Ran a real design-to-code mini task: the skill's plan step surfaced an ambiguous design decision (mutate vs. return-new) and asked before writing, which the unguided baseline silently assumed instead — but for a 2-file task the mandatory plan/approval/report ceremony is disproportionate overhead.

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

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 6/10
  • Docs & honesty 5/5

What Code Generator does

Structures code implementation work into phases, each with an operation table (create/modify/delete), token-cost estimate, and before/after diff preview, and requires explicit user approval before writing files. Triggers when implementing a new module from a design doc, adding a feature to existing code, or generating a structured multi-file implementation.

How to install Code Generator

git clone https://github.com/Dqz00116/skill-lib
mkdir -p ~/.claude/skills
cp -r skill-lib/code-generator ~/.claude/skills/code-generator

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

Commands — how to trigger Code Generator

  • /code-generator Turns a design doc into a phase-by-phase implementation plan with cost estimates and an approval gate.

It also activates on plain-language prompts like these:

  • Turn this design doc into a phased implementation plan with costs
  • Show me a diff preview before you generate any of these files
  • Plan out the multi-file implementation for this new module

Frequently asked questions

Is the Code Generator skill free?
Yes. The skill itself is free from Dqz00116/skill-lib. SkillProof publishes the install command and an independent test verdict at no cost.
Does Code Generator work with Claude Code?
We tested it with Claude Code 2.x (agent harness) on Jul 16, 2026. Verdict: Tested · Works. Ran a real design-to-code mini task: the skill's plan step surfaced an ambiguous design decision (mutate vs. return-new) and asked before writing, which the unguided baseline silently assumed instead — but for a 2-file task the mandatory plan/approval/report ceremony is disproportionate overhead.
What is the Code Generator SkillProof Score?
8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 6/10, docs & honesty 5/5.
How do I install Code Generator?
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 Code Generator 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.
