What problem does it solve? Distribution commands and skills must stay project-agnostic, yet real projects need their own context, rules, checks, acceptance gates, and prohibitions applied at runtime. This Skill resolves the matching project extension file under .agentdev/extensions/skills/ so project-specific behavior is injected without modifying distribution bodies. ## Core Features & Use Cases - Extension Discovery and State Classification: Locates the single extension file matching the calling skill and classifies it as missing, malformed, migration-required (legacy kind), schema-violation (unknown kind), or valid, applying the correct stop or fail-open behavior for each state. - Five-Section Reading: Reads context, rules, checks, acceptance_gates, and must_not sections as additions to standard behavior, never as replacements, in the order Workflow Extension, internal Workflow Extension, Capability Skill Extension. - Delegation Extraction: Extracts project-local skill delegation targets from rules and checks entries that declare a skill field. - Use Case: A project defines .agentdev/extensions/skills/case-run.yaml with extra checks and a must_not list; when the case-run workflow skill executes, this resolver loads that extension, validates its kind literal, and applies the added gates before completion. ## Quick Start Ask the agent to load the project extension for the current workflow skill from .agentdev/extensions/skills and apply its context, rules, checks, acceptance gates, and must_not entries.
