Review And Simplify Changes
Dimillian/Skills
Review a git diff or explicit file scope for reuse, code quality, efficiency, clarity, and standards issues, then optionally apply safe Codex-driven fixes.
Run the code and documentation simplification passes together over one scope, launching every review sub-agent concurrently before applying a single round of fixes.

- Works in 2 steps: Run $simplify-code and $simplify-docs… → Fix Issues

What it does
Simplify All is an agent skill from tobihagemann/turbo. Run the code and documentation simplification passes together over one scope, launching every review sub-agent concurrently before applying a single round of fixes. Use when the user asks to "simplify all", "simplify everything", "simplify code and docs", "clean up code and docs", "run both simplify skills", or "simplify code and docs in parallel".
Its SKILL.md is about 360 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 simplification, Subagents and Refactoring. The repository describes itself as: Reusable workflows for planning, building, reviewing, and shipping with Claude Code and Codex. The licence is MIT.
When your agent uses it
- The user asks to simplify all
- Simplify everything
- Simplify code and docs
- Clean up code and docs
Example prompts
- “simplify all”
- “simplify everything”
- “simplify code and docs”
- “/simplify-all”
Workflow steps
2 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 160a0fa. 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 All loads about 357 tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 161 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-all
- description
- Run the code and documentation simplification passes together over one scope, launching every review sub-agent concurrently before applying a single round of fixes. Use when the user asks to "simplify all", "simplify everything", "simplify code and docs", "clean up code and docs", "run both simplify skills", or "simplify code and docs in parallel".
Simplify All
Step 1: Run $simplify-code and $simplify-docs Skills
Run the $simplify-code and $simplify-docs skills together, passing along any scope that was provided so both passes cover identical files.
Issue the spawn_agent calls for every review sub-agent the two skills define in one batch. Do not issue one and await its result before issuing the rest. Hold every fix for Step 2 in place of each skill's own fix step.
Step 2: Fix Issues
Once wait_agent has joined every sub-agent, aggregate the findings and apply one round of fixes, following each skill's own guidance for resolving its findings.
Once this round's fixes have landed, including any resolved at a gate, make one pass over the agents' findings: any whose verdict depended on code the fixes changed, moved, added, or deleted gets decided again against the current tree, keeping resolutions the user already chose.
Then call update_plan to mark this step completed and continue with the next step of the active workflow.
