 This guide summarizes how to explore, modify, and validate the WhatsApp HTTP API
 (WAHA) codebase when assisting as an automation or coding agent.
 
-- When you asked to refactor or "apply new lib" instead of current one - do not
-  change the behavior, make a minimum amount of changes possible. If you see
-  some edge case during that process that haven't been covered - tell it,
-  suggest fix, but don't change the code.
-
 ## Product & Variants
 
-- WAHA ships in **Core** and **Plus** editions. Core lives under `src/core` and
-  only supports the default session plus minimal media features. Plus extends
-  core via `src/plus` to add multi-session orchestration, richer media handling,
-  and external storage integrations.
-- Core code must remain free from Plus-only references. A pre-commit hook
-  rejects the word `plus` inside core files; reuse abstractions exposed through
-  `@waha/core/**` instead of importing Plus modules from Core.
-- Commit subjects are validated: changes that touch `src/plus` require a
-  `[PLUS] …` prefix and must not include non-Plus files; everything else must
-  use `[core] …`. Verify against `./.precommit/validate_commit_message.py` if
-  unsure.

+## Key Paths
 
-- `src/main.ts`: runtime entry point; dynamically loads the correct AppModule
-  (Core vs Plus) and configures global interceptors/filters.
-- `src/api/**`: REST controllers and WebSocket gateway. Keep handlers thin;
-  delegate to managers/services. HTTP routes follow `/api/{sessionName}/…`;
-  always thread the session name through request DTOs and guards instead of
-  hardcoding `default`.

 - `src/plus/**`: multi-session orchestration, advanced media services, and

-  services.

 - `src/structures/**` and `src/utils/**`: DTOs, enums (event names follow
-  `domain.action`), helper utilities. Maintain naming consistency when
-  introducing new events.
-- `tests/**`: Jest-based suites; do not add new tests unless explicitly asked,
-  but keep existing tests working.
+  `domain.action`), helper utilities
 
 ## Coding Expectations
 
-- Favor composable, long-lived solutions. If a helper already exists (e.g.,
-  `parseBool`, `DefaultMap`, media factories), extend it instead of reinventing
-  logic. Lodash ships with the project—prefer its utilities over hand-rolled
-  helpers. Import lodash as a namespace (`import * as lodash from 'lodash';`) so
-  helpers like `lodash.camelCase` stay consistent across files. When a new
-  third-party library seems necessary, confirm with the user, especially if the
-  package looks stale.
+- Favor composability and long-lived solutions
+- Reuse existing helpers (`parseBool`, `DefaultMap`, media factories) instead of
+  reinventing logic
 - Stick to NestJS patterns: inject dependencies through constructors, expose
-  provider tokens from modules, and keep controllers free from business logic.
+  provider tokens from modules
 - Logging goes through injected `PinoLogger` or helpers in
-  `src/utils/logging.ts`. `console.log` is blocked by pre-commit.
-- Respect path aliases (`@waha/...`) defined in `tsconfig.json`; keep imports
-  consistent (use absolute aliases, not relative `../../../`).
-- Prefer named function declarations over `const` arrow functions when possible.
-- Avoid naming unused variables with a leading underscore; if a parameter is
-  required by a signature, explicitly `void` it instead.
-- Do not write verbose ternaries like
-  `condition !== undefined ? condition : default`; use idiomatic helpers such as
-  `??` (nullish coalescing) or existing boolean parsers so flags stay readable.
-- Do not place `await` or other async calls inside ternary expressions (`?:`);
-  use explicit `if/else` blocks instead.
-- For configs, prefer runtime configurability over constants. Environment keys
-  follow `WAHA_*` for global values and `WAHA_SESSION_CONFIG_*` /
-  `session.config.*` for per-session overrides. If both env and config are
-  supported, honor both (`WAHA_WEBJS_CONFIG_*` vs. `session.webjs.config.*`).

-## Language & Localization
-
-- Keep identifiers (classes, methods, variables) and code comments in English so
-  the codebase stays consistent for the global team.
-- Route user-visible strings through the existing i18n structure rather than
-  hardcoding text. ChatWoot copy belongs in `src/apps/chatwoot/i18n` with
-  English as the source locale before adding translations.
-
-## ChatWoot Integration Notes
-
-- Avoid introducing synthetic events; map onto existing webhook or engine events
-  whenever plausible. Always use the official ChatWoot API client located in
-  `src/apps/chatwoot/client`.
-- When adding events, align consumer names with webhook/event identifiers (e.g.,
-  `message.any`).
-
-## Workflow Checklist
-
-1. Identify whether work targets Core, Plus, or shared layers. If Plus-only,
-   isolate changes to `src/plus` and ensure the commit prefix matches.
-2. Lean on existing services/managers; extend the appropriate session manager
-   rather than branching logic inline.
-3. After edits run:
-   - Do **not** run `pre-commit run --all-files` unless the user explicitly
-     asks.
-   - `yarn build`
-   - `yarn test --watchman=false`
-4. Do **not** start the application yourself; ask the user to run it if runtime
-   validation is required.
-5. Capture any assumptions or open questions for the user, especially when
-   touching configs, introducing dependencies, or modifying public APIs.
-
-## Additional Tips
-
-- Concurrency-sensitive sections (session start/stop) rely on `async-lock`. When
-  adding async flows, reuse `SessionManager.withLock` or existing retry
-  utilities (`promiseTimeout`, `waitUntil`).
-- Media features centralize through `MediaManager` and `MediaStorageFactory`.
-  When altering media behavior, update both Core and Plus variants where
-  applicable.
-- Keep docs and code ASCII unless a file already uses other characters. When
-  updating documentation, mirror the concise, actionable tone used here.
-
-## Yes No
-
-Always define key for objects (and in return too)
-
-```js
-// NO
-const variable = 123;
-const b = { variable };
-
-// YES
-const variable = 123;
-const b = { variable: variable };
-```
-
-Use the three-line comment style for section headers inside files:
-
-```ts
-// NO
-// ─── Section name ─────────────────────────────────────────────────────────────
-
-// YES
-//
-// Section name
-//
-```

-before the method runs, keeping the session ONLINE during API activity and

+MCP tools live in `src/apps/mcp/tools/` and expose the HTTP API to AI clients.
+Each tool file mirrors an API domain (e.g. `chats.tools.ts` → chats endpoints).
+
+**When you change an existing API endpoint:**
+
+- Check the corresponding `*.tools.ts` file and update the tool's `inputSchema`,
+  description, or behavior if the API signature changed.
+
+**When you add a new API endpoint:**
+
+- Ask the user whether an MCP tool is needed for the new endpoint before
+  creating one.
+- If yes, add the tool to the matching `*.tools.ts` file (or create a new file
+  for a new domain).
+- Every `@Tool` decorator must include an `annotations` block with all three
+  fields:
+  ```typescript
+  annotations: {
+    readOnlyHint: true | false,   // true = no side effects (GET-style)
+    destructiveHint: true | false, // true = irreversible deletion/logout
+    idempotentHint: true | false,  // true = safe to repeat with same args
+  }
+  ```
+- Input schemas live in the matching `*.zod.ts` file.
+- Tools call the API via `this.textRequest({ method, url, ... })` inherited from
+  `McpController`.
