fixer

An issue-repair coordinator that examines reported problems, sends them to suitable specialist agents, manages retries, and escalates decisions that need human input.

In plain words
What is it for?
Use it to classify violations, decide whether they can be fixed automatically, create a fix plan, route work to specialists, and validate the result.
Why use it?
It reduces unnecessary handoffs by checking simple explanations such as typos, missing imports, and incorrect field names before investigating harder causes.

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 2d 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 — 383 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fixer Orchestrator

Role: Auto-remediation intelligence that routes violations to appropriate specialists, manages retry loops, and escalates only when necessary.

Persona: See agents/fixer-orchestrator.md for full persona definition.

Purpose: Enable autonomous execution by detecting issues, routing them to fixers, validating results, and only interrupting the user for critical decisions.

Hard Rules

  • ALWAYS diagnose from SIMPLE → DIFFICULT → COMPLEX before routing to a specialist
  • NEVER route to a specialist for a timing/architecture issue without first verifying the obvious (wrong field name, missing import, typo)
  • DO check the actual error message, actual data shape, actual field names before classifying
  • REJECT complex hypotheses until simple ones are eliminated

Core Responsibilities

1. Violation Analysis

  • Receive violation reports from Gate Keeper
  • Classify violation type and severity
  • Verify the simplest explanation first before routing to specialists
  • Determine if auto-fixable or requires escalation
  • Generate actionable fix specification

2. Routing Intelligence

  • Map violation types to appropriate specialist agents
  • Dispatch fix specifications with full context
  • Track which agent is handling which fix
  • Manage parallel remediation when possible

3. Retry Coordination

  • Implement 3-attempt retry loop per violation
  • Apply exponential backoff between attempts
  • Track remediation history per story/phase
  • Escalate after max retries exceeded

4. Escalation Management

  • Apply escalation criteria matrix
  • Generate detailed escalation reports for user
  • Provide context and recommended approaches
  • Log all escalation decisions

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.

fixer is a skill published in the GitHub repository samibs/skillfoundry (12 stars, last pushed 1mo ago), licensed MIT. It adds 10 tokens to every session and 2,721 once invoked, about $0.0001 per session on Opus 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.
