dev-review

A workflow for planning and reviewing code changes between Claude Code and Codex CLI, two coding-agent tools. The plan is exchanged for refinement before the final version is executed in the repository.

In plain words
What is it for?
Use it to create a code-change plan, have another agent challenge or clarify it, refine the plan, execute the approved work, and verify the result.
Why use it?
It provides a structured review loop before code is changed, helping resolve disagreements or unclear requirements early. It also supports verification after execution.

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 B, and why

dev-review scanned grade B with 1 finding 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 796 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/dev-review - Plan-Bounce-Execute Workflow

Automates the workflow of composing a code plan with one AI, bouncing it between agents for refinement using [CONTESTED]/[CLARIFY] markers, then having one agent execute the final plan into code. Replaces manual copy-paste between Claude Code and Codex.

Use /co-evolution for general questions, ideas, arguments, prompt refinement, or document bounces. Use /dev-review only when the intended deliverable is a repo change or code-focused verification workflow.

For the detached flavor — the session plans and reviews while Codex executes in the background and the session is woken at gates instead of babysitting — use /codex-build (skills/codex-build/). It kicks the standalone runner with --preset codex-build (Opus plans at high, Codex executes at xhigh, Opus reviews at max; --verify on, bounces 2, revise-loop 1) and applies a schema-bound ACCEPT / REVISE / ESCALATE gate. /dev-review is the interactive single-session loop; /codex-build is the same pipeline run detached.

When --live is enabled on Windows, each Codex pass runs in a visible PowerShell window so the user can watch progress in real time. The handoff contract stays file-based: prompts are written to disk, Codex writes the final message to disk, and Claude Code reads the resulting artifact before continuing.

The workflow has three phases:

  1. Compose - One agent creates the initial plan/approach
  2. Bounce - The plan document bounces between agents, each editing it directly
  3. Execute - The designated agent writes the final code from the refined plan

Step 1: Parse Arguments

Parse $ARGUMENTS for:

/dev-review [--composer opus|codex] [--executor opus|codex] [--bounces N|auto] [--verify] [--worktree] [--model MODEL] [--skip-plan] [--plan-only] [--live] <task description>

Defaults:

  • --composer opus (Opus creates the initial plan)
  • --executor codex (Codex writes the final code)
  • --bounces auto (bounce until convergence — zero [CONTESTED] and zero [CLARIFY] markers — up to a max of 6 passes. If not converged after 6, stop and ask the user to arbitrate the remaining markers. Use --bounces N to override with a fixed count.)
  • --verify if set, adds a final code review pass after execution
  • --model overrides Codex model
  • --worktree creates isolated worktree
  • --skip-plan jumps straight to code execution (backward compat with old behavior)
  • --plan-only stops after the bounce phase, outputs the refined plan
  • --live opens visible Windows terminal windows for Codex passes; if unavailable, warn once and fall back to the current headless behavior
  • Remaining text = task description

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.

dev-review is a skill published in the GitHub repository alanshurafa/co-evolution (3 stars, last pushed 3d ago), licensed MIT. It adds 176 tokens to every session and 7,773 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
