Feishu/Lark Notification

Send a notification: $ARGUMENTS

Overview

This skill provides Feishu/Lark integration for ARIS. 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.
