What it does
Plan is an agent skill from aiskillstore/marketplace. Plan lifecycle management for Codex plans stored in $CODEXHOME/plans (default ~/.codex/plans). Use when a user asks to create, find, read, update, delete, or manage plan documents for implementation work or overview/reference documentation.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `scripts/create_plan.py`, `scripts/list_plans.py` and `scripts/plan_utils.py`).
It sits in Agent Workflows. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- A user asks to create
- Manage plan documents for implementation work
- Overview/reference documentation
Example prompts
- “/plan”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Find/list: discover plans by frontmatter summary; confirm if multiple matches exist.
- Read/use: validate frontmatter; present summary and full contents.
- Create: inspect repo read-only; choose plan style (implementation vs overview); draft plan; write to plans directory only.
- Update: load plan; revise content and/or description; preserve frontmatter keys; overwrite the plan file.
- Delete: confirm intent, then remove the plan file if asked.
What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. 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/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python
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
Plan loads about 1.4k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 518 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 518 words (~1,378 tokens).
“Create and manage plan documents on disk. Plans stored on disk are markdown files with YAML frontmatter and free-form content. When drafting in chat, output only the plan body without frontmatter; add frontmatter only when stashing to disk. Support both…”

When should I use Plan?
Plan fits situations like: A user asks to create; manage plan documents for implementation work; overview/reference documentation.
How do I install Plan in Claude Code?
Run `npx skills add aiskillstore/marketplace --skill plan -a claude-code`. Or copy the skill folder (skills/benderfendor/plan in aiskillstore/marketplace) into .claude/skills/plan in your project. Claude Code loads it when a task matches its description.
How do I install Plan in Codex?
Run `npx skills add aiskillstore/marketplace --skill plan -a codex`. Or copy the skill folder (skills/benderfendor/plan in aiskillstore/marketplace) into .agents/skills/plan in your project. Codex loads it when a task matches its description.
Can I use Plan in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aiskillstore/marketplace --skill plan -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/plan, .gemini/skills/plan, .github/skills/plan and .opencode/skills/plan in your project.
What does Plan need to run?
Going by SKILL.md and its folder, Plan needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
Does Plan access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Plan safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Plan use?
No licence was found for Plan or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Plan use?
About 1.4k tokens (SKILL.md is roughly 5.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Plan?
Skills that share tags, products or a category with Plan: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 296k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
