Halo Plugin Dev

Halo Plugin Development

Work from the target plugin and fetch current Halo documentation only when the task needs a Halo-specific contract. Do not rely on API details embedded in the skill or recalled from training data.

Establish the Target

• Inspect the existing Gradle files, src/main/resources/plugin.yaml, UI package manifest and build configuration, and nearby implementations before editing.
• Determine both the Halo platform dependency and plugin.yaml spec.requires. Do not silently raise the requirement or switch the UI build format.
• Preserve an existing plugin's structure and tooling. For a new plugin, prefer the official pnpm create halo-plugin scaffold unless the user chose another starting point.

Fetch Documentation on Demand

1. Start with the plugin documentation index when the task involves Halo plugin APIs, configuration, lifecycle, UI, DevTools, security, or integration contracts.
2. Use the complete Halo documentation index only when the route is unclear or the task crosses documentation sections.
3. Fetch only the Markdown pages relevant to the current task. Do not load llms-full.txt by default.
4. For version-sensitive work, also read the plugin API changelog, then verify exact signatures and behavior against the target dependency, source, or existing callers. The target version wins over current-site docs.

If online docs are unavailable, continue from the target checkout and dependency sources when possible, and disclose what could not be verified instead of guessing.

Halo-Specific Boundaries

• Keep blocking work off reactive WebFlux paths; follow the current reactive development guide.
• Reuse Halo-provided UI components, FormKit inputs, shared utilities, and the project's installed build tooling before adding dependencies or custom equivalents.
• Use Setting YAML for ordinary plugin settings instead of creating a duplicate settings route. Use FormKit for page and modal forms, and reuse Halo list, search, modal, feedback, and permission components before native replacements; follow the current forms and page components guide.
• Use the project's generateApiClient task to generate TypeScript models and API methods from custom models and documented SpringdocRouteBuilder endpoints. Reuse Halo's axiosInstance; do not handwrite generated resource types or create a separate Axios client for /api or /apis. Follow the current API request guide.
• Treat generated API clients and built UI assets as generated files: change their inputs and use the project's generator or build task rather than editing output.
• Store passwords, tokens, API keys, and private keys in Halo Secret, never in a ConfigMap or custom-model spec. Validate user-controlled outbound destinations against SSRF and redirect risks before attaching credentials, and keep public APIs or security switches closed when configuration loading fails. Follow the current outbound HTTP guide.
• Add RoleTemplates only when non-super-admin or anonymous access is required; grant the narrowest permissions needed.

Verify

Use the project's existing Gradle and UI scripts. Run the narrowest relevant tests and checks, and verify packaging when manifest, UI output, or generated resources affect the plugin JAR. When a runnable Halo instance is available, smoke-test the changed Console, User Center, API, lifecycle, or theme integration path.
