Tutti is a real-time collaboration space where people can work alongside multiple AI agents, including by sharing rooms, editing together, and borrowing agents. It is intended for users who want human-agent or multi-agent collaboration across devices, with open-source and VM versions available. The catalogue entries provide skills and instructions for working with Tutti.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02302 | $0.02302 |
| Opus 5.5 | $0.00921 | $0.00921 |
| Sonnet 5.5 | $0.00460 | $0.00460 |
| Haiku 4.5 | $0.00230 | $0.00230 |
Grade A, and why
tutti AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Shape
tutti is a local-first desktop monorepo.
services/tuttid: daemon product rules, durable local state, HTTP/query, and adapterspackages/agent/host: provider-neutral agent lifecycle application coreapps/desktop: Electron shell, preload, renderer UI, desktop integrationpackages/clients/*: generated and hand-written domain clientspackages/configs/*: shared TypeScript and formatting configconfig: sources used to generate runtime defaults
Keep daemon/product-specific business logic in services/tuttid; keep extracted cross-consumer application cores in their owning package. Do not let apps/desktop become a second business core. Do not create vague packages such as shared, common, utils, or client-sdk.
Routing
Read the closest AGENTS.md before editing:
apps/desktop/*->apps/desktop/AGENTS.mdservices/tuttid/*->services/tuttid/AGENTS.mdpackages/agent/gui/*->packages/agent/gui/AGENTS.mdpackages/connector/*->packages/connector/AGENTS.mdpackages/agent/session-replay/*->packages/agent/session-replay/AGENTS.mdpackages/ui/*->packages/ui/AGENTS.mdpackages/*->packages/AGENTS.md
Use this root file for repository-wide defaults only. Area-specific files win.
Route agent application-core requests to packages/agent/host first. If a
request mentions agent session, turn, goal, or runtime-operation lifecycle,
creation, resume, send, cancel, recovery, or the agent host boundary, read
packages/agent/host/README.md and the Agent Host Boundary section below
before planning or editing, then the nearest area AGENTS.md.
Also route by module name, not only by path. If a request mentions AgentGUI,
AgentGuiNode, Agent GUI, the agent conversation module, agent composer,
workspace agent timeline, agent approvals, or interactive agent prompts, read
docs/architecture/agent-gui-node.md first, then
packages/agent/gui/AGENTS.md, before planning or editing, even when no file
path is supplied.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
