Event Log

event-log

An append-only structured JSONL event log giving Kite continuity across sessions — without reading every log file.

What it does

Writes structured events to ~/.openclaw/events.jsonl. Each event captures a timestamp, type, session ID, human-readable summary, and optional metadata. Kite can query the log at the start of any session to instantly know what happened recently.

Event file

~/.openclaw/events.jsonl

Each line is one JSON event:

{
  "ts": "2026-02-21T17:00:00Z",
  "type": "note",
  "session": "agent:main:abc",
  "summary": "Gateway auth fixed",
  "meta": {}
}

Script location

${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs

Also symlinked in skill scripts for reference:

CLI usage

# Log an event
node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs log \
  --type note --summary "Started working on X"

# With metadata
node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs log \
  --type notification_sent \
  --summary "Sent stock alert" \
  --meta '{"channel":"telegram","topic":"stock"}'

# View last 20 events
node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs tail

# View last 50
node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs tail --n 50

# Events from today
node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs today

# Search summaries
node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs search "stock"

# Filter by type
node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs type notification_sent

# Events since a date
node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs since "2026-02-21"

# Stats: counts by type, today/week
node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs stats

Programmatic API

const { logEvent } = require("${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs");

logEvent("notification_sent", "Stock alert fired", { channel: "telegram" });
logEvent("cron_ran", "web-monitor check complete", { success: true, duration_ms: 312 });
logEvent("error", "Failed to reach Eric Bloodaxe URL", { url: "https://...", code: 503 });

Trigger phrases (Kite)

When the user says any of these, Kite should query the event log:

• "What happened today?"
• "What did you do today?"
• "Show recent events"
• "Show me the log"
• "Log a note: …"
• "What's been running?"
• "Any errors recently?"
• "Show notifications"

Session startup

At the start of each main session, Kite should run:

node ${EVENT_LOG_HOME:-$HOME/projects/event-log}/event-log.cjs today

This gives immediate context without reading every log file.
