hyperguild

An MCP server that acts as a disciplined AI supervisor for Claude Code sessions. Instead of letting Claude Code do whatever it wants, hyperguild enforces structured workflows (TDD red/green/refactor), logs every session, and accumulates learnings into a searchable brain.

How it works

Your Claude Code session (in any project)
    │
    │  MCP over HTTP (Tailscale)
    ├──▶ supervisor  :3200 (NodePort 30320 on koala) — skill workers: tdd, debug, spec, …
    ├──▶ routing     :3210 (NodePort 30310 on koala) — Mode 2 only: review, debug, retrospective, trainer
    └──▶ brain       :3300 (NodePort 30330 on koala) — brain_query, brain_write, brain_ingest, session_log
                       │
                       └─ also serves the legacy REST endpoints (/query, /write, /ingest, …)

Phase 1 tools (available now)

Tool	What it does
tdd_red	Writes a failing test for a spec, verifies it fails
tdd_green	Writes the minimal implementation to make tests pass
tdd_refactor	Cleans up implementation while keeping tests green
session_log	Appends a structured entry to the session JSONL log
retrospective	Reads the session log, identifies novel learnings, writes to brain/raw/
brain_query	Full-text search over brain/wiki/
brain_write	Writes a note to brain/raw/ (with optional YAML frontmatter)
tier	Returns the current connectivity tier (1=cloud, 2=LAN, 3=offline)

Start the servers

# Requires goreman: go install github.com/mattn/goreman@latest
task start    # starts ingestion (:3300) + supervisor (:3200) via goreman
task stop     # kills both by port

Connect a project

Create .mcp.json in your project root:

{
  "mcpServers": {
    "supervisor": {
      "type": "http",
      "url": "http://koala:30320/mcp"
    },
    "brain": {
      "type": "http",
      "url": "http://koala:30330/mcp"
    }
  }
}

Two MCP servers are exposed today, both reachable over Tailscale:

• supervisor at koala:30320 — skill workers (tdd_red/green/refactor, review, debug, spec, retrospective, trainer, tier).
• brain at koala:30330 — knowledge access (brain_query, brain_write, brain_ingest, brain_ingest_raw) and session_log. Hosted by the ingestion service directly, no separate pod.

No local binary or stdio shim is required — Claude Code talks to both via HTTP.

Open Claude Code in your project — run /mcp to confirm both servers are listed.

A typical TDD session

1. Call tdd_red    → spec in, failing test file out
2. Call tdd_green  → test path in, implementation out
3. Call tdd_refactor → impl + test in, cleaned code out
4. Call session_log  → log each phase result
5. Call retrospective → extracts learnings → brain/raw/
6. Review brain/raw/, move worthy notes to brain/wiki/concepts/
7. Future sessions: call brain_query to retrieve relevant context

Tier detection

The supervisor probes connectivity at call time:

Tier	Label	Condition
1	full-online	Can reach api.anthropic.com
2	lan-only	Can reach LiteLLM but not Anthropic
3	airplane	No external connectivity

Key env vars

Variable	Default	Purpose
INGEST_BRAIN_DIR	../brain	Brain directory for ingestion server
INGEST_PORT	3300	Ingestion server port
SUPERVISOR_CONFIG_DIR	./config/supervisor	Skill discipline files
SUPERVISOR_SESSIONS_DIR	./brain/sessions	JSONL session logs
INGEST_BASE_URL	http://localhost:3300	Supervisor → ingestion
LITELLM_BASE_URL	—	LiteLLM proxy for Tier 2 model routing
SUPERVISOR_MCP_TOKEN	—	Optional bearer token for the supervisor MCP HTTP endpoint; when empty, no auth is enforced
ROUTING_PORT	3210	Routing pod's listen port
ROUTING_MCP_TOKEN	—	Optional bearer token for the routing MCP HTTP endpoint
BRAIN_URL	http://ingestion.supervisor:3300	Routing pod → brain (in-cluster)
HYPERGUILD_FAST_MODEL	koala/qwen35-9b-fast	Fast model for high-pass-rate skill calls
HYPERGUILD_THINKING_MODEL	iguana/gemma4-26b	Thinking model for low-pass-rate skill calls
HYPERGUILD_ROUTE_LOCAL_FLOOR	0.90	At/above pass rate, route to fast model
HYPERGUILD_ROUTE_LOCAL_CEIL	0.70	Below pass rate, route to thinking model. Between CEIL and FLOOR is the sample band.
HYPERGUILD_PASS_RATE_TTL_SECONDS	60	Per-skill pass-rate cache TTL

Operator note: LiteLLM at LITELLM_BASE_URL must register both HYPERGUILD_FAST_MODEL and HYPERGUILD_THINKING_MODEL for routing to do useful work. If a model is missing, LiteLLM returns 4xx, the routing pod's fast route fails, the fail-open retry on the thinking model likely also fails (since both are missing), and the only signal is final_status: "fail" on _routing entries in the brain.

Phase 2 (planned)

• review skill — structured code review with iron law enforcement
• debug skill — hypothesis-driven debugging sessions
• spec skill — generates specs from conversations
• trainer — extracts SFT/DPO pairs from session logs for fine-tuning
