docguard: Instructions file for Codex

AGENTS.md

docguard AGENTS.md is an instructions file for Codex, OpenCode from raccioly/docguard. It costs 4,464 tokens per session, scanned A, original, MIT.

Repository instructions for DocGuard, a JavaScript project that checks whether code changes follow documentation treated as the project’s source of truth.

In plain words
What is it for?
Use them when changing DocGuard, reading its canonical documents, recording intentional differences, or running its diagnosis and verification commands.
Why use it?
They establish a review process that reduces undocumented deviations and requires diagnostic and guard checks before changes are accepted.

Instructions file for CodexOpenCode

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

This is raccioly/docguard's own configuration. It tells Codex and OpenCode how to work on docguard 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 docguard 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

docguard 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 9d 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.

AI Agent Instructions — DocGuard

This project follows Canonical-Driven Development (CDD). Documentation is the source of truth. Read before coding. DocGuard is an official GitHub Spec Kit community extension.

Workflow

  1. Read docs-canonical/ before suggesting changes
  2. Check existing patterns in the codebase
  3. Run docguard diagnose to see what needs fixing
  4. Confirm your approach before writing code
  5. Implement matching existing code style
  6. Log any deviations in DRIFT-LOG.md with // DRIFT: reason
  7. Verify with docguard guard — all checks must pass

Project Stack

  • Language: JavaScript (ES modules)
  • Runtime: Node.js 18+
  • Dependencies: One — @babel/parser (exact-pinned, optional-load); Node.js built-ins otherwise
  • Testing: node:test (built-in)
  • Distribution: npm + PyPI; the release also publishes the MCP server image to GHCR, the Claude Desktop MCPB bundle and the Homebrew tap
  • Version: see package.json (single source of truth — do not hardcode here)

Commands

docguard --help is the authoritative list (counts intentionally not hardcoded here — they drift). The surface, grouped as --help shows it:

The Daily 5 — init (bootstrap + scan), guard (CI gate, all validators), diff (doc↔code gaps; --since <ref> for changed-file impact), sync (refresh code-truth sections), score (CDD maturity 0-100).

Changes

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.
