bugfix-quick

bugfix-quick is a skill for Claude Code from nguyenthienthanh/aura-frog. It costs 47 tokens per session (995 once invoked), scanned A, original, MIT.

A workflow for fixing software bugs by first finding the underlying cause, then adding a failing test, making the fix, and running the test suite. TDD, or test-driven development, means writing a test that exposes the problem before changing the code.

In plain words
What is it for?
Use it for bug investigation, reproducing failures, writing regression tests, applying source-level fixes, and checking the complete test suite.
Why use it?
It reduces the risk of covering up a symptom and having the same bug return later.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is Human-readable explanation: see [docs/architecture/HIERARCHICAL_PLANNING.md](../../../docs/architecture/HIERARCHICAL_PLANNING.md).

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

bugfix-quick 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 1mo 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AI-consumed reference. Optimized for Claude to read during execution. Human-readable explanation: see docs/architecture/HIERARCHICAL_PLANNING.md or docs/getting-started/ depending on topic.

Quick Bugfix

For bugs only. Features/refactors → run-orchestrator.


Core Principle

NO FIXES WITHOUT ROOT CAUSE. Fix at SOURCE, not symptom.

Process (4 Steps)

Step Name Agent Statusline
S1 Investigate lead (inline) — uses Read/Grep/Bash to reproduce bugfix S1
S2 Test RED tester — writes failing test bugfix S2
S3 Fix GREEN architect / frontend / mobile (per artifact, via agent-detector) bugfix S3
S4 Verify tester — runs full suite bugfix S4

Announce per step. When transitioning, surface to the user: ─── Step S{N} · {Name} ─── Dispatching {agent}…. Also update run-state.json#current_step (one of: investigate, test-red, fix-green, verify) and #active_agent so the statusline reflects reality.

1. Investigate

  • Read error + stack trace
  • Reproduce the bug
  • git log / git diff for recent changes
  • Trace backward: where did bad data originate?
  • Context economy (rules/core/context-economy.md) — Grep for the failing symbol first, then Read with offset+limit on the matched lines only. Don't read the full file unless the bug spans it.

2. Write Failing Test (RED)

  • Test that reproduces the bug exactly
  • Pick the right layer (skills/test-writer/SKILL.md#test-type-selection). If the bug is a UI / user-flow / auth / payment regression → e2e spec via Playwright MCP, not a unit test that won't actually reproduce it. If the bug is in pure logic → unit. The test must fail for the right reason.
  • User confirms test FAILS

3. Fix (GREEN)

  • Minimal, focused change at root cause
  • User confirms test PASSES

4. Verify

  • Run full test suite — and the e2e suite if S2 wrote an e2e spec (npx playwright test / npx cypress run). No regressions in either.
  • Read output, THEN claim result. "Tests passed" with no pass count = 0 tests collected = bug.
  • Wrong: "Should work now" / Right: "Tests pass: [output]"

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.
