Permission Patterns

Most Common Permissions

Permission	Count	Type	Usage
contents:read	644	Read	Repository content access
discussions:write	269	Write	Create/update discussions
issues:write	268	Write	Create/update issues
pull-requests:write	240	Write	Create/modify PRs
pull-requests:read	130	Read	Read PR data
issues:read	128	Read	Read issue data
contents:write	77	Write	Commit changes
actions:read	63	Read	Workflow metadata
discussions:read	35	Read	Read discussions
security-events:read	16	Read	Security scanning

View Permission Analysis

Permission Philosophy:

• Read-heavy: Most jobs use read permissions (contents:read appears 644 times)
• Targeted writes: Write permissions are granted only where needed
  • discussions:write (269) - for audit reports and summaries
  • issues:write (268) - for creating findings and recommendations
  • pull-requests:write (240) - for automated fixes
• Security-conscious: Only 77 instances of contents:write (11% of workflows)

Permission Distribution by Job:

• Activation jobs: Minimal (contents:read only)
• Agent jobs: Read-only (contents, issues, PRs, discussions)
• Safe output jobs: Targeted writes (one permission per output type)

This follows the principle of least privilege - agents read and analyze, safe outputs handle writes.

Timeout Configuration

• Workflows with timeout: 142/143 (99.3%)
• Average timeout: 21.8 minutes
• Maximum timeout: 180 minutes (3 hours)
• Minimum timeout: 5 minutes

Timeout Distribution:

• 5-15 minutes: ~45 workflows (quick analysis)
• 15-30 minutes: ~85 workflows (standard analysis)
• 30-60 minutes: ~10 workflows (deep analysis)
• 60+ minutes: ~2 workflows (comprehensive research)

Insight: The 22-minute average timeout suggests most workflows complete agent execution and safe output processing within this window, balancing thoroughness with resource efficiency.

MCP Server Patterns

The analysis detected MCP server usage, though extraction was limited due to complex configuration patterns. The most commonly detected pattern was:

MCP Pattern	Count	Context
token	143	Authentication tokens for MCP gateway

Note: All workflows use the MCP gateway architecture with standardized server configurations including:

• github: GitHub API access via MCP
• safeoutputs: Safe output processing via MCP HTTP server
• Additional servers: Varies by workflow (tavily, brave-search, chroma, arxiv, etc.)

MCP Architecture Observations

All 143 workflows follow a consistent MCP architecture:

1. MCP Gateway Setup: All workflows configure an MCP gateway with:

   • Port allocation
   • API key generation
   • Domain configuration

2. Standard MCP Servers:

   • github: Present in all workflows for GitHub API access
   • safeoutputs: Present in all workflows for output handling

3. Specialized MCP Servers (detected in subsets):

   • tavily: 6 workflows (web search)
   • brave-search: 4 workflows (alternative web search)
   • chroma: 1 workflow (vector database)
   • arxiv: 4 workflows (academic research)
   • notion: 2 workflows (Notion integration)

The MCP server pattern provides a clean abstraction for tool access while maintaining security boundaries.

Interesting Findings

1. Universal Issue Interface: 100% of workflows support issue-based triggering, establishing issues as the universal interface for agentic workflows. This creates a consistent user experience where any workflow can be invoked by creating/commenting on an issue.

2. Business Hour Optimization: 72% of workflows have scheduled triggers, with strong clustering around business hours (11 AM - 4 PM weekdays). This suggests workflows are designed to provide timely insights when developers are most active.

3. Consistent Size Profile: 84.6% of workflows fall in the 50-100 KB range, indicating a standardized structure and complexity level. The uniformity suggests successful pattern reuse and architectural consistency.

4. Conservative Timeouts: With an average timeout of 22 minutes and 99% of workflows having explicit timeouts, the repository demonstrates careful resource management. Most workflows complete well within their allocated time.

5. Safety-First Architecture: The separation of read permissions (agent job) from write permissions (safe output jobs) appears in all workflows, demonstrating a consistent security-first approach where agents analyze and recommend, but only approved safe outputs can modify resources.

6. Massive Step Count: With 10,252 total steps across 143 workflows, the average workflow has ~72 steps. This high granularity suggests thorough validation, setup, execution, and cleanup processes in each workflow.

Historical Trends

Comparing with previous analyses:

• 2025-11-22: 91 workflows
• 2025-12-09: 111 workflows
• 2025-12-15: 237 workflows (spike - possibly different analysis scope)
• 2026-01-28: 141 workflows
• 2026-01-29: 143 workflows (current)

Growth Pattern:

• +57% growth from Nov 22 to Jan 29 (91 → 143 workflows)
• +2 workflows in the last day, suggesting active development

Trend Analysis: The steady growth indicates:

• Expanding automation coverage
• Growing confidence in the agentic workflow pattern
• Successful pattern replication across different use cases

Recommendations

1. Size Optimization: With 15 workflows over 100 KB, consider investigating if these could be modularized or if they represent genuinely complex use cases that warrant the size.

2. Schedule Distribution: Consider distributing scheduled workflows more evenly throughout the day to avoid potential resource contention during peak hours (11 AM - 4 PM).

3. Timeout Analysis: The 2 workflows with 60+ minute timeouts should be analyzed to understand if they're experiencing performance issues or legitimately require extended execution time.

4. MCP Server Documentation: Create a catalog of available MCP servers and their use cases to help workflow authors discover and reuse existing integrations.

5. Pattern Library: With 143 workflows following consistent patterns, create a template library highlighting the most successful configurations:

   • Standard daily weekday (0 13 * * 1-5 + issues + workflow_dispatch)
   • Quick analysis (15 min timeout, 6 jobs)
   • Comprehensive analysis (45 min timeout, 8+ jobs)

6. Trigger Standardization: With 100% issue support but varying other triggers, document the decision criteria for when to add schedule vs. PR vs. discussion triggers.
