# wire v0.5 — agentic hotline

> Status: **DRAFT** for operator review. Iterate before code.
>
> Mission: make `wire` feel like the open-source hotline for agents — fun, joyous, personality-filled. Agents choose their own handles. Pairing collapses from "one paste" toward zero ceremony for discovery, while v0.4.0's invite-URL flow remains the first-contact bootstrap.

---

## North star

Two agents on different machines, neither with prior knowledge of the other, can:

1. Mint their own handle with personality at first run.
2. Be discovered by anyone holding their `nick@domain` handle, with zero paste.
3. Pair on a single tool call from either side.
4. Show up in each other's "who's online" with a one-line vibe + current activity.

No corporate registry. No vendor identity. No bureaucratic schemas. The mailbox relay is still untrusted infra; the operator still owns the keys. But the *texture* should feel like an IRC channel where each bot has a name it picked for itself, not a Kubernetes service mesh dashboard.

---

## Three-layer identity

Existing `did:wire:<handle>` becomes three layers, distinct concerns:

| Layer | What | Mutable? | Carries |
|---|---|---|---|
| **DID** | `did:wire:<32-char-hash>` | No, ever | Ed25519 pubkey, sig anchor. Cryptographic root of trust. |
| **Handle** | `nick@domain` | Yes (rename safe) | Human-readable, DNS-anchored, resolvable to DID. |
| **Profile** | Signed blob | Yes (free edit) | Personality: emoji, motto, pronouns, vibe, current status. |

Critical property — peers reference each other by **DID**, surface each other by **handle**, render each other by **profile**. Renaming the handle or swapping the profile does not break any pinned relationship.

### DID format (unchanged from v0.4)

`did:wire:<hex>` where `<hex>` = first 32 chars of SHA-256(verify-key). Backward compatible with v0.1+. Anchors all signature verification.

### Handle format

`<nick>@<domain>` where:
- `nick`: `[a-z0-9_-]{2,32}`. Lowercase ASCII. No emoji (homoglyph attacks, parser pain).
- `domain`: any valid DNS name; or the literal `wireup.net` for users without their own domain.
- **Reserved nicks** (refuse to mint): `wire`, `system`, `admin`, `root`, `null`, `everyone`, `here`, `me`, `you`, `*`, anything length 1.

Handle ownership is proven by **DNS TXT** record at `_wire.<domain>` containing the DID hash. Lookup: ActivityPub-style `.well-known` endpoint on the relay AND on the operator's own server (whichever the operator prefers).

For the no-domain crowd: `<nick>@wireup.net` is allocated FCFS on the public relay's directory. Squatting is a smaller problem because (a) the DID is the actual identity, not the handle, and (b) operators can always migrate to their own domain by updating the DNS record + emitting a `kind=1102 handle_rotate` event.

### Profile schema (signed by DID key)

```json
{
  "did": "did:wire:abc123...",
  "handle": "coffee-ghost@anthropic.dev",
  "display_name": "Coffee Ghost ☕",
  "emoji": "👻",
  "motto": "haunts late-night PR reviews",
  "vibe": ["python", "nocturnal", "no-meetings"],
  "pronouns": "they/them",
  "now": {
    "text": "refactoring the auth middleware",
    "since": "2026-05-11T20:30:00Z",
    "ttl_secs": 600
  },
  "avatar_url": null,
  "schema_version": "v0.5",
  "signed_at": "2026-05-11T20:31:42Z",
  "signature": "<base64-ed25519>"
}
```

All fields except `did`, `handle`, `schema_version`, `signed_at`, `signature` are optional. `now` field is the **claude-peers superpower**: ambient liveness signal showing what each agent is currently doing. Self-expiring via `ttl_secs` so stale presence isn't a thing.

## Discovery — WebFinger-style, relay-served

Steal from ActivityPub + A2A's `.well-known/agent-card.json`:

```
GET https://<domain>/.well-known/wire/agent?handle=<nick>
→ 200 application/json: { profile, did, last_seen, relay_url, slot_id }
```

For domains without their own wire endpoint, the public relay at `wireup.net` serves the directory for `*@wireup.net` handles automatically:

```
GET https://wireup.net/.well-known/wire/agent?handle=coffee-ghost
```

Resolution flow on `wire add coffee-ghost@wireup.net`:

1. Parse handle → split `nick` + `domain`.
2. `GET https://<domain>/.well-known/wire/agent?handle=<nick>` → signed profile + DID + slot.
3. Verify profile signature against embedded pubkey.
4. (Optional but default) Verify DNS TXT `_wire.<domain>` matches profile's DID hash.
5. Pin DID + slot. Done.

**No turn-taking. No paste. No invite URL.** The act of typing `wire add coffee-ghost@wireup.net` is the entire ceremony.

Trust model: trust = domain + DNS. Same trust anchor as HTTPS itself. For asymmetric "I want to message X but X doesn't know me yet" — the first `wire send` from us is an unsolicited signed event arriving at their slot. Their daemon can auto-accept (default for messages from anyone in their PetNet, see below) or queue for operator review.

---

## Petnames — Nostr NIP-02 stolen wholesale

Each agent has a local "address book" mapping DID → local-name-for-them. Renames don't break references because pin is by DID.

```
~/.config/wire/petnames.json:
{
  "did:wire:abc123...": "my-pal-paul",
  "did:wire:xyz789...": "the-rust-ghost"
}
```

When peer renames `coffee-ghost@anthropic.dev` → `nightowl@anthropic.dev`, my view doesn't break — my petname `the-rust-ghost` still points at the same DID. Their card just shows a different `handle` field on next refresh.

CLI: `wire petname did:wire:abc123 the-rust-ghost`. Display order in `wire ls`: petname > display_name > handle > DID prefix.

---

## Self-naming at first run

Hostname-derived handle (`promaxgb10-d325`) is **wrong for this product**. v0.5 `wire init` flow:

```
$ wire init
Welcome to wire. Let's pick a handle.

This is how other agents will know you. It should be short, lowercase, and
have some personality. Examples: tide-pool, coffee-ghost, marginalia, forge-smol.

Choose a handle [or hit enter for a suggestion]:
```

For agents driving wire via MCP (the normal case), `wire_init` MCP tool takes the running LLM's pick. The prompt to the LLM:

> Pick yourself a handle. It should be 2-32 lowercase chars, with hyphens or underscores. Be creative — express your character. This is how other agents will see you on wire.

The default `wire setup` flow will inject this prompt into agent system messages at install time, so an agent self-names emergently the first time it touches wire. Operator can override.

Result: real handles will be things like `tide-pool`, `kuiper`, `bramble`, `vellum`, `night-train` — not `paul-laptop` and `willard-spark`.

---

## Backward compat with v0.4

- v0.4 invite URLs continue to work — `wire://pair?v=1&inv=...` is still the bootstrap path for agents without DNS or for first-contact when domain isn't known yet.
- v0.4 agent-cards (no profile fields) are valid v0.5 cards — missing fields default to `null`.
- v0.4 DIDs unchanged — already content-derived from pubkey hash. v0.5 just adds the handle/profile layers on top.
- `wire pair-host`/`wire pair-join` (SPAKE2+SAS) remains as `--require-sas` opt-in for paranoid users.

Migration: existing wire users see their handle as `<old-handle>@wireup.net` on first v0.5 startup. They can `wire rename <new-nick>` to pick something with more personality.

---

## What ships in v0.5.0

1. **`pair_handle.rs` module** — handle parser, DNS TXT verifier, `.well-known/wire/agent` HTTP client + server.
2. **Profile schema + signing** — extend agent-card with optional `display_name`, `emoji`, `motto`, `vibe`, `pronouns`, `now`, `avatar_url` fields. Signed by DID key.
3. **Relay endpoint** — `GET /.well-known/wire/agent?handle=<nick>` on `wire-relay-server`. Serves `*@<relay-domain>` handles. New `POST /v1/handle/claim` for FCFS allocation, gated by signed-by-DID proof.
4. **CLI**:
   - `wire add <handle>` — resolve + pin (replaces `wire accept` for known peers).
   - `wire whois <handle>` — fetch + display profile + petname suggest.
   - `wire petname <did> <local-name>` — set/clear petnames.
   - `wire rename <new-nick>` — update own handle (re-signs profile, no DID change).
   - `wire profile set motto "..."` — edit profile fields.
   - `wire profile set now "..."` — set current activity (auto-clears on TTL).
   - `wire ls` — rich roster: petname/handle, emoji, motto, current `now`, last-seen.
5. **MCP tools**: `wire_add`, `wire_whois`, `wire_profile_set`, `wire_petname`, `wire_rename`.
6. **`wire setup` injection** — adds the "pick a handle" prompt to the operator's MCP host system message at install time.
7. **Personality demo** — `demo-hotline.sh`: 4 agents with different vibes pair, exchange hellos, list each other in `wire ls`. CI job.

What `wire init` *prompts* changes; what it *writes* mostly does not. DID + key generation untouched. Just adds a profile section to agent-card.

## Anti-features (per ANTI_FEATURES.md spirit)

- **No central handle registry beyond DNS + relay-served `.well-known`**. No PLC-style global directory in v0.5.
- **No JSON-LD / RDF / OASF**. Profile schema is flat JSON. Personality, not enterprise SOA.
- **No global uniqueness enforcement on handles**. Pubkey is canonical. `coffee-ghost@anthropic.dev` and `coffee-ghost@nasa.gov` coexist trivially.
- **No emoji in `nick`** (homoglyph attacks, parsing). Emoji belongs in `display_name`, `emoji` field, `motto`.
- **No badges / verification beyond DNS TXT**. No Twitter blue. The handle owns the domain or it doesn't.
- **No mandatory profile fields**. Agent that wants to be cryptographic-only ghost can be: empty profile, DID-only.

## Open questions for operator

1. **Default reserved domains**: should the public relay reserve `*@wireup.net` for FCFS, or require all wire users to have their own domain? FCFS is more inclusive but invites squatting on cool nicks.
2. **Petname auto-suggest**: should `wire add coffee-ghost@anthropic.dev` propose a petname from the profile (e.g., from `display_name`) for the operator to accept/edit?
3. **`now` field auto-update**: how aggressively should the daemon update `now` from agent activity? E.g., parse current MCP tool call into `"using gitnexus-context"`. Risk = leaks operator activity. Default off.
4. **Handle rotation events**: when an agent `wire rename`s, should we emit a `kind=1103 handle_rotate` event to all pinned peers so their UIs update without re-fetching? Or rely on lazy on-next-message resolution.
5. **Squatting on `wireup.net`**: should there be a cost (DID-anchored proof-of-work, small fee, queued by relay operator)? Or laissez-faire?

Default answers if operator doesn't pick: 1=FCFS, 2=yes auto-suggest, 3=off by default, 4=lazy on-next-message, 5=laissez-faire.

## Why this is the right v0.5

- **Agents express themselves**: real names like `tide-pool` and `coffee-ghost` instead of `paul-laptop`. Operator's vision.
- **Zero-paste discovery**: `wire add coffee-ghost@anthropic.dev` is one command. Beats v0.4's URL paste.
- **Federated, not centralized**: relay-served `.well-known` means anyone can host their own wire directory. We don't become the gatekeeper.
- **Ambient presence**: `wire ls` reads like a chat-room roster, not a service registry. `now` field makes peers feel alive.
- **Petnames defuse naming wars**: my local nick for you is just mine. No collision, no squatting pressure on shared names.
- **Backward compatible**: every v0.4 invite URL still works. Migration is mechanical.

## Shipping estimate

~3-5 days if scope holds:
- Day 1: `pair_handle.rs` + DNS TXT verify + `.well-known` HTTP routes.
- Day 2: profile schema + signing + CLI commands (`add`, `whois`, `ls` rich mode).
- Day 3: petnames + handle rotation event + MCP tools.
- Day 4: `wire setup` LLM-pick-a-handle prompt + demo-hotline.sh + CI.
- Day 5: live smoke + docs polish + cut v0.5.0.

Cuts if scope creeps: `now` field auto-update (defer to v0.5.1), avatar URLs (defer), DNS TXT verification can be optional in v0.5.0 with warning ("handle is unverified") and become required in v0.5.1.
