agent-conductor: Instructions file for Codex

AGENTS.md

agent-conductor AGENTS.md is an instructions file for Codex, OpenCode from icohangar-ops/agent-conductor. It costs 762 tokens per session, scanned A, original, MIT.

Repository instructions for AI coding agents working on Agent Conductor. They describe its mission, architecture, engineering rules, and non-negotiable behaviours.

In plain words
What is it for?
Guide development of Agent Conductor, including AGENTS.md parsing, skill discovery, decision-engine communication, dependency pinning, and regression tests.
Why use it?
They tell agents how to preserve instructions during parsing, load skills efficiently, and keep tool communication usable. This reduces accidental changes to the orchestration system’s core contracts.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is icohangar-ops/agent-conductor's own configuration. It tells Codex and OpenCode how to work on agent-conductor itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-conductor configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-conductor AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Agent Conductor

Guidance for AI coding agents working in this repository. (Yes — Conductor's own contract compiles with Conductor: contract_load on this file.)

Mission

Agent Conductor turns AGENTS.md operating manuals and SKILL.md skills into an active orchestration layer over MCP, with the Consensus Hardening Protocol gating high-stakes decisions. Agents should keep the parser lossless, the dependency surface near zero, and the MCP stdout stream protocol-clean.

Architecture

Layer Role Do Don't
src/contract/ Contract compilation Extract recognized AGENTS.md patterns; preserve unknown sections Drop content the parser doesn't understand
src/contract/workspace.ts Multi-root compile Walk declared roots; merge layer tables and gates; fail closed Invent or skip a root the map declared
src/skills/ Skill discovery Frontmatter-only metadata on discovery; bodies on demand Load bodies eagerly
src/budget/ Bounded-run spend control Fail-closed ceilings, ledger before/after, compose CHP R0 Invent a parallel policy engine or a new package
src/engine/ + engine/bridge.py Decision engine boundary Speak newline-delimited JSON over child stdio Print logs to stdout on either side
engine/vendor/cme/ Vendored CHP core Keep byte-identical to upstream except __init__.py Edit vendored logic — fix upstream instead
test/ Regression guard Test against the real example fixture Mock the Python engine in engine tests

Engineering rules

Non-negotiables

  1. stdout is sacred — MCP transport owns process stdout; all logging goes to stderr on both sides of the bridge.
  2. Zero new runtime dependencies — markdown/frontmatter parsing stays hand-rolled; only the MCP SDK and zod are allowed.
  3. Lossless compilation — unrecognized AGENTS.md sections must survive into contract.sections.
  4. Erasable TypeScript only — source must run under Node's type stripping (no enums, no parameter properties); tsconfig enforces erasableSyntaxOnly.
  5. Vendor discipline — engine/vendor/cme/ is upstream's code; changes belong upstream or in bridge.py.
  6. Engine runs on stdlib Python 3.9+ — no pip installs in the engine path.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
