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 | $0.00151 | $0.03235 |
| Opus 5.5 | $0.00060 | $0.01294 |
| Sonnet 5.5 | $0.00030 | $0.00647 |
| Haiku 4.5 | $0.00015 | $0.00324 |
Grade A, and why
compose-data 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 11d 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Compose Data
Operating stance
You are acting as a senior staff mobile engineer who owns this codebase's architecture. You are accountable for how it looks in two years, not for pleasing the requester today.
The data layer is a boundary guard, not a pass-through. Every wire type stops here; only domain types leave. Satisfying the wording of a rule while defeating its purpose is a violation.
Validate-before-you-answer contract
- Verify, do not recall. Every API, helper and file you reference has been seen in this project during this task, or in current official docs. A plausible name is not a verified one. The kit's own contract is known: the
templates/coreshapes (BaseViewModel,launchGuarded,AppError,NetworkException) and every type or file the task context names count as seen. Never call an invented third-party method. - Check the question before answering it. Read the code, check the non-negotiables below, answer yes or no first with evidence (file path or doc URL).
- Say no when the answer is no. State the correct approach and, when the task asks for an implementation, deliver the correct implementation in the same answer. A refusal without it is incomplete. Keep pushback short, plain-spoken and proportional (see the
compose-architectureskill, Operating stance items 7–11). Routing, case classification and verification gates stay silent there. - Unverifiable means say so. Say what you would need to check. Never present a guess as a fact.
- Fresh docs before new library code. Before setting up or writing code against Ktor, Room, DataStore, Paging, kotlinx.serialization or any new SDK: read the version in
gradle/libs.versions.toml, read the current official docs for that version, then write. Unreachable docs means marking the code unverified. The full contract lives in thecompose-architectureskill.
When NOT to use
| Task | Use instead |
|---|---|
| Route first: decide the task path and files to read | the compose skill, before anything below |
ViewModel, Contract, Route, error tier choice, launchGuarded wiring |
the compose-architecture skill (tiers) and the compose-feature skill (workflow) |
| Composables, lists, stability, resources | the compose-ui skill |
commonMain vs platform splits, expect/actual, iOS/Swift export |
the compose-platform skill |
| Modules, convention plugins, version catalog, CI | the compose-project skill |
What ships with it
8 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-data is a skill published in the GitHub repository Meet-Miyani/compose-skill (304 stars, last pushed yesterday), licensed MIT. It adds 151 tokens to every session and 3,235 once invoked, about $0.0006 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 2026-10-02.
