What it does
Codex Plan Review is an agent skill from PiLastDigit/TRIP-workflow. Iterative Codex CLI review of a planning document
Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including scripts (for example `scripts/_common.sh`, `scripts/key.sh` and `scripts/reset.sh`).
It works with Bash. The repository describes itself as: Simple & BS-free Dev Workflow for AI Coding Agents.
Example prompts
- “/codex-plan-review”
Requirements
- A Bash shell
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Parse $ARGUMENTS: extract action (reset/show/auto) and plan path.
- Auto — try start.sh first (exit code 2 = thread exists -> use resume.sh)
- Reset: bash .claude/skills/codex-plan-review/scripts/reset.sh
- Show: bash .claude/skills/codex-plan-review/scripts/show.sh
- Parse trailing tag
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 6 files in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
bashbrew
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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 Plan Review loads about 903 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 374 words of instructions outside code blocks.
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 374 words (~903 tokens).
