Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by flutter on GitHub. Read the source before you install it.

Installation

Install the Api Review AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/flutter/agent-plugins/tree/main/.agents/agents/reidbaker-agent/skills/api-review
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/flutter/agent-plugins.git /tmp/agent-plugins
mkdir -p .claude/skills
cp -r /tmp/agent-plugins/.agents/agents/reidbaker-agent/skills/api-review .claude/skills/api-review

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Api Review in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Api Review on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Api Review is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

API review skill

This skill reviews code against the canonical API Design guidelines.

Instructions

Load Guidelines: Read the API design guidelines from references/canonical_api_design.md to ensure they are fully available in the context.
Identify Target: Identify the code to review.
- If the user specified files (e.g., "review main.dart"), use those.
- If the user has an open file in their context, assume that is the target.
- If neither, ask the user to specify the target files.
Analyze: For each target file, perform a deep analysis against the "Foundations of Canonical API Design Principles" (loaded in step 1), specifically looking for:
- Contract-First: Is the interface clear and decoupled from implementation?
- KISS/YAGNI: Are there unnecessary parameters or over-generalized features?
- Ergonomics: Are names intent-revealing? Do they follow the Principle of Least Astonishment?
- CQS: Are commands and queries separated?
- Safety: Are types used strictly (Enums vs Strings)? Is validation visible?
- Explicit Configuration: Are dependencies explicitly injected rather than implicitly resolved via global state, registries, or environment variables?
Report: Generate a structured report:
- Score: Give a letter grade (A-F) based on alignment.
- Critical Issues: Violations that must be fixed (e.g., severe strictness or safety issues).
- Suggestions: Ergonomic improvements (renaming, rearranging).
- Code Examples: Provide before vs after code blocks for the suggested improvements.
- Save the report as a markdown artifact in the conversation artifacts directory (e.g., <appDataDir>/brain/<conversation-id>/api_review_results.md).

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Api Review AI skill do?

Reviews the specified code against the canonical API Design guidelines. Use this skill when the user asks for an API review or to check code against API design principles.

Why use Api Review on TypingMind?

Because you install it once and use it with any model. Api Review is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Api Review in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/flutter/agent-plugins/tree/main/.agents/agents/reidbaker-agent/skills/api-review. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Api Review?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Api Review?

As many as you like. As long as a model supports skills, you can use Api Review with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Api Review AI skill free?

Yes. It is published on GitHub by flutter under the BSD-3-Clause license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
