ubuntu-slim	261	65.6%	Lightweight execution
ubuntu-latest	137	34.4%	Standard GitHub runner

Runner Strategy: Strong preference (66%) for ubuntu-slim suggests cost optimization and faster startup times are prioritized.

Concurrency Management

Concurrency Group Patterns

Pattern	Count	% of Workflows	Purpose
gh-aw-${workflow}	49	69.0%	Per-workflow serialization
gh-aw-${workflow}-${issue/pr}	19	26.8%	Per-artifact serialization
gh-aw-copilot-${context}	2	2.8%	Copilot-specific grouping

Concurrency Insights:

• 100% use concurrency groups - no workflows allow parallel runs
• Per-workflow serialization dominates (69%) - prevents multiple instances of same workflow
• Artifact-level serialization (27%) - allows multiple workflows but one per issue/PR
• Prevents resource contention and ensures agent actions don't conflict

Interesting Findings

1. Universal Single-Job Architecture

Every workflow uses exactly 1 job. This is remarkable standardization and suggests the gh-aw compiler enforces this pattern. Benefits:

• Simplified execution model
• No cross-job data passing complexity
• Easier debugging and monitoring

2. PR-Centric Output Strategy

87% of workflows can create pull requests, making code modification the dominant output type. This positions agentic workflows as "code suggestion engines" rather than just reporting tools.

3. Schedule + Manual Trigger Dominance

44% of workflows use the exact pattern schedule + workflow_dispatch. This "automated with override" pattern provides:

• Regular autonomous execution
• On-demand manual triggering for testing/urgent runs
• Best of both automation worlds

4. Minimal MCP Server Usage

Despite 20 available MCP servers, most workflows (78%) use 0-1 servers. This suggests:

• Native GitHub capabilities are sufficient for most tasks
• MCP servers are specialized tools for specific workflows
• Lightweight integration preferred over heavy dependencies

5. Size Consistency Despite Complexity

Files range from 76 KB to 385 KB, but 80% fall within 150-280 KB range (130 KB spread), indicating standardized structure despite varied functionality.

6. Zero Write Access to Actions

No workflow has actions:write permission, preventing workflows from modifying themselves or other workflows. This is a critical security boundary.

7. Discussions as Reporting Channel

38% of workflows use discussions with 83% write permission rate, establishing discussions as the primary "reporting" channel separate from actionable issues/PRs.

8. Business-Hours Scheduling Bias

Scheduled workflows cluster around business hours (9 AM - 6 PM UTC), with multiple weekday-only schedules, suggesting workflows are designed to support human teams rather than 24/7 autonomous operation.
