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 | $0.00029 | $0.00825 |
| Opus 5 | $0.00015 | $0.00413 |
| Sonnet 5 | $0.00006 | $0.00165 |
| Haiku 4.5 | $0.00003 | $0.00082 |
Grade A, and why
snr-web scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Web Presence Audit
Audit the public surface of: $ARGUMENTS
Load web-presence-audit. Load accessibility-audit for the a11y pass and
privacy-compliance for the cookie and legal-page pass.
Only assess a site the user owns or is authorised to assess.
Run the live check first
skills/web-presence-audit/scripts/web-check.sh <url>
(or web-check.ps1 on Windows). It is read-only — a handful of GET and HEAD
requests, no crawling. It covers the crawlable, legible, structured and trust
layers automatically. Then confirm by hand and go deeper.
The four layers
1 CRAWLABLE robots.txt · sitemap · REAL 404 status · canonicals · HTTPS
· one hostname · render-without-JS · no index bloat
2 LEGIBLE unique title AND description PER PAGE · canonical · Open Graph
with an absolute-URL 1200x630 image · alt text · one h1 · lang
3 STRUCTURED Organization · WebSite · LocalBusiness (if physical/service area)
· FAQPage · BreadcrumbList · Article/Product — all validated
4 TRUSTED custom 404 · FAQ page · case studies · thank-you page ·
response-time commitment · sticky mobile CTA · internal links ·
about/team · pricing · privacy · terms · cookies · deletion path
The two failures that silently destroy traffic
A soft 404 — a missing page returning 200. Every mistyped URL becomes an
indexable thin page.
curl -o /dev/null -sS -w '%{http_code}\n' https://site.com/definitely-not-real-xyz
A staging robots.txt in production — Disallow: / removes the site from
search, and nobody notices for weeks.
curl -sS https://site.com/robots.txt | grep -E '^\s*Disallow:\s*/\s*$'
Also check: does any page canonical to the homepage? That de-indexes everything but one page, and it is invisible unless you check per page.
Report per page, with the replacement text
A finding that says "write a meta description" is half a finding. One that supplies the description is a completed task.
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.

snr-web is a command published in the GitHub repository Kin9Zeus/senior-engineer-skills (3 stars, last pushed 16d ago), licensed MIT. It adds 29 tokens to every session and 825 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Pre-release gate — run the full gate, responsive + render checks, then produce the release checklist (README badge/current/changelog). Use before tagging a release.
