Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

bug 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 today.

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.

Project Agent Guidelines

Module Testing Standard

  • Use docker-based test execution for module containers.
  • For module container packages, set scripts.test to build and run tests in Docker using each module's Dockerfile.test.
  • Prefer this pattern for module test commands:
docker build -f ./Dockerfile.test -t bug-module-test ../../../.. && docker run --rm --name bug-module-test-run bug-module-test npx jest --runInBand --config ./jest.config.cjs

Module Container Quick Check Profile

  • Purpose: run a quick agentic pre-commit check in chat before major module container changes are committed.
  • Use trigger phrase in chat: Run the module container quick check before commit.

Implementation Defaults

  • Rule: keep worker restart checks aligned to real config dependencies.
  • Rule: default to simple, readable implementations over maximum efficiency; only optimize for performance when there is a clear, measured requirement.
  • Rule: prefer the simplest safe fix first, with minimal code changes.
  • Rule: prefer inlined one-off literal values in module runtime files instead of file-level constants when the value is used once and naming does not add clarity.
  • Rule: prefer no backward compatibility in new code; avoid aliases/shims/migration layers unless explicitly requested.
  • Rule: never add regression tests for changes unless a task explicitly asks for them.

API and Service Patterns

  • Rule: in module containers, prefer service-layer throw-on-error and keep routes thin; let express-async-handler propagate thrown/rejected errors via middleware instead of route-level { error } handling.
  • Rule: in module containers, services should return raw payloads (object/array/value), not { data: ... }; route handlers should wrap service results in API response envelopes.
  • Rule: status-check services are the exception to the general throw-on-error pattern; they should catch operational errors, log them, and return [] instead of throwing.

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.

bug AGENTS.md is an instructions file published in the GitHub repository bbc/bug (43 stars, last pushed 7d ago), licensed Apache-2.0. It adds 1,284 tokens to every session, about $0.0064 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
