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 | $0.00228 | $0.04111 |
| Opus 5 | $0.00114 | $0.02056 |
| Sonnet 5 | $0.00046 | $0.00822 |
| Haiku 4.5 | $0.00023 | $0.00411 |
Grade A, and why
compose-screen-splitter 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 — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Compose Screen Splitter
Why this skill exists
Compose Screens accumulate UI sections (header, list, summary, dialog, sheet, …) until the file becomes hard to navigate, hard to review, and hard to preview. The Medium article "How to split Compose screens before they become unmanageable" names the symptoms (600-800 lines, 3-4 levels of nesting, six concerns sharing one file) and the cure (Screen↔Content split, name-driven extraction, feature-local component packages).
The NutriSport project has already adopted most of the cure as rules — Route↔Screen separation in conventions.md, :core:<name> for cross-feature reuse in architecture.md Rule 12, design-system primitives in :shared:ui/component/, Preview discipline in preview.md. What's missing is an executor: nobody is responsible for noticing when a Screen crossed the threshold and applying these rules without breaking the contract surface (DI in Routes, no DI in Screens, Preview light+dark for Screens, internal reuse never public).
This skill is that executor. It works in two modes — audit-only (read-only report) and execute (run the full split with compile + test verification).
When to invoke
Trigger phrases (English + Ukrainian, dictation-friendly):
- "split this Screen", "розпиляй цей екран", "decompose this composable file"
- "DetailsScreen is too long", "файл занадто довгий"
- "audit screen size", "перевір розмір екрана"
- "extract sections from XxxScreen", "винеси секції в окремі файли"
- After the
featurepipeline finishes and the new Screen is ≥300 lines (Phase 4 wires this in automatically — seefeature/SKILL.mdStep 19.5).
If the user mentions a *Screen.kt file in any of these contexts, invoke the skill.
What ships with it
3 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.

compose-screen-splitter is a skill published in the GitHub repository satanyakiv/NutriSport (11 stars, last pushed 3mo ago), licensed MIT. It adds 228 tokens to every session and 4,111 once invoked, about $0.0011 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.
