What it does
Simplify is an agent skill from tmdgusya/engineering-discipline. Review changed code for reuse opportunities, quality issues, and inefficiencies using three parallel review agents, then fix any issues found. Triggers when the user says "simplify", "clean up the code", "review the changes", or after run-plan execution when code quality verification is needed.
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Code quality. It works with Git. The repository describes itself as: SKILL for engineering-discipline.
When your agent uses it
- The user says simplify
- Clean up the code
- Review the changes
- After run-plan execution when code quality verification is needed
Example prompts
- “simplify”
- “clean up the code”
- “review the changes”
- “/simplify”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Identify Changes
- Launch Three Review Agents in Parallel
- Fix Issues
What it can do on your machine
Read from SKILL.md and the folder at commit 137dead. 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
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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 2.8k tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 1,583 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,583 words (~2,795 tokens).
“Reviews all changed files through three parallel agents — reuse, quality, and efficiency — then fixes any issues found.”

Questions about Simplify
What does Simplify do?
Review changed code for reuse opportunities, quality issues, and inefficiencies using three parallel review agents, then fix any issues found. Simplify is an agent skill from tmdgusya/engineering-discipline. Review changed code for reuse opportunities, quality issues, and inefficiencies using three parallel review agents, then fix any issues found.
When should I use Simplify?
Simplify fits situations like: the user says simplify; clean up the code; review the changes; after run-plan execution when code quality verification is needed.
How do I install Simplify in Claude Code?
Run `npx skills add tmdgusya/engineering-discipline --skill simplify -a claude-code`. Or copy the skill folder (skills/simplify in tmdgusya/engineering-discipline) 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 tmdgusya/engineering-discipline --skill simplify -a codex`. Or copy the skill folder (skills/simplify in tmdgusya/engineering-discipline) 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 tmdgusya/engineering-discipline --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?
Going by SKILL.md and its folder, Simplify needs the command-line tools its instructions call (git).
Does Simplify access the network?
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Simplify safe to install?

What licence does Simplify use?
No licence was found for Simplify or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Simplify use?
About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
