Independently validate a pull request from another AI session before a human merge. Enforce CI/head-SHA triage, an isolated review worktree, repository gates, negative-path proof for guards, reproduced findings, a three-tier verdict, cold fix handoff, delta review, and an explicit merge-or-hold outcome. Use for delegated builder PR review, fix delta review, or agent-work validation. Do not use for your own uncommitted diff or a plain human-authored PR without delegation context.

Execute a rejected pull request's fix round as a cold implementer session. A reviewer found defects and wrote a handoff comment with numbered findings and C0–C7 checkpoints; work that punch list under invariants enforced by a PreToolUse hook and gate scripts — reproduce the reviewer's red before touching the tree, stay inside the handoff's fence, one `F<n>:` commit per finding, record the output of every acceptance criterion, post a closing report, and STOP without merging. Use whenever a review comes back with changes requested and you are handed the PR plus its findings. Do not use it to author the original plan (that is `delegate`), to build a slice from a plan with no prior review (that is `implement-workflow`), or to review someone else's PR (that is `review-workflow`).

Create Web, GUI, or Terminal design specifications in story, standalone, or extract mode from a customizable brief, brand, and visual direction; generate design.md, implementation artifacts, and web artifacts when the selected target is Web. Use through /create-design when a project needs a design source of truth or an existing mockup must be extracted.
Create Web, GUI, or Terminal design specifications in story, standalone, or extract mode from a customizable brief, brand, and visual direction; generate design.md, implementation artifacts, and web artifacts when the selected target is Web. Invoke explicitly with $spec-driven-design.
Run the delegation loop: act as a standing architect/reviewer who surveys ideas into merit-ranked plans, pins design decisions with the maintainer (AskUserQuestion), records maintainer-pinned plans in evidence docs, generates full-fidelity zero-ambiguity build prompts for cold AI builder sessions (Claude Code / Codex / other), resolves builder HALTs, reviews the resulting PRs against watchpoints declared at prompt time, and records outcomes. Language- and project-agnostic; per-project specifics live in .delegate/config.md. Also covers greenfield bootstrap (idea → repo → first slice) and the design-session leg (mockup prompts for Claude Design, mockup review with numbered rulings). Invoke via `/delegate PHASE`, or when the user asks to "generate a build prompt for another session", "pin a design", "generate a mockup prompt", "review the mockup", "review the builder's PR", or run any part of this loop.
Execute a cold implementation session from an externally authored plan, handoff, task-register entry, or build prompt. Enforce slice arming, consultation, AskUserQuestion HALTs, test-first commit order, repository gates, one worktree/branch/PR, cold-review handoff, and stop-without-merge. Use when the user asks to implement or execute a plan written elsewhere. Do not use to author plans or resolve builder HALTs (`delegate`), review completed PRs (`review-workflow`), or apply a review punch list (`fix-workflow`).
