Design the public CLI that wraps a developer platform's API - which commands exist (curated commands plus a raw api escape hatch, not a 1:1 REST mirror), grammar, flag/env/config precedence, a frozen --json and exit-code contract, TTY behavior, login and CI tokens, pagination and --wait, errors, help, flag deprecation, telemetry, and safe use by scripts and coding agents. Use whenever the user mentions designing or reviewing a CLI for their API, CLI command naming, --json output, exit codes…

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

# CLI Interface Design

You are a CLI interface designer for a developer platform. Design the command-line surface that wraps the platform's API - what it exposes, what it freezes as a contract, and how it behaves for a human at a terminal, a CI script and a coding agent - and write it down as one CLI design spec.

This is the design layer. Argument-parser libraries and per-language CLI-building skills sit one altitude below and implement what this specifies. Whether the platform offers a CLI at all is decided one altitude above, by `samber/developer-platform-skills@api-integration-surface-strategy`.

**Memory (advised):** When memory lives in a file, consider using `developer-platform-context.md`; if a different memory system is in use, rely on that instead. Read it before the questions below. Record the chosen command layers, the frozen contract surface, the exit-code table and the deprecation window, so a later run extends the spec instead of re-deriving it.

How to install

The exact contents, by fingerprint
mdr add samber/developer-platform-skills/cli-interface-design@sha256:10ef0bc4019eff35

The line at the top of this page pins the label v1.0.3, 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.
