Analyzes Claude Code session traces (JSONL) and draft task files to report token usage per task. Use when asked about token usage, session costs, or task efficiency metrics.
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
# Task Token Usage Analyzes Claude Code conversation traces to report token consumption per task. ## When to Use - "list tasks with token usage" - "show me token usage for each task" - "how many tokens did task X use?" - "what tasks ran in the last N hours?" - "compare token usage across tasks" ## How It Works 1. Scans `~/.claude/projects/<project>/` for JSONL session traces 2. Extracts `input_tokens`, `output_tokens`, `cache_read_input_tokens` from each assistant message 3. Optionally matches sessions to draft task files in `coworker/tasks/issues/draft/` 4. Prints a summary table grouped by task ## Usage Run the bundled script: ```bash python3 coworker/skills/task-token-usage/scripts/list-tasks.py [OPTIONS] ``` ### Options | Flag | Description | |------|-------------| | `--recent N` | Only show sessions from last N hours (default: 24) | | `-d, --detail` | Per-session breakdown instead of grouped summary | | `-a, --all` | Show all sessions (no time filter) | ### Examples ```bash # Summary of last 12 hours python3 coworker/skills/task-token-usage/scripts/list-tasks.py --recent 12 # Detailed per-session view for all time …

How to install
mdr add platonai/browser4/task-token-usage@sha256:30be332fe6d8b8d8The line at the top of this page pins the label git:20260710.5764b6f, 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.
