Costclaw
ucsandman · App
Costclaw audits Claude Code from the session logs already on your disk. It estimates where token spend leaks, scores your setup across six pillars and ranks counterfactual opportunities by estimated token value, and it can score a CLAUDE.md file. Dollar figures are API-equivalent estimates from a dated rate table, not billing proof, and your prompts are analysed locally rather than uploaded. It suits people who want to review their own Claude Code usage and setup.

Why it's useful
You can see where your Claude Code token usage goes and what to look at in your setup, using only the logs on your own disk.
What you could do with it
- Audit all your Claude Code projects, or point it at one project folder, to see an estimate of cache-miss exposure.
- Score a CLAUDE.md file and see how your setup rates across the six pillars.
- Write a shareable SVG score card showing your score, score band and cache hit rate.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Licence and provenance
- finding
- no LICENCE file at the root (.)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Local Claude Code usage estimates, cache analysis, and rule-based setup checks. Your prompts stay on your machine.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.16.2, the file with digest sha512-fzkqa76Avp1Oz1EgxqhLA/WFPu1LOzhBYZGm2FIF9nlAWezZh18CfNuJXcVUUpdhYGn6xUFjv6uRAQnZRihKLQ==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y costclaw@0.16.2Pinned to 0.16.2, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
