What it does
Control Structure Optimization is an agent skill from kitchen-engineer42/pdf2skills. Provides a systematic checklist for optimizing control structures (loops, conditionals, control flow) to create self-documenting, maintainable code. Use this skill when writing new control logic, refactoring existing code, or conducting code reviews to minimize complexity and improve readability.
Its SKILL.md is about 790 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 review, Plain language and style rules and Refactoring. The repository describes itself as: Convert a book into skills directly callable to Claude Code.
When your agent uses it
- Writing new control logic
- Refactoring existing code
- Conducting code reviews to minimize complexity and improve readability
Example prompts
- “Use the control-structure-optimization skill to provide a systematic checklist for optimizing control structures (loops, conditionals, control flow)…”
- “/control-structure-optimization”
Workflow steps
8 steps, taken from the step headings in SKILL.md.
- Nominal Path Clarity
- Statement Grouping
- Routine Encapsulation
- Normal Case Priority
- Structural Simplicity
- Single-Function Loops
- Nesting Minimization
- Boolean Expression Simplification
What it can do on your machine
Read from SKILL.md and the folder at commit 0d70065. 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
Control Structure Optimization loads about 785 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 372 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 372 words (~785 tokens).
“Use this checklist to evaluate and improve control structures in your code. Apply these principles when writing or reviewing any control flow logic including loops, conditional statements, and branching logic.”
