bug

A command for reproducing and fixing a ready-to-work software bug with tests, then opening a pull request. For web bugs, it first checks the problem in a browser.

In plain words
What is it for?
Use it when you have a GitHub bug issue and want a new branch, a test-driven fix, and a reviewable pull request without merging it.
Why use it?
It turns a reported problem into a verified code change and records evidence about the fix before review.

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 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 2d 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.

What it actually says

Read lanes/bug.md and AGENTS.md. Ask Telemetry for evidence if the ticket has none. Web app bugs: /browser-use first, then /tdd. Use /mermaid when you write a PR.

At start, factory.sh mem read for this issue (or project if no issue). Write started only if that read shows no in-progress bug run: factory.sh mem write --lane bug --status started --harness <claude|cursor|codex|grok> --issue . At the end, factory.sh mem write --lane bug --status done|blocked|failed --harness <claude|cursor|codex|grok> --issue --summary "" --evidence --next-steps "". Missing memory: warn once and continue.

Need a GitHub issue. New branch off main. Open a PR. Print the URL. Do not merge.

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.

bug is a command published in the GitHub repository Kripu77/software-factory (7 stars, last pushed 2d ago), licensed MIT. It adds 27 tokens to every session and 235 once invoked, about $0.0001 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 2026-08-31.
