Summary

Complete the Caveman OpenCode Plugin implementation by adding missing files:

Added Files

• \package.json\ - Plugin metadata, dependencies (@opencode/plugin, zod), peerDependencies (@opencode-ai/plugin), and npm scripts (typecheck, build, dev, test)
• \options-validator.ts\ - Validates plugin config (defaultLevel, enabled) with fallbacks to hardcoded defaults
• \ sconfig.json\ - Extends @tsconfig/node22, strict mode, nodenext modules, declaration output
• \ est/command-loader.test.ts\ - Tests for command metadata loading from frontmatter
• \ est/index.test.ts\ - Comprehensive tests for plugin setup, skill/command registration, context hook, storage integration, and v1 server()
• \ est/options-validator.test.ts\ - Tests for config validation (defaults, valid levels, invalid levels, enabled flag)
• \ est/skill-loader.test.ts\ - Tests for skill markdown parsing and loading

Existing Files (from origin/main)

• \index.ts\ - Dual v1/v2 plugin entrypoint with setup() and server()
• \skill-loader.ts\ - Loads 5 skills from .opencode/skills/ at runtime
• \command-loader.ts\ - Loads 5 commands from .opencode/commands/ at runtime
• \rontmatter.ts\ - Shared frontmatter parser (eliminates duplication)
• \storage-keys.ts\ - Single source of truth for VALID_LEVELS enum
• \ est/enum-sync.test.ts\ - Ensures skill/command docs stay in sync with VALID_LEVELS

Verification

• All 34 tests pass (5 test files)
• TypeScript strict mode compiles clean
• Build emits declarations to dist/

Follow-up Work (out of scope for this PR)

Per the spec's recommended follow-up:

1. Add \�utoinvoke: true\ to caveman skill frontmatter
2. Align level names (wenyan vs wenyan-full) across 4 locations
3. Guard prompt.text in command execute
4. Strengthen storage narrowing
5. Remove async from server()
6. Centralize level enum handling further

Implements issue #13 (SPEC: Caveman OpenCode Plugin Implementation and Follow-up)
