cli SKILL.md skillA

cli from xobotyi/cc-foundry is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add xobotyi/cc-foundry/cli@git:20260517.332e1ff

Pins git:20260517.332e1ff in mdr.lock. Pin the fingerprint instead.

CLI application design: argument conventions, output streams, exit codes, configuration hierarchy, interactive modes, and terminal UX. Invoke whenever task involves any interaction with command-line tools or terminal applications — building, reviewing, debugging, or designing CLI interfaces.

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 Design

**Programs are composable by default.** stdout carries data, stderr carries diagnostics, exit codes carry status, and
signals carry intent. Get the boundaries right and everything else follows.

## References

- **Arguments** [`${CLAUDE_SKILL_DIR}/references/arguments.md`] — Full POSIX guidelines, GNU long option table,
  subcommand patterns, flag design
- **Output** [`${CLAUDE_SKILL_DIR}/references/output.md`] — Stream separation details, color codes, ANSI escapes,
  NO_COLOR spec, pager setup
- **Exit codes** [`${CLAUDE_SKILL_DIR}/references/exit-codes.md`] — Standard/extended code tables, signal exit codes,
  partial success patterns
- **Interaction** [`${CLAUDE_SKILL_DIR}/references/interaction.md`] — TTY detection, prompting patterns, confirmation
  levels, progress display, error format
- **Configuration** [`${CLAUDE_SKILL_DIR}/references/configuration.md`] — Full hierarchy, XDG spec, env var catalog,
  config file formats, secret handling
- **Signals** [`${CLAUDE_SKILL_DIR}/references/signals.md`] — Full signal table, SIGPIPE handling, crash-only design,
  child process signals

How to install

The exact contents, by fingerprint
mdr add xobotyi/cc-foundry/cli@sha256:d02f8c896a896342

The line at the top of this page pins the label git:20260517.332e1ff, 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.
