constant-time-analysis SKILL.md skillA

constant-time-analysis from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add outlinedriven/outline-driven-development/constant-time-analysis@git:20260912.5c5b759

Pins git:20260912.5c5b759 in mdr.lock. Pin the fingerprint instead.

Use when reviewing cryptographic code for timing side-channels, statically in compiled output or at runtime with statistical timing tests. Not for known-answer vectors: use wycheproof.

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

# Constant-time analysis

## Contract

| Field | Bound contract |
|---|---|
| Trigger | User needs static inspection of compiled assembly or VM bytecode for secret-dependent variable-time operations, or runtime and statistical evidence that a cryptographic implementation leaks timing information. |
| Authority | Reversible local: static mode is read-only and produces only local intermediate compiler output, discarded after analysis; runtime mode writes only a timing-test harness, its compiled binary, and measured sample files under a scratch directory, and rollback is deleting the scratch directory and compiled artifacts. The implementation under test is read and compiled but never edited. No remote mutation. |
| Side effect | A compiler or bytecode analyzer report read from local toolchain output (static), or a local timing-test harness and measured runtime samples (runtime). |

How to install

The exact contents, by fingerprint

mdr add outlinedriven/outline-driven-development/constant-time-analysis@sha256:313cc23ddbdc5b97

The line at the top of this page pins the label git:20260912.5c5b759, 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.
