Quick brief

Tool: treefmt. This skill gives an agent a bounded repository-maintenance job: define one formatter plan for a mixed-language codebase and apply it consistently so generated edits stay predictable.

How it works

What this skill actually does

When to use it: invoke this before review, before sweeping refactors, or when a repository has several language-specific formatters and the agent needs one stable entry point for formatting. Using this skill is different from using the product normally because the workflow is orchestration-focused: declare the formatter set once, run it at repo scope, and hand back a clean predictable formatting pass.

Scope boundary: this is not a generic formatter listing and not a language-specific style tool card. Its boundary is narrower: coordinate multiple existing formatters from one repo-level plan with treefmt.
