Skip\n for porting an existing Gradle plugin.\nlicense: Apache-2.0\nmetadata:\n author: github:@singleton11\n version: \"0.1.0\"\n---\n\n# Kotlin Toolchain Plugin Authoring\n\nLocal plugins are the official escape hatch from declarative YAML: a `jvm/amper-plugin` module shipping\ntask actions, settings, and generated sources/resources alongside your project. Code patterns to adapt are\nin [references/examples.md](references/examples.md).\n\n## When to write a plugin\n\nWrite one when you need:\n\n- A build-time step a library's workflow expects (code generation, schema compilation, resource\n transformation, version stamping).\n- Custom verification wired into the build (pre-release checks, schema validation, contract tests).\n- A build-time value published into the JAR classpath or downstream tasks — the closest analog to Gradle's\n `project.version`.\n- A named CLI command for a repeated workflow (`./kotlin do release`).\n\nDon't write one when `module.yaml` already covers it (dependencies, JDK provisioning, source layouts,\nbasic packaging), and never to reuse a Gradle plugin — the Kotlin Toolchain cannot consume them.\n\n## Layout\n\n```\nrepo-root/\n├── kotlin, kotlin.bat # wrappers (from `kotlin init`)\n├── project.yaml # registers the plugin\n├── plugins//\n│ ├── module.yaml # product: jvm/amper-plugin\n│ ├── plugin.yaml # tasks: + commands: + generated:\n│ └── src/\n│ ├── Settings.kt # @Configurable interface\n│ ├── tasks/ # one @TaskAction per file\n│ │ ├── Foo.kt\n│ │ └── FooSteps.kt # internal shared helpers (not @TaskAction)\n│ └── /\n└── /\n └── module.yaml # plugins: { : enabled: true, ... }\n```\n\nKeep at least one consumer module in the repo — it is the only way to exercise the plugin end-to-end, and\nplugins cannot be published to any public registry yet.\n\n## `project.yaml`\n\n```yaml\nmodules:\n - consumer-app\n - plugins/\n\nplugins:\n - ./plugins/\n```\n\nWithout the top-level `plugins:` block the plugin id is unresolvable from any consumer.\n\n## `module.yaml` — the plugin module\n\n```yaml\nproduct: jvm/amper-plugin # marks the module as a plugin\n\ndependencies:\n - :\n - :: runtime-only # required only at runtime\n - :: compile-only\n\npluginInfo:\n id: # what consumers write under `plugins:`\n settingsClass: # the @Configurable interface\n\nsettings:\n jvm:\n jdk:\n version: 21\n kotlin:\n languageVersion: 2.1\n```\n\n\n## `@Configurable interface Settings`\n\nDefaults go in interface property getters; nested blocks become nested `@Configurable` interfaces.\n\n```kotlin\n@Configurable\ninterface Settings {\n val someValue: String get() = \"default\"\n val checks: ChecksSettings\n}\n\n@Configurable\ninterface ChecksSettings {\n val strict: Boolean get() = true\n}\n```\n\nConsumers override what they need in `module.yaml`; omitted values fall back to the getter default:\n\n```yaml\nplugins:\n :\n enabled: true\n someValue: \"override\"\n checks:\n strict: false\n```\n\n## `@TaskAction`\n\nTask actions are top-level `fun`s, called when the matching `plugin.yaml` entry executes.\n\n```kotlin\n@TaskAction\nfun foo(\n @Input moduleRootDir: Path,\n @Output outputDir: Path,\n settings: Settings,\n) {\n // body\n}\n```\n\n- `@Input path: Path` — declared input; Kotlin Toolchain snapshots its contents for execution avoidance.\n- `@Output path: Path` — declared output directory; Kotlin Toolchain creates it and passes the path in. Write\n to the exact `Path` you received, or downstream references won't find the result.\n- `settings: Settings` (or any `@Configurable`) — typed configuration, wired in `plugin.yaml`.\n- Plain `Path` / primitives — passed literally from `plugin.yaml`.\n- `println(...)` is the output channel; Kotlin Toolchain captures stdout.\n\n### Execution avoidance\n\nA `@TaskAction` is skipped when its declared inputs are unchanged. Tasks whose real inputs are Git history,\nthe network, or environment variables cannot be fingerprinted, so opt out:\n\n```kotlin\n@TaskAction(executionAvoidance = ExecutionAvoidance.Disabled)\nfun foo(@Output outputDir: Path, settings: Settings) { /* ... */ }\n```\n\nTasks with no `@Output` are never cached and always re-run — correct for purely side-effecting tasks\n(releases, deployments, pushes).\n\n## `plugin.yaml`\n\n```yaml\ntasks:\n foo:\n action: !\n moduleRootDir: ${module.rootDir}\n outputDir: ${taskOutputDir}\n settings: ${pluginSettings}\n\n bar:\n action: !\n input: ${tasks.foo.action.outputDir}/result.txt\n settings: ${pluginSettings}\n\ngenerated:\n resources:\n - directory: ${tasks.foo.action.outputDir}\n\ncommands:\n - foo\n```\n\n| Reference | Resolves to |\n|---|---|\n| `${module.rootDir}` | Directory containing the consumer's `module.yaml`. Pass as `@Input` to inspect the consumer's tree. |\n| `${taskOutputDir}` | Toolchain-managed per-task output directory. Pass as `@Output`. |\n| `${pluginSettings}` | The `@Configurable` object built from the consumer's `module.yaml`. |\n| `${tasks..action.}` | Another task's parameter — used in `generated.*` and to wire one task's `@Input` to another's `@Output`. |\n\n### `generated.resources` / `generated.sources`\n\nBoth register a directory (usually a task's `@Output`) as a contribution to the consumer's build, and both\nauto-wire the producing task to run first:\n\n- `generated.resources` — added to the JAR classpath, reachable via `getResourceAsStream(\"/path/in/jar\")`.\n- `generated.sources` — added as a Kotlin source root and compiled with the consumer's `src/`.\n\n### Tasks vs commands\n\nTasks are the implementation, addressed as `./kotlin task ::@` — the docs advise\nagainst relying on that mangled name. Commands are the public API: `./kotlin do `, listed via\n`./kotlin show commands` (`-m ` to scope).\n\n- A task whose `@Output` feeds `generated.resources`/`generated.sources` is a build-graph contributor. Keep\n it out of `commands:`; it runs automatically and exposing it invites users to run it by hand.\n- A task users invoke directly must be in `commands:`.\n\n## File-based task communication\n\nThere is no shared mutable build state — no `project.version`, no extension property maps. Tasks talk\nthrough matched paths:\n\n1. The producer takes `@Output outputDir: Path` and writes files into it.\n2. `plugin.yaml` points a consumer task's `@Input` at `${tasks..action.outputDir}/`.\n3. The Toolchain infers the dependency from the path match — no `dependsOn` API needed.\n\nThe same `@Output` directory can serve build-time consumers (via `@Input`) and runtime consumers\n(registered under `generated.resources`, read via `getResourceAsStream`) simultaneously.\n\n## Runtime overrides via environment variables\n\nThere is no `-Pkey=value`. Read env vars inside the action for ephemeral overrides:\n\n```kotlin\nval forced = System.getenv(\"MYPLUGIN_FORCE_VALUE\")?.takeIf { it.isNotBlank() }\nval skipChecks = System.getenv(\"MYPLUGIN_SKIP_CHECKS\")?.equals(\"true\", ignoreCase = true) == true\n```\n\nPass the env map in as a constructor parameter rather than calling `System.getenv()` deep in the call stack,\nso logic stays unit-testable. Document every recognised variable in the plugin's README. Env vars are\nephemeral overrides, not a trust boundary — validate a value before using it in a file path or process\nargument.\n\n## Sharing logic across task actions\n\nTasks often share steps (verify → create → push). Don't compose an atomic user-facing task from a chain of\nbuild-graph tasks: separate invocations re-open shared resources and open a window where another process\nobserves intermediate state.\n\n## Limitations to design around\n\n- Plugins are local-only; no public registry publishing yet.\n- Plugins are module-level; there is no project-wide plugin. Every consumer module lists it under\n `plugins:`, and cross-module effects flow through files.\n- No `${...}` interpolation in `module.yaml` (as of 0.11) — consumer settings are literal values.\n- No `Project.afterEvaluate`, no lazy `Provider`/`Property` graph. Compute derived values in the action body.\n- `-h`/`--help` does not list plugin commands; use `./kotlin show commands`.\n\n## Validate against a consumer\n\n1. Add a small consumer module (`demo-app/`, `sample/`) enabling the plugin with realistic settings.\n2. Have its `main.kt` or a test read whatever the plugin publishes.\n3. Put the exact commands and expected output in the plugin's README, so a fresh clone can paste and compare.\n\nPlugin docs: \n","tagline":"Load when authoring, writing, or designing a Kotlin Toolchain local plugin to extend the declarative build with code generation, build-time processing, custom verification, or packaging that module.yaml cannot express, or when referencing @TaskAction, @Configurable, plugin.yaml, ","category":"design-creative","tags":["agent-skill"],"author":"github:@singleton11","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"recursive skill source sync","sourceDetail":"Kotlin/kotlin-agent-skills","creatorName":"github:@singleton11","creatorUrl":"https://github.com/Kotlin","sourceUrl":"https://github.com/Kotlin/kotlin-agent-skills/tree/main/skills/kotlin-tooling-kotlin-toolchain-plugin-authoring","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/kotlin-kotlin-tooling-kotlin-toolchain-plugin-authoring#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
