@agimon-ai/doompi-log

Session metrics, findings, sink status, and a Log Metrics overlay for Pi.

Part of the DoomPi distribution.

The extension aggregates telemetry it observes in-process and can query historical data from @agimon-ai/log-sink-mcp.

Alpha: metric attribution and UI contracts may change between releases.

Requirements

• Node.js 22.19.0 or newer
• Pi 0.85.0 and Pi TUI 0.85.0

Install

doompi init and dpi init include Log in default.packages in .doom/modes.yaml. Remove it or move it to a named layer to change which major modes load it. Pi discovers its sole extension entry through package.json.pi.extensions. For standalone Pi:

pi install npm:@agimon-ai/doompi-log

Use SPC h l to open the current session's Log Metrics overlay.

What is collected

The in-process aggregator tracks operational records such as turn token totals, cache use, tool calls and failures, operation durations, recent errors, and event counts. It derives findings from those records without requiring an external sink.

Historical panels resolve a sink over HTTP first and then use the Log Sink CLI fallback. Without a reachable sink, current-session headline metrics, findings, errors, and tool metrics still work; historical top-consumer and burn-rate views are unavailable. Sink failures are reported in status rather than failing the Pi session.

Turn cost attribution is contextual: when a turn invokes several tools, the emitted turn total can be associated with each participating tool. The overlay uses that value for ranking, not as a precise per-tool share.

Keys: r refreshes, g changes dimension, p changes period, ? opens details, and Escape closes.

Telemetry controls

Variable	Effect
AGENT_TELEMETRY_DISABLED	Disables the extension's telemetry export
OTEL_SDK_DISABLED	Disables OpenTelemetry SDK export
AGENT_OTEL_TRACES	Enables/disables trace export; logs can remain enabled

File fallback is opt-in through host options. The absence of a configured or reachable endpoint does not prevent in-process aggregation. Exceptions and caller-supplied attributes can still be sensitive; do not assume "metadata" is harmless.

The overlay requires a TUI. The aggregator, findings, and metrics-source APIs can be embedded in headless hosts.

Public API

import {
  installDoomLogRuntime,
  deriveFindings,
  LogMetricsAggregator,
  openLogMetricsOverlay,
} from '@agimon-ai/doompi-log';

Normal Pi activation should use the discovered extensions/pi entry. Host integrations can call installDoomLogRuntime to install package resources into the shared runner-scoped Cordis host. The extension entry manages its plugin lifecycle and releases the host lease when the Pi session shuts down. Focused exports provide metrics types, the metrics source, and the overlay component.
