# Sendmux Skills Agent Guide

Build only public Sendmux agent skills in this repository.

## Rules

- Teach only public Sendmux surfaces: API endpoints, SDK packages, the `sendmux` CLI, and Sendmux MCP servers.

- Do not expose Sendmux backend, hosting, datastore, service, vendor, or implementation details.

- Verify every endpoint, command, tool, package name, and key prefix from source before writing it into a skill.

- Keep `SKILL.md` bodies under 500 lines when possible. Move detail to one-level `references/` files.

- Use only canonical skill resource directories: `references/`, `scripts/`, and `assets/`.

- Draft evals before skill bodies. Validate, benchmark, optimise descriptions, and package each skill before marking it done.

- Use Australian spelling in public copy.

- Never put secrets in files or examples.

## Publish Boundary

Canonical GitHub repo: `Sendmux/skills`, with `main` as the default branch. Keep public examples on `npx skills add Sendmux/skills`.

Do not publish a new release, register/update skills.sh metadata, or publish docs without explicit approval.

Skill content changes merged to `main` are not complete until a new public GitHub release is created and verified. Bump `openclaw.skills.json` to the next SemVer version, tag/release that exact version, verify `gh release view`, and verify the relevant publishing/sync workflows before reporting the skill work complete.

For multiline GitHub release notes, use `gh release ... --notes-file -` or a real notes file; never pass escaped `\n` strings. Verify the saved body has real Markdown line breaks before reporting success.
