Autonomous plan executor. Reads a multi-stream plan, orchestrates the entire execution by dispatching background Agent-tool instances — one primary agent per eligible stream, plus verification and remediation agents per stream. Monitors status files, spawns next waves when streams complete, and reports final results. User-invocable via /dominion command. The user's alternative to manually running /stream in separate terminals. Triggers: dominion, auto-execute, run all streams, execute plan.

Legion execution discipline: orchestrator-driven parallel agent waves within a single stream. Decomposes stream tasks into TDD-phased waves, crafts focused minimal-context prompts, dispatches background agents, verifies between waves, and assembles results. Loaded by /stream when a stream has legion annotation. Triggers: legion, wave, parallel agents, orchestrator, dispatch.

Multi-stream plan execution coordinator. Tracks stream progress across sessions, manages dependencies, auto-loads relevant skills, and enforces verification gates. User-invocable via /stream command. Triggers: stream, next stream, stream status, claim stream, continue plan.

Session bootstrap for every new conversation. Offers four paths: plan, no-plan, talk-it-out, or design. Planning path writes a plan to docs/plans/, validates against quality standards, optionally runs triumvirate, then recommends clearing context and spinning up implementation sessions. Design path front-loads UI/UX decisions via ui-ux-pro-max before planning. User-invocable via /summon command. No prompts or props required.

Actions: plan, build, create, design, implement, review, fix, improve, optimize, enhance, refactor, and check UI/UX code.

Senior-engineer sanity discipline for readability, maintainability, and abstraction quality. Identifies monolithic files, repeated inline logic, weak helper boundaries, and code that technically works but is calcifying. Use during implementation, cleanup, refactoring, or review when code should feel senior-maintainable rather than merely functional.

Testability discipline for application code. Identifies when logic should be extracted into pure helpers, when routes/pages/components are carrying too much domain work, and when code needs seams for focused unit tests. Use when reviewing maintainability, refactoring for better tests, or validating whether code is easy to verify without brittle integration-heavy coverage.

Codex-side plan refinement before execution begins. Refines plans for clarity, stream quality, realistic dependencies, abstraction sanity, reuse of existing components/patterns, verification coverage, and better compression without losing important intent. Use when reviewing a plan that exists without a status file or when the user wants Codex to improve a plan before /stream or /dominion.

Findings-first validation workflow modeled on strong Codex manual review. Verifies the project, reviews changed code plus surrounding context for correctness and maintainability, fixes approved issues, re-verifies, and only then commits. Use for final validation streams or when the user wants a more rigorous manual audit than the classic /review flow.
