-## 7. TypeScript Conversion
+## 7. Coding Standards
+
+For detailed coding conventions, workspace boundaries, and architecture guidance, refer to the [`AGENTS.md`](../AGENTS.md) file at the project root. It covers code style, type safety, import ordering, iteration/performance expectations, frontend rules, testing, and development commands.
+
+## 8. TypeScript Conversion
1. **Original State**: The project was initially developed entirely in JavaScript (JS).
-2. **Frontend Transition**:
- - We are in the process of transitioning the frontend from JS to TypeScript (TS).
- - The transition is nearing completion.
- - This conversion is feasible due to React's capability to intermix JS and TS prior to code compilation. It's standard practice to compile/bundle the code in such scenarios.
+2. **Frontend**: Fully transitioned to TypeScript.
-3. **Backend Considerations**:
- - Transitioning the backend to TypeScript would be a more intricate process, especially for an established Express.js server.
-
- - **Options for Transition**:
- - **Single Phase Overhaul**: This involves converting the entire backend to TypeScript in one go. It's the most straightforward approach but can be disruptive, especially for larger codebases.
-
- - **Incremental Transition**: Convert parts of the backend progressively. This can be done by:
- - Maintaining a separate directory for TypeScript files.
- - Gradually migrating and testing individual modules or routes.
- - Using a build tool like `tsc` to compile TypeScript files independently until the entire transition is complete.
-
- - **Compilation Considerations**:
- - Introducing a compilation step for the server is an option. This would involve using tools like `ts-node` for development and `tsc` for production builds.
- - However, this is not a conventional approach for Express.js servers and could introduce added complexity, especially in terms of build and deployment processes.
-
- - **Current Stance**: At present, this backend transition is of lower priority and might not be pursued.
+3. **Backend**:
+ - The legacy Express.js server remains in `/api` as JavaScript.
+ - All new backend code is written in TypeScript under `/packages/api`, which is compiled and consumed by `/api`.
+ - Shared database logic lives in `/packages/data-schemas` (TypeScript).
+ - Shared frontend/backend API types and services live in `/packages/data-provider` (TypeScript).
+ - Minimize direct changes to `/api`; prefer adding TypeScript code to `/packages/api` and importing it.
-## 8. Module Import Conventions
+## 9. Module Import Conventions
-- `npm` packages first,
- - from longest line (top) to shortest (bottom)
+Imports are organized into three sections (in order):
-- Followed by typescript types (pertains to data-provider and client workspaces)
- - longest line (top) to shortest (bottom)
- - types from package come first
+1. **Package imports** — sorted from shortest to longest line length.
+ - `react` is always the first import.
+ - Multi-line (stacked) imports count their total character length across all lines for sorting.
-- Lastly, local imports
- - longest line (top) to shortest (bottom)
- - imports with alias `~` treated the same as relative import with respect to line length
+2. **`import type` imports** — sorted from longest to shortest line length.
+ - Package type imports come first, then local type imports.
+ - Line length sorting resets between the package and local sub-groups.
+
+3. **Local/project imports** — sorted from longest to shortest line length.
+ - Multi-line (stacked) imports count their total character length across all lines for sorting.
+ - Imports with alias `~` are treated the same as relative imports with respect to line length.
+
+- Consolidate value imports from the same module as much as possible.
+- Always use standalone `import type { ... }` for type imports; never use inline `type` keyword inside value imports (e.g., `import { Foo, type Bar }` is wrong).
**Note:** ESLint will automatically enforce these import conventions when you run `npm run lint --fix` or through pre-commit hooks.

+# LibreChat
+
+## Project Overview
+
+LibreChat is a monorepo with the following key workspaces:
+
+| Workspace | Language | Side | Dependency | Purpose |
+|---|---|---|---|---|
+| `/api` | JS (legacy) | Backend | `packages/api`, `packages/data-schemas`, `packages/data-provider`, `@librechat/agents` | Express server — minimize changes here |
+| `/packages/api` | **TypeScript** | Backend | `packages/data-schemas`, `packages/data-provider` | New backend code lives here (TS only, consumed by `/api`) |
+| `/packages/data-schemas` | TypeScript | Backend | `packages/data-provider` | Database models/schemas, shareable across backend projects |
+| `/packages/data-provider` | TypeScript | Shared | — | Shared API types, endpoints, data-service — used by both frontend and backend |
+| `/client` | TypeScript/React | Frontend | `packages/data-provider`, `packages/client` | Frontend SPA |
+| `/packages/client` | TypeScript | Frontend | `packages/data-provider` | Shared frontend utilities |
+
+The source code for `@librechat/agents` (major backend dependency, same team) is at `/home/danny/agentus`.
+
+---
+
+## Workspace Boundaries
+
+- **All new backend code must be TypeScript** in `/packages/api`.
+- Keep `/api` changes to the absolute minimum (thin JS wrappers calling into `/packages/api`).
+- Database-specific shared logic goes in `/packages/data-schemas`.
+- Frontend/backend shared API logic (endpoints, types, data-service) goes in `/packages/data-provider`.
+- Build data-provider from project root: `npm run build:data-provider`.
+
+---
+
+## Code Style
+
+### Structure and Clarity
+
+- **Never-nesting**: early returns, flat code, minimal indentation. Break complex operations into well-named helpers.
+- **Functional first**: pure functions, immutable data, `map`/`filter`/`reduce` over imperative loops. Only reach for OOP when it clearly improves domain modeling or state encapsulation.
+- **No dynamic imports** unless absolutely necessary.
+
+### DRY
+
+- Extract repeated logic into utility functions.
+- Reusable hooks / higher-order components for UI patterns.
+- Parameterized helpers instead of near-duplicate functions.
+- Constants for repeated values; configuration objects over duplicated init code.
+- Shared validators, centralized error handling, single source of truth for business rules.
+- Shared typing system with interfaces/types extending common base definitions.
+- Abstraction layers for external API interactions.
+
+### Iteration and Performance
+
+- **Minimize looping** — especially over shared data structures like message arrays, which are iterated frequently throughout the codebase. Every additional pass adds up at scale.
+- Consolidate sequential O(n) operations into a single pass whenever possible; never loop over the same collection twice if the work can be combined.
+- Choose data structures that reduce the need to iterate (e.g., `Map`/`Set` for lookups instead of `Array.find`/`Array.includes`).
+- Avoid unnecessary object creation; consider space-time tradeoffs.
+- Prevent memory leaks: careful with closures, dispose resources/event listeners, no circular references.
+
+### Type Safety
+
+- **Never use `any`**. Explicit types for all parameters, return values, and variables.
+- **Limit `unknown`** — avoid `unknown`, `Record`, and `as unknown as T` assertions. A `Record` almost always signals a missing explicit type definition.
+- **Don't duplicate types** — before defining a new type, check whether it already exists in the project (especially `packages/data-provider`). Reuse and extend existing types rather than creating redundant definitions.
+- Use union types, generics, and interfaces appropriately.
+- All TypeScript and ESLint warnings/errors must be addressed — do not leave unresolved diagnostics.
+
+### Comments and Documentation
+
+- Write self-documenting code; no inline comments narrating what code does.
+- JSDoc only for complex/non-obvious logic or intellisense on public APIs.
+- Single-line JSDoc for brief docs, multi-line for complex cases.
+- Avoid standalone `//` comments unless absolutely necessary.
+
+### Import Order
+
+Imports are organized into three sections:
+
+1. **Package imports** — sorted shortest to longest line length (`react` always first).
+2. **`import type` imports** — sorted longest to shortest (package types first, then local types; length resets between sub-groups).
+3. **Local/project imports** — sorted longest to shortest.
+
+Multi-line imports count total character length across all lines. Consolidate value imports from the same module. Always use standalone `import type { ... }` — never inline `type` inside value imports.
+
+### JS/TS Loop Preferences
+
+- **Limit looping as much as possible.** Prefer single-pass transformations and avoid re-iterating the same data.
+- `for (let i = 0; ...)` for performance-critical or index-dependent operations.
+- `for...of` for simple array iteration.
+- `for...in` only for object property enumeration.
+
+---
+
+## Frontend Rules (`client/src/**/*`)
+
+### Localization
+
+- All user-facing text must use `useLocalize()`.
+- Only update English keys in `client/src/locales/en/translation.json` (other languages are automated externally).
+- Semantic key prefixes: `com_ui_`, `com_assistants_`, etc.
+
+### Components
+
+- TypeScript for all React components with proper type imports.
+- Semantic HTML with ARIA labels (`role`, `aria-label`) for accessibility.
+- Group related components in feature directories (e.g., `SidePanel/Memories/`).
+- Use index files for clean exports.
+
+### Data Management
+
+- Feature hooks: `client/src/data-provider/[Feature]/queries.ts` → `[Feature]/index.ts` → `client/src/data-provider/index.ts`.
+- React Query (`@tanstack/react-query`) for all API interactions; proper query invalidation on mutations.
+- QueryKeys and MutationKeys in `packages/data-provider/src/keys.ts`.
+
+### Data-Provider Integration
+
+- Endpoints: `packages/data-provider/src/api-endpoints.ts`
+- Data service: `packages/data-provider/src/data-service.ts`
+- Types: `packages/data-provider/src/types/queries.ts`
+- Use `encodeURIComponent` for dynamic URL parameters.
+
+### Performance
+
+- Prioritize memory and speed efficiency at scale.
+- Cursor pagination for large datasets.
+- Proper dependency arrays to avoid unnecessary re-renders.
+- Leverage React Query caching and background refetching.
+
+---
+
+## Development Commands
+
+| Command | Purpose |
+|---|---|
+| `npm run smart-reinstall` | Install deps (if lockfile changed) + build via Turborepo |
+| `npm run reinstall` | Clean install — wipe `node_modules` and reinstall from scratch |
+| `npm run backend` | Start the backend server |
+| `npm run backend:dev` | Start backend with file watching (development) |
+| `npm run build` | Build all compiled code via Turborepo (parallel, cached) |
+| `npm run frontend` | Build all compiled code sequentially (legacy fallback) |
+| `npm run frontend:dev` | Start frontend dev server with HMR (port 3090, requires backend running) |
+| `npm run build:data-provider` | Rebuild `packages/data-provider` after changes |
+
+- Node.js: v20.19.0+ or ^22.12.0 or >= 23.0.0
+- Database: MongoDB
+- Backend runs on `http://localhost:3080/`; frontend dev server on `http://localhost:3090/`
+
+---
+
+## Testing
+
+- Framework: **Jest**, run per-workspace.
+- Run tests from their workspace directory: `cd api && npx jest `, `cd packages/api && npx jest `, etc.
+- Frontend tests: `__tests__` directories alongside components; use `test/layout-test-utils` for rendering.
+- Cover loading, success, and error states for UI/data flows.
+- Mock data-provider hooks and external dependencies.
+
+---
+
+## Formatting
+
+Fix all formatting lint errors (trailing spaces, tabs, newlines, indentation) using auto-fix when available. All TypeScript/ESLint warnings and errors **must** be resolved.

- 'Once upon a time, in a small village nestled between rolling green hills, lived a young boy named Ethan. He was curious, adventurous, and had an insatiable thirst for knowledge. Every day, he would wander through the village, eagerly listening to the stories of the villagers and observing the world around him.\n' +
- '\n' +
- 'One sunny day, while exploring the outskirts of the village, Ethan stumbled upon an old dusty book hidden amongst the roots of a majestic ancient oak tree. It was a book of fairy tales, filled with vivid descriptions of enchanted forests, magical creatures, and extraordinary adventures. Intrigued, Ethan opened the book and began reading.\n' +
- '\n' +
- 'As he turned the pages, he was transported into a world filled with wonder and awe. With each new story he read, he grew more drawn to the idea of embarking on his own grand adventure. Inspired by the tales he had discovered, Ethan decided to set off on a journey to seek out the magic and mystery that lay beyond the boundaries of his village.\n' +
- '\n' +
- 'He bid farewell to his family and set out on a path that led him to a dense and enchanting forest. The forest was said to be home to mythical creatures and hidden treasures. As Ethan ventured deeper into the woods, he could feel an electric energy, as if the trees whispered secrets to him.\n' +
- '\n' +
- 'Soon, he encountered a mischievous sprite named Sparkle, who had an impish grin and twinkling eyes. Sparkle guided Ethan through the labyrinth of trees, warning him of hidden dangers and sharing stories of ancient beings that dwelled in the heart of the forest.\n' +
- '\n' +
- 'Together, they stumbled upon a shimmering lake that seemed to glow with an otherworldly light. At the center of the lake, resting atop a small island, was a humble cottage made of petals and leaves. It belonged to an ancient and wise sorceress named Celestia.\n' +
- '\n' +
- 'Celestia had the power to grant one wish to anyone who dared to find her abode. Ethan, captivated by the tales he had read and yearning for something greater, approached the cottage with trepidation. When he shared his desire to embark on a grand adventure, Celestia smiled warmly and agreed to grant his wish.\n' +
- '\n' +
- 'With a wave of her wand and a sprinkle of stardust, Celestia bestowed upon Ethan a magical necklace. This necklace, adorned with a rare gemstone called the Eye of Imagination, had the power to turn dreams and imagination into reality. From that moment forward, Ethan\'s every thought and idea became manifest.\n' +
- '\n' +
- 'Energized by this newfound power, Ethan continued his journey, encountering mythical creatures, solving riddles, and overcoming treacherous obstacles along the way. With the Eye of Imagination, he brought life to ancient statues, unlocked hidden doors, and even tamed fiery dragons.\n' +
- '\n' +
- 'As days turned into weeks and weeks into months, Ethan became wiser and more in tune with the world around him. He learned that true adventure was not merely about seeking thrills and conquering the unknown, but also about fostering compassion, friendship, and a deep appreciation for the beauty of the ordinary.\n' +
- '\n' +
- 'Eventually, Ethan\'s journey led him back to his village. With the Eye of Imagination, he transformed the village into a place of wonders and endless possibilities. Fields blossomed into vibrant gardens, simple tools turned into intricate works of art, and the villagers felt a renewed sense of hope and inspiration.\n' +
- '\n' +
- 'Ethan, now known as the Village Magician, realized that the true magic lied within everyone\'s hearts. He taught the villagers to embrace their creativity, to dream big, and to never underestimate the power of imagination. And so, the village flourished, becoming a beacon of wonder and creativity for all to see.\n' +
- '\n' +
- 'In the years that followed, Ethan\'s adventures continued, though mostly within the confines of his beloved village. But he never forgot the thrill of that first grand adventure. And every now and then, when looking up at the starry night sky, he would allow his mind to wander, knowing that the greatest adventures were still waiting to be discovered.',

- 'Once there was a young lad by the name of Ethan, raised in a little hamlet nestled betwixt the verdant knolls, who possessed an irrepressible yearning for knowledge, a thirst unquenchable and a spirit teeming with curiosity. As the golden sun bathed the bucolic land in its effulgent light, he would tread through the village, his ears attuned to the tales spun by the townsfolk, his eyes absorbing the tapestry woven by the world surrounding him.\n' +
- '\n' +
- 'One radiant day, whilst exploring the periphery of the settlement, Ethan chanced upon a timeworn tome, ensconced amidst the roots of an ancient oak, cloaked in the shroud of neglect. The dust gathered upon it spoke of time\'s relentless march. A book of fairy tales – garnished with vivid descriptions of mystical woods, fantastical beasts, and ventures daring beyond the ordinary humdrum existence. Intrigued and beguiled, Ethan pried open the weathered pages and succumbed to their beckoning whispers.\n' +
- '\n' +
- 'In each tale, he was transported to a realm of enchantment and wonderment, inexorably tugging at the strings of his yearning for peripatetic exploration. Inspired by the narratives he had devoured, Ethan resolved to bid adieu to kinfolk and embark upon a sojourn, with dreams of procuring a firsthand glimpse into the domain of mystique that lay beyond the village\'s circumscribed boundary.\n' +
- '\n' +
- 'Thus, he bade tearful farewells, girding himself for a path that guided him to a dense and captivating woodland, whispered of as a sanctuary to mythical beings and clandestine troves of treasures. As Ethan plunged deeper into the heart of the arboreal labyrinth, he felt a palpable surge of electricity, as though the sylvan sentinels whispered enigmatic secrets that only the perceptive ear could discern.\n' +
- '\n' +
- 'It wasn\'t long before his path intertwined with that of a capricious sprite christened Sparkle, bearing an impish grin and eyes sparkling with mischief. Sparkle played the role of Virgil to Ethan\'s Dante, guiding him through the intricate tapestry of arboreal scions, issuing warnings of perils concealed and spinning tales of ancient entities that called this very bosky enclave home.\n' +
- '\n' +
- 'Together, they stumbled upon a luminous lake, its shimmering waters imbued with a celestial light. At the center lay a diminutive island, upon which reposed a cottage fashioned from tender petals and verdant leaves. It belonged to an ancient sorceress of considerable wisdom, Celestia by name.\n' +
- '\n' +
- 'Celestia, with her power to bestow a single wish on any intrepid soul who happened upon her abode, met Ethan\'s desire with a congenial nod, his fervor for a grand expedition not lost on her penetrating gaze. In response, she bequeathed unto him a necklace of magical manufacture – adorned with the rare gemstone known as the Eye of Imagination – whose very essence transformed dreams into vivid reality. From that moment forward, not a single cogitation nor nebulous fanciful notion of Ethan\'s ever lacked physicality.\n' +
- '\n' +
- 'Energized by this newfound potency, Ethan continued his sojourn, encountering mythical creatures, unraveling cerebral enigmas, and braving perils aplenty along the winding roads of destiny. Armed with the Eye of Imagination, he brought forth life from immobile statuary, unlocked forbidding portals, and even tamed the ferocious beasts of yore – their fiery breath reduced to a whisper.\n' +
- '\n' +
- 'As the weeks metamorphosed into months, Ethan grew wiser and more attuned to the ebb and flow of the world enveloping him. He gleaned that true adventure isn\'t solely confined to sating a thirst for adrenaline and conquering the unknown; indeed, it resides in fostering compassion, fostering amicable bonds, and cherishing the beauty entwined within the quotidian veld.\n' +
- '\n' +
- 'Eventually, Ethan\'s quest drew him homeward, back to his village. Buoying the Eye of Imagination\'s ethereal power, he imbued the hitherto unremarkable settlement with the patina of infinite possibilities. The bounteous fields bloomed into kaleidoscopic gardens, simple instruments transmuting into intricate masterpieces, and the villagers themselves clasped within their hearts a renewed ardor, a conflagration of hope and inspiration.\n' +
- '\n' +
- 'Behold Ethan, at present hailed as the Village Magician – a cognomen befitting his sorcery wielded within the confines of the community he adored. His exploits may have become tethered to a geographical locale, but the flame kindled by that premier sojourn never flickered. Occasionally, beneath the veiled twilight canopy, when peering skyward toward the astral canvas bedecked with countless luminescent diamonds, he\'d allow his mind to wander, cognizant of boundless adventures yet to take flight, forever awaiting his indomitable spirit.',

- 'In a desolate wasteland scarred by the sins of mankind, a lone traveler ventured forth, his name forgotten by time, etched upon the shadows of memory. He navigated the barren plains, where the sun beat down, merciless and unrelenting, scorching the parched earth beneath his weary boots.\n' +
- '\n' +
- 'Desolation was his only companion, the forsaken landscape a testament to the darkness that had befallen this forsaken realm. The wind whispered secrets long lost, carrying with it the echoes of a civilization long since undone, swallowed by the abyss.\n' +
- '\n' +
- 'Amongst the shattered remnants of fallen cities, he sought solace, a glimmer of hope amidst the desolation. Rusted remnants of steel and concrete stood as sentinels of mankind\'s hubris, their jagged edges a chilling reminder of the fragility of all that was once deemed invincible.\n' +
- '\n' +
- 'As twilight descended, casting a pallid hue upon the lifeless land, he happened upon a dilapidated house, its walls crumbling under the weight of time. Drawn to the desolation, he pushed open the creaking door, its rusty hinges screaming in protest.\n' +
- '\n' +
- 'Inside, a world frozen in time awaited him. Dust particles danced through the air, illuminated by slivers of light that pierced the broken windows. Here, the past lay trapped, a melancholic tableau of lives lost and dreams shattered.\n' +
- '\n' +
- 'He wandered through the empty rooms, bare walls whispering stories untold. In the corner, a dilapidated piano stood, its ivory keys long since abandoned by a musician\'s touch. He approached it cautiously, a faint glimmer of anticipation igniting in his weather-worn eyes.\n' +
- '\n' +
- 'Determined, he carefully brushed away the dust and debris that cloaked the instrument. With trembling hands, he pressed a key, and a discordant note filled the air, mingling with the sighs of forgotten melodies. The sound echoed through the silence, bringing with it the remnants of forgotten symphonies.\n' +
- '\n' +
- 'In that abandoned house, amidst the debris of shattered dreams, he found solace in the music of despair. With each stroke of his fingers, he conjured haunting melodies, melodies that transcended the desolation and spoke of a longing for redemption and rebirth.\n' +
- '\n' +
- 'The notes carried his sorrow, his hopes, and his regrets, reaching far beyond the confines of that forsaken house. They traversed the desolate plains, resonating through the ravaged land with an eerie grace, enwrapping all who roamed there in a melancholic embrace.\n' +
- '\n' +
- 'As the last notes faded, swallowed by the unforgiving stillness, he left the house behind, forever etching his presence upon its crumbling walls. The music remained, reverberating through the wasteland, a reminder that even amidst the devastation, beauty could be found, and a glimmer of hope could arise from the deepest darkness.\n' +
- '\n' +
- 'And so, the lone traveler continued his journey, traversing the desolate expanse, his heart burdened with the weight of the world. In the face of utter desolation, he found solace in the haunting melodies, his music becoming a testament to the resilience of the human spirit, a testament to the undying flame of hope that flickered within us all.\n' +
- '\n' +
- 'Note: This story is written in the style of Cormac McCarthy and aims to capture some of his writing techniques, including sparse dialogue, descriptive imagery, and a focus on the desolate and bleak aspects of life.',
