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.

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 | $0.00043 | $0.00652 |
| Opus 5 | $0.00022 | $0.00326 |
| Sonnet 5 | $0.00009 | $0.00130 |
| Haiku 4.5 | $0.00004 | $0.00065 |
Grade A, and why
seo-audit 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 10d 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
What this measures
How well a page can be crawled, chunked, understood, and cited by AI answer
engines — not classic blue-link SEO. The audit_page tool computes this
deterministically: page data flows through context.dev, then a fixed rubric of
~30 checks scores six categories into a 0–100 total. Your job is to present
that result, not to re-score it.
The result shape
audit_page returns JSON with:
score(0–100) andband({ label, interpretation }).stats— words, headings, links, externalLinks, jsonLdBlocks, char counts.categories[]— each{ id, name, score, maxScore, naExcluded, items[] }.categories[].items[]— each check:{ id, label, status, evidence, recommendation, score, maxScore }.statusispass | partial | fail | na.topPriorities[]— the highest-impact failing/partial checks, pre-sorted.agentPrompts—{ full, topIssues[] }, ready-to-run fix prompts.diagnostics— context.dev fetch status and JSON-LD parse failures.
The six categories
| ID | Category | Max |
|---|---|---|
| A | Technical AI Crawlability | 28.4 |
| B | Content Structure & Chunking | 25.4 |
| C | Structured Data / Schema | 13.4 |
| D | E-E-A-T & Entity Authority | 21.4 |
| E | Off-site / Citation Surface Presence | 8.4 |
| F | Measurement & Governance | 3 |
Scoring (already applied by the tool): pass = full weight, partial = half,
fail = 0, na = excluded from the denominator. Bands: Critical ≤40 ·
Below average ≤55 · Average ≤70 · Strong ≤85 · Excellent >85.
Output
Report, in order:
- The overall
score/100, itsband.label, and theband.interpretation. - A per-category breakdown: for each category,
score/maxScoreand the pass/partial/fail counts. - The failing and partial checks, highest-impact first — use
topPrioritiesand the matchingitems(cite each check'sid,evidence, andrecommendation). - The agent-ready fix prompt: present
agentPrompts.fullverbatim in a copy-paste block.
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.

seo-audit is a skill published in the GitHub repository shadcn-labs/agentcn (458 stars, last pushed 17d ago), licensed MIT. It adds 43 tokens to every session and 652 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
