Move mattermost channel implementation from core to extensions/mattermost plugin. Extract config schema, group mentions, normalize utilities, and all mattermost-specific logic (accounts, client, monitor, probe, send) into the extension. Update imports to use plugin SDK and local modules. Add channel metadata directly in plugin definition instead of using getChatChannelMeta. Update package.json with channel and install configuration.
Slack's files.uploadV2 API no longer supports the filetype field and logs
deprecation warnings when it's included. Slack auto-detects the file type
from the file content, so this field is unnecessary.
This removes the warning:
[WARN] web-api:WebClient filetype is no longer a supported field in files.uploadV2.
The message tool accepts path and filePath parameters in its schema,
but these were never converted to mediaUrl, causing local files to
be ignored when sending messages.
Changes:
- src/agents/tools/message-tool.ts: Convert path/filePath to media with file:// URL
- src/infra/outbound/message-action-runner.ts: Allow hydrateSendAttachmentParams for "send" action
Fixes issue where local audio files (and other media) couldn't be sent
via the message tool with the path parameter.
Users can now use:
message({ path: "/tmp/file.ogg" })
message({ filePath: "/tmp/file.ogg" })
Adds the ability to customize the assistant's name and avatar in the Web UI.
Configuration options:
- config.ui.assistant.name: Custom name (replaces 'Assistant')
- config.ui.assistant.avatar: Emoji or letter for avatar (replaces 'A')
Also reads from workspace IDENTITY.md as fallback:
- Name: field sets the assistant name
- Emoji: field sets the avatar
Priority: config > IDENTITY.md > defaults
Closes#1383
When creating exec tools via chat/Discord, agentId was not passed,
causing allowlist lookup to use 'default' key instead of 'main'.
User's allowlist entries in agents.main were never matched.
Now derives agentId from sessionKey if not explicitly provided,
ensuring correct allowlist lookup for all exec paths.
- Add avatar field to IdentityConfig type
- Add avatar parsing in AgentIdentity from IDENTITY.md
- Add renderAvatar support for image avatars in webchat
- Add CSS styling for image avatars
Users can now configure a custom avatar for the assistant in the webchat
by setting 'identity.avatar' in the agent config or adding 'Avatar: path'
to IDENTITY.md. The avatar can be served from the assets folder.
Closes #TBD
TypeBox Type.Optional(Type.String()) accepts string|undefined but NOT null.
Discord exec was failing with 'resolvedPath must be string' because callers
passed null explicitly. Web UI worked because it skipped the approval request.
Fixes exec approval validation error in Discord-triggered sessions.
- Add ToolCallIdMode type ('standard' | 'strict') for provider compatibility
- Standard mode (default): allows [a-zA-Z0-9_-] for readable session logs
- Strict mode: only [a-zA-Z0-9] for Mistral via OpenRouter
- Update sanitizeSessionMessagesImages to accept toolCallIdMode option
- Export ToolCallIdMode from pi-embedded-helpers barrel
Addresses review feedback on PR #1372 about readability.
Some providers like Mistral via OpenRouter require strictly alphanumeric
tool call IDs. The error message indicates: "Tool call id was
whatsapp_login_1768799841527_1 but must be a-z, A-Z, 0-9, with a length
of 9."
Changes:
- Update sanitizeToolCallId to strip all non-alphanumeric characters
(previously allowed underscores and hyphens)
- Update makeUniqueToolId to use alphanumeric suffixes (x2, x3, etc.)
instead of underscores
- Update isValidCloudCodeAssistToolId to validate alphanumeric-only IDs
- Update tests to reflect stricter sanitization
Fixes#1359
