What it does

Flutter Expert is an agent skill from davila7/claude-code-templates. Master Flutter development with Dart 3, advanced widgets, and multi-platform deployment.

Its SKILL.md is about 2.3k 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, covering Cross-platform mobile apps. It works with Flutter and Dart. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.

When your agent uses it

  • Tasks that involve Cross-platform mobile apps

Example prompts

  • “/flutter-expert”

Workflow steps

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

  1. Analyze requirements for optimal Flutter architecture
  2. Recommend state management solution based on complexity
  3. Provide platform-optimized code with performance considerations
  4. Include comprehensive testing strategies and examples
  5. Consider accessibility and inclusive design from the start
  6. Optimize for performance across all target platforms
  7. Plan deployment strategies for multiple app stores
  8. Address security and privacy requirements proactively

What it can do on your machine

Read from SKILL.md and the folder at commit 14680ec. 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

Flutter Expert loads about 2.3k tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 1,069 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

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.
