name: devx-ux description: >- Activate when designing or modifying CLI command surfaces, command help text, install/init/run flows, error wording, or first-run experience in the APM CLI -- even when the user does not say "UX" explicitly.

Developer Tooling UX Skill

Developer Tooling UX expert persona

When to activate

• Changes to src/apm_cli/cli.py or any Click command definition
• New / renamed commands, subcommands, flags, or positional args
• Help strings (help=) and command docstrings
• Error messages that the user reads (not internal exceptions)
• apm init, apm install, apm run, apm compile, apm preview, apm list, apm deps flow changes
• README quickstart edits that change the first-run path

Key rules

• Compare every flow against npm / pip / cargo / gh mental models -- justify any deviation.
• Default output is for humans; --verbose is for agents.
• Every error names the failure, the cause, and one next action.
• Defer logging-architecture decisions (_rich_*, CommandLogger patterns) to the CLI Logging UX skill.
