Gsd Plan Review Convergence

Flow: Skill("gsd-plan-phase") → Agent→Skill("gsd-review") → check unresolved HIGH + actionable non-HIGH → Skill("gsd-plan-phase --reviews") → Agent→Skill("gsd-review") → ... → Converge or escalate

Replaces gsd-plan-phase's internal gsd-plan-checker with external AI reviewers (codex, gemini, etc.). Plan-phase runs inline (bare Skill at depth 0) so it can spawn gsd-planner/gsd-plan-checker at depth 1. Review runs inside an isolated Agent (gsd-review is a Bash leaf — no sub-agents needed). Orchestrator only does loop control.

Orchestrator role: Parse arguments, validate phase, run plan-phase inline (Skill at depth 0), spawn an Agent for gsd-review, check unresolved HIGH and actionable non-HIGH counts, stall detection, escalation gate.

Flags:

• --codex — Use Codex CLI as reviewer (default if no reviewer flag given AND review.default_reviewers is unset; otherwise review.default_reviewers wins per ADR-0011 — #2315)
• --gemini — Use Gemini CLI as reviewer
• --agy / --antigravity — Use Antigravity CLI as reviewer (successor to the discontinued Gemini CLI)
• --claude — Use the agent CLI as reviewer (separate session)
• --opencode — Use OpenCode as reviewer
• --ollama — Use local Ollama server as reviewer (OpenAI-compatible, default host http://localhost:11434; configure model via review.models.ollama)
• --lm-studio — Use local LM Studio server as reviewer (OpenAI-compatible, default host http://localhost:1234; configure model via review.models.lm_studio)
• --llama-cpp — Use local llama.cpp server as reviewer (OpenAI-compatible, default host http://localhost:8080; configure model via review.models.llama_cpp)
• --all — Use all available CLIs and running local model servers
• --max-cycles N — Maximum replan→review cycles (default: 3)
