Answers "why was that session slow?" from the agent transcript's own timestamps. Attributes wall-clock time to categories (tests/build, subagent dispatch, adversarial review, model thinking, stalls, user-away), ranks the biggest gaps, and names the specific commands behind them. Reads Claude Code session JSONL and Codex rollout JSONL. Modes: [transcript], --last, --skill <name>, --since <iso>, --compare <a> <b>.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# zuvo:profile-session — Where a session's wall-clock actually went Sessions get slow for boring, measurable reasons: a full suite re-run per task, four-minute adversarial passes that fired ten times, a sub-agent nobody was waiting on, an API stall. Guessing at which one is expensive — the 2026-07 pipeline forensics measured 28 sessions and found the dominant cost (thread-polling dead-air, ~88h) was **not** the one everyone blamed (adversarial review, 38 minutes total across all 28). This skill measures instead of guessing. It reads the transcript's timestamps, charges each gap to the activity that preceded it, and reports the ranked truth. **Scope:** wall-clock attribution for a single session, or a comparison of two, plus the token totals the profiler computes (`tokens` block). **Out of scope:** per-file / per-include context budgeting (`zuvo:context-audit`), skill quality (`zuvo:skill-eval`), fleet-wide trends (`~/.zuvo/runs.log` + `zuvo:retro`). ### Tokens come from the script or they do not get reported This line used to read *"Out of scope: token cost"*, and the profiler computed none — so every run …

How to install
mdr add greglas75/zuvo/profile-session@sha256:ddcc8903061c3c9fThe line at the top of this page pins the label git:20260906.015072f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
