agent-chorus AGENTS.md

agent-chorus AGENTS.md is an instructions file for Codex, OpenCode from cote-star/agent-chorus. It costs 1,511 tokens per session, scanned A, original, MIT.

Repository instructions for Agent Chorus that route each task through structured context files, completeness rules, reporting rules, and an allowed search area. A monorepo is a repository containing multiple related parts or projects.

In plain words
What is it for?
Use them when investigating the codebase, selecting the right task procedure, checking required files, or handling a missing or outdated context pack.
Why use it?
They limit an agent's search to the files relevant to the task, which makes work more focused and helps prevent missed project rules.

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-chorus 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 4d 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.

  1. Read .agent-context/current/routes.json to identify task type
  2. Load contracts from .agent-context/current/completeness_contract.json + .agent-context/current/search_scope.json
  3. Search ONLY within scoped directories defined in search_scope.json
  4. Do not open repo source files before step 3

Context Pack

When asked to understand this repository:

  1. Read .agent-context/current/00_START_HERE.md.
  2. Read .agent-context/current/routes.json.
  3. Identify the active task type in routes.json.
  4. Read the matching entries in completeness_contract.json, reporting_rules.json, and search_scope.json.
  5. Search ONLY within the directories listed in search_scope.json for your task type.
  6. Use verification_shortcuts to check specific line ranges instead of reading full files.
  7. Do not enumerate files in directories marked exclude_from_search.
  8. Do not open repo files before those steps unless a referenced structured file is missing.

If .agent-context/current/routes.json is missing, fall back to the markdown pack only.

Agent Instructions For This Repo

Naming convention: Use chorus agent-context ... commands. Legacy npm wrappers (npm run agent-context:*) are still available in this repo.

End-to-End Understanding Shortcut

When asked to understand this repository end-to-end:

  1. Read .agent-context/current/00_START_HERE.md first.
  2. Use .agent-context/current/manifest.json + 20_CODE_MAP.md to target only relevant source files.
  3. Open additional files only when the current task requires deeper proof.

If Context Pack Is Missing or Stale

Run:

chorus agent-context init
# ...fill details...
chorus agent-context seal

Main Push Context Sync

Install hook once:

chorus agent-context install-hooks

The pre-push hook prints an advisory warning when a push targets main and changes context-relevant files. It never auto-builds or blocks the push.

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.
