We Searched the Agent Skills Ecosystem for SEO
Source: Dev.to
Search Process
We searched every repository we could find, starting with the official catalog and working outward:
anthropics/skills— Anthropic’s official skills listagentskills/agentskills— open standard referenceskillmatic-ai/awesome-agent-skills— community catalogPrat011/awesome-llm-skills— community catalog- Broad GitHub:
sickn33/antigravity-awesome-skills,vercel-labs/agent-skills,OneRedOak/claude-code-workflows,muratcankoylan/Agent-Skills-for-Context-Engineering
We tried every keyword we could think of: SEO, technical SEO, sitemap, robots, canonical, JSON‑LD, structured data.
Result: Zero matches. No SKILL.md files, no coverage.
Findings
The search was part of a larger audit covering six web‑ops disciplines:
| Discipline | Best Match | Gap |
|---|---|---|
| Content strategy | A general writing partner — no strategy layer | High |
| UX evaluation | A design review workflow — no formal heuristics | High |
| CSS architecture | An aesthetics guide — no layout methodology | High |
| Technical storytelling | A generic writing assistant | High |
| SEO | Nothing | High |
| Accessibility testing | One shallow checklist buried in a larger workflow | High |
All six disciplines lack adequate skill coverage. The ecosystem is heavily focused on engineering workflows, with virtually no web‑ops support. SEO was the clearest zero.
Implications
Our agents build web pages: they write HTML, scaffold components, and generate sitemaps. Without an SEO skill in the loop, pages ship without discoverability checks:
- No canonical URL validation
- No structured data
- No
robots.txtguidance - No performance baselines
A page can be valid HTML, pass accessibility checks, render correctly in every browser, and still never appear in search results. This is not caught in code review.
SEO Skill Development
Ari authored technical‑seo‑patterns — the first SEO skill in the ecosystem. It covers the technical baseline a shipping team needs:
- On‑page essentials: titles, meta descriptions, heading hierarchy, image alt text
- Canonical URL strategy: avoid duplicate‑content traps
- Robots and sitemap hygiene: ensure crawlers can reach everything published
- Structured data patterns (JSON‑LD): enable rich results
- Core Web Vitals checkpoints: prevent silent performance degradation
This is not a keyword playbook; it is the set of checks that prevent a published page from being invisible by default.
Conclusion
The SEO gap was the sharpest signal, but the broader finding is structural: the Agent Skills ecosystem was built by engineers for engineering problems. Content strategy, UX evaluation, CSS architecture, storytelling, and accessibility have no meaningful skill coverage.
We built the SEO skill because we needed it. The other five gaps remain open.
