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

This is bo0tzz/pgmqtt's own configuration. It tells Codex and OpenCode how to work on pgmqtt 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 pgmqtt 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

pgmqtt 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 25d 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.

AGENTS.md

Operational notes for working in this repo as an autonomous agent (Claude Code or otherwise). Designed as a load-bearing playbook: read it before your first commit, link it from PRs that follow non-obvious workflows.

Validation tier model

Three tiers, additive (tier3 ⊃ tier2 ⊃ tier1). Wall-clock + exact bug coverage are documented in scripts/validate-timings.md. Short version:

Tier When to run Wall clock Run command
tier1 After every code change ~10s make validate TIER=tier1
tier2 Before commit / before PR ~6m make validate TIER=tier2 PAHO=/tmp/paho-testing
tier3 Before tag / weekly nightly ~12–18m make validate TIER=tier3 PAHO=/tmp/paho-testing

What each tier closes that the prior tier misses:

  • tier1 — compile / vet / race-light unit tests / chart lint+template+ strict parse. Catches static bugs, helm rendering issues (typoed values keys, scientific-notation in int fields, duplicate label keys that helm emits but Flux/kustomize reject), small-package data races.
  • tier2 — full unit suite against a testcontainer Postgres + paho v3+v5 conformance against a single broker. Catches SQL path regressions and MQTT protocol shape bugs (reason codes, retain, will-delay, takeover ordering).
  • tier3 — multi-broker paho via kind + 60s soak smoke. Catches cross- pod fanout bugs, deploy-shape regressions (helm-rendered manifests applied to a real apiserver), sustained-load issues.

In CI:

  • ci.yml — covers tier1's surface on every PR (vet, test, test-race, helm lint, kind-based smoke). Already green is your gate to merge. Dependency scanning lives in its own govulncheck (deps) job so an upstream advisory doesn't read as a test failure; it still gates merge. For the same reason validate.sh doesn't run govulncheck in any tier; pass --vulncheck (or make validate ... VULNCHECK=1) to add it.
  • conformance-nightly.yml — runs tier2 daily at 03:00 UTC. Doesn't gate PRs; informational regression detector.
  • soak-weekly.yml — runs an in-cluster soak (and tier3 paho multi-broker, best-effort) Mondays 04:00 UTC. Fails on any QoS≥1 loss/dups.

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.
