Topo Project Bootstrap

Use this skill when the user asks to create, convert, initialize, or bootstrap a repository as a Topo Project.

Before acting, read references/topo-project-context.md for shared Topo Project vocabulary, authoritative references, and validation expectations.

Workflow

1. Identify the Project root. Prefer the repository directory that contains or should contain the root-level compose.yaml.
2. Inspect the existing repository before editing. Read compose.yaml, Dockerfiles, README files, and source files needed to understand service purpose and build arguments.
3. Refresh the current schema and authoring docs when the requested change depends on field names, allowed values, service platform rules, or project parameter behavior.
4. Make the smallest safe change that turns the repository into a valid, useful Project while preserving plain docker compose behavior.
5. Validate the result with the topo-project-lint workflow or equivalent schema validation.

Bootstrap Guidance

• Add a root-level compose.yaml only when one is missing. If one exists, preserve existing services, build contexts, images, volumes, networks, and runtime settings unless they conflict with the Project requirements.
• Add or improve a root-level x-topo block. Do not place x-topo under services.
• Choose x-topo.name from the repository or application purpose. Prefer short, stable, lowercase, hyphenated names.
• Set x-topo.description from the actual application behavior, not generic marketing language.
• Set x-topo.type only when useful. Use application for runnable examples that compose services and library for reusable Projects intended to be extended by other projects.
• Add x-topo.features only when the repository clearly requires or showcases target capabilities. Do not guess hardware requirements from weak evidence.
• Set platform: linux/arm64 on services unless the service uses Remoteproc Runtime.
• Expose configuration through x-topo.parameters only for project parameters that users should set. When parameters are passed as Docker build arguments, ensure parameter names match the keys used in services.<service>.build.args and Dockerfile ARG instructions.
• Keep default build.args values when they help the project run with plain docker compose. Use x-topo.parameters for prompt metadata and validation intent.

Reporting

Report what changed and why. Include the Project root, files edited, validation command used, validation result, and any spec-sensitive assumptions that came from current docs or schema.
