patterns
+
+## New endpoint checklist
+1. Define request/response types in `types.go`
+2. Write handler in `handlers.go` using `http.HandlerFunc`
+3. Add route in `routes.go`
+4. Write table-driven test in `handlers_test.go`
+5. Run `task check` before committing
+
+## Error handling pattern
+```go
+if err != nil {
+    return fmt.Errorf("descriptiveOperation: %w", err)
+}
+```
+Never log and return — do one or the other.
+
+## HTMX response pattern
+```go
+func (h *Handler) ListItems(w http.ResponseWriter, r *http.Request) {
+    items, err := h.store.List(r.Context())
+    if err != nil {
+        http.Error(w, "failed to list items", http.StatusInternalServerError)
+        return
+    }
+    if r.Header.Get("HX-Request") == "true" {

+        return
+    }
+    h.templates.Render(w, "items/index", items)
+}
+```
+
+## Dependency policy
+- Prefer stdlib: `net/http`, `encoding/json`, `database/sql`
+- Allowed without justification: `testify`, `slog`, `templ`, `sqlc`
+- Needs justification in commit message: anything else

+# Agent context — Mathias workspace
+
+<!-- Canonical root context for all AI coding agents.
+     Lives at: ~/dev/.context/AGENT.md
+     Applies to every project under ~/dev/ unless overridden.
+     
+     Run `task context:sync` from ~/dev/ to regenerate harness-specific files.
+     Project-level context in .context/PROJECT.md layers on top of this. -->
+
+## Who I am
+
+I'm Mathias, a digital product manager and technology consultant based in Sweden.
+I build software, research emerging tech, and deliver consulting engagements
+for clients under NDA. I work across AI/ML, financial automation, web applications,
+and climate/sustainability tech.
+
+## How I work with agents
+
+- I think like a product manager — I care about *why* before *how*
+- I want agents to be opinionated and push back, not just execute blindly
+- I prefer concise responses; skip ceremony and get to the point
+- When I say "build this", I mean production-quality with tests, not a demo
+- Ask me before making irreversible changes or adding heavy dependencies
+- I work with confidential client data — never send it to cloud APIs unless I explicitly say it's OK
+
+## Behavior rules
+
+These rules apply to every task across every project, regardless of harness.
+
+1. **No assumptions.** Don't hide confusion — surface it. Surface tradeoffs explicitly.
+   Think before coding; if the problem is unclear, ask or state assumptions before acting.
+2. **Minimum viable code.** Solve with the smallest change that works. Nothing
+   speculative, no "while we're here" cleanups, no premature abstractions. Simplicity first.
+3. **Surgical changes.** Touch only what the task requires. Leave unrelated code,
+   files, and formatting alone. Diffs should be small and reviewable.
+4. **Goal-driven execution.** Define clear success criteria up front for every task.
+   Loop — implement, verify, refine — until those criteria are met. Don't claim
+   completion without evidence (tests pass, command output, observed behavior).
+5. **Trunk-Based Development — commit directly to main.** Every commit is one
+   logical change (one tool, one fix, one test) with passing tests. Main is always
+   deployable. Never create long-lived feature branches.
+
+   **Exception — parallel agents on same repo:** If another agent is known to be
+   actively working on the same repo simultaneously, create a short-lived branch
+   (`agent/<description>`), finish the task, and merge to main within the same
+   session. Do not leave agent branches open between sessions.
+
+   **Exception — external contributor or client four-eyes requirement:** Use
+   PR flow only when a human reviewer outside the project is required. Document
+   the reason in PROJECT.md.
+
+## Default stack
+
+| Layer | Default | Fallback | Last resort |
+|-------|---------|----------|-------------|
+| Language | Go | Python | TypeScript, Java, C |
+| UI | HTMX + Templ | Server-rendered HTML | React (only if SPA is justified) |
+| Build | Task (taskfile.dev) | Make | — |
+| Containers | Docker Compose (dev), k3s (prod) | — | — |
+| DB | PostgreSQL + sqlc | SQLite | — |
+| Search | pgvector (vector), BM25 | Qdrant (when >1M vectors or hybrid retrieval) | — |
+| Logging | slog (structured) | — | — |
+| Testing | Table-driven, testify | — | — |
+| Agents (Go) | google.golang.org/adk + pkg/litellm adapter | — | — |
+
+Exploratory: Rust, Zig — I'll tell you when I want these.
+
+## Code conventions
+
+- **Go style**: golines, gofumpt, golangci-lint
+- **Errors**: `fmt.Errorf("operation: %w", err)` — never naked, never log-and-return
+- **Naming**: stdlib conventions, no stuttering
+- **Architecture**: prefer stdlib over frameworks, constructor injection, env-var config parsed into typed structs
+- **Git**: conventional commits (`feat:`, `fix:`, `chore:`), commit directly to main,
+  one logical change per commit, CI is the quality gate
+- **Never**: long-lived feature branches, PRs for solo work, direct push without
+  passing `task check` locally first
+- **Security**: no secrets in code, govulncheck before adding deps, SOPS for encrypted config
+- **Dependencies**: prefer stdlib. testify, slog, templ, sqlc, google.golang.org/adk (agent projects only) are pre-approved; anything else needs justification in the commit message
+
+## Infrastructure
+
+Three machines on Tailscale:
+
+| Machine | Role | Key specs |
+|---------|------|-----------|
+| koala | GPU inference, heavy compute | RTX 5070, runs k3s + llama-swap + shared postgres18/pgvector |
+| iguana | Services, builds | M2 Ultra Mac |
+| flamingo | Daily driver, edge | Mac mini, ~/dev is here |
+
+- **Model routing**: LiteLLM in front of llama-swap (local) + cloud APIs (when permitted)
+- **Orchestration**: k3s cluster across all three machines
+- **Networking**: Tailscale mesh
+
+## Project landscape
+
+All development repos live at `~/dev/` (softlink from `~/Documents/local-dev/`).
+
+Organized in thematic folders:
+
+| Folder | Focus | Count |
+|--------|-------|-------|
+| `GO/` | Go web frameworks, API integrations, learning projects | ~10 |
+| `AI/` | ML research, AI frameworks (FinRL, DSPy, crawl4ai) | ~6 |
+| `AGENTS/` | Autonomous agents, coding agents, MCP servers, infra | ~15 |
+| `QKX/` | Invoice processing, financial automation, payment systems | ~13 |
+| `XT/` | Climate data, sustainability (Klimatkollen, Garbo) | ~2 |
+
+See `~/dev/PROJECT_SUMMARY.md` for detailed descriptions of each project.
+
+### Key active projects
+
+- **super-koala** (`AGENTS/`) — multi-component agent stack with LangGraph, DSPy, MCP
+- **azure-tiger** (`QKX/`) — invoice extraction → ISO 20022 payment instructions
+- **gocrwl** (`AGENTS/`) — Go web crawler with containerized deployment
+- **koala-ai-stack** (`AGENTS/`) — local AI server infrastructure management
+- **klimatkollen** (`XT/`) — Swedish municipal climate data platform
+
+## Knowledge base — actively use it
+
+A persistent brain (BM25 search + LLM-synthesised Q&A) survives across sessions,
+hosts, and harnesses. It holds 100+ hard-won entries: infra incident postmortems,
+Go pitfalls, framework gotchas, design principles, ADRs. **It is not optional
+reference material — query it actively, not just when explicitly told.**
+
+### When to query (treat as a reflex)
+
+- **Before** starting a non-trivial task — search for prior art with the symptom
+  AND the system component ("how did we solve X in Y?"). 5 seconds beats 5 hours.
+- **When debugging** — search for the error string, the stack frame, the affected
+  service. Past you may have already paid this tax.
+- **Before adopting** a pattern, library, framework, or model name — check if it
+  was tried and rejected, or what the integration footguns are.
+- **When making architectural decisions** — search for the domain + "ADR" or
+  "decision" to find prior reasoning before re-deriving it.
+- **When a recommendation feels novel** — challenge yourself: "has this been
+  documented?" The brain often has it.
+
+### When to write
+
+After you discover something that **future-you would forget** and that **isn't
+recoverable from the code, git log, or PR description alone**:
+
+- Bugs whose root cause is non-obvious and generalisable beyond this project.
+- Framework / library / model-name quirks that bit you and would bite anyone.
+- Design principles validated under fire (e.g. "every `_get` needs a `_list`").
+- Postmortems for incidents: what broke, why, how diagnosed, what to do next time.
+
+DON'T write project status, sprint progress, PR summaries, or "what I did this
+session" — those rot fast and the originals are in git/gitea anyway. Brain
+entries that age well are about *why*, *how to avoid*, and *what to do when*.
+
+### How to access (per harness)
+
+| Harness | Query | Write |
+|---------|-------|-------|
+| **Claude Code, Claude Desktop** | `brain_query` (BM25), `brain_answer` (LLM-synth + sources) MCP tools | `brain_write` MCP tool |
+| **Crush, Pi, Antigravity, other MCP-capable** | same MCP server: `ingestion-brain` (via the `mcp__*_brain__*` namespace once authenticated) | same |
+| **Anything HTTP-only (curl, scripts)** | `POST https://brain-mcp.d-ma.be/query` with `{"query":"..."}` (auth via `BRAIN_MCP_TOKEN`) | `POST .../write` with `{"content":"...","filename":"..."}` |
+| **Browser / human inspection** | `https://gitea.d-ma.be/mathias/hyperguild` → `knowledge/` and `wiki/` markdown files |
+
+- **Scoping**: defaults to `public` collection; client projects filter to `{client}` + `public`.
+- **Routing**: brain_answer's LLM uses berget.ai as primary, iguana ollama as
+  fallback. Both are configurable in the `supervisor/ingestion-deployment.yaml`
+  on the koala k3s cluster; don't hardcode local-only model names into the
+  berget URL (see knowledge entry on namespace mismatches).
+
+### Quick reflex checks
+
+If you find yourself about to say any of these out loud, you owe yourself a brain query first:
+
+- "I think the issue might be..."
+- "Let me try X and see..."
+- "I'll just write a script to..."
+- "This is probably a new bug..."
+- "Has anyone done this before?" — *yes, probably, go check.*
+
+## Client work rules
+
+When working on a project tagged with a client name:
+1. Never send code, data, or context to cloud APIs — use local models only
+2. Never reference other client projects or their data
+3. Keep all artifacts within the client's git org / directory
+4. Treat everything as confidential unless told otherwise
+
+## Harness-agnostic principles
+
+This context is designed to work with any AI coding tool:
+- Claude Code, Cursor, Aider, Open WebUI, Charmbracelet Mods/Crush
+- Pi Coding Agent, Mistral Vibe, Antigravity
+- Any tool that accepts a system prompt or reads a markdown context file
+
+The canonical source is always `.context/AGENT.md` (root) and `.context/PROJECT.md` (per-project).
+Derived files are committed (see *How context propagates* below) so a `git pull` on any host yields full agent context with no setup.
+
+## How context propagates
+
+Canonical sources of truth:
+- Universal: `~/dev/.context/AGENT.md` (this file)
+- Project: `<repo>/.context/PROJECT.md` (per-repo)
+
+Derived files (committed, regenerated by `task context:sync`):
+- `CLAUDE.md`, `AGENTS.md`, `.cursorrules`, `.aider.conventions.md`,
+  `.context/system-prompt.txt`
+
+Workflow:
+1. Edit a canonical file. Run `task context:sync`. Commit canonical and
+   derived together. Push.
+2. On any other host, `git pull` brings both. Claude Code (tree-walking)
+   uses `CLAUDE.md`; Crush / Pi / Antigravity (cwd-only) use `AGENTS.md`;
+   Cursor uses `.cursorrules`; Aider uses `.aider.conventions.md`.
+3. `task check` runs `context:sync` then asserts `git status --porcelain`
+   is empty over the derived files (catches both modified-tracked drift
+   and missing-untracked adapters). A drift fails the check with a
+   message telling you to stage the regenerated files.
+
+Behavior rules in this file and per-project rules in `PROJECT.md` apply
+unconditionally on every host, every harness.
+
+## Engineering Skills
+
+Shared engineering skills are available in `~/dev/.skills/`. Load on demand via the index.
+
+See `~/dev/.skills/SKILLS_INDEX.md` for the full list with descriptions and "use when" triggers.
+
+Key skills:
+- **TDD**: always write tests first — load `tdd` skill
+- **Code Review**: load `code-review` skill before any review
+- **SOLID/Clean Code**: load `solid` or `clean-code` skill for design work
+- **Problem first**: load `problem-analysis` skill before coding non-trivial features

+1. **`hyperguild new-project` v1** — primary next target.
+   See brain node `adr-new-project-gitea-first-github-mirror` for full flow spec.
+
+2. **Issue #19** — end-to-end mirror flow verification.
+   `repo_mirror_push` is implemented but the full flow (create repo → add push mirror → verify sync to GitHub) has not been tested manually. Do this before relying on it in production.

+```bash
+task setup:hooks   # installs .githooks/pre-push — runs task check before every push
+task check         # context sync + lint + test + vet
+task build         # produces bin/gitea-mcp
+```
+
+This repo uses Trunk-Based Development. Commit directly to `main`. The pre-push
+hook enforces the quality gate locally; CI re-runs `task check` on every push.

+# GitOps Agent Tools — Design Spec
+
+**Date:** 2026-05-06
+**Status:** Approved
+
+## Goal
+
+Extend the Gitea MCP server with the tools an AI agent needs to drive a full GitOps development loop autonomously — reading repo state, deciding on a branching strategy, making changes, opening and merging PRs, and tagging releases — without any local git tooling.
+
+The agent selects between feature-branch and trunk-based development based on branch protection rules it reads at runtime.
+
+---
+
+## New Tools (9)
+
+All tools follow the existing pattern: one file in `internal/tools/`, one Gitea client method in `internal/gitea/`, allowlist check on `owner`, table-driven tests in both packages.
+
+### `repo_status`
+
+Convenience read tool — returns branch list, open PRs, and protection info for a target branch in a single call. Designed for the agent's first query on any repo so it can decide its strategy.
+
+**Inputs:** `owner`, `name`, `branch` (optional — defaults to repo default branch)
+**Output:** `{ branches: [...], open_prs: [...], protection: { protected, required_approvals, push_whitelist, merge_whitelist } }`
+**Implementation:** calls `ListBranches` + `ListPullRequests(state=open)` + `GetBranchProtection` internally, composes result. No new Gitea API surface.
+
+---
+
+### `branch_list`
+
+**Inputs:** `owner`, `name`, `page` (optional), `limit` (optional, default 30)
+**Output:** array of `{ name, sha }`
+**Gitea endpoint:** `GET /api/v1/repos/{owner}/{repo}/branches`
+
+---
+
+### `branch_delete`
+
+**Inputs:** `owner`, `name`, `branch`
+**Output:** confirmation message
+**Gitea endpoint:** `DELETE /api/v1/repos/{owner}/{repo}/branches/{branch}`
+**Error handling:** 403 from Gitea (protected branch) surfaced as a descriptive error.
+
+---
+
+### `branch_protection_get`
+
+**Inputs:** `owner`, `name`, `branch`
+**Output:** `{ protected, required_approvals, push_whitelist, merge_whitelist }`
+**Gitea endpoint:** `GET /api/v1/repos/{owner}/{repo}/branch_protections/{branch}`
+**Error handling:** 404 → return `{ protected: false }`, not an error. Allows agent to make clean boolean decisions.
+
+---
+
+### `pr_list`
+
+**Inputs:** `owner`, `name`, `state` (`open`/`closed`/`all`, default `open`), `head` (optional branch filter), `page`, `limit`
+**Output:** array of `{ number, title, state, head_branch, base_branch, draft, html_url }`
+**Gitea endpoint:** `GET /api/v1/repos/{owner}/{repo}/pulls`
+
+---
+
+### `pr_merge`
+
+**Inputs:** `owner`, `name`, `index`, `style` (`merge`/`squash`/`rebase`, default `merge`), `merge_message_title` (optional), `merge_message_field` (optional)
+**Output:** `{ merged: true, commit_sha }` — if Gitea returns 204 No Content (some merge styles), output is `{ merged: true }` without `commit_sha`.
+**Gitea endpoint:** `POST /api/v1/repos/{owner}/{repo}/pulls/{index}/merge`
+**Error handling:** 405 (checks failing) and 409 (merge conflict) passed through with the Gitea error message intact so the agent understands why it failed.
+
+---
+
+### `dir_list`
+
+**Inputs:** `owner`, `name`, `path` (empty string = repo root), `ref` (optional branch/tag/SHA)
+**Output:** array of `{ name, path, type (file|dir|symlink), sha, size }`
+**Gitea endpoint:** `GET /api/v1/repos/{owner}/{repo}/contents/{path}`
+**Note:** same endpoint as `file_read` but returns an array when `path` is a directory. Client detects response shape (array vs object). If called on a file path, returns a descriptive error: `"path is a file, not a directory — use file_read"`.
+
+---
+
+### `file_delete`
+
+**Inputs:** `owner`, `name`, `path`, `branch`, `message`, `sha` (required — current blob SHA)
+**Output:** `{ commit_sha, html_url }`
+**Gitea endpoint:** `DELETE /api/v1/repos/{owner}/{repo}/contents/{path}`
+
+---
+
+### `tag_create`
+
+**Inputs:** `owner`, `name`, `tag` (tag name), `target` (branch name or commit SHA), `message` (optional — creates annotated tag if set)
+**Output:** `{ tag, commit_sha, html_url }`
+**Gitea endpoint:** `POST /api/v1/repos/{owner}/{repo}/tags`
+
+---
+
+## Gitea Client Methods
+
+New methods on `gitea.Client`:
+
+| Method | Endpoint | HTTP verb |
+|--------|----------|-----------|
+| `ListBranches(ctx, owner, repo, page, limit)` | `/api/v1/repos/{owner}/{repo}/branches` | GET |
+| `DeleteBranch(ctx, owner, repo, branch)` | `/api/v1/repos/{owner}/{repo}/branches/{branch}` | DELETE |
+| `GetBranchProtection(ctx, owner, repo, branch)` | `/api/v1/repos/{owner}/{repo}/branch_protections/{branch}` | GET |
+| `ListPullRequests(ctx, owner, repo, state, head, page, limit)` | `/api/v1/repos/{owner}/{repo}/pulls` | GET |
+| `MergePullRequest(ctx, owner, repo, index, args)` | `/api/v1/repos/{owner}/{repo}/pulls/{index}/merge` | POST |
+| `ListContents(ctx, owner, repo, path, ref)` | `/api/v1/repos/{owner}/{repo}/contents/{path}` | GET |
+| `DeleteFile(ctx, owner, repo, path, args)` | `/api/v1/repos/{owner}/{repo}/contents/{path}` | DELETE |
+| `CreateTag(ctx, owner, repo, args)` | `/api/v1/repos/{owner}/{repo}/tags` | POST |
+
+---
+
+## Architecture
+
+No structural changes. Each new tool is:
+- One file: `internal/tools/<tool_name>.go` + `internal/tools/<tool_name>_test.go`
+- One client method: `internal/gitea/<domain>.go` (added to existing domain files where logical)
+- Registered in `cmd/gitea-mcp/main.go`
+
+`repo_status` is the only tool with internal composition — it calls three client methods and merges their results. It has no dedicated client method of its own.
+
+New client methods go in existing domain files:
+- Branch methods → `internal/gitea/files.go` (already has `BranchExists`, `CreateBranch`)
+- PR methods → `internal/gitea/pulls.go`
+- Contents (dir_list, file_delete) → `internal/gitea/files.go`
+- Tags → new `internal/gitea/tags.go`
+
+---
+
+## Testing
+
+Pattern: table-driven tests with a `httptest.NewServer` mock, same as `file_write_branch_test.go`.
+
+Each tool covers:
+- Happy path
+- 404 response
+- Allowlist rejection
+- Tool-specific edge cases:
+  - `branch_delete`: 403 protected branch
+  - `branch_protection_get`: 404 → `{protected: false}` not error
+  - `dir_list`: file path → descriptive error
+  - `pr_merge`: 405 checks failing, 409 merge conflict
+  - `repo_status`: any one sub-call failing propagates the error
+
+---
+
+## Agent Decision Flow (Reference)
+
+```
+1. repo_status(owner, name)
+   → if branch.protected && required_approvals > 0:
+       use feature-branch workflow
+   → else:
+       use trunk-based workflow
+
+Feature-branch workflow:
+  file_write_branch (auto-creates branch)
+  → pr_create
+  → [wait for CI via workflow_run_status]
+  → pr_merge
+  → branch_delete
+
+Trunk-based workflow:
+  file_write_branch(branch=main)
+  → [optionally] tag_create
+
+Post-merge (either):
+  → [optionally] tag_create to trigger deployment
+```
