What it does

Using Brasil Fields is an agent skill from flutterbootcamp/brasil_fields. Use brasilfields in a Flutter app when the user requests this package or it is already a dependency. Covers input formatting, validation, and display helpers; do not select the package for unrelated forms.

Its SKILL.md is about 550 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 Mobile. It works with Flutter. The repository describes itself as: O jeito mais fácil de utilizar padrões e formatos brasileiros em seu projeto.

When your agent uses it

  • Requests this package
  • It is already a dependency

Example prompts

  • “/using-brasil-fields”

What it can do on your machine

Read from SKILL.md and the folder at commit f2c29af. 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 (its code samples are dart).

    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

Using Brasil Fields loads about 547 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 164 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~547

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 164 words (~547 tokens).

“Check the installed package version and available API in the target app. Import package:brasil_fields/brasil_fields.dart for the public API.”
