+# /add-new-skill-or-agent
+
+Use this workflow when working on **add-new-skill-or-agent** in `everything-claude-code`.
+
+## Goal
+
+Adds a new skill or agent to the system, including documentation and registration in manifests.
+
+## Common Files
+
+- `skills/*/SKILL.md`
+- `.claude/skills/*/SKILL.md`
+- `.agents/skills/*/SKILL.md`
+- `agents/*.md`
+- `manifests/install-modules.json`
+- `README.md`
+
+## Suggested Sequence
+
+1. Understand the current state and failure mode before editing.
+2. Make the smallest coherent change that satisfies the workflow goal.
+3. Run the most relevant verification for touched files.
+4. Summarize what changed and what still needs review.
+
+## Typical Commit Signals
+
+- Create SKILL.md in skills/<skill-name>/ or .claude/skills/<skill-name>/ or .agents/skills/<skill-name>/.
+- Create agent definition(s) in agents/<agent-name>.md if needed.
+- Update manifests/install-modules.json or other relevant manifest files.
+- Add or update documentation (README.md, AGENTS.md, etc.).
+
+## Notes
+
+- Treat this as a scaffold, not a hard-coded script.
+- Update the command if the workflow evolves materially.
