Safe Output Configurations

Most Common Patterns:

1. Discussion + Missing Tool (18 workflows):

   {"create_discussion":{"max":1},"missing_tool":{}}

   Used for: Scheduled reports and analysis workflows

2. Issue Creation + Missing Tool (12 workflows):

   {"create_issue":{"max":1,"min":1},"missing_tool":{}}

   Used for: Workflows that must create tracking issues

3. Comment + Missing Tool (9 workflows):

   {"add_comment":{"max":1},"missing_tool":{}}

   Used for: Interactive comment-responding agents

Custom Safe Outputs

Some workflows define custom safe output actions:

• notion-add-comment: Add comments to Notion pages (3 workflows)
• post-to-slack-channel: Post messages to Slack channels (3 workflows)
• report-diagnostics-to-pull-request: Post diagnostic findings to PRs (3 workflows)
• add_labels: Add labels with controlled vocabulary (1 workflow - poem-bot)

Structural Characteristics

Job Complexity

• Average Jobs per Workflow: 6.47 jobs
• Minimum Jobs: 3 jobs
• Maximum Jobs: 14 jobs (poem-bot.lock.yml)
• Modal Value: 6 jobs (most common)

Job Distribution:

• 3 jobs: 2 workflows (5.3%)
• 4 jobs: 1 workflow (2.6%)
• 6 jobs: 24 workflows (63.2%)
• 7 jobs: 6 workflows (15.8%)
• 8 jobs: 3 workflows (7.9%)
• 9 jobs: 2 workflows (5.3%)
• 14 jobs: 1 workflow (2.6%)

Steps per Job

• Average Steps per Job: 9.13 steps
• Minimum Steps: 1 step
• Maximum Steps: 50 steps (mcp-inspector.lock.yml)
• Modal Range: 3-12 steps (most common)

Step Distribution Patterns:

• Short jobs (1-5 steps): Coordination and output collection jobs
• Medium jobs (10-15 steps): Setup and configuration jobs
• Long jobs (30-50 steps): Main agent execution jobs with extensive tooling

Workflows with Highest Step Counts:

1. mcp-inspector.lock.yml: 50 steps
2. github-mcp-tools-report.lock.yml: 48 steps
3. unbloat-docs.lock.yml: 44 steps
4. q.lock.yml: 44 steps

Average Lock File Structure

Based on statistical analysis, a typical .lock.yml file has:

• Size: ~200 KB
• Jobs: 6-7 jobs
• Steps per Job: 9-12 steps
• Permissions: Read-all for agent job, write for output jobs
• Triggers: workflow_dispatch + (schedule OR event-based)
• Timeout: 8-10 minutes
• Engine: Copilot (60%) or Claude (53%)

Permission Patterns

Most Common Permissions

Based on permission grants across all workflows:

Permission	Total Grants	Read	Write
contents	127	82	45
pull-requests	47	18	29
discussions	38	8	30
issues	55	24	31
actions	26	13	13
security-events	1	1	0
models	1	1	0

Total Permission Grants: 295

• Read permissions: 150 (50.8%)
• Write permissions: 145 (49.2%)

Permission Strategy Patterns:

1. Agent Job: Typically read-all permissions for repository access
2. Output Jobs: Specific write permissions (issues, discussions, pull-requests)
3. Minimal Jobs: Coordination jobs with no permissions

Permission Distribution by Job Type

• Pre-activation jobs: No permissions (authorization checks only)
• Activation jobs: Write permissions for reactions and initial responses
• Agent jobs: Read-all for comprehensive codebase access
• Output jobs: Targeted write permissions for creating issues, discussions, or comments
• Detection jobs: No permissions (analysis only)

Engine & Concurrency Patterns

Engine Distribution

Identified from concurrency group patterns:

Engine	Workflow Count	Percentage
Copilot	23	60.5%
Claude	20	52.6%
Codex	4	10.5%
Custom	4	10.5%

Note: Some workflows are engine-agnostic (using gh-aw-${{ github.workflow }}), accounting for overlap.

Concurrency Patterns

Concurrency Group Pattern	Count	Purpose
gh-aw-copilot-${{ github.workflow }}	23	Copilot engine concurrency control
gh-aw-claude-${{ github.workflow }}	20	Claude engine concurrency control
gh-aw-${{ github.workflow }}	10	Generic workflow concurrency
gh-aw-codex-${{ github.workflow }}	4	Codex engine concurrency control
gh-aw-custom-${{ github.workflow }}	4	Custom engine concurrency control

Pattern: Each workflow uses concurrency groups to prevent simultaneous runs, with engine-specific groups for agent jobs.

Timeout Configuration

• Average Timeout: 8.55 minutes
• Minimum Timeout: 5 minutes
• Maximum Timeout: 10 minutes
• Most Common: 10 minutes (agent jobs), 5 minutes (supporting jobs)

Timeout Strategy:

• Agent jobs: 10 minutes (complex reasoning and tool use)
• Output/coordination jobs: 5 minutes (straightforward API calls)

MCP & Tool Patterns

MCP Server Usage

Docker-based MCP Servers:

• github-mcp-server: Used in 37 workflows (97.4%)
  • Version: ghcr.io/github/github-mcp-server:v0.18.0
  • Provides GitHub API tools for agents

Imported MCP Configurations (from shared/mcp/):

MCP Server	Workflow Count	Purpose
tavily	4	Web search capabilities
serena	2	Code analysis
gh-aw	2	Workflow management tools
context7	2	Context management
brave	2	Alternative web search
ast-grep	2	AST-based code search
arxiv	2	Academic paper search
notion	1	Notion integration
microsoft-docs	1	Microsoft documentation access
markitdown	1	Markdown conversion
drain3	1	Log parsing
deepwiki	1	Deep wiki search
datadog	1	Monitoring integration

Key Finding: The github-mcp-server is nearly universal, providing core GitHub functionality to all agents.

Common Tool Allowlists

Based on Copilot CLI arguments, workflows commonly allow:

GitHub API Tools (standard across all workflows):

• Repository access: get_file_contents, search_code, list_branches
• Issue management: get_issue, list_issues, search_issues
• PR management: get_pull_request, list_pull_requests, pull_request_read
• Workflow access: get_workflow_run, list_workflows, get_job_logs
• Discussion tools: get_discussion, list_discussions
• Security: list_code_scanning_alerts, list_dependabot_alerts, list_secret_scanning_alerts

Safe Output Tools (all workflows):

• Safe outputs for controlled write operations

Web Tools (select workflows):

• Web search (Brave, Tavily)
• Web fetch capabilities

Interesting Findings

1. Highly Standardized Architecture

All 38 workflows follow a remarkably consistent 6-job architecture:

1. pre_activation: Authorization and trigger detection
2. activation: Initial response and reaction management
3. agent: Main LLM-powered reasoning and tool use
4. create_discussion/create_issue/add_comment: Safe output execution
5. detection: Post-run analysis
6. missing_tool: Missing capability reporting

This standardization suggests a well-designed framework with proven patterns.

2. Security-First Design

Every workflow implements multiple security layers:

• Read-only permissions for agent reasoning
• Write permissions isolated to specific output jobs
• Content sanitization in activation jobs
• Concurrency controls to prevent race conditions
• Missing tool reporting instead of arbitrary tool execution

3. Cache Memory Adoption

38 workflows implement cache memory file shares at /tmp/gh-aw/cache-memory/, providing persistent storage across runs for:

• Agent state and memory
• Historical data
• Learned patterns
• User preferences

This enables agents to learn and improve over time.

4. Comprehensive Observability

Workflows include extensive logging and monitoring:

• Agent stdio logs saved to /tmp/gh-aw/agent-stdio.log
• Copilot logs at /tmp/gh-aw/.copilot/logs/
• Detection jobs analyze agent performance
• GitHub step summaries provide run visibility

5. Multi-Engine Support

The repository supports multiple AI engines (Copilot, Claude, Codex, custom), with workflows designed to be engine-agnostic. This provides:

• Flexibility to use the best engine for each task
• Resilience against single-provider outages
• Ability to compare engine performance

Recommendations

1. Documentation Opportunities

Action: Create comprehensive guides for:

• The standard 6-job architecture pattern
• Safe output configuration best practices
• MCP server selection guide
• Engine selection criteria

Benefit: Lower barrier to entry for new workflow authors.

2. Optimization Potential

Finding: 94.7% of lock files exceed 100 KB in size.

Investigation: Analyze if:

• Prompts could be more concise
• Shared configurations could reduce duplication
• Large JavaScript snippets could be externalized

Potential Benefit: Faster workflow loading and reduced GitHub Actions log size.

3. MCP Server Ecosystem

Finding: Only 13 different MCP servers in use beyond github-mcp-server.

Opportunity:

• Expand MCP server catalog
• Document available MCP servers
• Create templates for common integrations

Benefit: Richer agent capabilities without custom development.

4. Schedule Optimization

Finding: Scheduled workflows concentrate around 9-10 AM UTC.

Consideration:

• Evaluate if spreading schedules reduces peak load
• Consider time zone optimization for global teams

5. Enhanced Analytics

Suggestion: Future analyses could track:

• Agent success rates (completed vs. failed runs)
• Token usage patterns across engines
• Most-used GitHub API tools
• Average execution time by workflow type
