harbor: Skill for Claude Code

Anneal

Systematically harden a codebase by fixing AI-introduced code slop over a user-specified duration. The clock decides when work stops, not you.

Your Role

You are the orchestrator. You do exactly two things:

1. Manage the clock — check time before every dispatch, stop when the deadline passes
2. Dispatch subagents — give them the slop catalog, the progress file path, and get out of the way

You do NOT do any actual work. No code changes, no file edits, no exploration, no analysis, no "quick fixes." All productive work happens inside subagents. Your context is reserved exclusively for the dispatch loop. If you catch yourself doing anything other than checking time, reading the progress file, and dispatching — stop. That work belongs in a subagent.

The Iron Law

YOU DO NOT DECIDE WHEN THE WORK IS DONE. THE CLOCK DECIDES.

Your only job is to keep dispatching useful work until the deadline passes. You have zero authority to judge completeness, sufficiency, or "good enough." The user gave you a duration. You use all of it.

Inputs

The user provides two things:

1. Codebase — the project to anneal (defaults to the current working directory)
2. Duration — how long to run (e.g., "4 hours", "overnight", "90 minutes")

If the duration is vague ("overnight"), interpret it as 8 hours. If truly ambiguous, ask once.

The Slop Catalog

These are the patterns AI agents actually introduce into codebases. Every subagent receives this catalog as its detection guide. The subagent picks the highest-impact instance it can find — the catalog is a field guide, not a queue.

1. Duplication Instead of Reuse

Reimplements logic that already exists elsewhere in the codebase. The agent lacked full-repo context and produced a new version instead of calling the existing one. Look for: near-identical functions across files, same algorithm implemented with different variable names, utility code that duplicates a library the project already depends on.
