SkillSpector: 1 finding, 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 →
- medium Data Exfiltration · line 14 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00034 | $0.00302 |
| Opus 5.5 | $0.00014 | $0.00121 |
| Sonnet 5.5 | $0.00007 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
create-registered-user-account 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s -c /tmp/sidewalk_cookies.txt "http://localhost:9000/signUp" > /tmp/signup.html What it actually says
If you need a full registered account (e.g. to test role-based routes), do a two-step sign-up. The POST requires a CSRF token extracted from the GET response:
# Step 1: get a session + CSRF token
curl -s -c /tmp/sidewalk_cookies.txt "http://localhost:9000/signUp" > /tmp/signup.html
# Step 2: extract token and POST the form
CSRF=$(grep -o 'name="csrfToken" value="[^"]*"' /tmp/signup.html | head -1 | sed 's/name="csrfToken" value="//;s/"//')
curl -s -b /tmp/sidewalk_cookies.txt -c /tmp/sidewalk_cookies.txt -X POST "http://localhost:9000/signUp" \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "csrfToken=${CSRF}&username=claudetest&email=claude%40test.com&password=TestPass123&passwordConfirm=TestPass123&serviceHours=NO&terms=true&returnUrl=%2F"
A 303 redirect to / (with a local-authenticator cookie) means success.
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.

create-registered-user-account is a skill published in the GitHub repository ProjectSidewalk/SidewalkWebpage (111 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 302 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls).

Adversarial design critique of the current work. Render it, look at it, and argue for rejection. Run after the gates are green, never instead of them.
design-qa
Set up or run design QA gates for token + hardcoded-value lint, automated a11y (axe), contrast, visual regression across variants/states/themes/RTL, and the manual a11y checklist. Use when the user wants CI quality gates, to prevent design regressions, or to QA a component/screen before shipping.
gate
Run the one-command quality gate and report the real N/N result. Use before claiming any build/review is done.
ship
Pre-release gate. Run the full gate, responsive + render checks, then produce the release checklist (README badge/current/changelog). Use before tagging a release.
