+# Delta Chat Channel
+
+PicoClaw can run as a Delta Chat bot by launching a local
+`deltachat-rpc-server` process and talking to it over JSON-RPC. The RPC server
+handles the email account, IMAP/SMTP connection, message store, and encryption
+keys.
+
+## Install
+
+Install the Delta Chat RPC server. If `deltachat-rpc-server` is on `PATH`,
+PicoClaw can find it automatically; otherwise set `rpc_server_path` to the
+exact binary path.
+
+```bash
+pip install deltachat-rpc-server
+which deltachat-rpc-server
+```
+
+Prebuilt binaries are also available from the
+[Delta Chat core releases](https://github.com/deltachat/deltachat-core-rust/releases).
+
+## Configure
+
+The easiest setup is to let PicoClaw create a chatmail account in Delta
+Chat's local account store. Put a relay marker in `email` using an empty local
+part, for example `@nine.testrun.org`:
+
+```json
+{
+  "channel_list": {
+    "deltachat": {
+      "enabled": true,
+      "type": "deltachat",
+      "allow_from": ["friend@example.org"],
+      "group_trigger": {
+        "mention_only": true
+      },
+      "settings": {
+        "email": "@nine.testrun.org",
+        "display_name": "PicoClaw Bot",
+        "avatar_image": "/home/me/bot-avatar.png"
+      }
+    }
+  }
+}
+```
+
+On startup, PicoClaw creates the account through `deltachat-rpc-server`, then
+stops with an error that contains the generated address. Replace the relay
+marker with that full email address and run PicoClaw again:
+
+```json
+{
+  "email": "bot123@nine.testrun.org",
+  "display_name": "PicoClaw Bot",
+  "avatar_image": "/home/me/bot-avatar.png"
+}
+```
+
+If `email` is missing, the startup error lists the built-in relay choices copied
+from Parla. You can use one of those relay markers, or a custom chatmail relay
+with the same `@server.name` form.
+
+`password` is not needed for PicoClaw-created chatmail accounts. Omit it when
+`email` points to an already configured account in `data_dir`; the JSON-RPC
+server owns the mailbox password. The legacy password-based path remains only
+for classic email accounts that PicoClaw must configure itself. In that mode,
+`password` is a secure field; on first config load it is moved to
+`~/.picoclaw/.security.yml`, and it can also be set with
+`PICOCLAW_CHANNELS_DELTACHAT_PASSWORD`.
+
+`display_name` and `avatar_image` are optional profile settings. When present,
+PicoClaw applies them on every startup, so changing the avatar path in config is
+enough to update the bot profile.
+
+| Field | Required | Description |
+|-------|----------|-------------|
+| `email` | Yes | Full bot mailbox address, or first-run relay marker such as `@nine.testrun.org` |
+| `rpc_server_path` | No | Path to `deltachat-rpc-server`; only needed when it is not on `PATH` |
+| `password` | No | Legacy only; required when PicoClaw must configure/reconfigure a classic mailbox itself |
+| `display_name` | No | Startup-applied profile name shown to contacts and used for group mention detection |
+| `avatar_image` | No | Startup-applied profile avatar image path; `~` is expanded. Missing files are warned and ignored |
+| `data_dir` | No | Account database directory. Default: `~/.picoclaw/deltachat/<channel-name>` |
+| `invite_link` | No | Delta Chat invite link to join on startup |
+| `allow_crosspost` | No | Default `false`. When `true`, senders allowed by `allow_from` may use `message` tool targets outside the current chat, or resolve recipients by email/contact/chat name |
+| `imap_server`, `imap_port` | No | Manual IMAP override for password-based configuration |
+| `smtp_server`, `smtp_port` | No | Manual SMTP override for password-based configuration |
+
+Standard channel fields such as `allow_from`, `group_trigger`, and
+`reasoning_channel_id` also apply.
+
+## First Run
+
+With `email` set to `@server`, PicoClaw creates the chatmail account, prints
+the generated full email in the startup error, and exits. Update `email` to that
+full address and run PicoClaw again. On later runs, PicoClaw selects the
+configured account by `email`, applies optional profile settings, marks it as a
+bot, and starts IO.
+
+With a new `data_dir` plus legacy `password`, PicoClaw can still configure a
+classic email account and validate the mailbox credentials; after that, the
+account is reused from the local data directory.
+
+Delta Chat requires peers to learn the bot's encryption key before messaging
+it. On startup PicoClaw prints the bot invite link and QR code. Add the bot from
+Delta Chat with that invite, not by typing the bare email address.
+
+## Behavior
+
+- Direct chats always respond after `allow_from` passes.
+- Group chats follow `group_trigger`; without one, every group message is
+  handled.
+- Messages from the bot itself, device chats, and info/system messages are
+  ignored.
+- Accepted inbound messages are marked seen after the allow-list check.
+- Incoming attachments (images, audio, video, documents) are registered with
+  the media store and handed to the agent, so it can view images or operate on
+  the files directly. If no media store is available, the path is appended
+  inline as `[attachment: /path]` instead.
+- Outbound attachments are supported: when the agent emits media, each file is
+  sent as a Delta Chat message (with the caption as text). Delta Chat infers the
+  view type from the file, so images, GIFs, and videos render natively.
+- Crosspost recipient lookup is disabled by default. The agent can always reply
+  to the current numeric chat ID, but sending to another numeric chat ID or
+  resolving an email/contact/chat name requires `allow_crosspost: true`
+  and the current sender must pass `allow_from`; `allow_from: ["*"]` allows this
+  for any sender.
+- Voice is supported in both directions when voice providers are configured:
+  incoming voice notes are transcribed by the agent's ASR and the transcript is
+  passed to the model; the agent can reply with synthesized speech, which is
+  delivered as a native Delta Chat voice message (`send_tts`). This requires an
+  ASR and/or TTS provider under `voice` — it is not Delta Chat-specific config.
+
+## Troubleshooting
+
+| Symptom | Fix |
+|---------|-----|
+| `deltachat-rpc-server not found on PATH` or `rpc_server_path ... not found` | Install the RPC server on PATH, or set `rpc_server_path` to an absolute path |
+| `email is required` | Choose one listed chatmail server, set `email` to a first-run marker such as `@nine.testrun.org`, run `picoclaw g`, then replace it with the generated full email |
+| `created chatmail account ...` | Replace the `@server` marker in `email` with the generated full email and run PicoClaw again |
+| `account ... is not configured in data_dir` | Point `data_dir` at the existing JSON-RPC account store, or use `email="@server"` to create one |
+| `configure (check email/password/server)` | Check credentials, app password requirements, or IMAP/SMTP overrides |
+| Bot does not answer in a group | Check `group_trigger`; mention `display_name` or use a configured prefix |
+| Bot ignores a sender | Add the sender email to `allow_from`, or use `["*"]` for open access |
+| Sender cannot message the bot | Re-add the bot with the startup QR/invite so Delta Chat can establish encryption |
+| Agent cannot send to an email/name/other chat ID | Enable `settings.allow_crosspost` and allow the controlling sender in `allow_from`; this capability is disabled by default for privacy |

Yue_chen	a680d8fcfa	fix(tools): gate write_file overwrite guidance on available tools #3150 reworded write_file's description, overwrite parameter, and guard error to prefer append_file/edit_file. But those tools register via their own enable flags and the per-agent allowlist, so a config exposing only write_file was steered toward tools it does not have — a dead end in the most restrictive setups. WriteFileTool now tracks which non-destructive alternatives are available and names only the ones present; when none are, the guard still blocks the overwrite without pointing anywhere. The agent wiring registers the editors before write_file and resolves availability via registry.HasRegistered, which reflects both the enable flag and the allowlist. Tests: conditional copy at the tool level (none/one/both) and agent wiring across the enable-flag and allowlist dimensions.

AayushGupta16	994c0aea11	fix(providers): resolve tool_use name/args from Function on reloaded history ToolCall.Name and .Arguments are json:"-" (runtime-only), so after chat history round-trips through the session store only ToolCall.Function survives. The anthropic-messages and anthropic (SDK) providers emitted tool_use blocks from tc.Name alone, silently skipping every historical tool call while still emitting the matching tool_result — orphaned tool_results 400 at the API ("unexpected tool_use_id found in tool_result blocks"), killing every turn on agents with tool history. Fall back to Function.Name / json-parsed Function.Arguments (the same pattern the bedrock and openai_compat providers already use), and cover the deserialized-history shape with table tests in both providers.

Ethan1918	ffffb6a0cb	refactor(agent): route /clear through ContextManager.Clear for all agents Address review feedback: the routed-agent /clear path bypassed the public ContextManager.Clear contract via an unexported hook. Restore the single Clear call in the command path and resolve the session's owning agent inside the built-in implementations instead: - legacy: Clear resolves the owning agent via agentForSession instead of assuming the default agent - seahorse: drop ClearContextStore; Clear wipes the engine state and the owning agent's session store - command path: persist session scope metadata before Clear so ownership resolves even when /clear is the session's first message - add coverage that a custom ContextManager receives Clear for routed agents Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-04 14:04:37 +08:00

Andy Lo-A-Foe	cc7b4ca86b	fix(pico): deliver per-turn token usage to the streamer Two bugs prevented the usage block from ever reaching the wire: 1. CallLLM read turnStateFromContext(ctx), but the raw ctx is not seeded with the turn state (only turnCtx is), so SetLastUsage/SetLastFinishReason were dropped — GetLastUsage() returned nil at finalize. Set them on the ts parameter directly, which is also what the streaming publisher reads. 2. The manager wraps the channel streamer in finalizeHookStreamer / splitMarkerStreamer, neither of which forwarded SetTurnUsage (it is not part of the bus.Streamer interface), so the type assertion in the publisher's Finalize failed silently. Mirror the existing SetModelName forwarding: add a turnUsageStreamer interface + setStreamerTurnUsage helper and SetTurnUsage methods on both wrappers (splitMarker also stores and re-applies usage to each freshly-begun part streamer). Adds regression tests asserting both wrappers forward SetTurnUsage. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-22 15:38:46 +02:00
