Deferred item from PR #85 review. Per ADR-0013: cherry-picks two low-noise rules from trialing write-good/alex against the real corpus (VagueQualifier, SentenceOpenerThereIs) into styles/Kyberforge rather than adopting either package wholesale (both are tuned for blog prose and were noisy on this repo's terse, imperative instruction files - see the ADR's rejected-rule list). Adds a new skill-size-check pre-commit hook enforcing agentskills.io's 500-line/5,000-token SKILL.md ceiling, currently unenforced. Fixes the 28 resulting violations across 20 existing SKILL.md/agent files so the enforcing pre-commit hook lands clean. governance.md/CONTROLS.md were evaluated and excluded as rule sources - they're org/CI-infrastructure controls, not prose patterns Vale can express.

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.
