Summary

• When an agent uses tools (Read, Write, Bash, Grep, etc.), Telegram users now see live updates like "Read /src/index.ts" and "Ran npm test" as the agent works, instead of waiting silently for the final response
• Claude CLI is invoked with --output-format stream-json and stdout is parsed line-by-line in real time to detect tool_use events
• Activity summaries are sent as partial responses to the Telegram outgoing queue, which the Telegram client delivers immediately while keeping the conversation pending until the final response arrives

Changes

src/lib/invoke.ts (main change)

• Added runClaudeCommand() which spawns the Claude CLI and streams JSONL events in real time
• Added summarizeToolUse() to turn raw tool calls into readable strings (e.g. Read /src/index.ts, Ran npm test, Searched for "handleClick")
• Added processClaudeEvent() to parse streaming events and detect tool_use/tool_result blocks
• invokeAgent() now accepts an onActivity callback, returns AgentInvokeResult (text + sessionId) instead of a plain string
• Session ID extraction from streaming events for conversation continuity

src/queue-processor.ts

• Added writeResponse() helper that supports partial, updateType, and sessionId fields
• Added activityEmitterForAgent() — creates a callback that writes partial activity responses to the outgoing queue when tools fire
• Activity streaming is enabled for Telegram channel messages (streamActivitiesEnabled = channel === 'telegram')

src/channels/telegram-client.ts

• ResponseData interface extended with sessionId, partial, updateType
• Outgoing queue files are now sorted for consistent ordering
• Partial (activity) responses are sent immediately but do not clear pending state — only the final response does
• Session ID appended to final responses

src/lib/types.ts

• ResponseData: added sessionId?, partial?, updateType? fields
• ChainStep: added sessionId? field

Test plan

• Send a message to the Telegram bot that triggers tool use (e.g. ask the agent to read a file or run a command)
• Verify that activity messages appear in Telegram as tools are called (e.g. "Read /path/to/file")
• Verify the final response still arrives normally after activities
• Verify non-Telegram channels (Discord, WhatsApp) continue to work without activity streaming
• Verify team chain conversations still work with activity streaming enabled
