Is the Project Planner skill free?

Yes. The skill itself is free from adrianpuiu/claude-skills-marketplace. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Project Planner SkillProof Score?

8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 2/5.

How do I install Project Planner?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Project Planner with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 8.4/10
Tested: Jul 13, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · a7a8fab

Generated planning docs for a toy task-tracker app: the skill version numbered every requirement (REQ-1..4) with SHALL/WHEN/IF acceptance criteria and traced every implementation task back to a requirement ID, while the unguided baseline was a plain bullet list an AI coder would have to interpret loosely. Docs score got knocked down because the README's 'python scripts/generate_project_docs.py' quick-start and the bundled references/domain-templates.md are never actually invoked by SKILL.md's own instructions.

What Project Planner does

Establishes Claude as a Project Architect and produces three linked planning documents: a requirements doc with SHALL-style acceptance criteria, a design doc with component maps and data flow, and a hierarchical, requirement-traced implementation plan. Triggers when starting a new project, writing specs, designing system architecture, or breaking work into implementable tasks.
