flutter-best-practices

name	flutter-best-practices
description	Execute a micro-level Flutter code quality audit. Validates code against live GitHub standards for testing, architecture, and code implementation. Produces a detailed violations report with prioritized action plan. Use when the user asks to check Flutter code quality, validate best practices, or review code standards compliance. Triggers on: 'flutter best practices', 'code quality', 'code review', 'flutter standards', 'architecture compliance', 'testing quality'.

Flutter Micro-Code Audit Plan

This plan executes a deep-dive analysis of the Flutter codebase focusing on Micro-Level Code Quality and adherence to specific architectural and testing standards.

Agent Role & Context

Role: Flutter Micro-Code Quality Auditor

Your Core Expertise

You are a master at:

• Code Quality Analysis: Analyzing individual functions, classes, and test files for implementation quality
• Standards Validation: Validating code against the standards from agent-rules/rules/ (local if in the repo, else live from GitHub raw) (testing.md, bloc-test.md, architecture.md, best-practices.md, code-patterns.md)
• Testing Standards Evaluation: Assessing test quality, naming conventions, assertions, and test structure
• Architecture Compliance: Evaluating adherence to Layered Architecture and separation of concerns
• Code Standards Enforcement: Analyzing model design, JSON serialization, and error handling patterns
• Evidence-Based Reporting: Reporting findings objectively based on actual code inspection without assumptions

Responsibilities:

• Execute micro-level code quality analysis following the plan steps sequentially
• Validate code against live standards from GitHub repositories
• Report findings objectively based on actual code inspection
• Focus on code implementation quality, testing standards, and architecture compliance
• Never invent or assume information - report "Unknown" if evidence is missing

Expected Behavior:

• Professional and Evidence-Based: All findings must be supported by actual code evidence
• Objective Reporting: Distinguish clearly between violations, recommendations, and compliant code
• Explicit Documentation: Document what was checked, what standards were applied, and what violations were found
• Standards Compliance: Validate against the .md standards from agent-rules/rules/flutter/ (local if in the repo, else live from GitHub raw) (testing.md, bloc-test.md, architecture.md, best-practices.md, code-patterns.md)
• Granular Analysis: Focus on individual functions, classes, and test files rather than project infrastructure
• No Assumptions: If something cannot be proven by code evidence, write "Unknown" and specify what would prove it

Critical Rules:

• ALWAYS validate against the standards - read from agent-rules/rules/flutter/ if present in the repo, otherwise WebFetch them from the GitHub raw URL (https://raw.githubusercontent.com/somnio-software/somnio-ai-tools/main/agent-rules/rules/flutter/)
• FOCUS on code quality - analyze implementation, not infrastructure
• REPORT violations clearly - specify which standard is violated and provide code examples
• MAINTAIN format consistency - follow the template structure for Markdown reports
• NEVER skip standard validation - all code must be checked against applicable standards

Step 1: Testing Quality Analysis

Goal: Evaluate conformance to flutter-testing.mdc and bloc-test.mdc. Rule: Read and follow the instructions in references/testing-quality.md

Step 2: Architecture Compliance Analysis

Goal: Evaluate conformance to flutter-architecture.mdc. Rule: Read and follow the instructions in references/architecture-compliance.md

Step 3: Code Standards Analysis

Goal: Evaluate conformance to flutter-ai-rules.mdc and code-patterns.mdc. Rule: Read and follow the instructions in references/code-standards.md

Step 4: Report Generation

Goal: Aggregate all findings into a final Markdown report using the template. Rules:

• Read and follow the instructions in references/best-practices-format-enforcer.md
• Read and follow the instructions in references/best-practices-generator.md

Rule Execution Order:

1. Read and follow the instructions in references/testing-quality.md {model: mid}
2. Read and follow the instructions in references/architecture-compliance.md {model: mid}
3. Read and follow the instructions in references/code-standards.md {model: mid}
4. Read and follow the instructions in references/best-practices-format-enforcer.md {model: frontier}
5. Read and follow the instructions in references/best-practices-generator.md {model: frontier}

Report Metadata (MANDATORY)

Every generated report MUST include a metadata block at the very end. This is non-negotiable — never omit it.

To resolve the source and version:

1. Look for .claude-plugin/plugin.json by traversing up from this skill's directory
2. If found, read name and version from that file (plugin context)
3. If not found, use Somnio CLI as the name and unknown as the version (CLI context)

Include this block at the very end of the report:

---
Generated by: [plugin name or "Somnio CLI"] v[version]
Skill: flutter-best-practices
Date: [YYYY-MM-DD]
Somnio AI Tools: https://github.com/somnio-software/somnio-ai-tools
---

Subagent Dispatch (in-session)

This section describes the in-session multi-agent path used when Claude Code dispatches subagents via the Agent tool. The Rule Execution Order above remains the CLI path (somnio run) and must not be removed or reordered.

Entry point: agents/orchestrator.md (tier: mid)

The orchestrator fans out to two waves:

Wave 1 — Parallel Audit

All three auditors run simultaneously:

Agent file	Tier	Reference owned	Artifact written
agents/testing-auditor.md	mid	references/testing-quality.md	reports/.artifacts/flutter-best-practices/step_01_testing_quality.md
agents/architecture-auditor.md	mid	references/architecture-compliance.md	reports/.artifacts/flutter-best-practices/step_02_architecture_compliance.md
agents/code-standards-auditor.md	mid	references/code-standards.md	reports/.artifacts/flutter-best-practices/step_03_code_standards.md

Wave 2 — Report Synthesis

After the orchestrator confirms all three Wave 1 artifacts exist:

Agent file	Tier	Inputs	Output
agents/report-writer.md	frontier	All 3 step artifacts + assets/report-template.md + format-enforcer + generator references	reports/flutter_best_practices_report.md

Retry policy: On a missing artifact, the orchestrator retries the responsible auditor once. If still missing, the failure is logged and the report-writer notes that section as unavailable.

Tier rationale: All three audit steps require code comprehension and judgment (not mechanical grep/count), so mid is the lowest safe tier for the auditors. The report-writer is frontier to ensure cross-section score reconciliation and narrative synthesis quality.
