A setup and diagnosis tool for Kotlin Multiplatform and Compose Multiplatform projects, which share Kotlin code across platforms such as Android and iOS.

Preparing or repairing Android and iOS build environments, Android emulators, JDK 17, Xcode-related tools, CocoaPods, XcodeGen, Node, and Appium or Maestro testing tools.

It checks whether the computer has the required SDKs, compilers, device tools, and project setup, then offers to install missing parts.

Token cost

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	$0.00287	$0.02159

Security

Grade D, and why

cmp-doctor scanned grade D with 3 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 6d 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.

The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.

cmp-doctor — bootstrap the CMP toolchain & diagnose the project

Your job: get the machine to a state where a CMP/KMP project can build (Android, and iOS on macOS) and run device tests — and, when run inside a project, get the project to a buildable state too. (The stamped E2E harness is Maestro — curl -fsSL https://get.maestro.mobile.dev | bash; the Appium drivers below serve the legacy pre-Maestro path.) You wrap the engine's bootstrap (src/doctor.mjs per CONTRACT/DESIGN; exposed on the CLI as the doctor subcommand). Do not hand-roll installs in bash when the engine can do it — the engine is idempotent and verifies each tool. Use this skill to drive it and to relay its consent prompts.

What it checks, then offers to install

JDK 17 (Temurin, via Homebrew or SDKMAN).
Android SDK + cmdline-tools via sdkmanager (platform, build-tools, platform-tools, emulator, a system image) and a bootable AVD.
Xcode + Command Line Tools — checks xcode-select. Xcode itself cannot be installed from the CLI; the App Store step is surfaced as the one unavoidable manual action and handled gracefully.
CocoaPods and XcodeGen (Homebrew).
Node + Appium 3.x and its drivers (appium driver install uiautomator2, and xcuitest on macOS), each verified — legacy e2e path only; Maestro is a separate one-line install.
adb / emulator reverse-port wiring for the test harness.

On Linux, it scopes to Android-only and says so explicitly (no iOS toolchain).

Project diagnosis — works on ANY KMP project

When doctor runs inside (or is pointed at, via --target-dir) a directory with Gradle files, it adds a project diagnosis section on top of the toolchain checks. This works on any KMP project with a gradle/libs.versions.toml — whoever scaffolded it:

kotlin ↔ ksp lockstep — ksp must be <kotlin>-<kspVersion>; a mismatch is the classic KMP build-killer and is reported as a FAIL.
Drift vs the nearest proven-green version set — which catalog versions differ from a CI-verified set, with create-cmp upgrade as the one-command fix.
The KSP2/iOS catch-22 — Room + an iOS target without ksp.useKSP2=true in gradle.properties dies at link time with ClassNotFoundException: …MainKt; doctor flags it (and --fix heals it).
local.properties / sdk.dir — missing file, missing key, or a path that doesn't exist.
Environment — ~/.konan size (reported when over 10 GB) and free disk space (warned under 3 GB — a real KMP build-killer).

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.

cmp-doctor is a skill published in the GitHub repository kvdm-co-pilot/create-cmp (0 stars, last pushed yesterday), licensed MIT. It adds 287 tokens to every session and 2,159 once invoked, about $0.0014 per session on Opus 5. A static security scan graded it D with 3 findings (downloads and executes remote code, reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
