Critical Error Patterns

P1: Copilot Custom Agents API Unavailable 🚨

Pattern:

Request to GitHub API at (redacted)
failed with status 404

Impact: 10+ workflow runs
Affected Workflows: Tidy, Mergefest, CLI Version Checker, and others
Root Cause: Copilot custom agents API endpoint returning 404

Recommendation:

• Verify if the Copilot custom agents API has been deprecated or moved
• Update endpoint URL if changed
• Add fallback behavior when custom agents unavailable

Related Runs:

• §18808915922
• §18809411897
• §18816852099
• §18819663584

P2: MCP Response Size Exceeds Token Limit ⚠️

Pattern:

MCP tool "list_pull_requests" response (153731 tokens) exceeds maximum allowed tokens (25000)

Impact: 5+ workflow runs
Affected Tools: list_pull_requests, search_pull_requests, list_issues
Root Cause: Tools called without pagination parameters on large datasets

Recommendation:

• Always specify perPage parameter (e.g., perPage: 10-30)
• Use pagination for large result sets
• Add automatic pagination in MCP server layer

Related Runs:

• §18769519086
• §18813905477

P3: Firewall Rule Parser Errors 🔧

Pattern:

Invalid rule format: shell(cat)
Invalid rule format: github(list_workflow_run_artifacts)

Impact: 2 workflow runs
Affected Workflows: Smoke Copilot Firewall, Artifacts Summary
Root Cause: Firewall rule parser cannot handle parentheses in tool names

Recommendation:

• Update firewall rule parser to properly escape/handle parentheses
• Use different delimiter or format for tool-specific rules
• Add validation and better error messages

Related Runs:

• §18812954043
• §18813782251

P4: Copilot Permission Denials 🔐

Pattern:

Permission denied and could not request permission from user

Impact: 20+ tool calls across multiple runs
Affected Workflows: Mergefest, Tidy
Root Cause: Copilot engine requires explicit user permission for certain operations

Recommendation:

• Review Copilot permission model
• Add auto-approval for safe operations (git status, formatting)
• Provide better guidance on permission requirements

Related Runs:

• §18816855563
• §18818254898
• §18820623510

P5: Git/PR Operations Failures 📝

Pattern:

push_to_pull_request_branch failed
create_pull_request failed

Impact: 8+ workflow runs
Affected Workflows: Tidy, Changeset Generator, Mergefest
Root Cause: Various - merge conflicts, permissions, git state issues

Recommendation:

• Add retry logic with exponential backoff
• Better error messages with actionable guidance
• Pre-flight checks before git operations

Related Runs:

• §18802773502
• §18808915922
• §18809411897
• §18821224601

Affected Workflows Analysis

High-Failure Workflows (>25% failure rate)

Workflow	Runs	Failures	Rate	Primary Issue
CLI Version Checker	2	2	100%	Copilot API 404, NPM fetch failures
Artifacts Summary	3	2	66.7%	Firewall rule parser, agent failures
Mergefest	7	3	42.9%	Permission denials, git conflicts
Smoke Claude	6	2	33.3%	MCP config errors, token limits
Tidy	20	6	30%	PR creation failures, Copilot API 404
Smoke Copilot Firewall	4	1	25%	Firewall rule format errors
Smoke Copilot	5	1	20%	Agent failures

Stable Workflows (0% failure rate)

The following workflows had 100% success rate:

• Smoke Codex (5 runs)
• Smoke OpenCode (5 runs)
• Documentation Unbloat (4 runs)
• Smoke Detector (4 runs)
• Plan Command (3 runs)
• Q (3 runs)
• Copilot Agent PR Analysis (2 runs)

Additional Issues

MCP Configuration Errors

• Run: §18769543228
• Issue: "Invalid MCP configuration" during agent startup
• Impact: Agent failed to initialize

GitHub API Permission Errors

• Pattern: "403 Resource not accessible by integration"
• Impact: Limited but blocks certain operations
• Recommendation: Review GitHub App permissions

Network Connectivity Issues

• Pattern: ICMPv6 unreachable to 2606:4700::6810:123
• Impact: Firewall proxy connectivity
• Recommendation: Monitor network infrastructure

External Service Dependencies

• CLI Version Checker: NPM registry fetch failures
• Issue: "Unexpected token 'C', 'Content ty'... is not valid JSON"
• Recommendation: Add timeout and error handling for external services

Performance Metrics

Note: Token usage and cost metrics are not being properly collected in most run summaries. This appears to be a data collection issue.

• Total Tokens: 0 (not collected)
• Total Cost: $0 (not collected)
• Average Duration: Varies by workflow
• Longest Run: Multiple 8+ minute runs

Recommendation: Investigate why token usage metrics are not being captured.

Recommendations
