Remove timeout requirement for strict mode and set default timeout to 20 minutes

Remove timeout requirement for strict mode and set default timeout to 20 minutes

Based on the problem statement, I have successfully completed:

• Understand the current strict mode implementation
• Remove timeout requirement from strict mode validation
• Update strict mode validation function to skip timeout check
• Update tests that verify timeout requirement in strict mode
• Update documentation in docs/src/content/docs/reference/frontmatter.md to remove timeout requirement
• Update documentation in docs/src/content/docs/guides/security.md to remove timeout requirement
• Review workflow files - timeouts are kept for operational reasons (cost control)
• Run tests to ensure changes work correctly
• Run code review and address any issues
• Run make agent-finish for final validation
• Set default timeout to 20 minutes for agentic workflows
• Move default timeout to constant in constants.go

Changes Made:

Code Changes:

• Removed validateStrictTimeout() function call from validateStrictMode() in pkg/workflow/strict_mode.go
• Removed the entire validateStrictTimeout() function implementation (lines 36-82)
• Updated tests in pkg/workflow/strict_mode_test.go:
  • TestStrictModeTimeout: Now tests that timeout is NOT required and is still valid when specified
  • TestStrictModeFromFrontmatter: Updated to expect success without timeout
  • TestStrictModeIsolation: Updated to expect success for strict workflow without timeout
  • TestCLIStrictFlagTakesPrecedence: Updated to test write permission error instead of timeout error

Default Timeout Changes (per user request):

• Added DefaultAgenticWorkflowTimeoutMinutes constant to pkg/constants/constants.go (value: 20)
• Updated pkg/workflow/tools.go: Changed to use constant instead of hardcoded value
• Updated pkg/workflow/claude_engine.go: Changed to use constant instead of hardcoded value
• Updated pkg/workflow/copilot_engine.go: Changed to use constant instead of hardcoded value

Documentation Changes:

• Updated docs/src/content/docs/reference/frontmatter.md:

  • Removed "Timeout Required" from the list of strict mode requirements (requirement rejig docs #1)
  • Renumbered remaining requirements (1-4 instead of 2-5)
  • Removed timeout_minutes: 10 from the example strict mode workflow
  • Removed "Cost-sensitive workflows where timeout enforcement is critical" from use cases
  • Updated default timeout from 15 to 20 minutes

• Updated docs/src/content/docs/guides/security.md:

  • Removed "Timeout Required" from strict mode enforcement list
  • Removed timeout_minutes: 10 from example
  • Removed "Cost Control" bullet from benefits section
  • Removed reference to "and timeouts" in one sentence

Workflow Files:

• Reviewed all 20 .github/workflows/*.md files with strict mode
• Left timeout_minutes in place where specified, as they serve operational cost control purposes (not just for strict mode compliance)

Testing & Validation:

• ✅ All strict mode tests pass (6 test functions with multiple subtests)
• ✅ All unit tests pass (7.1s)
• ✅ All integration tests pass
• ✅ Code formatting validated (make fmt)
• ✅ Linter passes with no issues (golangci-lint)
• ✅ Build successful
• ✅ Verified default timeout is 20 minutes when not specified
• ✅ Verified constant is properly used across all files
• ✅ No breaking changes to existing functionality

Summary:

• timeout_minutes is now optional in strict mode workflows, though it can still be specified for operational cost control purposes
• Default timeout increased from 5 minutes to 20 minutes for agentic workflows when not explicitly specified
• Default timeout value is now centralized in a constant for easier maintenance

Original prompt

Remove timeout requirement for the scrict mode.
Review documentation that use timeout in frontmatter and remove it if not necessary.
