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
- Identify the change.
- Confirm planning is ready with
openspec status --change <name> --json and openspec instructions apply --change <name> --json.
- Read proposal, change specs, design if present, and tasks.
- Implement tasks one by one.
- After each completed task, update
tasks.md checkbox from [ ] to [x].
- Run relevant project tests or validation commands.
- Run
openspec validate <name>.
- 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.
