vibes AGENTS.md is an instructions file for Codex, OpenCode from rcarmo/vibes. It costs 617 tokens per session, scanned A, original, MIT.

Repository instructions for Vibes, a project with a Go backend, a Bun-built frontend, and end-to-end tests.

In plain words
What is it for?
It guides coding agents through frontend builds, Go builds, linting, tests, serving, development, and Playwright end-to-end checks.
Why use it?
Generated frontend files, build commands, and validation steps must be handled consistently to avoid editing the wrong files or skipping checks.

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

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

vibes 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 21d 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.

Vibes Python

Cache and scratch paths

The canonical project name is vibes. scripts/project-tmp.sh resolves the root once before Make exports child temp variables. An absolute PROJECT_TMP_BASE selects <base>/vibes; the compatible absolute PROJECT_TMP_ROOT must end in /vibes. If both are supplied they must agree. Invalid, unsafe or unusable overrides fail without fallback. CI selects usable ${RUNNER_TEMP}/vibes, then the original ${TMPDIR}/vibes, then /tmp/vibes, even when /workspace/tmp exists. Local runs prefer writable /workspace/tmp/vibes, then /tmp/vibes. The helper snapshots incoming TMPDIR as PROJECT_ORIGINAL_TMPDIR and propagates the resolved root to children. The resolver is vendored; CI needs no /workspace helper. Every selected root uses:

  • cache/<tool>/ for Python bytecode, pytest, pip, uv, Bun, npm and XDG caches.
  • build/ for disposable build output.
  • tests/ and logs/ for disposable test/log scratch where used.
  • runs/<purpose>/<run-id>/ for isolated scratch and test filesystem roots.

The Makefile exports TMPDIR, TMP, TEMP, XDG_CACHE_HOME, PIP_CACHE_DIR, UV_CACHE_DIR, BUN_INSTALL_CACHE_DIR, npm_config_cache, PYTHONPYCACHEPREFIX and pytest basetemp/cache options. Set VIBES_RUN_ID explicitly for reproducible run receipts. Direct commands must use the same paths. Never use bare /tmp, home caches or ad-hoc top-level temporary paths. Direct commands can resolve using PROJECT=vibes bash scripts/project-tmp.sh init and must propagate that root before setting TMPDIR; do not append vibes again to an already exported run-local TMPDIR.

Retained profiles, logs, receipts and datasets are evidence, not disposable scratch. Keep publication evidence under docs/evidence/; preserve external historical evidence until explicitly migrated. Cleanup may remove only confirmed inactive disposable paths beneath the resolved project root. Never delete another project's root, retained evidence or files used by active jobs. The existing clean target removes local Python bytecode/test cache only and does not delete the project scratch root or evidence.

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.
