execution-algorithm-regression-testing-suite SKILL.md skillA
execution-algorithm-regression-testing-suite from himanshuj16/algo-trading-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add himanshuj16/algo-trading-skills/execution-algorithm-regression-testing-suite@v2.0.0Pins v2.0.0 in mdr.lock. Pin the fingerprint instead.

Use before promoting a change to an execution algorithm, replaying the candidate build against a recorded baseline across required stress scenarios and failing the build if implementation shortfall got measurably worse.
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
Use this skill when a change to an execution algorithm (TWAP, VWAP, POV, Implementation Shortfall) is about to be promoted to production and you need a machine-checkable answer to one question: **did this build get measurably worse than the baseline on the scenarios we replayed?** The engine replays baseline and candidate over a required set of market scenarios, compares $\Delta \text{IS}$, the fill-rate ratio and peak participation against configured thresholds, and returns `PASS_REGRESSION_APPROVED` / `FAIL_REGRESSION_REJECTED` plus an auditable `RegressionTestSuiteAuditReport` you can attach to a release record.
MiFID II **RTS 6 Article 5(1)** requires clearly delineated development and testing methodologies *prior to the deployment or substantial update* of a trading algorithm, and **Article 5(5)** requires further testing after substantial changes. A performance-regression gate is one component of that methodology, and the report it emits is the kind of artefact a venue asks for when it requires members to certify pre-deployment testing and **explain the means used** (RTS 7 Art. 10).

How to install
mdr add himanshuj16/algo-trading-skills/execution-algorithm-regression-testing-suite@sha256:9bdf4b495291102eThe line at the top of this page pins the label v2.0.0, 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.
