Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.00598 |
| Opus 5.5 | $0.00023 | $0.00239 |
| Sonnet 5.5 | $0.00011 | $0.00120 |
| Haiku 4.5 | $0.00006 | $0.00060 |
Grade A, and why
technical-seo-discovery scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Technical SEO Discovery
Make valuable public pages discoverable without generating index bloat, duplicate routes, or thin programmatic content.
Workflow
- Inventory public page types, canonical hosts, authentication boundaries, rendering modes, and content quality signals.
- Trace one URL through DNS, redirects, status, response headers, HTML robots, canonical, rendered content, internal links, and sitemap membership.
- Separate crawl, index, canonicalization, rendering, quality, and ranking problems. Do not treat sitemap submission as indexing proof.
- Define an indexability policy per page type. Private, empty, duplicate, filtered, and low-quality pages should not enter discovery surfaces.
- Make public pages return stable
200responses with server-rendered primary content, self-canonicals, useful titles and descriptions, and no accidentalnoindexheader. - Build sitemap indexes or bounded sitemaps from canonical, indexable records only. Use stable URLs and meaningful modification timestamps.
- Add internal links from crawlable hubs. Keep redirect chains to one hop and use one canonical host consistently.
- Add structured data only when the visible page supports it. Never fabricate ratings, jobs, organizations, or profile claims.
- Verify with raw headers, rendered HTML, robots and sitemap fetches, schema validation, and search-console inspection. Record recrawl latency as an external dependency.
Programmatic SEO Rules
- Publish pages because they answer a distinct query, not because a database row exists.
- Do not index expired jobs, empty profiles, private posts, search results, or unlimited filter combinations.
- Paginated or faceted directories need bounded crawl paths and canonical policy.
- A large sitemap with zero indexed pages is a quality or technical signal to investigate, not a reason to create more URLs.
- Rankings require content usefulness, links, reputation, and time after technical eligibility is fixed.
Delivery Contract
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

technical-seo-discovery is a skill published in the GitHub repository divyanshu-iitian/agent-website-design-skills (4 stars, last pushed 2mo ago), licensed MIT. It adds 57 tokens to every session and 598 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
