Overview

Resolves assignment metadata from skill frontmatter.

Flow: 1) Find SKILL.md by skill name (e.g., “ace-task-work”) 2) Read workflow binding from skill.execution.workflow (fallback: assign.source) 3) Resolve workflow file from URI 4) Parse workflow assign frontmatter (sub-steps/context)

Instance Method Details

#assign_capable_skill_names ⇒ Array<String>

List assign-capable canonical skills discovered from skill sources.

Assign-capable skills are canonical skills with:

  • skill.kind: workflow|orchestration

  • workflow binding present (skill.execution.workflow or assign.source)

Returns:

  • (Array<String>) —

    Skill names

Raises:

end

#assign_step_catalog ⇒ Array<Hash>

Build assignment step entries from canonical skills.

Only steps declared under ‘assign.steps` are emitted here. This keeps canonical skills authoritative for public skill-backed assignment steps, while internal helper steps can continue to use catalog templates.

Returns:

  • (Array<Hash>) —

    Step definitions keyed by canonical precedence
