Sentry open-sources tattletale: trace Claude Code and Codex agent sessions for token inefficiency
zeeg · x · 2026-11-12
Zed's CEO highlights that raw agent telemetry beats just asking Claude to analyze local transcripts — you can actually interrogate the data to find why sessions are token inefficient.
getsentry/tattletale (MIT) sends your Claude Code, Codex and other coding-agent sessions into Sentry agent tracing. Setup: paste the repo URL to your agent and have it configure forwarding to a new Sentry project. Benefits: aggregated traces across devs to spot codebase-level patterns, and cross-machine session tracking.
