[misyuari]

Summary

• Implement disabled_skills config support in createBuiltinSkills() to allow filtering skills at source
• Propagate disabledSkills through skill resolution functions, agent creation, and config handler
• Add comprehensive tests for disabled skill filtering behavior

Changes

• src/features/builtin-skills/skills.ts: Add optional { disabledSkills?: Set } parameter to createBuiltinSkills() and filter returned skills array
• src/features/opencode-skill-loader/skill-content.ts:
  • Add disabledSkills to SkillResolutionOptions interface
  • Update getAllSkills(), resolveSkillContent(), resolveMultipleSkills(), and async variants to pass and respect disabled skills
  • Bypass cache when disabled skills are provided to ensure correct filtering
• src/agents/utils.ts: Add disabledSkills parameter to createBuiltinAgents() and pass to createBuiltinSkills()
• src/plugin-handlers/config-handler.ts: Create disabledSkills set from pluginConfig.disabled_skills and pass to createBuiltinAgents()
• src/index.ts: Pass disabledSkills to createBuiltinSkills() call, removing redundant manual filtering
• Tests: Add 18+ new test cases across skills.test.ts, skill-content.test.ts, and utils.test.ts covering disabled skill scenarios

Summary by cubic

Adds support for disabling specific skills via pluginConfig.disabled_skills, ensuring disabled skills are filtered at the source and treated as not found in resolution and agent prompts. Removes redundant manual filtering and keeps agent prompts accurate.

• New Features

  • createBuiltinSkills now accepts disabledSkills and filters built-in skills.
  • Skill resolution (sync/async) respects disabledSkills.
  • createBuiltinAgents passes disabledSkills to built-in skills; agent prompts exclude disabled skills.
  • Config handler reads pluginConfig.disabled_skills and wires it through to agents/skills.
  • Added tests covering disabled skill behavior across loaders, agents, and built-ins.

• Dependencies

  • Bumped oh-my-opencode optional binaries to 3.0.1 across all platforms.
