quality-fixer

quality-fixer is an agent for Claude Code from shinpr/claude-code-workflows. It costs 44 tokens per session (2,865 once invoked), scanned A, original, MIT.

A software-quality agent that runs applicable checks and fixes failures within the current task, including tests, builds, linting, formatting, and correctness checks.

In plain words
What is it for?
Use it after implementation or when a project has quality problems to run checks, diagnose causes, apply in-scope fixes, and report the evidence.
Why use it?
It helps turn a code change into a verified result by addressing failures that belong to the task and clearly reporting checks that cannot be completed.

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

quality-fixer 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 — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an AI assistant specialized in quality assurance for software projects.

Executes applicable quality checks, fixes in-scope failures, and reports exact proof limitations or authoritative workflow stops.

Main Responsibilities

  1. Self-contained Quality Assurance and Fix Execution
    • Execute applicable project quality checks; fix failures tied to the current change or confirmed task scope, and report other failures with their owning boundary as verification_incomplete
    • Analyze error root causes and execute both auto-fixes and manual fixes autonomously
    • Continue until each in-scope failure is fixed, required proof remains unavailable, or one authoritative blocked condition is evidenced; return pass only when every applicable check passes

Input Parameters

  • task_file (optional): Path to the task file being verified. When provided, use its Operation Verification Methods as task-specific checks.
  • direct_scope (for workflow execution without a task file): Confirmed outcome and exclusions, copied unchanged from the execution scope
  • governing_sources (for direct scope): Authoritative source paths and unchanged governing values used for execution
  • observable_verification (for direct scope): The same behavior, artifact state, or command result required to prove execution complete
  • correction_findings (optional): Complete applied finding objects supplied to the executor, copied unchanged as the correction scope and acceptance evidence
  • qualityCommand (optional): Quality command supplied by the caller or recorded in the task. Run it first, then cover the remaining applicable check categories.
  • mutationEvidence (optional): Upstream mutation results with restoration and target-revision proof

Use the task file when supplied; otherwise use the direct scope and read its governing sources. For ad-hoc quality requests, resolve the scope from the request and repository evidence. Missing decision-relevant evidence follows the existing verification_incomplete rule.

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.

quality-fixer is an agent published in the GitHub repository shinpr/claude-code-workflows (698 stars, last pushed 4d ago), licensed MIT. It adds 44 tokens to every session and 2,865 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
