87 charsno explicit “when” trigger
Intermediate

Key capabilities

  • Propose a new openspec change
  • Generate all required artifacts for a change type
  • Obtain authoritative templates and rules for each artifact
  • Validate artifacts against project rules and format
  • Prepare a change for implementation

How it works

The skill guides the user through creating a new change, generating artifacts based on the chosen type, and validating them against project rules. It provides instructions and templates for each artifact.

Inputs & outputs

You give it
A change type and description (e.g., 'feat: add a greeting endpoint')
You get back
An apply-ready change with all required and validated artifacts

When to use cospec-propose

  • Plan new feature development
  • Verify implementation quality
  • Enforce integration testing
  • Structure dev process

About cospec-propose

Restricts tools by stage to force analysis, planning, and verification before and after implementation. It prevents premature coding and ensures quality throughout the lifecycle.

Propose a new change and generate every artifact its type requires, in one guided pass.

When not to use it

  • When directly calling `openspec`
  • When hand-editing bookkeeping files under `openspec/changes/`
  • When exploring the repository to learn what to write

Prerequisites

the cospec CLI (@aligned-team/cospec)

Limitations

  • Does not start implementation of the change
  • Requires adherence to specific artifact formats for machine parsing
  • Does not allow adding artifacts that the type forbids

How it compares

This workflow ensures all necessary artifacts are created and validated in a structured, guided manner, unlike a manual process that might miss required steps or introduce formatting errors.
