p5-bugfix

p5-bugfix is a command for coding agents from jonase47/ccpr. It costs 0 tokens per session (1,479 once invoked), scanned A, original, MIT.

Systematically analyzes a found bug, identifies the root cause and fixes it with an accompanying regression test. Goal: the bug is fixed, secured by a test, and cannot be silently reintroduced.

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

p5-bugfix 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.

/p5-bugfix – Analyze & Fix Bug

Systematically analyzes a found bug, identifies the root cause and fixes it with an accompanying regression test. Goal: the bug is fixed, secured by a test, and cannot be silently reintroduced.

Argument: $ARGUMENTS = [Bug description/ticket ID]

If provided: Analyze and fix the described bug or the bug with the named ID. If not provided: resolve the bug via the work-item adoption guard below (falls back to reading SPRINT.md or the latest review/acceptance protocols and asking, if the project is still on prose). Do not make assumptions.

0. Work-item adoption guard (ADR-0002 §8)

A bug is a work item too (--type fix) — whether it was found during /p5-review//p5-acceptance (the story itself is already In Progress, sent back by the reviewing gate) or reported standalone (no existing item yet).

Run python3 ~/.claude/scripts/workitems.py list.

  • Non-empty array → the project uses the structured store. Use the CLI for all item state below:
    • No $ARGUMENTS: resolve the bug via workitems list --status "In Progress" (items sent back to dev by a review/acceptance rejection land here); if more than one, ask which to fix — do not assume.
    • $ARGUMENTS provided: resolve <id> by matching $ARGUMENTS against a story's title, or directly if it looks like a Work-Item id (WI-NNNN) from BACKLOG.md/SPRINT.md, then confirm with the user. If it matches no existing item (a standalone bug report, not yet tracked), create it first: workitems create --title "<bug summary>" --type fix --description "$ARGUMENTS" (unfiltered list duplicate-title check first — trim + casefold — so a re-run never recreates the same bug item).
  • [] and no docs/workitems/ directory → still on prose. Read SPRINT.md to find/ask which bug is next, as before. Emit one line: "Tip: run lift to adopt the structured work-item store."
  • [] but docs/workitems/ exists → adopted store, just empty right now. Treat as adopted: use the CLI, not the prose fallback.

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.
