openspec-apply-change

Use this for OpenSpec's /opsx:apply workflow.

Hermes operating rules for OpenSpec

• Work from the user's project root. If unknown, inspect the current directory first.
• Ensure the OpenSpec CLI exists before using it: openspec --version. If missing, install with npm install -g @fission-ai/openspec@latest.
• Initialize projects with openspec init --tools none unless the user also wants other AI-tool integrations. Hermes uses these skills, not OpenSpec-generated slash commands.
• Prefer agent-compatible OpenSpec CLI calls with --json where available: openspec list --json, openspec status --change <id> --json, openspec instructions <artifact> --change <id> --json, openspec validate --all --json.
• Read generated artifacts before editing or implementing. Do not invent OpenSpec state.
• Run validation after changing OpenSpec artifacts: openspec validate <change> or openspec validate --all.
• Keep changes focused. If user scope diverges, update the existing change only when intent is the same; otherwise create a new change.

Procedure

1. Identify the change.
2. Confirm planning is ready with openspec status --change <name> --json and openspec instructions apply --change <name> --json.
3. Read proposal, change specs, design if present, and tasks.
4. Implement tasks one by one.
5. After each completed task, update tasks.md checkbox from [ ] to [x].
6. Run relevant project tests or validation commands.
7. Run openspec validate <name>.
8. Report implemented tasks, files changed, commands run, and remaining tasks if any.

Do not mark tasks complete until the code has actually been changed and exercised.
