Systematically analyze project structure, dependencies, and patterns for team onboarding and codebase understanding. 3-tier mode — quick (inline) or deep/thorough (parameterized lens analysts + a completeness-critic pass + synthesis via a plugin-shipped native Workflow segment, opt-in gated), with incremental analysis support. Use when joining a new project or generating reproducible codebase documentation.
Opt-in gated 3-Phase orchestrator (Plan -> Gate -> Generate -> Verify -> Evaluate). Runs plugin-shipped native Workflow segment scripts on the workflow path (ultracode or --mode opt-in) with schema-validated returns; inline single path otherwise. Use for development tasks (feature work, bug fixes, maintenance) AND non-development tasks that benefit from structured planning, implementation, and 3-layer review. (formerly /workflow)
Automated test generator with mutation-based quality verification — single (inline) or multi (parallel coverage analysts + propose-only mutation skeptics via plugin-shipped native Workflow segments, opt-in gated; test generation and mutation execution stay orchestrator-inline). Generates unit and integration tests, runs them, and validates meaningfulness via simplified mutation testing. Supports coverage-gap detection and regression test generation from debug reports.
Systematic, bias-free code review for PRs, branches, or file changes. Quick mode (1 agent, 5-perspective checklist, inline) or deep/thorough modes (2-3 specialist reviewers + adversarial cross-verification + synthesis via a plugin-shipped native Workflow segment, opt-in gated). Optional --comment (inline PR comments) and --fix (gated apply). The deeper, bias-reduced complement to the built-in /code-review. (formerly /code-review)
Execute framework/library version upgrades, language transitions, and dependency replacements with staged, verified execution — single (inline) or multi (parallel external-research + codebase-impact analysts + synthesis and an isolated evaluator via plugin-shipped native Workflow segments, opt-in gated). WebSearch-based migration guide research, per-step test verification, and session recovery.
Safe, behavior-preserving code structure improvement with 3-tier mode — single (inline) or multi/comprehensive (2-3 analysts + cross-critique + synthesis via plugin-shipped native Workflow segments, opt-in gated). Atomic changes, test after each step, stop on failure. Use when improving code structure without changing behavior.
Hypothesis-driven debugger with mandatory executable verification. Classifies build/compile vs runtime/logic errors, attempts reproduction, generates falsifiable hypotheses verified by code search, git history, and test execution. Quick mode (orchestrator only, inline) or deep mode (2 specialist analysts + adversarial cross-verification via a plugin-shipped native Workflow segment, opt-in gated). Use when facing a bug, unexpected behavior, or error that needs systematic root cause analysis.
Requirements specification writer with multi-round Q&A discovery. Transforms vague ideas into structured specs compatible with /harness input. Modes — quick (orchestrator only, inline) / deep (4 analysts + Critic via plugin-shipped native Workflow segments, opt-in gated). Use when you need a well-defined spec before starting implementation.
