  • feat: Colored diff output in --dry-run mode (source files, complexity, scanner)
  • docs: Comprehensive troubleshooting section in README

Wave 7 — Quick Wins Bundle (7c179a0)

  • feat: oac r alias for oac run (power-user shortcut)
  • feat: Distinct exit codes for CI/CD integration:
    • 0 — all tasks succeeded or dry-run
    • 1 — unhandled error
    • 2 — config/validation error
    • 3 — every task/epic failed
    • 4 — partial success (some tasks failed)
  • feat: Resettable token counters (claudeCounter.reset(), codexCounter.reset()) for correctness in long-lived processes
  • feat: Progress percentages on long operations (file analysis, task estimation, epic execution)

Wave 6 — Single-Command Pipeline (156c7d2)

  • feat: oac run now performs the full scan → analyze → execute pipeline in one command
  • ux: Clarified distinction between oac scan (discover tasks) and oac analyze (build context)

Wave 5 — Run Module Decomposition (aea2760)

  • refactor: Decomposed the 1,692-line run.ts monolith into src/cli/commands/run/ with 8 focused modules:
    • index.ts — command definition and option parsing
    • pipeline.ts — top-level orchestration
    • epic.ts — epic-based execution flow
    • task.ts — single-task execution
    • retry.ts — --retry-failed pipeline
    • output.ts — summary rendering and JSON output
    • validation.ts — config and input validation
    • types.ts — shared types, exit codes, ConfigError

Wave 4 — Timeout, Completion, & Retry (cb1af6c)

  • feat: PR creation timeout (prevents hanging on GitHub API issues)
  • perf: Replaced hand-rolled runWithConcurrency with PQueue for bounded parallelism
