speckit-bug-fix

speckit-bug-fix is a skill for Claude Code from arrrrny/zuraffa. It costs 20 tokens per session (2,401 once invoked), scanned A, original, MIT.

A bug-remediation step that applies an existing bug assessment and records the resulting changes in a fix report.

In plain words
What is it for?
Use it after a bug assessment exists, optionally isolating the work on a branch or separate worktree.
Why use it?
It ensures a fix follows an already documented diagnosis and leaves a record of what was changed.

Skill for Claude Code

Written for Claude Code: $ARGUMENTS substitution. Also seen: installed under .agents/ (shared by several agents).

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is - **TDD artifacts**: ./tdd/test-list.md, ./tdd/cycle-log.md, ./tdd/verification.md (present only when the fix ran in TDD mode).

Good fit Use it after a bug assessment exists, optionally isolating the work on a branch or separate worktree.

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

speckit-bug-fix 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fix Bug

Apply the remediation that was proposed by /speckit-bug-assess and record the changes in a fix report at .specify/bugs/<slug>/fix.md. This command is only valid after an assessment exists for the given slug. Pass --branch (or --worktree) to isolate the fix on its own git branch before editing, mirroring how /speckit-specify isolates feature work.

User Input

$ARGUMENTS

The user input should identify the bug to fix. Accept any of:

  • slug=<bug-slug> or --slug <bug-slug> or just a bare slug-like token.
  • A path that contains the slug (e.g. .specify/bugs/login-timeout/).
  • Branch isolation (optional): branch / --branch creates a fix branch (<prefix>/<slug>) first; worktree / --worktree creates a git worktree instead. See Optional — isolate the fix on a branch below.
  • Nothing — fall back to context (see below).

Slug Resolution

Resolve BUG_SLUG in this order, stopping at the first match:

  1. Explicit user input — a slug passed in $ARGUMENTS (any of the forms above).
  2. Conversation context — if the current session has just run /speckit-bug-assess, the slug it reported is the working slug. Reuse it without re-prompting. Confirm it by checking that .specify/bugs/<slug>/assessment.md exists; if it does not, fall through.
  3. Single candidate on disk — list .specify/bugs/*/assessment.md. If exactly one matching assessment.md is found, use the slug from its parent directory.
  4. Disambiguate:
    • Interactive mode: ask the user which bug to fix and list the candidates.
    • Automated mode: stop with an error listing the candidates. Do not guess.

Once resolved, set BUG_SLUG and BUG_DIR = .specify/bugs/<BUG_SLUG>, and briefly state in your reply which resolution path was used (explicit / from context / single candidate / asked).

Prerequisites

  • BUG_DIR/assessment.md MUST exist. If it does not, stop and instruct the user to run /speckit-bug-assess first.
  • If BUG_DIR/fix.md already exists, ask the user whether to overwrite it before continuing (interactive mode) or refuse (automated mode).
  • Read BUG_DIR/assessment.md in full. Treat its Proposed Remediation, Files likely to change, Tests to add or update, and Risks & Considerations sections as the contract for this command.

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.
