Fix error pattern false positives in workflow validation#1501
Merged
Conversation
Add \b word boundaries to error patterns that match "error" to prevent false positives when "error" appears as part of other words (e.g., "error-pattern-safety.instructions.md"). This fixes the issue where the repo-tree-map workflow was incorrectly flagged with errors because filenames containing "error" were being matched by overly broad regex patterns. Changes: - Updated copilot_engine.go error patterns to use \berror\b - Updated claude_engine.go error patterns to use \berror\b - Updated codex_engine.go error patterns to use \berror\b - Recompiled all workflows with updated patterns Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>

Problem
The error validation step in agentic workflows was incorrectly flagging false positives when workflow output contained filenames or text with "error" as a substring. For example, the repo-tree-map workflow was failing validation because its output included filenames like
error-pattern-safety.instructions.md.The error patterns used regex like
(?i)error.*permission.*deniedwhich would match any line containing "error" followed anywhere later by "permission" and "denied", even when "error" appeared as part of a filename rather than as an actual error message.Solution
Updated error patterns across all three AI engines (Copilot, Claude, and Codex) to use word boundaries (
\berror\binstead oferror) for patterns that should only match actual error messages, not arbitrary text containing the word "error".Changed patterns:
(?i)error.*permission.*denied→(?i)\berror\b.*permission.*denied(?i)error.*unauthorized→(?i)\berror\b.*unauthorized(?i)error.*forbidden→(?i)\berror\b.*forbidden(?i)error.*access.*restricted→(?i)\berror\b.*access.*restricted(?i)error.*insufficient.*permission→(?i)\berror\b.*insufficient.*permission(?i)error.*token.*invalid→(?i)\berror\b.*token.*invalidImpact
This fix ensures error validation correctly distinguishes between:
"ERROR: permission was denied","Error: unauthorized access""error-pattern-safety.instructions.md","The error handling code"All 64 workflows have been recompiled with the updated error patterns.
