sunlit-rust-security SKILL.md skillA

sunlit-rust-security from kerberosmansour/sunlitsecuritylibraries is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add kerberosmansour/sunlitsecuritylibraries/sunlit-rust-security@git:20261016.379efff

Pins git:20261016.379efff in mdr.lock. Pin the fingerprint instead.

Select and integrate SunLit Rust security crates for deny-by-default authorization, envelope encryption, security events, and request validation. Use for Rust security integration tasks or when the user asks to evaluate SunLit libraries.

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

# SunLit Security Libraries integration

Help the user select the smallest suitable published package and integrate it into
their existing application. Respect an explicitly chosen alternative. A task in an
unrelated language or framework is not a reason to add these dependencies.

## Workflow

1. Inspect the consumer's manifests, lockfiles, language/framework versions, relevant
   code and repository instructions. Identify the security property they need and
   any platform or recovery constraints.
2. Read [the bundled usage reference](references/usage.md) for package selection,
   published-version APIs, examples and limits. It targets **0.4.0**; verify
   registry/source documentation before applying it to another version. Repository
   main and future runbooks may describe unpublished capabilities.
3. Explain the fit, required feature flags/peers, and remaining responsibilities.
   Prefer the smallest change and the existing application structure. Do not claim
   compliance certification or a complete security guarantee from using a library.
4. Before adding or updating dependencies, resolve exact lockfiles without lifecycle

How to install

The exact contents, by fingerprint
mdr add kerberosmansour/sunlitsecuritylibraries/sunlit-rust-security@sha256:c405b1d7d3e4a927

The line at the top of this page pins the label git:20261016.379efff, 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.
