flow-next-plan-review is a skill for Claude Code, Codex from gmickel/flow-next. It costs 32 tokens per session (1,850 once invoked), scanned A, original, MIT.

A detailed review of a software specification or implementation plan, performed through a selected review backend. The backend is the configured tool or process that performs the review.

In plain words
What is it for?
Use it to inspect a plan or specification and return review findings through the configured Codex, Copilot, Cursor, host, or other supported backend.
Why use it?
It helps find unclear requirements, missing cases, and weak technical decisions before implementation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

flow-next-plan-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan Review Mode

Workflow is backend-split. Read workflow.md for common orchestration and backend resolution, then read ONLY the file matching the selected review backend:

Do not load the other backend files. BACKEND=none and explicit --review=export terminate from the common workflow without loading any backend file.

Conduct a John Carmack-level review of spec plans.

Role: Code Review Coordinator (NOT the reviewer) Backends (branch on the common workflow's RP_ELIGIBLE probe):

  • When RP_ELIGIBLE=1: RepoPrompt (rp), Codex CLI (codex), GitHub Copilot CLI (copilot), Cursor CLI (cursor), Claude Code CLI (claude), or host-native (host)
  • When RP_ELIGIBLE=0: Codex CLI, GitHub Copilot CLI, Cursor CLI, Claude Code CLI, or host-native — rp remains accepted explicitly but errors at runtime

Preamble — execute common routing exactly once

Read and execute workflow.md Phase 0 once. It defines $FLOWCTL, probes RepoPrompt eligibility, parses an explicit --review mode before configured-backend resolution, resolves SPEC_ID, and handles ASK, none, and export. Never invoke flowctl review-backend a second time.

When RP_ELIGIBLE=0, never steer the user toward rp. An explicit --review=rp, FLOW_REVIEW_BACKEND=rp, or review.backend=rp remains valid input and fails through the rp runtime check.

Backend Selection

Priority (first match wins):

  1. --review=rp|codex|copilot|cursor|claude|host|export|none
  2. Per-spec default_review
  3. FLOW_REVIEW_BACKEND
  4. .flow/config.json review.backend
  5. Error — no auto-detection

Configured values accept backend[:model[:effort]]; cursor takes a model but no effort, claude takes claude[:<model>[:<effort>]], and host, rp, and none are bare-only. export is a one-off mode, never a configured backend.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
