What does this PR do?

  • Loads each SKILL.md directory as a regular generated Skill whose class documentation comes from the skill file.
  • Exposes a deterministic, skill-root-relative files: list[SkillFile] manifest.
  • Injects a skill-local ShellTools(cwd=skill_root) and removes the bespoke read_file() / run_script() surface.
  • Rebuilds documentation, files, and the shell on agent-local registry reload.
  • Updates tests, the quickstart, migration guidance, and the changelog.

A skill-local shell keeps every manifest path directly usable from the skill root and preserves the per-agent object isolation introduced by #127.

📝 Walkthrough

Walkthrough

Text skills now load as standard Skill objects. Each object derives documentation from SKILL.md, exposes a stable SkillFile manifest, and uses root-scoped ShellTools. Legacy file and script helpers were removed, with compatibility and reload behavior documented and tested.

Changes

Text skill object model

Layer / File(s) Summary
Skill metadata and lifecycle contracts
src/nooa/skill.py, src/nooa/__init__.py
Adds public SkillFile metadata, deterministic file discovery, symlink exclusion, and asynchronous detach support.
Generated text-skill loading
src/nooa/skill.py
Loads SKILL.md, creates generated Skill instances, injects root-scoped ShellTools, and removes bespoke read_file() and run_script() methods.
Validation and migration coverage
tests/unit/test_skill.py, tests/test_skill_registry_extended.py, examples/README.md, examples/quickstart/10_skills.py, skills/nooa-tools-and-skills/SKILL.md, CHANGELOG.md
Tests manifests, shell operations, documentation, helper removal, registry reloads, and distinct shell instances. Examples and documentation describe the updated API.
