flutter-core-modules: Skill for Claude Code

.claude/skills/feature-review/SKILL.md

feature-review is a skill for Claude Code from sampaio-tech/flutter-core-modules. It costs 69 tokens per session (1,912 once invoked), scanned A, original, MIT.

A Flutter review feature that can ask users for an in-app store rating or open an email app for feedback.

In plain words
What is it for?
Use it for rate-this-app flows, links to an app-store listing, and feedback buttons that open an email client.
Why use it?
It keeps rating and feedback actions behind reusable application code instead of making each screen handle the platform details itself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

feature-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Feature: Review

Purpose: Provides two independent capabilities — (1) request the native in-app review dialog via in_app_review, and (2) launch an email feedback client via url_launcher. Both are wrapped behind clean architecture layers.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
