Data Sources

Agent Session Pulse reads from the platform-specific Kiro application data directory:

Within that directory:

<Kiro App Data>/
├── User/globalStorage/kiro.kiroagent/  # Sessions
├── logs/*/main.log                      # Health stats (crashes, errors, updates)
└── logs/*/window*/exthost/exthost.log   # Load performance metrics

Additional sources:

~/.kiro/agents/                          # Global custom agents
.kiro/agents/                            # Workspace custom agents
~/.kiro/skills/                          # Global skills
