# Agentic SEO Skill Foundation

> Use when porting deterministic SEO/AEO/GEO audit machinery — SSRF-safe fetchers, robots/llms.txt evaluation, JSON-LD schema validation and generation, snippet-format scanning, E-E-A-T/freshness/citation content scoring, GSC decay/striking-distance tracking, AI-crawler policy matrices, authenticated GitHub repository-trust audits (provider fallback, rate-limit-aware retries, release/file-inventory scoring), the standalone-script runtime plane (non-raising fetch envelope, stdlib dotenv ladder, CLI output contract), or the orchestration pattern of an 88-script evidence layer under an LLM-first router.

# Agentic-SEO-Skill: LLM-first SEO audit evidence-collector foundation

## Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is
historical, revision-pinned evidence rather than timeless guidance. Current
project source, tests, requirements, and runtime behavior outrank this
projection and decide what ships.

## Provenance and revision

- Source record: `agentic-seo-skill`; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
- Recorded revision: `main@69199160e18372bc5cdf9ddec20ccb9fb1b509f1`.
- Full provenance, coverage caveats, boundaries, and preserved evidence:
  `references/index.md`.

## Topic map

- Representative topics: Transport kernel; Parsing kernel; Crawl policy;
  Report gate; AI measurement; Schema plane; Content intelligence; Rank
  tracking.
- Scope and retrieval questions: `references/index.md#use-this-for`.
- Complete capsule chooser: `references/index.md#load-the-matching-source-dump`.
- Detailed grouped map: `references/index.md#capsule-map`.
- Source limitations and portability boundaries: `references/index.md#boundaries`.

## Retrieval

Open the index, choose one capsule matching the active question, and load only
that capsule. Revalidate its cited source and revision before relying on it. Do
not bulk-load the inventory, treat historical claims as current truth, or apply
this foundation as a procedure.
