Module skill 

Bundled agent skills — decided skill (PORT-CONTRACT.d/15).

Port of src/rac/core/skills.py (registry + resource loading) and src/asdecided/services/skill.py (install_skills). The packaged SKILL.md resources are embedded verbatim from rust/decided-engine/assets/skills/, vendored byte-identical copies of the Python package files — a unit test below pins that identity, because the installed file must be byte-identical to what the oracle installs (skill brief, landmine 1).

SkillResourceMissing (a broken Python installation) has no Rust equivalent: embedded resources cannot be absent from a linked binary.

Structs

InstalledSkill

One installed skill (InstalledSkill; bytes_written is in the oracle’s model but deliberately absent from its JSON, so it is not carried here).

SkillInstallation

Result of a decided skill install run.

SkillSpec

One bundled skill: name and one-line description, registry order.

Enums

SkillInstallError

The failure contract of install_skills, message-shaped like the oracle.

Constants

BUNDLED_SKILLS

Bundled skills, in registry order (BUNDLED_SKILLS). install with no name installs all of them; list enumerates them.

Functions

available_skills

available_skills() — bundled skill names, registry order.

install_skills

install_skills(target_dir, skill_name) — write bundled skills into <dir>/.claude/skills/<name>/SKILL.md.
