Systematic development workflow: Analyze → Plan → Execute → eLicit → eXamine. Use for ANY development task: features, bug fixes, refactoring, hotfixes. Triggers: "implement", "create", "build", "fix", "add feature", "refactor", "develop". Auto-detects project type (Laravel, Next.js, React, Swift) and loads framework-specific references. Enforces: files <100 lines, interfaces separated, SOLID principles, expert self-review, sniper validation. Modes: --auto (default), --manual, --skip-elicit
Auto-review skill for expert agents. After coding, expert applies elicitation techniques to self-correct before sniper validation. Inspired by BMAD-METHOD. Use when: an expert agent needs to self-review and self-correct code after the Execute phase, before sniper validation.
Use when marking a task as complete, finishing a feature, or claiming a bug is fixed. Ensures functional resolution is verified with evidence before closing. Do NOT use for: lint/type/code-quality validation (use code-quality / sniper AFTER functional verification passes).
Smart conventional commit with security validation, branch flow enforcement, and auto-detection. Use when committing changes, saving work, staging and committing, or choosing a conventional commit message.
Use when committing, branching, opening PRs, or deciding merge strategy. Covers GitHub Flow (default), trunk-based, branch naming conventions, squash vs rebase, branch lifecycle, and protected branch enforcement.
Universal post-commit actions. CHANGELOG update for all repos (git tag is created POST-MERGE, not here — see `commit` command Step 8). Plugin version bumping for marketplace repos. Triggered after any code commit (except wip/amend/undo).

Targets: Astro 7.
Complete SEO strategy for Astro 7 sites — zero JS by default makes Astro naturally SEO-friendly.
Before ANY implementation, spawn 3 parallel agents (Codex spawn_agent):
After implementation, run sniper for validation.
| Feature | Benefit |
|---|---|
| Zero JS by default | Pure HTML for crawlers, instant indexing |
| Static output | Sub-second TTFB, top Core Web Vitals |
Astro.site | Canonical URL construction built-in |
| Islands Architecture | Only hydrate interactive parts |
Create a reusable <SEO /> or <Head /> component accepting title, description, og, canonical props. Place in all layouts. Use Astro.site for absolute URL construction.
Always construct canonicals with Astro.site:
const canonical = new URL(Astro.url.pathname, Astro.site);
Inject JSON-LD via <script type="application/ld+json" set:html={JSON.stringify(schema)} />. Use set:html to avoid XSS — never template string interpolation.
| Topic | Reference | When to Consult |
|---|---|---|
| Meta Tags & OG | meta-tags.md | Setting up head metadata |
| JSON-LD | structured-data.md | Rich snippets, schema.org |
| Sitemap & RSS | sitemap-rss.md | Search indexing, feeds |
| Canonical & hreflang | canonical-hreflang.md | Duplicate content, i18n |
| Core Web Vitals | core-web-vitals.md | LCP, CLS, FID optimization |
| Template | When to Use |
|---|---|
| seo-head.md | Reusable SEO head component |
| json-ld.md | JSON-LD BlogPosting, WebSite schemas |
