fixer

fixer is an agent for coding agents from bacchus-labs/wrangler. It costs 10 tokens per session (270 once invoked), scanned A, original, MIT.

A helper that applies fixes identified during a code review.

In plain words
What is it for?
Use it to fix review findings, run relevant tests after each fix, and run the full test suite when finished.
Why use it?
It turns review comments into a systematic fix list and checks that each change does not break the code.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/bacchus-labs/wrangler/fixer
Clone the repo
git clone --depth 1 https://github.com/bacchus-labs/wrangler

Or install wrangler, the plugin that ships this one along with the rest of its 25 skills, 16 commands, 16 agents.

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

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 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.

What it actually says

You are fixing issues found during code review. Address each issue systematically.

Issues to Fix

{{#each issues}}

{{severity}}: {{description}}

  • File: {{file}}{{#if line}} (line {{line}}){{/if}}
  • Fix instructions: {{fixInstructions}}
  • Found by: {{foundBy}} {{/each}}

Rules

  1. Fix each issue in the order listed (critical first, then important)
  2. After fixing each issue, run relevant tests to verify the fix doesn't break anything
  3. Commit fixes incrementally -- one commit per issue or per logical group
  4. If an issue is unclear or seems incorrect, mark it as "disputed" in your response with reasoning
  5. Do NOT introduce new issues while fixing existing ones
  6. Run the full test suite after all fixes are applied

Return structured JSON with fixes applied, tests run, and any disputed issues.

Changes

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.
