Slack Reporter Skill

Specification for sending reports to Slack in Block Kit format.

Posting Method

Important: To prevent Japanese character encoding issues, always send via file.

bash

# 1. Save payload to file
cat > /tmp/slack_payload.json << 'EOF'
{
  "blocks": [...]
}
EOF

# 2. Send via file (-d @file format)
curl -X POST -H "Content-Type: application/json" \
  -d @/tmp/slack_payload.json \
  "$SLACK_WEBHOOK_URL"

Prohibited: Passing JSON directly with -d '{...}' causes Japanese character corruption.

Block Kit Structure

Reports support two languages: Japanese (ja) and English (en). Use the appropriate template based on the --lang option.

Best Practices

•Include full context: Post summaries can be up to 200 chars; include engagement metrics
•Use emojis: Add emojis to section headers for better visibility
•Use hierarchy: Separate logical sections with dividers
•Detailed analysis: Trend analysis should explain why topics are trending, not just list them
•Engagement metrics: Always include ♡ (likes), 🔁 (reposts), 💬 (replies), 👁 (views)
•Clear actions: Present specific next steps with links or handles in "Action Items"

Error Response Format

Use the following format for error notifications:

        "text": "X Analysis Report - Error",
        "emoji": true
      }
    },
    {
      "type": "section",
      "text": {
        "type": "mrkdwn",
        "text": "*Error:*\nLogin required. Please log into X in Chrome and try again."
      }
    }
  ]
