Use before upgrading a broker SDK or OpenAPI spec, to diff two schema snapshots for removed endpoints, newly required parameters, enum mutations and type changes so CI fails before the change reaches an order path.
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
## When to Use Invoke this before upgrading a broker SDK version or pulling a new API specification (Binance, Coinbase, IBKR Client Portal and similar publish OpenAPI documents). Broker releases introduce silent breaking changes — a removed nested response field, a parameter that quietly became mandatory, a new order status the state machine has never seen. This skill diffs two schema snapshots and classifies what changed, so a CI job can fail the build before the change reaches an order path. The tool is a **gate**, and its failure modes are asymmetric: a false positive costs a developer a few minutes, a false negative ships a broken integration. Everything about its classification is biased accordingly. ## When NOT to Use - **As proof a release is safe.** It compares structure only. Rate limits, auth scope changes, altered matching-engine behaviour, changed rounding, new error codes returned in a 200 body — none are expressible in a schema, and none will appear in the report. A clean diff means "nothing structural broke", not "safe to deploy". - **On specifications it cannot fully resolve.** Only local (`#/...`) references are …

How to install
mdr add himanshuj16/algo-trading-skills/broker-api-changelog-diffing-tool@sha256:1c20f79774982ef6The line at the top of this page pins the label v3.0.0, 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.
