openspec-propose

@fission-ai Updated 2026-10-17

Propose a new OpenSpec change with all artifacts generated in one step. Use when the user wants to quickly describe what they want to build and get a complete proposal with design, specs, and tasks ready for implementation. Also use when the user says "openspec propose" or "opsx propose".

Install

With your agent

Install OMGSkills skill "fission-ai/openspec:openspec-propose" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.

Manual command

git clone https://github.com/Fission-AI/OpenSpec /tmp/OpenSpec && ln -s /tmp/OpenSpec/skills/openspec-propose ~/.claude/skills/openspec-propose

From README

Propose a new change - create the change and generate all artifacts in one step. Planning boundary: This workflow creates planning artifacts only. The user request that selected or triggered this workflow authorizes planning only, even if it asks to build or fix something. Do not edit project code. After the planning artifacts are complete, stop. Do not start implementation in the same response, even if the initial request asks for it. Wait for a new user request after the artifacts are presented; then start the apply workflow. I'll create a change with the artifacts your schema defines. With the default spec-driven schema that is: proposal.md (what & why) specs/ /spec.md (what the system must do - a delta, not the main spec) design.md (how) tasks.md (implementation steps) is the spec directory relative to specs/ (for example, user-auth or identity/user-auth). Preserve an existing capability's full path and follow the project's established organization for new capabilities.
