At a glance

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"…

  • Does not say UX explicitly
  • SKILL.md covers When to activate and Key rules
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Monitoring and alerting

What it does

Devx UX is an agent skill from microsoft/apm, published by the product's own GitHub organization. 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.

Its SKILL.md is about 280 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Monitoring and alerting. The repository describes itself as: Agent Package Manager. The licence is MIT.

When your agent uses it

  • Does not say UX explicitly
  • Tasks that involve Monitoring and alerting

Example prompts

  • “/devx-ux”

What it can do on your machine

Read from SKILL.md and the folder at commit 280b8a7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Devx UX loads about 284 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 114 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~284

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
