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: 5 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 | $0.00025 | $0.06678 |
| Opus 5 | $0.00013 | $0.03339 |
| Sonnet 5 | $0.00005 | $0.01336 |
| Haiku 4.5 | $0.00003 | $0.00668 |
Grade A, and why
add-analytics 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 9d 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 — 457 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Analytics - Google Analytics (GA4)
Communication
- Detect the user's language from the conversation (the user's own messages, anywhere in the session - not just this invocation: a bare slash command like
/bootstrapcarries no language signal by itself). If nothing in the conversation gives a signal, fall back to the OS locale (node -e "console.log(Intl.DateTimeFormat().resolvedOptions().locale)") before defaulting to English. ALWAYS reply in that language for every user-facing message: questions, progress, confirmations, summaries, errors - including any example text quoted in this skill, which is illustrative and must be translated, never sent verbatim. - Use plain, non-technical business language. Never expose internal script names (*.mjs) or jargon; describe actions in human terms.
- When generating user-facing content for the scaffolded project (UI labels, emails, copy), write it in the user's language too.
- Show progress as a short natural-language checklist (in-progress and done states).
Adds Google Analytics tracking to the current project with RGPD-compliant cookie consent. Can be called by /bootstrap or standalone on an existing project.
Step 0 - Preflight: is Analytics already configured?
First of all, invoke _check-deps analytics to detect whether GA4 is already in place:
result=$(node "${CLAUDE_SKILL_DIR}/../../scripts/check-deps.mjs" analytics)
analytics_ok=$(echo "$result" | node -e "console.log(JSON.parse(require('fs').readFileSync(0,'utf8')).analytics.ok)")
ga_id=$(echo "$result" | node -e "console.log(JSON.parse(require('fs').readFileSync(0,'utf8')).analytics.gaId || '')")
If analytics_ok = true -> re-configuration mode
GA4 is already in place (ID: $ga_id). Do NOT recreate the <GoogleAnalytics> and <CookieConsent> components, nor rewrite the layout. Show a menu:
📊 Google Analytics is already in place (ID: $ga_id)
What do you want to do?
- Switch GA property (you created a new GA4 property, or you are migrating to another Google Analytics account) - I just replace the
NEXT_PUBLIC_GA_MEASUREMENT_ID- Reinstall the cookie consent banner (if the component was deleted by accident or is broken)
- Reinstall the GoogleAnalytics component (same thing, if deleted or broken)
- Exclude admin routes / authenticated areas from tracking - so that admin and logged-in client sessions are no longer counted as discovery traffic (fixes the pollution of acquisition stats)
- Set up a regular email report - I guide you through enabling GA4 scheduled reports (you receive your statistics in your inbox every week or every month, without having to open GA4)
- Redo everything from scratch (only useful if the configuration is completely broken - first remove
NEXT_PUBLIC_GA_MEASUREMENT_IDfrom the local.envand theGoogleAnalytics.tsx/CookieConsent.tsxcomponents)- Something else - tell me what you want
What ships with it
2 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.

add-analytics is a skill published in the GitHub repository flavien-ia/hypervibe-harness (37 stars, last pushed yesterday), licensed Apache-2.0. It adds 25 tokens to every session and 6,678 once invoked, about $0.0001 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.
