#20415: fix(extensions): use dist/ import paths for bundled extensions

## Summary - **Problem:** Two bundled extensions (`twitch` and `llm-task`) import runtime values from `../../../src/` paths that don't exist in npm/brew-installed builds, causing `Cannot find module` errors - **Why it matters:** The twitch extension and llm-task tool are completely broken for all non-source-checkout users (npm, brew, global installs) since at least 2026.2.12 - **What changed:** Runtime value imports now use the proper export surfaces (`openclaw/plugin-sdk/account-id` alias for twitch, `dist/extensionAPI.js` dynamic fallback for llm-task) - **What did NOT change:** `import type` statements still point to `src/` — these are erased at compile time and cause no runtime errors. No behavior, config, or API changes. ## Change Type (select all) - [x] Bug fix - [ ] Feature - [ ] Refactor - [ ] Docs - [ ] Security hardening - [ ] Chore/infra ## Scope (select all touched areas) - [ ] Gateway / orchestration - [x] Skills / tool execution - [ ] Auth / tokens - [ ] Memory / storage - [x] Integrations - [ ] API / contracts - [ ] UI / DX - [ ] CI/CD / infra ## Linked Issue/PR - Fixes #20548 - Closes #19053 - Closes #18846 - Closes #16182 - Related #15686 ## User-visible / Behavior Changes - Twitch extension loads successfully on npm/brew installs (was crashing on import) - `llm-task` tool works on npm/brew installs (was failing with "Cannot find module") ## Security Impact (required) - New permissions/capabilities? `No` - Secrets/tokens handling changed? `No` - New/changed network calls? `No` - Command/tool execution surface changed? `No` - Data access scope changed? `No` ## Repro + Verification ### Environment - OS: Any - Runtime/container: Node.js (npm/brew global install) - Model/provider: N/A - Integration/channel: Twitch, llm-task ### Steps 1. `npm install -g openclaw@latest` 2. Configure twitch channel or call `llm-task` tool 3. Observe `Cannot find module '../../../src/routing/session-key.js'` (twitch) or `Cannot find module '../../../src/agents/pi-embedded-runner.js'` (llm-task) ### Expected - Extensions load and function correctly ### Actual - Both extensions crash with module-not-found errors ## Evidence - [x] Failing test/log before + passing after - [x] Trace/log snippets - [ ] Screenshot/recording - [ ] Perf numbers (if relevant) Error logs from issues #19053, #18846, #16182 all show identical `Cannot find module` errors. After fix: both extensions load without errors. **Root cause in `llm-task-tool.ts`** — the "fallback" import path (line 28) is identical to the primary path (line 17). Both try `../../../src/agents/pi-embedded-runner.js`. This is a copy-paste bug. The correct fallback is `dist/extensionAPI.js` which exports `runEmbeddedPiAgent`. **Root cause in `token.ts`** — static import from `../../../src/routing/session-key.js` which doesn't exist in production builds. The `openclaw/plugin-sdk/account-id` alias re-exports the same symbols and resolves correctly in both dev and production. ## Human Verification (required) - Verified scenarios: Confirmed `dist/plugin-sdk/index.js` exports `DEFAULT_ACCOUNT_ID` and `normalizeAccountId`; confirmed `dist/extensionAPI.js` exports `runEmbeddedPiAgent`; confirmed `import type` statements are erased at compile time. Both extensions load and initialize successfully after the fix. - Edge cases checked: Dev environment (src/ path still works as primary for llm-task), type-only imports unaffected, `openclaw/plugin-sdk/account-id` alias resolves via package.json exports at runtime and tsconfig paths at type-check time - What you did **not** verify: Full integration test on npm global install (verified by code inspection and issue reports) ## Compatibility / Migration - Backward compatible? `Yes` - Config/env changes? `No` - Migration needed? `No` ## Failure Recovery (if this breaks) - How to disable/revert this change quickly: `git revert <commit>` - Files/config to restore: `extensions/twitch/src/token.ts`, `extensions/llm-task/src/llm-task-tool.ts` - Known bad symptoms reviewers should watch for: Module resolution errors mentioning `plugin-sdk/account-id` or `dist/extensionAPI` ## Risks and Mitigations - Risk: `openclaw/plugin-sdk/account-id` alias or `dist/extensionAPI.js` could be renamed in a future refactor - Mitigation: These are public API surfaces used by many extensions (googlechat, IRC, voice-call). Renaming would break all extensions, not just these two. **Note:** The same `src/`-import pattern may affect other extensions (see #15686 which reports memory-core, telegram, voice-call, whatsapp). A follow-up lint rule to flag non-type imports from `src/` in `extensions/` could prevent recurrence. ## AI-assisted This PR was AI-assisted.
