dependency-pinning-and-reproducible-builds SKILL.md skillA
dependency-pinning-and-reproducible-builds 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/dependency-pinning-and-reproducible-builds@v2.0.0Pins v2.0.0 in mdr.lock. Pin the fingerprint instead.

Use when auditing a requirements file before it is used with pip hash-checking mode, to verify exact == pins and valid strong hashes. It audits; resolving versions is pip-compile or uv with generate-hashes.
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 on the requirements files behind quantitative research environments, backtesting frameworks, and live trading deployments. Floating dependency specifiers (`pandas>=2.0`, or a bare `numpy`) let a third-party release change floating-point behaviour, deprecate an API, or shift a calculation between two installs of the "same" code — which invalidates historical backtests and produces production model drift that looks like alpha decay. This module parses requirements lines, reports which are pinned to an exact version and carry a valid strong hash, and drafts a lockfile skeleton for remediation. ## When NOT to Use - **As a resolver.** It cannot tell you *which* version to pin, and it cannot discover transitive dependencies. Use `pip-compile --generate-hashes` or `uv pip compile --generate-hashes` for that; use this to audit the result. - **As proof that `pip install --require-hashes` will succeed.** Hash-checking mode requires hashes for *all* dependencies and errors on any that is not spelled out. This tool sees only the lines you hand it, so it cannot confirm transitive completeness — a file can pass this audit and still fail the install. …

How to install
mdr add himanshuj16/algo-trading-skills/dependency-pinning-and-reproducible-builds@sha256:debabec817b836eeThe 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.
