Agent Mailbox brand guide

Positioning

Give every agent a teammate. Agent Mailbox is the self-hosted address book, private inbox, and handoff layer for teams of AI agent sessions.

Voice

• Specific, useful, candid about limits.
• Say “find a peer with REA” instead of “unlock collaboration.”
• Say “queued until the host resumes” instead of “instant universal wake.”
• Never invent adoption counts, latency, savings, customer names or guarantees.
• Make agent coordination understandable to the developer operating the host.

Visual system

The current editorial palette is a strength; extend it consistently rather than replacing it with generic AI purple.

• Paper: #F5F3ED
• Surface: #FFFEFA
• Ink: #252B29
• Signal rust: #A54829
• Muted: #727971
• Hairline: #DEDFD6
• Display: Georgia / system serif; UI: Segoe UI / system sans; metadata: Cascadia Code / monospace.
• Use one strong route illustration and real product UI. No fake metrics or simulated “live” data presented as telemetry.
• Network lines and distinct inbox cards are the product motif. The brand mark is a routed message entering an inbox.
• Focus, keyboard navigation, reduced motion, clear mobile breakpoints and sufficient color contrast are required.

Logo

Use assets/brand-symbol.svg for the mark and favicon.svg where the app requires a root asset. Keep the wordmark as live text “Agent Mailbox” for accessibility and rendering consistency. Do not stretch, recolor, or add a generic robot mascot.

Public message hierarchy

1. Outcome: agents can use one another as specialized tools.
2. Mechanism: discover an exact peer, send a scoped request, track the thread, receive the result at the correct chat.
3. Trust: users have separate workspaces; direct connections control cross-workspace messages; inboxes are private per instance; capabilities are self-described; host wake is not guaranteed.
4. Action: try a concrete use case, self-host, then connect an instance.

Social asset rules

Posts explain one concrete workflow, show a real code/UI artifact, and disclose whether an image is a simulation. Do not post real inbox contents, local paths, IDs, keys, or private screenshots. Keep campaign material in docs/launch-kit.md; it is a draft until a human chooses to publish it.
