What it does

Codex Code Review is an agent skill from PiLastDigit/TRIP-workflow. Iterative Codex CLI code review against an implementation plan

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including scripts (for example `scripts/reset.sh`, `scripts/resume.sh` and `scripts/show.sh`).

It sits in Development, covering Code review and Planning. It works with Bash. The repository describes itself as: Simple & BS-free Dev Workflow for AI Coding Agents.

When your agent uses it

  • Tasks that involve Code review
  • Tasks that involve Planning

Example prompts

  • “/codex-code-review”

Requirements

  • A Bash shell

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Parse $ARGUMENTS: extract action (reset/show/auto) and target.
  2. Auto — try start.sh first (exit code 2 = thread exists -> use resume.sh)
  3. Reset: bash .claude/skills/codex-code-review/scripts/reset.sh
  4. Show: bash .claude/skills/codex-code-review/scripts/show.sh
  5. Parse trailing tag
  6. Resume after addressing findings for incremental re-review.

What it can do on your machine

Read from SKILL.md and the folder at commit 3e5d4f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 4 files in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • git
    • bash
    • brew

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Codex Code Review loads about 1.2k tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 480 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 480 words (~1,155 tokens).

“Iterative code review via Codex CLI on uncommitted changes. Codex reads the plan and runs git status -s / git diff HEAD to inspect the change set.”
