What it does
Simplify is an agent skill from codewhale-hq/Codewhale. Improve clarity and reduce needless complexity after behavior is understood; preserve behavior and keep cleanup separate from correctness fixes.
Its SKILL.md is about 160 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Open-source coding agent for your terminal, built in Rust and on a journey of continuous community improvement. Issues and PRs welcome. The licence is MIT.
Example prompts
- “/simplify”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Confirm current behavior with tests or reproduction.
- Reduce complexity in small, reviewable steps.
- Keep behavior-preserving verification green.
What it can do on your machine
Read from SKILL.md and the folder at commit ad333fd. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Simplify loads about 155 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 57 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); files beside SKILL.md are not scanned.

Simplify
When to use
Use after behavior is understood and the user wants clarity or less complexity.
Non-goals
- Do not mix cleanup with speculative refactors that change behavior.
- Do not “simplify” by deleting necessary safety checks.
Workflow
- Confirm current behavior with tests or reproduction.
- Reduce complexity in small, reviewable steps.
- Keep behavior-preserving verification green.

Questions about Simplify
What does Simplify do?
Improve clarity and reduce needless complexity after behavior is understood; preserve behavior and keep cleanup separate from correctness fixes. Simplify is an agent skill from codewhale-hq/Codewhale. Improve clarity and reduce needless complexity after behavior is understood; preserve behavior and keep cleanup separate from correctness fixes.
How do I install Simplify in Claude Code?
Run `npx skills add codewhale-hq/Codewhale --skill simplify -a claude-code`. Or copy the skill folder (crates/tui/assets/skills/simplify in codewhale-hq/Codewhale) into .claude/skills/simplify in your project. Claude Code loads it when a task matches its description.
How do I install Simplify in Codex?
Run `npx skills add codewhale-hq/Codewhale --skill simplify -a codex`. Or copy the skill folder (crates/tui/assets/skills/simplify in codewhale-hq/Codewhale) into .agents/skills/simplify in your project. Codex loads it when a task matches its description.
Can I use Simplify 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 codewhale-hq/Codewhale --skill simplify -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/simplify, .gemini/skills/simplify, .github/skills/simplify and .opencode/skills/simplify in your project.
What does Simplify need to run?
SKILL.md names no scripts, command-line tools or credentials: Simplify is instructions for the agent only.
Does Simplify 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 Simplify 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. Review the folder before installing.
What licence does Simplify use?
Simplify is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Simplify use?
About 155 tokens (SKILL.md is roughly 620 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 Simplify?
Skills that share tags, products or a category with Simplify: Refactor Method Complexity Reduce (github/awesome-copilot, 40k stars), Simplify (asgeirtj/system_prompts_leaks, 69k stars), Simplified English (paperclipai/paperclip, 98k stars) and Reduced Motion (thedaviddias/Front-End-Checklist, 74k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Simplify?
codewhale-hq (a GitHub organization) maintains it in codewhale-hq/Codewhale, which has 41,067 GitHub stars. The repository holds 63 skills in this directory. The repository was last updated on October 7, 2026.
