claude-code-gauntlet: Instructions file for Codex

AGENTS.md

claude-code-gauntlet AGENTS.md is an instructions file for Codex, OpenCode from liatrio-labs/claude-code-gauntlet. It costs 689 tokens per session, scanned A, original, Apache-2.0.

A set of repository instructions for Claude Code, an AI coding assistant, working on the claude-code-gauntlet plugin. It explains project rules, directory-specific guidance, scripts, and tests.

In plain words
What is it for?
Use it when editing the plugin’s workflows, scripts, agents, or tests. It helps decide where changes belong and how to verify them.
Why use it?
It gives the assistant the project context and constraints needed to make changes that fit the repository. It also reduces errors such as adding npm files or ignoring local 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

claude-code-gauntlet 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 16d 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 — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

claude-code-gauntlet is a Claude Code marketplace plugin: a multi-agent code review pipeline. There is no server, database, or Docker. Running it means running the suites below.

workflows/ and agents/ each carry a short AGENTS.md of their own. CONTRIBUTING.md holds the CI coverage gates and everything else a human contributor needs.

Design

  • Build the mechanism, not the instruction. Whatever code, a schema, a data structure, or a removed capability can enforce, it must. Prose in a prompt or agent file is the fallback.
  • "Add more text" is a design smell. If that is the fix under consideration, change the shape.
  • Extending should cost one edit. If a new dimension, field, or agent takes coordinated edits across several files, fix the shape instead of documenting the ritual.

Commands

python -m pytest tests/ -q               # pipeline scripts
python -m pytest bench/tests/ -q         # benchmark harness
node --test workflows/test/*.test.js     # Node 24; a bare directory is not a valid target
node workflows/build.js                  # after editing workflows/src; commit the bundle
python3 workflows/test/tools/biome_check.py
pre-commit run --all-files               # the lint gate

pre-commit sees tracked files only, so git add a new file before trusting a green run. markdownlint-fix fixes in place and then reports failure: re-stage and re-run.

Constraints

  • No package.json, lockfile, or node_modules. scripts/ is stdlib-only Python 3.10, and the shipped bundle has zero dependencies.
  • Language-agnostic. Never assume the reviewed codebase's language: exclude non-source directories, never include by extension.
  • Python shape. A JSON wire shape is a TypedDict, an internal record is a frozen slotted dataclass, a closed vocabulary is a Literal. scripts/*.py are thin entry files; logic lives in scripts/gauntlet/.
  • New and rewritten tests are pytest functions that prove a behaviour once, at the boundary callers use. A regression test must fail against the bug it names: mutate the whole mechanism and watch it go red, because a partial mutation falls through to a neighbouring fallback and passes.
  • Comments say why. No history, dates, or issue numbers in code; those belong in the PR.
  • Never write the literal skip-ci token in a commit message, even when writing about it. GitHub Actions scans the whole message and silently skips every workflow.
  • Session scratch stays out of the tree. Plans, memos, and handoff notes go in the PR or the issue. Coverage data files stay out too: set COVERAGE_FILE to a temp 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.
