Use when a developer wants to cut Claude or Anthropic API spend: "lower my Anthropic bill", "audit my Claude spend", "find prompt cache failures", "why is cache_read zero", "can we move this from Claude to OpenAI or a local model". Audits call sites, tokenizer risk, cache structure, batchability, and route candidates before any code edits.

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

# Lower Anthropic Bill

Use this worker for the installer happy path and for any developer who arrives
with a Claude bill, Anthropic usage export, or codebase that calls the Messages
API. The first deliverable is a local audit: call-site inventory, current price
assumptions, tokenizer re-baseline risk, cache-hit opportunities, batchability,
and route candidates. Do not edit code during the audit.

## Safety Gates

- Local-first. Static repo inspection and local usage-export parsing are the
  default. Do not upload source, prompts, traces, completions, datasets, repo
  paths, secrets, or private notes without explicit approval for that exact
  action.
- No provider spend without a named surface, model, data class, row count, and
  dollar envelope. Token-counting, cache probes, OpenAI migration tests, and
  GEPA reflection all need approval if they call a provider. Recommend the
  decision-sized test and explain its expected savings, time, and confidence;
  one approval may cover the named bounded test matrix.
- No silent source edits. Adding `cache_control`, changing model strings,
  rewriting prompts, or adding an OpenAI route is a follow-up change after the
…

How to install

The exact contents, by fingerprint
mdr add understudylabs/orchestra-agent-tools/lower-anthropic-bill@sha256:afd50db24654f34d

The line at the top of this page pins the label git:20260719.1185398, 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.
