Portable and Safe Skills

Use skill-creator

  • Follow the skill-creator workflow for skill structure, naming, and packaging.
  • Keep SKILL.md short and move detailed content to references/ or assets/.

Required dependency

  • Use mbt-wasip1-tools for concrete CLI patterns (echo, wc, read/write) and example project structure.

Constraints to document

  • WASIp1 path resolution uses longest-prefix matching against preopen names. No cwd. No fallback.
  • Absolute paths only work if a preopen named / (or starting with /) exists.
  • Stdio is unified: @wasi/stdio values implement both sync and async reader/writer traits.

Minimal workflow

  1. Start from an assets/ example in mbt-wasip1-tools.
  2. Keep logic simple and deterministic; only I/O is async.
  3. Document the required wasmtime run --dir host::guest usage and expected preopens.
  4. Add a README to each example with build/run commands.
  5. Package the skill using the skill-creator guidelines when done.
