Feishu/Lark Notification

Send a notification: $ARGUMENTS

Overview

This skill provides Feishu/Lark integration for MH Agent. It is designed as an internal utility — other skills call it at key events (experiment done, review scored, checkpoint waiting). It can also be invoked manually.

Zero-impact guarantee: If no feishu.json config exists, this skill does nothing and returns silently. All existing workflows are completely unaffected.

Configuration

The skill reads ~/.claude/feishu.json. If this file does not exist, all Feishu functionality is disabled — skills behave exactly as before.

Config Format

{
  "mode": "push",
  "webhook_url": "https://open.feishu.cn/open-apis/bot/v2/hook/YOUR_WEBHOOK_ID",
  "interactive": {
    "bridge_url": "http://localhost:5000",
    "timeout_seconds": 300
  }
}

Modes

Mode	"mode" value	What it does	Requires
Off	"off" or file absent	Nothing. Pure CLI as-is	Nothing
Push only	"push"	Send webhook notifications at key events. Mobile push, no reply	Feishu bot webhook URL
Interactive	"interactive"	Full bidirectional. Approve/reject from Feishu, reply to checkpoints	feishu-claude-code running

Workflow

Step 1: Read Config

cat ~/.claude/feishu.json 2>/dev/null

• File not found → return silently, do nothing
• "mode": "off" → return silently, do nothing
• "mode": "push" → proceed to Step 2 (push)
• "mode": "interactive" → proceed to Step 3 (interactive)

Step 2: Push Notification (webhook)

Send a rich card to the Feishu webhook:

curl -s -X POST "$WEBHOOK_URL" \
  -H "Content-Type: application/json" \
  -d '{
    "msg_type": "interactive",
    "card": {
      "header": {
        "title": {"tag": "plain_text", "content": "TITLE"},
        "template": "COLOR"
      },
      "elements": [
        {"tag": "markdown", "content": "BODY"}
      ]
    }
  }'

Card templates by event type:

Event	Title	Color	Body
experiment_done	Experiment Complete	green	Results table, delta vs baseline
review_scored	Review Round N: X/10	blue (≥6) / orange (<6)	Score, verdict, top 3 weaknesses
checkpoint	Checkpoint: Waiting for Input	yellow	Question, options, context
error	Error: [type]	red	Error message, what failed
pipeline_done	Pipeline Complete	purple	Final summary, deliverables
custom	Custom	blue	Free-form message from $ARGUMENTS

Return immediately after curl — push mode never waits for a response.

Step 3: Interactive Notification (bidirectional)

Interactive mode uses feishu-claude-code as a bridge:

1. Send message to the bridge:

   curl -s -X POST "$BRIDGE_URL/send" \
     -H "Content-Type: application/json" \
     -d '{"type": "EVENT_TYPE", "title": "TITLE", "body": "BODY", "options": ["approve", "reject", "custom"]}'
   

2. Wait for reply (with timeout):

   curl -s "$BRIDGE_URL/poll?timeout=$TIMEOUT_SECONDS"
   

   Returns: {"reply": "approve"} or {"reply": "reject"} or {"reply": "user typed message"} or {"timeout": true}

3. On timeout: Fall back to AUTO_PROCEED behavior (proceed with default option).

4. Return the user's reply to the calling skill so it can act on it.

Step 4: Verify Delivery

• Push mode: Check curl exit code. If non-zero, log warning but do NOT block the workflow.
• Interactive mode: If bridge is unreachable, fall back to push mode (if webhook configured) or skip silently.

Helper Function (for other skills)

Other skills should use this pattern to send notifications:

### Feishu Notification (if configured)

Check if `~/.claude/feishu.json` exists and mode is not "off":
- If **push** mode: send webhook notification with event summary
- If **interactive** mode: send notification and wait for user reply
- If **off** or file absent: skip entirely (no-op)

This check is always guarded. If the config file doesn't exist, the skill skips the notification block entirely — zero overhead, zero side effects.

Event Catalog

Skills send these events at these moments:

Skill	Event	When
/auto-review-loop	review_scored	After each round's review score
/auto-review-loop	pipeline_done	Loop complete (positive or max rounds)
/auto-paper-improvement-loop	review_scored	After each round's review score
/auto-paper-improvement-loop	pipeline_done	All rounds complete
/run-experiment	experiment_done	Screen session finishes
/idea-discovery	checkpoint	Between phases (if interactive)
/idea-discovery	pipeline_done	Final report ready
/monitor-experiment	experiment_done	Results collected
/research-pipeline	checkpoint	Between workflow stages
/research-pipeline	pipeline_done	Full pipeline complete

Key Rules

• NEVER block a workflow because Feishu is unreachable. Always fail open.
• NEVER require Feishu config — all skills must work without it.
• Config file absent = mode off. No error, no warning, no log.
• Push mode is fire-and-forget. Send curl, check exit code, move on.
• Interactive timeout = auto-proceed. Don't hang forever waiting for a reply.
• Respect AUTO_PROCEED: In interactive mode, if the user doesn't reply within timeout, use the same auto-proceed logic as the calling skill.
• No secrets in notifications. Never include API keys, tokens, or passwords in Feishu messages.
