bug-fix

bug-fix is a command for coding agents from Pimzino/claude-code-spec-workflow. It costs 0 tokens per session (792 once invoked), scanned A, original, MIT.

A command that implements the planned solution for an analyzed bug during the fix phase of a bug workflow.

In plain words
What is it for?
It reads the bug documents and project context, applies the implementation plan, handles errors, adds or updates tests when specified, and records the changes.
Why use it?
It turns the approved root-cause analysis into targeted code changes while keeping the work aligned with project conventions.

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-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 3d 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.

Bug Fix Command

Implement the fix for the analyzed bug.

Usage

/bug-fix [bug-name]

Phase Overview

Your Role: Implement the solution based on the approved analysis

This is Phase 3 of the bug fix workflow. Your goal is to implement the fix while following project conventions.

Instructions

You are working on the fix implementation phase of the bug fix workflow.

  1. Prerequisites & Context Loading

    • Ensure analysis.md exists and is approved

    Load ALL Context Once (Hierarchical Context Loading):

    # Load steering documents (if available)
    claude-code-spec-workflow get-steering-context
    

    Bug documents to read directly:

    • .claude/bugs/{bug-name}/report.md
    • .claude/bugs/{bug-name}/analysis.md
    • Understand the planned fix approach completely
  2. Implementation Process

    1. Follow the Implementation Plan

      • Execute changes exactly as outlined in analysis.md
      • Make targeted, minimal changes
      • Follow existing code patterns and conventions
    2. Code Changes

      • Implement the fix following project standards
      • Add appropriate error handling
      • Include logging or debugging aids if needed
      • Update or add tests as specified
    3. Quality Checks

      • Verify fix addresses the root cause
      • Ensure no unintended side effects
      • Follow code style and conventions
      • Run tests and checks
  3. Implementation Guidelines

    • Follow steering documents: Adhere to patterns in tech.md and conventions in structure.md
    • Make minimal changes: Fix only what's necessary
    • Preserve existing behavior: Don't break unrelated functionality
    • Use existing patterns: Leverage established code patterns and utilities
    • Add appropriate tests: Ensure the bug won't return
  4. Testing Requirements

    • Test the specific bug scenario
    • Verify related functionality still works
    • Run existing test suite if available
    • Add regression tests for this bug

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-fix is a command published in the GitHub repository Pimzino/claude-code-spec-workflow (3,855 stars, last pushed 12mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 792 tokens. 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 2026-08-30.
