OVERVIEW

Entry index.ts orchestrates a 7-step initialization. Total: 1340 source files + 701 tests across the directories below. Cross-cutting helpers live in shared/; module boundaries are established by 122 barrel index.ts files.

KEY FILES

File	Purpose
index.ts	Plugin entry; default-exports pluginModule: PluginModule with { id, server }
plugin-config.ts	JSONC parse, multi-level merge (user + walked project), Zod v4 validation, migration
plugin-state.ts	createModelCacheState() — model resolution cache shared across handlers
plugin-interface.ts	10 OpenCode hook handlers wired into Hooks
create-managers.ts	TmuxSessionManager, BackgroundManager, SkillMcpManager, ConfigHandler
create-tools.ts	SkillContext + AvailableCategories + ToolRegistry composition
create-hooks.ts	5-tier composition: createCoreHooks() + createContinuationHooks() + createSkillHooks()
create-runtime-tmux-config.ts	isTmuxIntegrationEnabled() + createRuntimeTmuxConfig()

INITIALIZATION (7 STEPS)

serverPlugin(input, options)
  1. installAgentSortShim()        # patches Array.prototype.{toSorted,sort} for canonical agent ordering
  2. initConfigContext()           # detects opencode-vs-openagent config layout
  3. detectExternalSkillPlugin()   # warn if conflicting plugin loaded
  4. injectServerAuthIntoClient()  # wire auth headers into shared SDK client
  5. loadPluginConfig()            # walk project + user JSONC → Zod safeParse → migrate
  6a. initializeOpenClaw()         # if openclaw config present (start reply-listener daemon)
  6b. checkTeamModeDependencies()  # if team_mode.enabled (verify git, tmux, ensure ~/.omo/teams/)
  7. createManagers/Tools/Hooks/PluginInterface

CONFIG LOADING (Phase pipeline)

loadPluginConfig(directory, ctx)
  1. User: ~/.config/opencode/oh-my-openagent.jsonc (legacy: oh-my-opencode.jsonc)
  2. Walked configs: <pwd up to $HOME>/.opencode/oh-my-openagent.jsonc
  3. mergeConfigs(user, walked)
     - agents/categories/claude_code: deepMerge (recursive, prototype-pollution safe)
     - disabled_*: Set union
     - mcp_env_allowlist: user-only (security)
     - others: override replaces
  4. Zod safeParse → defaults for omitted fields
  5. migrateConfigFile() → idempotent via _migrations tracking + timestamped backups

HOOK COMPOSITION (5-tier)

Counts verified from each composer's return object. Numbers in brackets show counts when team_mode.enabled.

  Direct event handlers (src/plugin/event.ts, when team_mode.enabled): +4
    team-idle-wake-hint, team-lead-orphan-handler,
    team-member-error-handler, team-member-status-handler

Total: 54 base, 61 with team-mode. Each tier produces an object whose values are (input, output) => void handlers; the matching OpenCode handler invokes them in registration order via safeHook() wrappers.

NOTES

• plugin-interface.ts is the only layer that talks to OpenCode's Plugin API. Every other file goes through it.
• Reach for shared/ before adding helpers anywhere else — duplicate utilities WILL be flagged in review.
• Path aliases are forbidden. Use relative imports within a module, barrel imports across modules.
