Trigger Analysis

Most Popular Triggers

Trigger Type	Count	Percentage	Description
workflow_dispatch	48	34.5%	Manual trigger - most flexible
schedule	29	20.9%	Automated scheduling (always paired with cron)
cron	29	20.9%	Cron expression for scheduling

Trigger Combinations

The most common pattern combines workflow_dispatch with schedule/cron, allowing both manual and automated execution:

on:
  schedule:
    - cron: "0 9 * * *"
  workflow_dispatch:

This pattern appears in 29 workflows (51.8%), providing maximum flexibility.

Schedule Patterns

Popular cron schedules include:

Schedule	Frequency	Count	Description
0 9 * * *	Daily 9 AM	3	Morning reports
0 6 * * *	Daily 6 AM	2	Early morning tasks
0 0 * * *	Daily midnight	2	Daily maintenance
0 0,6,12,18 * * *	Every 6 hours	5	Smoke tests/monitoring
0 2 * * 1-5	Weekday 2 AM	2	Weekday maintenance
0 6 * * 0	Sunday 6 AM	2	Weekly reports

Most frequent: Every 6 hours (5 workflows) for continuous monitoring tasks like smoke tests.

Safe Outputs Analysis

All workflows implement safe outputs to control agent actions and prevent unrestricted modifications.

Safe Output Types Distribution

Output Type	Workflows	Percentage	Use Case
create-discussion	70*	~100%	Primary output for reports/findings
create-pull-request	68*	~97%	Code changes and improvements
create-issue	66*	~94%	Bug reports and tracking
add-comment	66*	~94%	Contextual responses
update-issue	53*	~76%	Issue management
add-labels	53*	~76%	Issue classification
missing-tool	51*	~73%	Tool request reporting
create-pull-request-review-comment	51*	~73%	Code review feedback

Note: Counts may exceed 56 as workflows can have multiple safe output types configured

Common Safe Output Configurations

1. Discussion-First Pattern (Reports & Analysis):

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

Used by: daily-news, audit-workflows, lockfile-stats, etc.

2. Issue-Focused Pattern (Bug Detection):

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

3. Full-Service Pattern (Interactive Workflows):
Multiple output types enabled for comprehensive interaction.

Discussion Categories

Workflows use the "audits" category most frequently for reporting findings and analysis results.

Structural Characteristics

Job & Step Statistics

• Average Jobs per Workflow: 5.6
• Average Steps per Workflow: 57.7
• Average Steps per Job: 10.4
• Maximum Steps in Workflow: 101 (poem-bot.lock.yml)
• Minimum Steps in Workflow: 27 (test-jqschema.lock.yml)

Typical Workflow Structure

Based on median values, a representative .lock.yml file contains:

- Size: ~203 KB
- Jobs: 5-6
- Steps per job: ~10
- Total steps: ~58
- Timeout: 10 minutes
- Permissions: contents:read, actions:read
- Triggers: workflow_dispatch + schedule

Job Distribution

Jobs Count	Workflows	Common In
2 jobs	5	Minimal test workflows, firewall configs
5 jobs	24	Most common - Standard workflow pattern
6-7 jobs	21	Enhanced workflows with extra features
8+ jobs	6	Complex multi-stage workflows

Permissions Analysis

Most Common Permissions

Permission	Count	Type	Purpose
contents:read	51	Read	Repository access
actions:read	47	Read	Workflow/action metadata
pull-requests:read	14	Read	PR information
issues:read	5	Read	Issue data
discussions:read	3	Read	Discussion access
models:read	3	Read	AI model info (GitHub Models)
security-events:read	3	Read	Security scanning
discussions:write	1	Write	Output generation
id-token:write	2	Write	OIDC authentication

Permission Patterns

Security Posture: The repository follows excellent security practices:

1. Read-Heavy: 98% of permissions are read-only
2. Minimal Write: Only 1 workflow has discussions:write (for safe outputs)
3. No Dangerous Permissions: No contents:write, pull-requests:write, or other risky permissions on the workflow level
4. Principle of Least Privilege: Workflows request only necessary permissions

Timeout Configuration

Statistic	Value
Average	13.6 minutes
Median	10 minutes
Most Common	10 minutes (15 workflows)
Range	5-30 minutes

Timeout Distribution

• 5 min: 4 workflows (quick tests)
• 10 min: 26 workflows (most common)
• 15 min: 10 workflows
• 20 min: 11 workflows
• 30 min: 3 workflows (complex analysis)

AI Engine Analysis

Engine Distribution

Engine	Count	Percentage	Use Cases
Copilot	35	62.5%	General workflows, smoke tests
Claude	21	37.5%	Complex analysis, report generation

Engine Selection Patterns

• Copilot: Preferred for standard operations, testing, monitoring
• Claude: Used for tasks requiring deeper analysis, creative output (poem-bot), comprehensive reports

Tool & MCP Server Patterns

MCP Server Usage

MCP Server	Workflows	Purpose
mcp__github	52	92.9% - GitHub API operations
mcp__playwright	2	3.6% - Browser automation
mcp__context7	1	1.8% - Context understanding
mcp__arxiv	1	1.8% - Academic research
mcp__deepwiki	1	1.8% - Deep knowledge retrieval

Key Finding: Near-universal adoption of the GitHub MCP server (52/56 workflows) for repository operations.

Tool Configuration Patterns

• GitHub MCP Tools: 52 workflows (92.9%)
• Web Tools (WebFetch/WebSearch): 21 workflows (37.5%)
• Standard Tools: All workflows include core tools (Bash, Read, Write, Edit, Grep, Glob)

Concurrency Management

100% of workflows use the standard gh-aw-pattern concurrency group:

concurrency:
  group: gh-aw-${{ github.workflow }}-${{ github.event.issue.number || ... }}
  cancel-in-progress: false

This ensures workflows don't interfere with each other while allowing parallel execution across different triggers.

Interesting Findings

1. Consistency is King

The repository demonstrates remarkable consistency:

• 57% of files are within a narrow 200-300 KB range
• 43% use exactly 10-minute timeouts
• 100% use the same concurrency pattern
• 93% use the GitHub MCP server

2. Safety-First Design

Every workflow implements multiple layers of safety:

• Read-only permissions by default
• Explicit safe outputs configuration
• No direct write access to code
• Outputs channeled through safe mechanisms

3. Flexibility Through Triggers

85% of workflows support both scheduled and manual execution, providing excellent operational flexibility.

4. Balanced Engine Selection

The 62/38 split between Copilot and Claude suggests thoughtful engine selection based on task requirements rather than dogmatic adherence to a single engine.

5. Outliers Tell Stories

• poem-bot.lock.yml (364 KB, 101 steps, 14 jobs): Most complex workflow, likely for creative AI generation
• test-*.lock.yml files (~80 KB): Minimal testing infrastructure
• q.lock.yml (300 KB): Likely a general-purpose query/question-answer agent

Recommendations

1. Consider Timeout Optimization

With 46% of workflows using 10-minute timeouts, monitor actual runtimes to identify opportunities for:

• Reducing timeouts for quick tasks (save costs)
• Increasing timeouts for workflows that frequently timeout

2. Document Engine Selection Criteria

Create guidelines for when to use Copilot vs. Claude based on the observed patterns to help future workflow authors.

3. Standardize Safe Output Patterns

The variety of safe output configurations suggests potential for standardization into 3-4 common templates:

• Report-only (discussion)
• Interactive (issue/comment)
• Code-change (PR)
• Comprehensive (all outputs)

4. Monitor Growth Trends

Track these metrics over time:

• Average file size (complexity indicator)
• Step count trends (efficiency indicator)
• Engine distribution (cost/performance balance)

5. Leverage Shared Configurations

With 93% using GitHub MCP, consider:

• Shared MCP configuration templates
• Common tool allowlists
• Standard permission sets

Methodology

Data Collection

• Tool: Python 3 + Bash scripts
• Parsing: Regex-based extraction + JSON parsing
• Files Analyzed: 56 .lock.yml files
• Cache Memory: Scripts persisted to /tmp/gh-aw/cache-memory/scripts/

Analysis Approach

1. File enumeration and size measurement
2. YAML structure parsing via regex (avoiding full YAML parse for reliability)
3. Statistical aggregation using Python collections and statistics modules
4. Pattern identification through frequency analysis

Data Quality

• Coverage: 100% of lock files parsed successfully
• Accuracy: Cross-validated with multiple extraction methods
• Freshness: Analysis reflects repository state as of 2025-10-29
