Headless Claud agents expose TaskCreate/TaskUpdate rather than TodoWrite.
Fold those tool events into the live card checklist, pass real tool names
and inputs through tool-result, and hide Task* noise once the panel is up.
After removing the Typing reaction, add CheckMark on success or CrossMark
on failure so teachers can see completion on the source message without
opening the card.
Defaults and silo env go to 150 turns / 1800s wall clock. Run completion
appends a clear Feishu notice for max-turns, timeout, and other failures
(partial answer kept). Startup process-restart kills notify the bound chat.
Release v0.0.38.
Feishu interactive markdown rejects  without image_key
(error 230099 empty/missing imagekey). Always mask residual image md in
card builders; skip img tags with empty keys; skip inline-code examples;
fetch remote images with a browser UA and without env HTTP_PROXY.
Steer the agent: use  for 图文, send_file only for
downloadable attachments.
Release v0.0.37.
Add a ⛔ 中断 button to live streaming cards; Feishu's native confirm
dialog is the confirmation step, so no extra card round-trip is needed.
- builder.ts: render interrupt action (danger button + confirm) while the
run is live; new `interrupted` flag renders a 已中断 footer instead of
完成/失败 on the complete card.
- streaming-card.ts: finish(text, { interrupted }) threads the flag into
the final patch; overflow cards suppress the button.
- runner.ts: RunRequest gains abortController, passed to the SDK query;
abort surfaces as RunStatus "interrupted" (no error) in the catch.
- trigger.ts: activeRuns registry maps runId → AbortController; onCardAction
resolves the interrupt button, authorizes agent.cancel, aborts the run.
Interrupted runs persist as CANCELED (spec RunState.canceled, terminal →
lock released per ADR-0002).
- authorizer.ts: agent.cancel now consults PermissionSettings.agentCancel
(MANAGE_ONLY/DISABLED) — previously only agentTrigger was honored, but
spec/PermissionGrant deliberately splits these knobs ("谁能触发" ≠
"谁能取消"). Default role remains MANAGE (Capability.normalCancel).
Tests: runner abort unit test, trigger interrupt + denied integration
tests, three agent.cancel authorization tests (manage allowed, edit denied,
DISABLED policy denies even manage). 26 files / 175 tests pass.
Replace text-only PatchableTextStream with a unified StreamingAgentCard that
renders the full agent run lifecycle in a single Feishu interactive card:
- Tool-use panel: collapsible, shows each tool call with status (running/
success/error), input summary, and result/error in code blocks
- Reasoning panel: collapsible, streams thinking text inline then collapses
on completion
- Answer text: rendered via native Feishu markdown component (no post-row
round-trip)
Runner now captures previously-discarded SDK events:
- thinking_delta → reasoning stream
- tool_use id + input on content_block_start / assistant message
- tool_result from user messages (was entirely unhandled)
New files:
- card/trace-store.ts: per-run in-memory tool-use trace with secret redaction
- card/builder.ts: Feishu card JSON builder (tool panel + reasoning + text)
- card/streaming-card.ts: StreamingAgentCard controller (400ms throttled)
client.ts: add sendCard/patchCard raw JSON primitives
Two bugs were introduced when sendTextMessage was changed to auto-detect
message format (text/post/interactive):
1. Message type mismatch: sendTextMessage could create a text or post
message, but patchTextMessage only works on interactive cards.
Fix: add sendInteractiveCardMessage for streaming create (always
interactive, always patchable).
2. flushTextToSink state corruption: the text management after flush
had a flawed appendedDuringFlush heuristic that could lose text or
duplicate it. Fix: properly track sent vs unsent text by removing
the sent prefix length, keeping only the last chunk for future patches.
Also fix finish() to flush pending text regardless of currentMessageId.
- parsePostMessage: full Feishu post payload parser with locale fallback,
supports text/a/at/img/media/file/code_block/br/hr/emotion elements
- Trigger accepts post messages, extracts text + downloads attachments
- Post messages with attachments bypass batching, text-only posts batch
- Add unit tests (10) for all element types and edge cases
- sendApprovalCard: interactive card with configurable buttons
- resolveCard: patch card to show resolution state (green/red)
- ApprovalManager: register/resolve lifecycle with 5min timeout
- request_approval MCP tool: agent can ask user for confirmation
- Wire onCardAction in trigger handler and server startup
- Add unit tests (5) for card JSON, manager, and routing
- Create MessageBatcher: debounce 600ms, adaptive delay for long chunks,
max 8 messages/4000 chars before immediate flush, per (chatId, sender) key
- Integrate into trigger: text messages enqueued, slash commands and
file/image bypass batching, locked projects respond immediately
- Add unit tests (8) for batcher lifecycle and edge cases
- Add buildOutboundPayload: detect markdown format, isolate code blocks,
force plain text for tables, fallback from post to text on API rejection
- Add addReaction/removeReaction for processing status lifecycle
- Replace THUMBSUP with Typing→(remove on success | CrossMark on failure)
- Add unit tests for markdown rendering (15) and reactions (6)
