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.

SkillSpector: 13 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00113 | $0.03767 |
| Opus 5.5 | $0.00045 | $0.01507 |
| Sonnet 5.5 | $0.00023 | $0.00753 |
| Haiku 4.5 | $0.00011 | $0.00377 |
Grade A, and why
Hub-and-Spoke-Discovery-and-Recovery 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 2mo 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 — 371 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hub & Spoke Discovery & Recovery
Overview
Hub & Spoke is the content architecture — one hub owns a topic cluster; spokes answer sub-intents and link up. Cornerstone is the quality bar for those pages (depth, intent, linking, fan-out, citability). This playbook is the Discovery & Recovery path for sites where reality does not match intent.
It evolves the discovery-first audit pattern: triangulate first-party signals (GSC impressions + GA4 business value) with DataForSEO organic architecture and page inventory, then audit and plan recovery without assuming which pages are hubs today.
Not this playbook: Top-down health check when cornerstones are already known → Cornerstone Content Audit.
Packaging: Tier B playbook per write-a-skill — orchestrates children; triangulation rules in REFERENCE.md.

Read each linked SKILL.md before calling it. Follow its workflow exactly. Do not re-implement child scoring inline.
Input policy
Collect from the user:
- Domain — required
- Scope —
discovery-only(Phases 1–2) orfull audit(Phases 1–6) - First-party data — at least one of:
- GSC page×query export (CSV) or GSC MCP when available
- GA4 landing-page export (CSV) or GA4 MCP when available
- Conversion events — 1–3 GA4 key event names when GA4 is provided and analysis mode is
discovery_plus_conversions - Analysis mode —
discovery_onlyordiscovery_plus_conversions(ask once; see analytics skill Step 0.5)
What ships with it
4 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.
