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 | $0.00030 | $0.00295 |
| Opus 5.5 | $0.00012 | $0.00118 |
| Sonnet 5.5 | $0.00006 | $0.00059 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
studio-tutorial-archetype 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.
What it actually says
Tutorial archetype
Built-in archetype tutorial for com.ikenga.studio. Its definition lives in archetype.json (validated against ArchetypeSchema from @ikenga/studio-schema); the MCP archetype.* namespace discovers it via the catalog loader.
What it builds
Step-by-step how-to — question hook → clarify → demo → feature-list → CTA. Longest default runtime.
Owned blocks
This skill ships: none owned under blocks/. The block catalog aggregates these with every other installed archetype skill + studio-core-blocks, so block.list sees them all regardless of which skill owns them.
Chain
The default block chain is in archetype.json → chain[]. archetype.instantiate_into_project walks the chain, instantiates each block_id with its bindings, and writes the resulting cells into the project's storyboard.json.
Notes
FAB narration arc. Longer runtime (120s default); chapters map to clarify/demo beats.
Usage
studio-init # pick this archetype at bootstrap
archetype.instantiate_into_project --archetype tutorial --project <slug>
What ships with it
1 file 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.

studio-tutorial-archetype is a skill published in the GitHub repository ikenga-hq/ikenga-pkgs (0 stars, last pushed yesterday), licensed Apache-2.0. It adds 30 tokens to every session and 295 once invoked, about $0.0001 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 2026-08-31.
