usage SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
usage from xsyetopz/claudetto is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add xsyetopz/claudetto/usage@git:20261016.3621f4bPins git:20261016.3621f4b in mdr.lock. Pin the fingerprint instead.

Reports where Claude Code usage went over a period, with the model calls of each run, the context that each call reads again, and the skills that the period did not use. Use when asked why usage or limits drained, or which skills to remove.
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>
Show the user where usage went, from the transcripts on this machine.
A run that makes many model calls reads its context again at each call, and that is a cost the user can measure.
{{include usage-figures}}
</task>
<procedure>
The bin `claudetto-usage` reads the transcripts under `~/.claude/projects/` and changes no file.
1. Run the report for the period the user names (default 7 days):
```bash
claudetto-usage --days 7
```
Run `claudetto-usage --help` for the options.
2. Read the output.
Each part has a label.
`Skills that the period did not use` names the source of its list.
</procedure>
<report>
Copy each figure from the output.
Do not compute, round, or convert a figure, because a figure that you change can be wrong.
Name the runs with the most calls and the largest sums first, because they hold most of the usage.
For unused skills, name the source that gave the list.
Let the user decide what to remove, and change no skill.
</report>Read the whole file at its exact version.
How to install
mdr add xsyetopz/claudetto/usage@sha256:e56d8b9b4ae02b4fThe line at the top of this page pins the label git:20261016.3621f4b, 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.
