Agent Island
Open-source status companion for your AI coding agents
Get notified when Codex finishes a turn
Require a fresh terminal event, deduplicate the turn, and retain the local Codex session return path.
agent-island.devLocal session data and no product telemetry
Separate local coding-session parsing from provider requests, update checks, and consent-based website analytics.
agent-island.devHow AI coding token cost is calculated
Price input, output, cache writes, and cache reads with a dated model table while keeping estimates separate from bills.
agent-island.devMonitor Codex state without alerting on every child task
Turn local rollout events into working, your-turn, stalled, and idle states with freshness and identity checks.
agent-island.devFix Agent Island install and update problems
Separate macOS first launch, Windows ZIP extraction, package-manager versions, and update checks.
agent-island.devFind a missing Claude Code or Codex session
Check local session roots, identity records, recency, filters, and file access without sharing transcripts.
agent-island.devBuild one Claude Code and Codex state contract across macOS and Windows
Normalize provider events into shared turn semantics, stable keys, and cross-platform fixtures.
agent-island.devWhy filesystem events still need a polling fallback
Use FSEvents and FileSystemWatcher for low latency while a bounded sweep repairs missed notifications.
agent-island.devMonitor large Claude Code transcript archives efficiently
Use append-aware cursors, bounded reads, and ordered evidence instead of repeatedly rescanning every transcript.
