What problem does it solve? Authoring a reusable Agent Skill package requires consistent structure, correct SKILL.md frontmatter, triggering validation, and runtime-specific packaging, which is error-prone when done ad hoc. This Skill turns an approved capability brief into a validated, distributable Skill package while keeping portable Skills separate from Persona-specific applications and workflows. ## Core Features & Use Cases - Package Authoring: Convert a bounded capability definition into a complete SKILL.md with supporting references, scripts, or assets using progressive disclosure. - Validation and Evaluation: Run structural validation plus positive and negative triggering tests, edge cases, fallbacks, and regression checks for target agent runtimes. - Boundary Governance: Enforce placement gates, change-impact reconciliation, and separation between reusable Skills, Persona applications, workflows, and Tool-use recipes. - Use Case: A team wants to publish a new reusable Skill for multiple agent runtimes. Use this Skill to define the contract, author the package, validate triggering behavior, and reconcile repository routes before release. ## Quick Start Use pl-skill-creator to turn this capability brief into a validated portable Skill package with triggering tests and evaluation evidence.
