What it does

Rebuilding Flutter Tool is an agent skill from flutter/flutter. Rebuilds the Flutter tool and CLI. Use when a user asks to compile, update, regenerate, or rebuild the Flutter tool or CLI.

Its SKILL.md is about 170 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts.

It sits in Mobile, covering Cross-platform mobile apps. It works with Flutter and Dart. The repository describes itself as: Flutter makes it easy and fast to build beautiful apps for mobile and beyond. The licence is BSD-3-Clause.

When your agent uses it

  • A user asks to compile
  • Rebuild the Flutter tool

Example prompts

  • “Use the rebuilding-flutter-tool skill to rebuild the Flutter tool and CLI. An agent skill from flutter/flutter”
  • “/rebuilding-flutter-tool”

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Execute
  2. Verification & Error Handling

What it can do on your machine

Read from SKILL.md and the folder at commit 8679894. 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 1 file in scripts/ (Dart), which the agent can run.

    Shell commands in SKILL.md call:

    • 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

Rebuilding Flutter Tool loads about 167 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 63 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~167

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); the scripts in this folder are not scanned.

Step 1: Execute

  • Action: Run the rebuild script: dart .agents/skills/rebuilding-flutter-tool/scripts/rebuild.dart
