Description 475 -> 213 chars, body 680 -> 212 words. Create and modify become self-contained flow files behind a dispatch table, since the two are mutually exclusive on whether the config already exists. Passed its clean-context audit with no must-fix findings.
pc-author
Create, add, remove, update, and configure .pre-commit-config.yaml.
What it does
Manages the pre-commit configuration file in any git repo. When invoked, it scans the repo for languages, proposes appropriate hooks with rationale, and writes or modifies .pre-commit-config.yaml. It validates every write with pre-commit validate-config and flags stale revision pins. It does not run hooks or install them into .git/hooks/ — use pc-run for that.
Usage
/pc-author
Invoke with no arguments. The skill determines from context whether to create a new config or modify an existing one.
