What problem does it solve? Writing a skill for the APX super-agent requires knowing where the loader scans, how the frontmatter description triggers loading, and what body style the model expects. This Skill encodes those conventions so a new skill is discoverable and loads correctly on the first try. ## Core Features & Use Cases - File location rules: Explains the three scanned locations (project .apc/skills/, user-global ~/.apx/skills/, and runtime-internal src/core/runtime-skills/) and warns that <repo>/skills/ is never loaded by the super-agent. - Frontmatter and trigger guidance: Shows how to write the description field as a trigger condition with user phrases, plus the scope values (public, internal, optional). - Body style and workflow: Prescribes an opinionated structure (what-it-is paragraph, CLI calls, schema, anti-examples) with an 80-200 line budget, plus verification via apx skills list and apx exec. - Use Case: A developer adding a new capability to the APX super-agent uses this Skill to scaffold src/core/runtime-skills/my-thing/SKILL.md, write a triggerable description, and confirm it appears in apx skills list without restarting the daemon. ## Quick Start Ask the agent to load the apx-skill-builder skill and walk you through creating a new skill named my-thing in the runtime-skills directory.
