Installation
A skill is a folder with a SKILL.md file. Pick your agent and run the commands in a terminal (macOS, Linux or Git Bash on Windows) from your project root.
Copy the prompt into Claude, Codex or another assistant: it will review the skill and install it for you.
Install the “project-planner” skill from mozgi.io (https://mozgi.io/skills/project-planner/) for me. 1. Download the archive: https://mozgi.io/skills/project-planner/download If it fails, take the skill folder from the source: https://github.com/modimihir07/agentic-os/tree/main/skills/project-planner 2. Read SKILL.md and the other files. Check the skill is safe: no hidden commands, no sending data elsewhere, no scripts doing something other than described. If anything looks suspicious, stop and tell me. 3. Put the “project-planner” folder into your agent's skills folder: .claude/skills/ for Claude Code, .agents/skills/ for Codex, .cursor/skills/ for Cursor, .gemini/skills/ for Gemini CLI. Inside the project if we are in one, otherwise in the home folder (~/.claude/skills/ etc.). 4. Make sure <skills folder>/project-planner/SKILL.md exists. 5. Briefly tell me what this skill does and offer to try it on my task. If you cannot do a step yourself, tell me what to click or type.
git clone --depth 1 --branch main https://github.com/modimihir07/agentic-os.git /tmp/agentic-os mkdir -p .claude/skills cp -r /tmp/agentic-os/skills/project-planner .claude/skills/project-planner
Restart Claude Code — the skill appears in the list; call it manually with /project-planner. For all projects use ~/.claude/skills.
git clone --depth 1 --branch main https://github.com/modimihir07/agentic-os.git /tmp/agentic-os mkdir -p .agents/skills cp -r /tmp/agentic-os/skills/project-planner .agents/skills/project-planner
Codex looks for skills in .agents/skills from the current folder up to the repo root; call one with /skills or $project-planner. For all projects use ~/.agents/skills.
git clone --depth 1 --branch main https://github.com/modimihir07/agentic-os.git /tmp/agentic-os mkdir -p .cursor/skills cp -r /tmp/agentic-os/skills/project-planner .cursor/skills/project-planner
Cursor picks the skill up on start; call it with “/” in Agent chat. Cursor also reads .claude/skills and .agents/skills. For all projects use ~/.cursor/skills.
git clone --depth 1 --branch main https://github.com/modimihir07/agentic-os.git /tmp/agentic-os mkdir -p .gemini/skills cp -r /tmp/agentic-os/skills/project-planner .gemini/skills/project-planner
Gemini CLI offers to activate the skill when a task matches — you approve it. For all projects use ~/.gemini/skills.

- Starting a new feature
- Planning a refactor
- Spec-driven development
- Before writing any significant code
Process
1. Brainstorm and refine requirements
2. Read standards/ for project conventions
3. Create spec document with screens and data model
4. Break into tasks (2-5 minutes each)
5. Each task has: file path, code template, verification step
6. Save spec and plan to context/
Output
Spec document + task plan + implementation order
Agent Assignment
- Primary: opencode
- Fallback: agy
Frequently asked questions
What does the project-planner skill do?
Generates detailed project implementation plans, breaking tasks into small steps with file paths, code templates, and verification steps.
How do I install project-planner?
Open the “Installation” block on this page and pick your agent — Claude Code, Codex, Cursor or Gemini CLI — for ready-made commands that copy the skill folder to the right place. Or copy the prompt from the “Via assistant” tab and let the assistant review and install the skill.
Which AI models work with project-planner?
Skills are plain Markdown instructions (the Agent Skills format), so project-planner works with any agent that reads SKILL.md: Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and more. The model loads the instructions only when a task matches the skill's description.
Is project-planner free?
The skill is published openly by modimihir07 under the MIT license. The skill itself costs nothing — you only pay your AI provider for the tokens you use.
Is it safe to install skills?
A skill is a set of instructions your agent will follow, so read SKILL.md and its companion files before installing. Scripts in the skill folder only run if your agent runs them — keep an eye on what it does and do not grant unnecessary permissions.
How is a skill different from an MCP server or a plugin?
An MCP server or plugin gives the model new tools — code that runs and returns a result. A skill gives it knowledge and process: how to approach a task, which steps to follow and what good output looks like. It needs no server or API key.
