WHERE TO LOOK

Task	Location	Notes
Add agent	src/agents/	Create .ts, add to builtinAgents, update types.ts
Add hook	src/hooks/	Dir with createXXXHook(), export from index.ts
Add tool	src/tools/	Dir with constants/types/tools.ts, add to builtinTools
Add MCP	src/mcp/	Create config, add to index.ts
Add skill	src/features/builtin-skills/	Dir with SKILL.md
Config schema	src/config/schema.ts	Run bun run build:schema after
Claude Code compat	src/features/claude-code-*-loader/	Command, skill, agent, mcp loaders

CONVENTIONS

• Bun only: bun run, bun test, bunx (NEVER npm/npx)
• Types: bun-types (not @types/node)
• Build: bun build (ESM) + tsc --emitDeclarationOnly
• Exports: Barrel pattern in index.ts; explicit named exports for tools/hooks
• Naming: kebab-case directories, createXXXHook/createXXXTool factories
• Testing: BDD comments #given, #when, #then (same as AAA)
• Temperature: 0.1 for code agents, max 0.3

ANTI-PATTERNS

Category	Forbidden
Type Safety	as any, @ts-ignore, @ts-expect-error
Package Manager	npm, yarn, npx
File Ops	Bash mkdir/touch/rm for code file creation
Publishing	Direct bun publish, local version bump
Agent Behavior	High temp (>0.3), broad tool access, sequential agent calls
Hooks	Heavy PreToolUse logic, blocking without reason
Year	2024 in code/prompts (use current year)

AGENT MODELS

Agent	Model	Purpose
Sisyphus	anthropic/claude-opus-4-5	Primary orchestrator
oracle	openai/gpt-5.2	Strategy, code review
librarian	anthropic/claude-sonnet-4-5	Docs, OSS research
explore	opencode/grok-code	Fast codebase grep
frontend-ui-ux-engineer	google/gemini-3-pro-preview	UI generation
document-writer	google/gemini-3-pro-preview	Technical docs
multimodal-looker	google/gemini-3-flash	PDF/image analysis

COMMANDS

bun run typecheck      # Type check
bun run build          # ESM + declarations + schema
bun run rebuild        # Clean + Build
bun test               # Run tests (380+)

DEPLOYMENT

GitHub Actions workflow_dispatch only

1. Never modify package.json version locally
2. Commit & push to dev
3. Trigger: gh workflow run publish -f bump=patch|minor|major

CI auto-commits schema changes on master, maintains rolling next draft release on dev.

COMPLEXITY HOTSPOTS

File	Lines	Description
src/index.ts	464	Main plugin, all hook/tool init
src/cli/config-manager.ts	669	JSONC parsing, env detection
src/auth/antigravity/fetch.ts	621	Token refresh, URL rewriting
src/tools/lsp/client.ts	611	LSP protocol, JSON-RPC
src/hooks/anthropic-context-window-limit-recovery/executor.ts	564	Multi-stage recovery
src/agents/sisyphus.ts	504	Orchestrator prompt

NOTES

• OpenCode: Requires >= 1.0.150
• Config: ~/.config/opencode/oh-my-opencode.json or .opencode/oh-my-opencode.json
• JSONC: Config files support comments and trailing commas
• Claude Code: Full compat layer for settings.json hooks, commands, skills, agents, MCPs
• Skill MCP: Skills can embed MCP server configs in YAML frontmatter
