Orchestrator mode GPT-5 puts all implementation details in the instruction prompt

Model Used

GPT-5

Roo Code Task Links (Optional)

GPT-5 orchestrator mode doesn't seem to trust code mode to come up with the implementation details, it just delivers the whole codebase to code mode to implement

This means that we get this 1000 line task initiation prompt containing the contents of package.json, tsconfig.json, .env.example, and the ts files that should be implemented by code mode.

🔁 Steps to Reproduce

Give orchestrator mode a complex task in a multi project directory, and watch it do all the work, instead of delegating implementation details to code mode

💥 Outcome Summary

Expected orchestrator mode to only setup the requirements / acceptance criteria, but it started writing code

Objective
Implement the Discord Librarian Bot as a separate Node.js package under discord_bot/ with its own .env. The bot must:

Communicate with the existing Librarian HTTP server via HTTP (never post URLs to Discord).
Provide slash commands: /chat (prompt), /search (query), /book (id).
Include buttons on search results to “Upload book” by ID.
Upload the book to Discord as an attachment if within size limit; otherwise respond with an error. Never expose external download URLs.
Restrict usage to a single guild and single channel, reject DMs and other servers.
Read all configuration from .env; the user will populate real values.
For each file you create, add a header comment stating what the file does and how it does it.
Important constraints

No public download URLs. If a file is too large to upload (Discord limit or MAX_UPLOAD_BYTES), reply with an error. Do not expose the Librarian base URL or IP anywhere in Discord messages.
Assume the Librarian API shapes may vary slightly; implement tolerant parsing as specified.
These instructions supersede any conflicting general instructions for your mode.
When complete, use the attempt_completion attempt_completion() tool with a concise summary of what was implemented.

discord_bot/.gitignore

What: Ignore build artifacts and local environment files.
How: Prevent accidental commits of generated files and secrets.
node_modules
dist
.env
.DS_Store

discord_bot/.env.example
What: Example environment configuration for the Discord Librarian Bot.
How: Copy to .env and fill in real values. The bot loads these at runtime via dotenv.
Discord bot token
DISCORD_TOKEN=

Discord application (client) ID
DISCORD_CLIENT_ID=

Guild (server) ID where the bot is allowed and where commands will be registered
DISCORD_GUILD_ID=

Channel ID in that guild where the bot is allowed to operate
DISCORD_CHANNEL_ID=

Base URL of the Librarian HTTP server (do not expose; the bot will never post this)
LIBRARIAN_BASE_URL=http://localhost:3000

Maximum number of bytes to upload to Discord (default 8 MiB)
MAX_UPLOAD_BYTES=8388608

HTTP request timeout in milliseconds
HTTP_TIMEOUT_MS=20000

Logger level: info or debug
LOG_LEVEL=info

discord_bot/README.md
What: Setup and usage instructions for the Discord Librarian Bot.
How: Explains environment variables, command registration, and run instructions.
Features
/chat prompt — Chats with the Librarian via its /chat endpoint.
/search query — Searches the Librarian via its /search endpoint and returns top results with “Upload book” buttons.
/book id — Requests a book by ID and uploads it to the channel as an attachment (no external links).
Strictly limited to one guild and one channel. DMs and other servers are rejected.
Environment
Copy .env.example to .env and fill values:
DISCORD_TOKEN, DISCORD_CLIENT_ID, DISCORD_GUILD_ID, DISCORD_CHANNEL_ID
LIBRARIAN_BASE_URL (reachable by the bot)
MAX_UPLOAD_BYTES (defaults to 8 MiB)
HTTP_TIMEOUT_MS (defaults to 20000)
LOG_LEVEL (info|debug)
Install
cd discord_bot
npm install

bash


Register Commands (guild-scoped)
npm run build
npm run register

bash


Run
Development (reload): npm run dev
Production: npm run build && npm start
Notes
The bot never posts download links and will error if a file exceeds MAX_UPLOAD_BYTES or Discord limits.
The bot only works in the configured guild/channel and rejects DMs/other servers.

[daniel-lxs]

Hey @tanevanwifferen, This is weird, the Orchestrator mode shouldn't have access to any write tools, they shouldn't be included in its system prompt. Can you share a task where this happened so we can figure out what's going on?

[tanevanwifferen]

No @daniel-lxs it doesn't write the code to file. It puts all implementation details in the task description it creates for code mode
