What it does

Gleam Practice is an agent skill from mizchi/skills. Use when writing or reviewing Gleam code on the Erlang target — especially Wisp + Mist HTTP services, OTP-based processes (genserver / supervisor analogues), justfile workflows, gleeunit testing, gleam format, GitHub Actions CI, and performance measurement. Trigger on gleam.toml, .gleam files, or Erlang/BEAM-related symptoms even if the user does not say "Gleam" by name.

Its SKILL.md is about 5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including assets (for example `README.md`, `SKILL-ja.md` and `assets/README.md`).

It sits in DevOps & Cloud, covering CI/CD. It works with GitHub Actions. The repository describes itself as: Agent skills by mizchi, distributed via APM.

When your agent uses it

  • Reviewing Gleam code on the Erlang target — especially Wisp + Mist HTTP services
  • OTP-based processes (genserver / supervisor analogues)
  • Justfile workflows
  • Gleeunit testing

Example prompts

  • “/gleam-practice”

Requirements

  • Node.js

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. gleam test
  2. Check failing / new snapshots.
  3. gleam run -m birdie
  4. Review snapshots and commit.

What it can do on your machine

Read from SKILL.md and the folder at commit 62f5808. 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

    Ships script files (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • just

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

  • Network

    Links to these hosts (documentation or services it may open):

    • gleam.run
    • hexdocs.pm
    • just.systems

    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

Gleam Practice loads about 5k tokens when it runs. Until then it costs about 99 tokens; SKILL.md has 1,735 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~99
When it runs · the whole SKILL.md, loaded when a task matches
~5k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,735 words (~4,952 tokens).

“Use this when creating a new Gleam project, improving an existing one, or implementing with a wisp + mist + gleam_otp + just stack.”
