Excerpt

OSpec Router

Use this root skill as a compact router. Keep invariant safety and workflow-selection rules here; load detailed commands and stage protocols from the initialized project's indexed files only when that stage is active.

Default Entry

When the user asks to initialize a project, run ospec init [path]. In AI-assisted initialization, pass the explicit or conversational language with --document-language. If useful context is missing, ask once for a short project summary or tech stack; if the user skips it, continue with placeholders. Verify the generated files on disk and stop before creating work unless the user explicitly asks for a change or goal.

This is the opening of the README. Read the full README on GitHub.

Frequently asked about OSpec

What else does clawplays publish alongside OSpec?
OSpec is one of 3 skills that DirSkills catalogs from clawplays/ospec, the repository it ships in. Its siblings there include OSpec Change and OSpec Goal. Each one is a separate skill with its own page in this directory, installs the same way OSpec does, and is maintained by clawplays in that same repository. The rest of the collection is listed on the clawplays/ospec page.
How does OSpec compare to other AI Engineering skills?
OSpec ranks #2198 by stars among the 2451 AI Engineering skills in this catalog. The most-starred ones next to it are Architecture Decision Records, AI-First Engineering and Agentic OS. DirSkills ranks by the star count of the repository each skill ships in, so that order reflects how popular those repositories are rather than any review of OSpec against them.
