PR command surface — @gittensory review / pause / resume / resolve / help / configuration / explain

Phase 2 — Interactive control & issue intelligence

Context

Maintainers can re-run via a checkbox and act via MCP, but there's no conversational PR command surface. We already have role-based command authorization (src/settings/command-authorization.ts) and agent actions (src/settings/agent-actions.ts), plus the plan-command handler shape (src/review/planner.ts).

Goal

A @gittensory <command> PR/issue-comment command surface.

Requirements

• Commands: review/re-review, pause/resume, resolve, help, configuration (show effective resolved config), explain <finding>. Route through command-authorization (maintainer/collaborator/author/confirmed-miner roles + per-command overrides).
• Hard constraint: commands NEVER flip the gate to advisory or bypass the one-shot disposition; pause/resume affect only auto-review, not gate enforcement. Respect the autonomy dials + agent execution mode (paused/dry-run/live).
• Reuse the maybeProcessPlanCommand handler shape in the issue-comment/PR-comment flow.

Deliverables

• Command parser + handlers + authorization wiring + tests; help text; docs.

Expected outcome

• Maintainers control the agent inline without the dashboard; faster iteration.
