+# Creating Skills
+
+Use this skill when you need to add or revise an opencode skill under `skills/`.
+
+## Skills vs OpenAI/Codex Source Model
+
+- Treat this repo as **opencode-native**.
+- Do **not** use OpenAI/Codex-specific artifacts such as `agents/openai.yaml`, `init_skill.py`, `quick_validate.py`, or `scripts/references/assets` conventions from the old source model.
+- A skill is discovered from `skills/*/SKILL.md` only.
+
+## Required Structure
+
+1. Create a folder at `skills/<skill-name>/`.
+2. Add `skills/<skill-name>/SKILL.md`.
+3. Keep `<skill-name>` equal to frontmatter `name`.
+
+Frontmatter must contain only:
+
+```yaml
+---
+name: <skill-name>
+description: <what it does and when to load>
+permalink: opencode-config/skills/<skill-name>/skill
+---
+```
+
+## Naming Rules
+
+- Use lowercase kebab-case.
+- Keep names short and action-oriented.
+- Match folder name and `name` exactly.
+
+## Body Writing Rules
+
+- Write concise, imperative instructions.
+- Lead with when to load and the core workflow.
+- Prefer short checklists over long prose.
+- Include only repo-relevant guidance.
+
+## Companion Notes (`*.md` in skill folder)
+
+Add companion markdown files only when detail would bloat `SKILL.md` (examples, deep procedures, edge-case references).
+
+- Keep `SKILL.md` as the operational entrypoint.
+- Link companion files directly from `SKILL.md` with clear “when to read” guidance.
+- Do not create extra docs by default.
+
+## Practical Workflow (Create or Update)
+
+1. Inspect 2–3 nearby skills for local style and brevity.
+2. Pick/update `<skill-name>` and folder path under `skills/`.
+3. Write or revise `SKILL.md` frontmatter (`name`, `description`, `permalink` only).
+4. Draft concise body sections: purpose, load conditions, workflow, red flags/checks.
+5. Add minimal companion `.md` files only if needed; link them from `SKILL.md`.
+6. Verify discovery path and naming consistency:
+   - file exists at `skills/<name>/SKILL.md`
+   - folder name == frontmatter `name`
+   - no OpenAI/Codex-only artifacts introduced
