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.

Skills for this plugin. Each skill lives in its own subdirectory:
skills/
<skill-name>/
SKILL.md # required — frontmatter + skill body
META.md # required — provenance and audit fields
references/ # optional — on-demand reference docs
scripts/ # optional — executable helper scripts
assets/ # optional — templates, data files, lookup tables
Shared — both Claude Code and GitHub Copilot CLI read skills/<name>/SKILL.md.
To create or improve a skill, run /skill-author in a Claude Code session. To review a skill
without modifying it, run /skill-audit. Do not write SKILL.md by hand without following the
authoring standard — trigger descriptions and body discipline are required.
