# Agent Conductor

**AGENTS.md in, governed agent team out.**

Agent Conductor is an [MCP](https://modelcontextprotocol.io) server that turns
the two conventions the coding-agent ecosystem has converged on —
[`AGENTS.md`](https://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.

- **License:** MIT
- **Status:** v0.1 — working scaffold; see [Roadmap](#roadmap)

## 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](https://codeberg.org/cubiczan/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).

```bash
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:

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

Or in any MCP client's JSON config:

```json
{
  "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).

```jsonc
// 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.

```jsonc
// 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:

| Priority | Path | Scope |
|----------|------|-------|
| 1 | `<root>/.conductor/skills/*/SKILL.md` | project |
| 2 | `<root>/.claude/skills/*/SKILL.md` | project |
| 3 | `<root>/.cursor/skills/*/SKILL.md` | project |
| 4 | `~/.claude/skills/*/SKILL.md` | personal |
| 5 | `~/.cursor/skills/*/SKILL.md` | personal |

### `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.

```jsonc
// 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.

```jsonc
// 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:

| Contract field | Source convention |
|----------------|-------------------|
| `mission` | First `Mission` / `Purpose` / `Overview` section |
| `rules` | List items under `Non-negotiables` > `Engineering rules` > generic `rules` (priority-ordered so a generic "Product rules" section never shadows explicit non-negotiables) |
| `layers` | First table with a `Layer` column under an architecture-like heading |
| `gates` | Shell code blocks + list items under checklist / verification / before-completion headings |
| `skills` | Tables with `Task` / `Skill` / `Why` columns; links resolved to text + URL |
| `outOfScope` | List under an out-of-scope / non-goals heading |
| `sections` | Everything, verbatim — the lossless fallback |

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:

```markdown
---
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](https://github.com/VoltAgent/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](examples/pipeline-pulse/AGENTS.md) — a complete
  real-world AGENTS.md plus a project-scoped skill (single-root compile).
- [examples/multimodule](examples/multimodule/AGENTS.md) — 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):

| File | When to use |
|------|-------------|
| `.conductor/roots.json` | Next to `.conductor/skills` |
| `conductor.roots.json` | Repo-root convenience |
| `.conductor/roots` / `conductor.roots` | Line-oriented alternative |

JSON object (ids optional):

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

JSON array of paths:

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

Line-oriented map (`#` comments allowed):

```text
workspace: .
billing: modules/billing
shared
```

Relative paths resolve against the map file's directory.

### 2. Keep skills on the extra root

```text
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

```jsonc
// 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.

## Project structure

```

## Development

```bash
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](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`.

## Roadmap

| Version | Theme | Scope |
|---------|-------|-------|
| **v0.2** | Enforcement | Execute `contract_verification` gates as real subprocesses and return pass/fail evidence — turning "reads the contract" into "enforces the contract" |
| **v0.3** | Orchestration | Map contract layers onto CHP `MeshAgent` capabilities (`produces`/`consumes`) and expose full multi-agent deliberation sessions over MCP |
| **v0.4** | Registry | Install vetted skills from remote catalogs (awesome-agent-skills format) with source-review prompts |
