ha

Multi-pass adversarial verification harness that guarantees the accuracy of a change before it ships. Use whenever you need high confidence that an implementation is correct, safe, and complete — before opening a PR, before approving a review, or whenever a change touches risky surface area such as auth, crypto, data migration, money, or external input.

Address review feedback on a PR and push the fixes back, rigorously — feedback is evaluated against the code, not obeyed blindly. Use after /ha:review-pr requests changes, or to act on human review comments on a PR. Invoke explicitly with /ha:apply-feedback. Requires the superpowers plugin.

Reclaim worktrees after features land — remove every merged worktree in the repo (ha/sa/ca and any other, regardless of location) and delete their merged branches. Use once a feature PR is merged. Safe by default — never removes a worktree with uncommitted changes, never deletes an unmerged branch, and never touches the main checkout (it removes the current worktree too, but only if its branch is merged). Invoke explicitly with /ha:clean-worktrees.

Standards for writing and reviewing code — quality, test rigor, security, and codebase consistency. Use whenever implementing, changing, or reviewing code, or when checking a PR or diff for bugs, missing test coverage, vulnerabilities, missed propagation, or style drift.

Implement an approved ha plan for ONE feature, thoroughly, and open a PR. Use after /ha:plan (or with a plan file or task) when you want the feature built with ha's full rigor rather than a quick hand-off — for a non-trivial change you intend to review and merge. Stops at PR; run /ha:review-pr for the independent review. Invoke explicitly with /ha:implement. Requires the superpowers plugin.

Merge a reviewed PR after confirming it is genuinely ready — open, not draft, no changes requested, green CI, up to date with base, no unresolved blocking feedback. Use once /ha:review-pr approves a feature's PR. Refuses to merge on red checks, changes-requested reviews, or conflicts. Invoke explicitly with /ha:merge-pr.

Plan ONE feature thoroughly before any code. Use when starting a feature in ha and you want a rigorous, vetted plan you approve before implementation — for a non-trivial change where getting the design and the tests right up front matters more than speed. Accepts a GitHub issue, spec, @file, or free-text task. Invoke explicitly with /ha:plan; hands off to /ha:implement. Requires the superpowers plugin.

Resolve merge conflicts between a feature branch and its base branch, in an isolated worktree, parallelizing across files with subagents when 3+ files conflict. Use when a PR or feature branch is behind or conflicting with the base branch and you want the conflicts resolved, verified, and pushed. Invoke explicitly with /ha:resolve-conflicts.

Critically review a PR for correctness, security, architecture, testing, and codebase consistency — an independent, adversarial second opinion, not a rubber stamp. Use to review an ha feature's PR before merging, or any PR you want high confidence in; pass --comment to post findings inline. Invoke explicitly with /ha:review-pr.
