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: 6 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 | $0.00045 | $0.01860 |
| Opus 5.5 | $0.00018 | $0.00744 |
| Sonnet 5.5 | $0.00009 | $0.00372 |
| Haiku 4.5 | $0.00005 | $0.00186 |
Grade A, and why
joycraft-collaborative-setup 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 1mo 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
At skill entry, run node docs/.joycraft/check.mjs check --json --session <session-id> once, reusing JOYCRAFT_SESSION_ID if supplied or one ID chosen for this conversation. If the checker is missing or fails, continue the requested skill quietly without retrying setup. Offer updates only for display: true; current, postponed, off, and unknown stay quiet. If automaticUpdate is present, finish this skill, then run its exact command once from the project root: the candidate must verify every safety gate before applying. Other updates require approval. After an offer or automatic attempt, record it with node docs/.joycraft/check.mjs acknowledge <available-version> --session <session-id>. Apply updates only at this workflow boundary; after success, reinvoke the skill or restart the session to load changed instructions.
Collaborative Setup
You are setting up Joycraft for a team. Solo defaults stay solo; this skill adds the team-only ceremony — docs/areas/ folders, area README/boundaries, and a thin team-facing CONTRIBUTING-joycraft doc.
This skill is interactive — ask the user, don't auto-detect.
When to run
Run once when a team is adopting Joycraft on a multi-dev project. Solo users do not need this skill — solo defaults are fine without it.
Step 1: Confirm Team Context
Ask the user:
"Setting up Joycraft for a team? (vs. solo work) If you're unsure, you can skip — solo defaults work fine and you can run this later."
If the user says "actually solo," bail before any writes:
"No problem. The solo workflow needs no extra setup. Run
$joycraft-new-featurewhen you want to start a feature."
Step 2: Check for Flat Layout — Bail if Present
Before scaffolding team structure, check the project's docs/ for per-feature artifacts. Look for any of:
docs/features/<slug>/brief.mddocs/features/<slug>/research.mddocs/features/<slug>/design.md- Loose spec subdirectories that predate the per-feature layout (specs not under
docs/features/<slug>/specs/ordocs/bugfixes/<area>/)
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.

joycraft-collaborative-setup is a skill published in the GitHub repository maksutovic/joycraft (15 stars, last pushed 25d ago), licensed MIT. It adds 45 tokens to every session and 1,860 once invoked, about $0.0002 per session on Opus 5.5. 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.
