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 | $0.00104 | $0.03990 |
| Opus 5 | $0.00052 | $0.01995 |
| Sonnet 5 | $0.00021 | $0.00798 |
| Haiku 4.5 | $0.00010 | $0.00399 |
Grade A, and why
studio-breakdown 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.
studio-breakdown
Reads a project's script and produces two things the AI-filmmaker loop needs before generation:
- A shot board — one
Cellper shot, with shot type, camera, a one-line action, OTIO scene/shot ids, a first-draft prompt, and a duration. - Shot tags written back into
script.fountain(narrative projects) — so the script line and the shot it produced are linkable as the same object, seen twice. - An asset checklist — the distinct characters, locations, props, and the overall style/look, each created as an
Anchorready to be seed-locked and generated.
It is the "paste a script → get a populated board + asset checklist" step. It does not generate video or images and never spends — generation is a separate, human-approved step (the supervised loop). Extraction fidelity is the whole job.
Two branches, decided by the board — not by you. Run storyboard.list_cells first:
- Empty board → scaffold. The full procedure below: segment, extract anchors, tag.
- Board already has cells → retag only. Create, delete and reorder nothing; match the
existing cells to the script's paragraphs and write only the
[[tag]]s. Jump to step 4 — steps 2 and 3 do not apply.
If you were asked only to "tag this script" (from the Studio Breakdown pane, or after
breakdown.run returned ambiguous-needs-chi), you are in the retag branch. Go to step 4.
Preconditions
- A Studio project is open (via the
com.ikenga.studioMCP:project.open/project.create). - A script exists: either a
narrativeproject with ascript.fountain(read viastoryboard.read_fountain), or a script passed in as text.
Procedure
Work against the mcp__studio__* tool surface. All calls are project-scoped (the active project is injected).
1 — Read the script
- Narrative project:
storyboard.read_fountain→ the parsed beats/scenes. - Otherwise: take the provided script text.
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-breakdown is a skill published in the GitHub repository ikenga-hq/ikenga-pkgs (0 stars, last pushed 2d ago), licensed Apache-2.0. It adds 104 tokens to every session and 3,990 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 2026-08-31.
