Roslyn Analyzer Hooks

Overview

Comprehensive Roslyn analyzer integration for dotnet-agent-harness providing real-time code analysis through agent hooks and enforced quality gates via git hooks.

Architecture

Layer 1: Agent-Level Hooks (Real-time)

• Trigger: Post-edit on .cs files
• Execution: Async with 60s timeout
• Scope: Single file analysis
• Output: JSON with violations + skill recommendations

Layer 2: Git Hooks (Commit/Push)

• pre-commit: Staged files analysis + dotnet format
• pre-push: Full solution build + tests + doc validation
• Enforcement: Blocks on errors and warnings

Configuration

Environment Variables

# Skip all analyzer checks (default: false, analyzers run by default)
export DOTNET_AGENT_HARNESS_SKIP_ANALYZERS=true

# Configure timeout (default: 60 seconds)
export DOTNET_AGENT_HARNESS_ANALYZER_TIMEOUT=120

# Minimum severity to report (Error/Warning/Info)
export DOTNET_AGENT_HARNESS_ANALYZER_SEVERITY=Warning

# Execution mode (sync/async)
export DOTNET_AGENT_HARNESS_ANALYZER_MODE=async

Project-Level (.editorconfig)

[*.cs]
# Enable all analyzers
dotnet_analyzer_diagnostic.severity = warning

# Category-based configuration
dotnet_analyzer_diagnostic.category-security.severity = error
dotnet_analyzer_diagnostic.category-performance.severity = warning

# Specific rule overrides
dotnet_diagnostic.CA2007.severity = suggestion  # ConfigureAwait
dotnet_diagnostic.CA1816.severity = error       # GC.SuppressFinalize
