2. Discussion vs Issue Creation: Create discussion (32.4%) and create issue (32.4%) are equally popular, suggesting workflows are split between using GitHub Discussions for broader conversations and Issues for actionable tracking.

3. PR Automation: 24.3% of workflows can create pull requests autonomously, demonstrating significant code modification capabilities.

4. Multi-modal Outputs: Many workflows combine multiple safe output types, enabling agents to interact through various GitHub interfaces (comments + issues + discussions).

Structural Characteristics

Job Complexity

• Average Jobs per Workflow: 6.46 jobs
• Average Steps per Workflow: 58.16 steps
• Average Steps per Job: 9.00 steps
• Job Range: 3-14 jobs
• Step Range: 29-98 steps

Distribution Analysis

Jobs per Workflow	Count
3 jobs	2 (test workflows)
4 jobs	1
6 jobs	20 (most common)
7 jobs	7
8 jobs	2
9 jobs	2
14 jobs	1 (poem-bot - outlier)

Average Lock File Structure

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

• Size: ~200 KB
• Jobs: ~6-7 jobs (pre_activation, activation, agent, detection, safe outputs, missing_tool)
• Steps per Job: ~9 steps
• Total Steps: ~58 steps
• Permissions: Empty top-level permissions ({}), read-all for agent job
• Triggers: workflow_dispatch + optional schedule
• Timeout: ~10-15 minutes for agent execution
• MCP Servers: github + safe-outputs (mandatory), optional: tavily, notion, slack

Structural Insights

1. Standard Pattern: The 6-job pattern appears in 54% of workflows, representing a canonical agentic workflow structure:

   • pre_activation → activation → agent → detection/safe outputs → missing_tool

2. Complexity Outliers:

   • poem-bot (14 jobs, 98 steps): Most complex workflow with multiple parallel output handlers
   • test-post-steps (3 jobs, 30 steps): Minimal test workflow

3. Step Efficiency: Average 9 steps per job indicates well-organized job definitions with focused responsibilities.

Permission Patterns

Permission Configuration

Permission Type	Count	Percentage
Empty top-level permissions (permissions: {})	37	100%
Agent job with read-all	35	94.6%
Agent job with no explicit permissions	2	5.4%

Security Model

Principle of Least Privilege: 100% of workflows use empty top-level permissions, restricting access by default. The agent job then explicitly grants read-all permissions (94.6% of cases), enabling agents to:

• Read repository contents
• Access GitHub API for reading issues, PRs, discussions
• Read workflow artifacts and logs

Write Operations: All write operations (creating issues, comments, PRs) are handled through safe-output MCP tools, which use separate authentication mechanisms, maintaining a security boundary between agent read access and write capabilities.

Notable Exception: Two workflows (test-jqschema, test-post-steps) don't specify read-all for the agent job, likely because they're minimal test workflows with limited requirements.

Tool & MCP Patterns

Most Used MCP Servers

MCP Server	Count	Percentage	Purpose
safe-outputs	35	94.6%	Core GitHub write operations (issues, PRs, discussions)
github	35	94.6%	GitHub API read access
tavily	5	13.5%	Web search capabilities (daily-news, research, scout)
notion	2	5.4%	Notion integration (notion-issue-summary)
brave	2	5.4%	Brave search API
slack	1	2.7%	Slack notifications

Engine Distribution

Engine Type	Count	Percentage	Workflows
GitHub Copilot	25	67.6%	Most workflows use Copilot as the agent engine
Claude	9	24.3%	smoke-claude, and Claude-specific workflows
OpenAI/Codex	1	2.7%	smoke-codex
Unknown/Other	2	5.4%	Engine not explicitly identified

Insight: GitHub Copilot dominates as the primary agent engine (67.6%), with Claude as the secondary option (24.3%). This suggests the repository is optimized for Copilot-based agentic workflows.

Common Tool Configurations

1. Core Toolset (present in ~95% of workflows):

   • Bash execution
   • GitHub API access (read/write)
   • File operations (Read, Write, Glob, Grep)
   • Safe outputs MCP server

2. Extended Toolset (present in research/web-enabled workflows):

   • Web search (Tavily/Brave)
   • Web fetch capabilities
   • External integrations (Notion, Slack)

3. Specialized Tools (workflow-specific):

   • PDF processing (pdf-summary)
   • Video analysis (video-analyzer)
   • Custom MCP servers for domain-specific tasks

Timeout Configuration

Timeout (minutes)	Count	Percentage
5 minutes	3	8.1%
10 minutes	21	56.8%
15 minutes	7	18.9%
20 minutes	6	16.2%

Average Timeout: 12.16 minutes

Analysis:

• Most workflows (56.8%) use a 10-minute timeout, balancing between execution time and resource conservation.
• Longer timeouts (15-20 minutes) are used for complex analysis workflows (e.g., scout, research).
• Shorter timeouts (5 minutes) are used for simple smoke tests or quick operations.

Interesting Findings

1. Standardization Achievement: Despite 37 diverse workflows with different purposes, there's remarkable consistency in structure:

   • 100% use empty top-level permissions
   • 94.6% use the same 6-job pattern
   • 94.6% include both github and safe-outputs MCP servers
   • 78.4% support manual workflow_dispatch triggering

2. The "Missing Tool" Pattern: 97.3% of workflows enable the missing_tool safe output, indicating a culture of continuous improvement where agents can report gaps in their capabilities back to developers.

3. Size-Complexity Correlation: There's a strong correlation between file size and structural complexity:

   • Smallest files (90-95 KB) → 3 jobs, ~30 steps (test workflows)
   • Medium files (150-200 KB) → 6 jobs, ~50-60 steps (standard workflows)
   • Largest files (250-350 KB) → 7-14 jobs, 70-98 steps (complex multi-output workflows)

4. The Poem Bot Anomaly: The poem-bot.lock.yml workflow is an outlier in multiple dimensions:

   • Largest file size (346 KB)
   • Most jobs (14)
   • Most steps (98)
   • This suggests poem-bot is either a comprehensive demonstration workflow or a highly sophisticated multi-modal agent.

5. Morning Automation Pattern: 75% of scheduled workflows run between 9-11 AM UTC, suggesting these agentic workflows are designed to provide morning briefings, daily summaries, or workday preparation tasks.

6. Workflow Dispatch Dominance: 78.4% of workflows support manual triggering, indicating that while automation is valuable, human-in-the-loop control remains a priority.

Recommendations

For Workflow Authors

1. Adopt the Standard Pattern: The 6-job pattern (pre_activation → activation → agent → detection → outputs → missing_tool) has emerged as a best practice used by 54% of workflows. New workflows should consider adopting this pattern for consistency.

2. Enable Missing Tool Reporting: If not already present, add missing_tool to your safe outputs configuration to enable agents to report capability gaps.

3. Consider Manual Triggers: 78.4% of workflows include workflow_dispatch. If your workflow might benefit from manual execution, add this trigger.

4. Optimize Timeouts: The average timeout is 12 minutes. Review your workflow's timeout settings:

   • Simple operations: 5-10 minutes
   • Standard workflows: 10-15 minutes
   • Complex analysis: 15-20 minutes

For Repository Maintainers

1. Template Workflow: Create a reference template based on the most common patterns:

   • 6 jobs (standard pattern)
   • workflow_dispatch + optional schedule
   • github + safe-outputs MCP servers
   • 10-minute timeout
   • Empty top-level permissions with read-all for agent

2. Size Guidelines: Lock files naturally range from 100-350 KB. Files outside this range may indicate:

   • <100 KB: Potentially under-specified workflows (check if instructions are sufficient)

   • 350 KB: Potentially over-complex workflows (consider splitting into multiple workflows)

3. Documentation: Document the canonical 6-job pattern and when to deviate from it (e.g., poem-bot's 14-job structure for specialized use cases).

4. MCP Server Discovery: Only 13.5% of workflows use web search (Tavily). Consider promoting web-search capabilities for research-oriented workflows.

For Future Development

1. Consolidate Schedule Times: 11 different cron schedules are in use. Consolidating to a few standard times (e.g., 9 AM, 10 AM) could simplify maintenance and reduce confusion.

2. Standardize Safe Output Combinations: Some safe output combinations appear frequently (e.g., create_discussion + missing_tool). Consider creating standard configuration presets.

3. Engine Abstraction: With 67.6% using Copilot and 24.3% using Claude, ensure workflows remain engine-agnostic or clearly document engine requirements.
