rust-cli-clap from bjornmelin/dev-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add bjornmelin/dev-skills/rust-cli-clap@git:20260728.3aaa44bPins git:20260728.3aaa44b in mdr.lock. Pin the fingerprint instead.

Rust command-line apps with clap: derive and builder APIs, subcommands, flags, config and env precedence, stdout, stderr and JSON contracts, exit codes, completions, and binary distribution.
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
# Rust CLI Clap Build Rust command-line tools that are predictable, scriptable, pleasant in terminals, and easy to ship. ## Operating Model 1. Discover the existing CLI contract first: `Cargo.toml`, `src/bin`, `clap` definitions, integration tests, snapshots, release scripts, and README examples. 2. Preserve user-facing command behavior unless the task explicitly asks for a breaking change. If behavior changes, update tests and docs in the same patch. 3. Prefer `clap` derive for ordinary CLIs. Use the builder API when commands are generated dynamically, hidden/unstable command surfaces need custom construction, or macros make the shape harder to read. 4. Design command output as an API: human output on stdout, diagnostics on stderr, deterministic `--json`/machine output where automation is expected, and stable exit codes. 5. Keep command handlers thin. Parse into typed arguments, normalize config once, then call library code that tests can exercise without spawning a process. ## Reference Map Open only the section needed for the task: - `references/clap-parser-playbook.md` for `clap` derive/builder design, argument groups, validators, completions, and migration notes. …

How to install
mdr add bjornmelin/dev-skills/rust-cli-clap@sha256:31978246497927dfThe line at the top of this page pins the label git:20260728.3aaa44b, 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.
