Use when a developer wants to inspect Anthropic or Claude billing evidence from email, invoices, usage exports, or an authenticated billing website: "scan my Anthropic bills", "check billing emails", "look at the console usage page", "find spend hotspots from receipts". Optional, approval-gated evidence source for lower-Anthropic-bill audits.
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
# Inspect Billing Sources Use this worker only after the developer asks to use bill evidence, email, an invoice, a usage export, or an authenticated billing website. This complements repo inspection: it finds spend hotspots from what the provider charged, then hands the result back to `lower-anthropic-bill`. ## Safety Gates - Get explicit approval for the exact read scope before using email, browser, or account surfaces. Name the provider, account, date range, and search/query or page class before reading. - Prefer exports or screenshots the developer provides. Use Gmail, browser, Chrome, or another connector only when the coding harness exposes that tool and the user approves it in the current thread. - Read billing metadata only: provider, period, invoice amount, usage amount, model, token counts, cache usage fields, request count, and route labels if already visible. Do not read prompts, completions, traces, API keys, team member lists, customer names, repo names, domains, support tickets, or payment card details. - Do not send emails, click billing mutations, create API keys, change plans, …

How to install
mdr add understudylabs/orchestra-agent-tools/inspect-billing-sources@sha256:dea2aaaee47d01f2The line at the top of this page pins the label git:20260624.ce4446a, 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.
