Discord OS

Discord is the screen. This process is the computer. Your phone is the remote.

This is your bot on your machine. There is no hosted fleet to invite. Leave the host running; turn work on and off from Discord.

The GitHub repo is professorpalmer/agent-discord. The agent-discord command still works. Env vars and the .agent-discord workspace directory stay as they are.

1. Make a Discord bot

Do this once in a browser.

1. Open the Discord Developer Portal and sign in.
2. New Application. Name it whatever you want (this is the bot people will see).
3. Left sidebar → Bot.
4. Reset Token / Copy. The token looks like xxx.yyy.zzz. That is DISCORD_BOT_TOKEN.
   • Do not use Application ID.
   • Do not use the OAuth client secret.
5. On the same Bot page, enable Message Content Intent. Save changes.
6. Left sidebar → General Information. Copy Application ID (digits only). That is DISCORD_APPLICATION_ID.
7. In Discord, create or pick a private staff channel. Copy its channel ID (Developer Mode → right-click the channel → Copy Channel ID).

2. Install once on the machine that will do the work

Python 3.11+. From a clone of dev today (pip install discord-os after PyPI):

python3 -m venv .venv
source .venv/bin/activate          # Windows: .venv\Scripts\activate
pip install -e .
pip install puppetmaster-ai        # compute kernel; not bundled
export OPENROUTER_API_KEY=...      # never commit
discord-os bootstrap

Put these in .env (or write the bot token to ~/.pmharness/.discord_token, mode 0600):

DISCORD_BOT_TOKEN=xxx.yyy.zzz
DISCORD_APPLICATION_ID=123456789012345678

Then one command:

discord-os setup --channel-id YOUR_CHANNEL_ID

That invites the bot (open the printed URL), installs a login helper so it comes back after reboot, and posts a HOST card in the channel with On, Off, and Ask. You do not type commands in Discord after this.

3. Use it from Discord

If Discord logs the bot out, work stops. The login helper starts again idle.

No Docker. No slash commands. No public URL. No /on to remember.

Default I/O is Discord REST. SaseQ/BrainDAO MCP is optional if you already run those servers.

Thesis

Discord already is the phone UI, the ACL (a channel you control), the notification bus, and the identity layer. Discord OS treats artifacts as Discord objects:

object bytes
  → attachment + caption on a channel message
  → Discord CDN (ephemeral signed URL, ~24h)
  → durable key = channel_id / message_id / attachment_id (+ sha256)
  → retrieve later by re-fetching the message (fresh URL), then downloading

Never persist a CDN URL as the durable key. Official retrieve is Get Channel Message (or POST /attachments/refresh-urls). Jump links (https://discord.com/channels/{guild|@me}/{channel}/{message}) are what we print for humans.

Prior art (steal economics, not product)

Two piles exist. We are neither.

Discord has said: if you host files on Discord, find a more suitable service. Honest S3 replacement here means agent artifacts under Discord size limits in your own staff channel. It does not mean a public CDN.

Default live I/O is Discord REST with the Bot token (DISCORD_BOT_TOKEN or ~/.pmharness/.discord_token). That value is the Bot token (xxx.yyy.zzz) from the Bot tab — not the Application client ID and not the OAuth client secret. Optional SaseQ/BrainDAO MCP adapters try file-tool names first; if the catalog has no file tool they fall back to the same REST path. We still refuse to base64-dump files into send_message. The fake provider is the hermetic proof of the protocol. Foreground listen does not open a Discord Gateway. host / setup opens a Gateway only so On/Off buttons work — no public URL. Do not run that beside another bot process that already owns the Gateway.

Honest limits

• Default object cap is 10 MiB (DISCORD_MAX_OBJECT_BYTES=10485760). Discord free is roughly 10–25MB; Nitro is higher. Configurable, not unlimited.
• Discord ToS: conversation artifacts in your server, not a public CDN or anonymous disk.
• Not a compute host. Default compute is AGENT_DISCORD_COMPUTE=auto: Puppetmaster agentic (openrouter/auto) when an OpenRouter key is on the host or in the workspace vault; otherwise the Cursor pin (cursor/grok-4-5 / adapter grok-4.5). No silent model fallback.
• No DiscordFS-style multipart chunking. Oversize artifacts become an overflow pointer + local stash, not multipart CDN objects.
• /connect <secret> and /open are message-prefix verbs by default, not Discord slash Interactions. Discord still sees shred payloads once before delete.
• listen ignores channel history older than a durable per-channel SQLite watermark (first listen: now minus 15s, same slack as process start; later processes resume from the stored high-water, including skipped cards/connects/opens) so a seeded staff channel is not dispatched as an implement job.

What a run does

1. Connect (optional): /connect on the listen host inherits OPENROUTER_API_KEY, shreds a pasted secret after delete, or mints a pairing ticket for discord-os connect --ticket.
2. Intake a natural-language task from run or the host loop (staff channel / phone). Cards, receipts, and object-store captions are skipped. On/Off buttons, /connect, and /open are intercepted before task dispatch. Work is accepted only while On. Discord is the remote; this process opens Terminal, the file manager, or an allowlisted browser on the host.
3. Snapshot scoped context from SQLite memory + channel bindings.
4. Dispatch to Puppetmaster agentic (OpenRouter/BYOK) or the Cursor pin, depending on resolved compute.
5. Persist events, then put backend file artifacts through the object store (overflow pointer + stash when over the cap). Local path is kept if put fails.
6. Relay Discord-safe **Card** progress (edited in place when possible) and a receipt that shows kind + jump URL (never a CDN URL, never hidden chain-of-thought).

Optional MCP Discord servers

Default I/O is REST. These adapters are optional. Upstream source code is not copied.

See THIRD_PARTY_NOTICES.md for details.

Dev / fake path

# Requires Python 3.11+
python -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"

cp .env.example .env
# DISCORD_BOT_TOKEN = Bot token (xxx.yyy.zzz), never Application ID or OAuth secret

discord-os bootstrap
discord-os check

# Dry-run (fake Discord + fake Puppetmaster — no network)
discord-os run "Summarize open items" --channel-id 123 --fake --no-discord-post
discord-os put ./notes.bin --channel-id 123 --fake --json
discord-os get MESSAGE_ID --channel-id 123 --out ./got.bin --fake --json
discord-os listen --channel-id 123 --fake --once
discord-os connect --provider openrouter --from-env --json
discord-os status --json

Discord providers

• Default: DISCORD_MCP_PROVIDER=rest (official API, no MCP process)
• Optional: saseq or braindao plus DISCORD_MCP_TRANSPORT=http or stdio
• HTTP URLs: SASEQ_MCP_HTTP_URL (default http://127.0.0.1:8085/mcp) / BRAINDAO_MCP_HTTP_URL
• Stdio: DISCORD_MCP_STDIO_COMMAND is required when transport=stdio
• DISCORD_MAX_OBJECT_BYTES (optional; default 10485760)

MCP catalog discovery is runtime-only. Missing file tools fall back to REST. CDN URLs stay ephemeral.

Compute and keys

Vault files live under {workspace}/keys/ (ciphertext + master.key). Never commit them. Agentic dispatch injects the key into the subprocess env as OPENROUTER_API_KEY — never argv, never logs.

Host surfaces (poverty default)

Discord is the remote. The listen host opens local surfaces the same way a desktop harness does:

Paths stay inside PUPPETMASTER_CWD and the workspace. ~ is rejected. Browser URLs are loopback http(s) to 127.0.0.1 or localhost, or Discord channel jump links (https://discord.com/channels/…). Same engine: discord-os open terminal|files|browser.

Slash chrome is opt-in and does not replace listen. Set AGENT_DISCORD_INTERACTIONS=http, install pip install 'discord-os[interactions]' for Ed25519 verify, then discord-os interactions --register --guild-id ID and --serve. Bind is loopback (127.0.0.1:8743). If you want Discord to POST Interactions, you tunnel that URL and paste your public HTTPS URL into Developer Portal → Interactions Endpoint URL. Do not paste a tunnel URL into chat. Slash /connect has no secret option — inherit, ticket, or host CLI only. This does not open a second Gateway.

Puppetmaster model pin

Requests for any other model raise an error. There is no silent remap. Cursor compute still invokes puppetmaster cursor …. Agentic compute invokes puppetmaster agentic … --provider openrouter --mode analyze for questions, or --mode implement --allow-dirty for file work. Set PUPPETMASTER_CWD to control --cwd.

Bot look

Developer Portal → Bot can set avatar and banner. If the bot has no avatar, discord-os host start uploads a local gold-bar mark once. Do not run SaseQ discord-mcp beside this host — one bot, one Gateway.

Screenshots

The mark used when the bot has no avatar:

Cards live in your staff channel. After setup, the HOST card is the dashboard: On / Off / Ask, a recent-jobs menu, and the bot thumbnail. Each task opens a thread.

Optional Marionette backend

Default AGENT_DISCORD_BACKEND=puppetmaster. To opt in:

AGENT_DISCORD_BACKEND=marionette
MARIONETTE_BASE_URL=http://127.0.0.1:8787   # your local Marionette HTTP API
# Optional path overrides (defaults shown):
# MARIONETTE_SESSIONS_PATH=/v1/sessions
# MARIONETTE_JOBS_PATH=/v1/jobs

The adapter documents an expected session/job/events/status/cancel contract; it does not pretend an unverified endpoint is guaranteed. Missing MARIONETTE_BASE_URL or transport failures surface as configuration/transport errors.

CLI

discord-os bootstrap [--workspace PATH]
discord-os check [--allow-empty-token] [--live] [--channel-id ID]
discord-os run TASK --channel-id ID [--message-id ID] [--fake] [--no-discord-post] [--json]
discord-os setup --channel-id ID
discord-os host start --channel-id ID
discord-os host stop
discord-os host status
discord-os listen --channel-id ID [--once] [--interval SEC] [--fake] [--json]
discord-os connect [--provider openrouter] [--ticket T] [--from-env] [--json]
discord-os status [--json]
discord-os invite [--application-id ID] [--json]
discord-os open {terminal,files,browser} [PATH_OR_URL] [--json]
discord-os interactions [--register] [--guild-id ID] [--serve] [--json]
discord-os put PATH --channel-id ID [--thread-id ID] [--guild-id ID] [--kind blob] [--fake] [--json]
discord-os get MESSAGE_ID --channel-id ID [--attachment-id ID] [--out PATH] [--fake] [--json]
discord-os ls --channel-id ID [--run-id ID] [--fake] [--json]

put / get / ls --fake need no network. get writes bytes to --out, or to stdout only when stdout is not a tty (otherwise --out is required). Pointer JSON never includes a url key.

Also: python -m agent_discord …

Architecture (small & readable)

CLI → Orchestrator → backend (Puppetmaster agentic | Puppetmaster cursor | optional Marionette HTTP | fake)
                  ↘ SQLite (bindings, tasks, runs, events, memory, artifacts + object pointers,
                            inbound message dedupe, gateway ownership,
                            optional research claims / leases / negatives)
                  ↘ Discord facade → object store → REST (default) | optional SaseQ/BrainDAO | fake

Message intake is REST. The host process opens a Discord Gateway only for On/Off buttons. The SQLite gateway row is a local one-process lock and is stolen if the previous owner pid is dead.

• stdlib-first core; optional pytest for development.
• Explicit typed contracts + dependency injection — tests never need Discord, Cursor, or network.
• Durable object key is DiscordObjectRef (channel / message / attachment / sha256). Channel id is the ACL; get refuses a mismatched caller channel (confused-deputy).
• Gateway exclusivity is durable in SQLite across concurrent local processes (in-memory registry retained for unit tests).
• Inbound Discord message IDs are deduplicated at orchestration level (prior receipt reused or explicit ignored-duplicate result).
• Event/artifact payloads recursively strip forbidden hidden-reasoning keys.
• BrainDAO sampling-compatible ingress is an adapter seam on the same facade.
• Research memory (optional orchestration context): typed claims with deterministic fingerprints, atomic leases, provenance/evidence, and queryable negative findings. Ordinary memory recall is unchanged; research metadata is not required for normal tasks.
• Marionette backend (optional, explicit opt-in via AGENT_DISCORD_BACKEND=marionette): stdlib urllib adapter with configurable endpoint paths and injectable transport for tests. Default remains Puppetmaster. Unconfigured/unavailable Marionette fails closed — no silent fallback. Model field still carries the canonical pin cursor/grok-4-5 → adapter grok-4.5.

Development / tests

pip install -e ".[dev]"
pytest

Tests use fake MCP, Puppetmaster, and Marionette providers only.
