Claude Skills and Agent Code Review Patterns

Stack-specific rules loaded by dh:code-reviewer when SKILL.md, agent frontmatter files, or plugin.json files are detected.

Frontmatter Validity

name must match the containing directory name exactly — mismatch causes lookup failures
name must satisfy ^[a-z][a-z0-9-]*$ — lowercase letters, digits, hyphens only
description must be a single-line string — no YAML multiline indicators (>-, |-, >, |)
tools field (in agents) must be a comma-separated string, not a YAML array — Read, Grep, Glob not [Read, Grep, Glob]
model must be one of sonnet, opus, haiku, or inherit — no version strings, no full model IDs
Run uvx skilllint@latest check --fix <path> after every frontmatter edit — auto-fixes YAML formatting issues including quoting
