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 | $0.00094 | $0.01796 |
| Opus 5 | $0.00047 | $0.00898 |
| Sonnet 5 | $0.00019 | $0.00359 |
| Haiku 4.5 | $0.00009 | $0.00180 |
Grade A, and why
add-collab 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 — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Collab - Manage GitHub collaborators
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).
You manage the GitHub collaborators of the current project.
This skill assumes the project is hosted on GitHub and deployed via Vercel. The first time it runs on a new project, it sets up GitHub Actions as the deploy mechanism (via the _setup-github-deploy helper). On subsequent runs, it skips straight to collaborator management.
Step 1 - Detect whether GitHub Actions deploy is already configured
Run two checks in parallel:
# Check 1 - workflow file exists locally
test -f .github/workflows/deploy.yml && echo "workflow:yes" || echo "workflow:no"
# Check 2 - the 3 Vercel secrets exist on GitHub
gh secret list 2>/dev/null | awk '{print $1}'
The setup is complete only if all 4 conditions are true:
.github/workflows/deploy.ymlexists locally- Secret
VERCEL_ORG_IDis listed - Secret
VERCEL_PROJECT_IDis listed - Secret
VERCEL_TOKENis listed
If any of these is missing, the setup is incomplete → invoke the _setup-github-deploy internal skill, wait for it to complete, then continue to Step 2.
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-collab is a skill published in the GitHub repository flavien-ia/hypervibe-harness (37 stars, last pushed today), licensed Apache-2.0. It adds 94 tokens to every session and 1,796 once invoked, about $0.0005 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.
