Agent Conductor

AGENTS.md in, governed agent team out.

Agent Conductor is an MCP server that turns the two conventions the coding-agent ecosystem has converged on — AGENTS.md operating manuals and SKILL.md skills — from passive documentation into an active orchestration layer, with a consensus-hardened decision engine gating high-stakes changes.

The problem

Every serious agent tool — Claude Code, Cursor, Copilot, Codex, Gemini CLI — now reads an AGENTS.md at the repo root and a catalog of SKILL.md files. But both conventions are honor-system prose:

• Nothing compiles the contract. The non-negotiable rules, layer boundaries, and verification checklists live as markdown the agent may or may not internalize.
• Nothing gates the decision. An agent that's about to rewrite your scoring model proceeds with the same confidence as one renaming a variable.
• Nothing verifies the checklist ran. "Run npm test before handing off" is a suggestion, not a gate.

Conductor makes the conventions executable — without asking any agent tool to change. It ships as a standard MCP server, so anything that speaks MCP gets contract compilation, skill discovery, and decision gating for free.

Three capability groups:

1. Contract — compile an AGENTS.md into structured mission, non-negotiable rules, layer do/don't boundaries, verification gates, skill recommendations, and an out-of-scope list.
2. Skills — discover SKILL.md skills across project and personal scopes with progressive disclosure: metadata costs ~100 tokens, bodies load only on demand.
3. Decision — gate work through the Consensus Hardening Protocol: a cheap R0 sanity gate before work starts, and an adversarial foundation-attack pass before a high-stakes change locks.

Quick start

Requirements: Node 23+ (runs TypeScript natively) and Python 3.9+ (stdlib only — the engine needs no pip installs).

git clone https://codeberg.org/cubiczan/agent-conductor.git
cd agent-conductor
npm install
npm test            # TypeScript tests (parser, skills, multi-root, live engine bridge)
npm run test:engine # Python bridge protocol tests
npm run build

Register with Claude Code:

claude mcp add agent-conductor -- node /path/to/agent-conductor/dist/index.js

Or in any MCP client's JSON config:

{
  "mcpServers": {
    "agent-conductor": {
      "command": "node",
      "args": ["/path/to/agent-conductor/dist/index.js"]
    }
  }
}

Set CONDUCTOR_PYTHON if your Python 3 lives somewhere other than python3.

Then, from any project that has an AGENTS.md:

"Load this project's agent contract, list its verification gates, and run a decision_adversary pass on the change I'm about to make."

Tool reference

contract_load

Compile an AGENTS.md (or CLAUDE.md) into a structured contract. Accepts a file path, a project directory, an explicit roots list, or a rootsFile map; defaults to the current working directory. Multi-root workspaces emit one contract whose layer table and verification commands are merged. Section bodies stay off this tool so callers remain inside progressive- disclosure budgets (metadata + structured fields only).

// input
{ "path": "examples/pipeline-pulse" }

// output (abridged — real output from the bundled example)
{
  "source": "examples/pipeline-pulse/AGENTS.md",
  "title": "AGENTS.md — Pipeline Pulse CRM",
  "mission": "Pipeline Pulse CRM is a lightweight, local-first pipeline review dashboard...",
  "rules": [
    "Deterministic logic — same inputs → same scores, labels, and summaries...",
    "Logic in crm.js — keep main.js thin (fetch, render, events).",
    "... (6 total)"
  ],
  "layers": [
    { "layer": "src/crm.js", "role": "Domain logic",
      "do": "Deterministic scoring, filtering, summaries", "dont": "DOM manipulation" }
  ],
  "gates": [
    { "name": "Code change checklist", "commands": ["npm test"], "notes": "" },
    { "name": "Before completion", "commands": [], "notes": "npm test — all green...\n..." }
  ],
  "skills": [
    { "task": "CRM scoring / forecast changes", "skill": "obra/test-driven-development",
      "url": "https://github.com/obra/superpowers/...", "why": "Tests-first changes to deterministic logic" }
  ],
  "outOfScope": ["External CRM integrations (Salesforce, HubSpot, etc.)", "..."],
  "sectionCount": 28
}

The parser is lossless: sections it doesn't recognize are preserved verbatim, so nothing in an unconventional AGENTS.md is dropped.

contract_verification

Returns only the verification gates — the named checklists and shell commands that must pass before work is handed off. Pair it with your agent's workflow: run the commands, confirm success, then declare done. Accepts the same single-root or multi-root inputs as contract_load.

skills_list

Discover SKILL.md skills visible from a project root or a declared multi-root workspace. Metadata only. Extra source roots outside a module directory are included when they appear in the roots list or map.

// input
{ "projectRoot": "examples/pipeline-pulse" }

// output
{
  "skills": [
    {
      "name": "pipeline-scoring",
      "description": "Explain and modify scoreDealRisk weights in src/crm.js with matching test updates...",
      "version": "0.1.0",
      "scope": "project"
    }
  ]
}

Search order (first hit per skill name wins). In a multi-root workspace the project rows run for each declared root, then personal scopes run once:

skill_load

Load the full SKILL.md body for one named skill — the on-demand half of progressive disclosure. Call it only when the task matches the skill's description.

decision_gate

The Consensus Hardening Protocol R0 gate: the cheapest, highest-leverage check, run before doing the work.

// input
{ "solvable": true, "scoped": false, "valid": true, "worth_it": true }

// output
{ "verdict": "HALT", "results": { "Solvable": "PASS", "Scoped": "FATAL", "Valid": "PASS", "Worth_it": "PASS" } }

Any FATAL answer halts: stop and reframe before burning tokens on a problem that isn't scoped, isn't understood, or isn't worth solving.

decision_adversary

A one-shot adversarial pass for high-stakes changes: CHP attacks the claim's foundations, scores them 0–100, and returns devil's-advocate findings plus a session status.

// input
{
  "claim": "Change scoreDealRisk stale-activity weight from 20 to 30",
  "context": "Tests updated; label distribution checked against fixture"
}

// output
{
  "status": "EXPLORING",          // or HALT / REFRAME_REQUIRED
  "foundation_score": 77,
  "findings": [
    "Treat every financial number as unverified until tied to source data.",
    "Require explicit flip criteria for any provisional recommendation."
  ],
  "verification_failures": ["PENDING third-party validation"],
  "report": "## TriangulationRunner Adversary Pass\n..."
}

Statuses map to the CHP decision lifecycle (EXPLORING → PROVISIONAL_LOCK → LOCKED, with HALT and REFRAME_REQUIRED exits): EXPLORING means the claim survived the attack and work may proceed toward a lock; HALT/REFRAME_REQUIRED mean the foundations failed.

engine_status

Health-check the Python engine subprocess. Returns { ok, engine: "chp", version }.

What the parser recognizes

contract_load is convention-based, not schema-based. It extracts the patterns AGENTS.md files in the wild actually use:

Headings inside code fences are ignored; tables tolerate emphasis in headers; markdown links and emphasis are stripped from extracted text.

Writing skills

A skill is a directory containing SKILL.md with YAML frontmatter:

---
name: pipeline-scoring
description: Explain and modify scoreDealRisk weights in src/crm.js with matching test updates. Use when changing deal risk scoring, risk labels, or forecast thresholds.
version: 0.1.0
tools: [Read, Edit, Bash]
---

# Pipeline Scoring

Step-by-step instructions the agent follows when the task matches...

Quality bar (inherited from the awesome-agent-skills standards): third-person description with matchable keywords, metadata around 100 tokens, body under 500 lines, no machine-specific absolute paths, declare only the tools the skill needs.

The bundled examples:

• examples/pipeline-pulse — a complete real-world AGENTS.md plus a project-scoped skill (single-root compile).
• examples/multimodule — a Gradle-style extra source root: skills live under shared/, outside modules/billing.

Monorepo cookbook

Naive loaders walk only the directory they were pointed at. That breaks the same way a Gradle module breaks when a sourceSet points outside the module (srcDirs = ['src/main/java', '../shared/src']): the extra tree is real work, but it is not inside the module dir.

Declare every extra root. Conductor fails closed if one is missing — it will not invent a root or silently skip it.

1. Write a roots map

Canonical locations (first hit wins):

JSON object (ids optional):

{
  "roots": [
    { "id": "workspace", "path": "." },
    { "id": "billing", "path": "modules/billing" },
    { "id": "shared", "path": "shared" }
  ]
}

JSON array of paths:

[".", "modules/billing", "shared"]

Line-oriented map (# comments allowed):

workspace: .
billing: modules/billing
shared

Relative paths resolve against the map file's directory.

2. Keep skills on the extra root

examples/multimodule/
├── conductor.roots.json
├── AGENTS.md                    # workspace layers + `npm test`
├── modules/billing/AGENTS.md    # module layers + `npm -C modules/billing test`
└── shared/.conductor/skills/shared-ledger/SKILL.md

modules/billing alone cannot see shared-ledger. After the map is declared, skills_list and skill_load walk every root, then personal scopes, with first-hit-wins shadowing.

3. Call the tools

// Auto-detect a roots map under a directory
{ "path": "examples/multimodule" }

// Explicit list (relative paths resolve against `path` or cwd)
{ "path": "examples/multimodule", "roots": [".", "modules/billing", "shared"] }

// Explicit map file
{ "rootsFile": "examples/multimodule/conductor.roots.json" }

contract_load still returns a summary without section bodies; contract_verification still returns gates only; skills_list still returns frontmatter metadata. Single-root projects without a map file — including examples/pipeline-pulse — keep the previous compile path.

Development

npm test            # TypeScript tests — includes a live engine round-trip
npm run test:engine # Python-side protocol tests
npx tsc --noEmit    # type check
npm run build       # emit dist/
npm run dev         # run the server from source (Node type stripping)

House rules (the full set is in this repo's own AGENTS.md):

1. stdout is sacred — the MCP transport owns it; all logging goes to stderr on both sides of the bridge.
2. Zero new runtime dependencies — only @modelcontextprotocol/sdk and zod; markdown and frontmatter parsing stay hand-rolled and tested.
3. Erasable TypeScript only — source must run under Node's type stripping (no enums, no parameter properties).
4. Vendor discipline — engine/vendor/cme/ stays byte-identical to upstream except the documented __init__.py patch; engine behavior changes belong in bridge.py.

Provenance

Conductor deliberately reuses proven components rather than rewriting them:

See engine/vendor/NOTICE.md for vendoring details and ARCHITECTURE.md for the reasoning behind the two-language design.
