Is the Plan Create skill free?

Yes. The skill itself is free from markshust/hcf. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Plan Create SkillProof Score?

8.0/10 — installs cleanly 3/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 3/5.

How do I install Plan Create?

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 Plan Create 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: Works with setup
Score: 8.0/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 91270e8

Ran a real feature request through it end-to-end: it produced a proper _plan.md (scope in/out, success criteria, task table) plus a numbered task file with atomic test-description requirements, versus a baseline that just started coding off a flat 5-bullet list. Real friction though: it's built as a Claude Code plugin, not a standalone skill — a bare cp -r of skills/plan-create alone leaves dangling references (a code-standards.md the body cites doesn't exist anywhere in the repo, and its hook-discovery mechanism needs the plugin's agents/ dir two levels up from SKILL.md, which a lone skill copy won't have).

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 3/5
Triggers reliably 5/5
Output vs. baseline 9/10
Docs & honesty 3/5

What Plan Create does

Runs codebase discovery, asks scope/data-model/architecture clarifying questions, then writes a _plan.md plus numbered task files with test-description requirements and a dependency graph for autonomous TDD workers. Triggers on aspirational build requests ('let's build', 'I want an app that...'), capability lists, and explicit build verbs; explicitly skips quick bug fixes, single-line changes, and 'run/implement the plan' requests (routed to plan-orchestrate instead).

How to install Plan Create

git clone https://github.com/markshust/hcf
cd hcf
mkdir -p ~/.claude/skills
cp -r skills/plan-create ~/.claude/skills/plan-create

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Plan Create

/plan-create Turns a feature request into a TDD task-and-dependency plan for autonomous parallel execution.

It also activates on plain-language prompts like these:

I want an app where users can track books they're currently reading.
Let's build a user authentication system with JWT from scratch.
Users should be able to sign up, log in, and reset their password.
