Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install ertugrul-dmr/clean-code-skills clean-names --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/ertugrul-dmr/clean-code-skills.git skills-src && mkdir -p .claude/skills && cp -r skills-src/skills/typescript/clean-names .claude/skills/clean-names && rm -rf skills-src

Use ~/.claude/skills/ instead of .claude/skills for a personal install. The folder must contain SKILL.md.

At a glance

A skill your agent uses when naming, renaming, or fixing names of variables, functions, classes, interfaces, or modules in TypeScript.

  • Fixing names of variables
  • SKILL.md covers N1: Choose Descriptive Names, N2: Choose Names at the…, N3: Use Standard Nomenclature… and N4: Unambiguous Names, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Modules in TypeScript

What it does

Clean Names is an agent skill from ertugrul-dmr/clean-code-skills. Use when naming, renaming, or fixing names of variables, functions, classes, interfaces, or modules in TypeScript. Enforces Clean Code principles—descriptive names, appropriate length, no encodings.

Its SKILL.md is about 1k 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 TypeScript. The licence is MIT.

When your agent uses it

  • Fixing names of variables
  • Modules in TypeScript

Example prompts

  • “/clean-names”

What it can do on your machine

Read from SKILL.md and the folder at commit 1b6b3cc. 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 (its code samples are typescript).

    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

Clean Names loads about 1k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 185 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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.

Clean Names

N1: Choose Descriptive Names

Names should reveal intent. If a name requires a comment, it doesn't reveal its intent.

ts
// Bad - what is d?
const d = 86400;

// Good - obvious meaning
const SECONDS_PER_DAY = 86400;

// Bad - what does this function do?
function proc(values: number[]) {
  return values.filter((value) => value > 0);
}

// Good - intent is clear
function filterPositiveNumbers(numbers: number[]) {
  return numbers.filter((number) => number > 0);
}

N2: Choose Names at the Appropriate Level of Abstraction

Don't pick names that communicate implementation; choose names that reflect the level of abstraction of the class or function.

ts
// Bad - too implementation-specific
function getMapOfUserIdsToNames() {
  // ...
}

// Good - abstracts the data structure
function getUserDirectory() {
  // ...
}

N3: Use Standard Nomenclature Where Possible

Use terms from the domain, design patterns, or well-known conventions.

ts
// Good - uses pattern name
class UserFactory {
  create(data: unknown) {
    // ...
  }
}

// Good - uses domain term
function calculateAmortization(principal: number, rate: number, term: number) {
  // ...
}

N4: Unambiguous Names

Choose names that make the workings of a function or variable unambiguous.

ts
// Bad - ambiguous
function rename(source: string, target: string) {
  // ...
}

// Good - clear what's being renamed
function renameFile(oldPath: string, newPath: string) {
  // ...
}

N5: Use Longer Names for Longer Scopes

Short names are fine for tiny scopes. Longer scopes need longer, more descriptive names.

ts
// Good - short name for tiny scope
const total = numbers.reduce((sum, n) => sum + n, 0);

// Good - longer name for module-level constant
const MAX_RETRY_ATTEMPTS_BEFORE_FAILURE = 5;

// Bad - short name at module level
const MAX = 5;

N6: Avoid Encodings

Don't encode type or scope information into names. Modern editors make this unnecessary.

ts
// Bad - Hungarian notation
const strName = "Alice";
const arrUsers: string[] = [];
const nCount = 0;

// Good - clean names
const name = "Alice";
const users: string[] = [];
const count = 0;

// Bad - interface prefix
interface IUserRepository {
  findById(id: string): Promise<unknown>;
}

// Good - just name it
interface UserRepository {
  findById(id: string): Promise<unknown>;
}

N7: Names Should Describe Side Effects

If a function does something beyond what its name suggests, the name is misleading.

ts
const configStore = new Map<string, string>();

// Bad - name doesn't mention file creation
function getConfig(configPath: string) {
  if (!configStore.has(configPath)) {
    configStore.set(configPath, "{}"); // Hidden side effect!
  }
  return JSON.parse(configStore.get(configPath) ?? "{}");
}

// Good - name reveals behavior
function getOrCreateConfig(configPath: string) {
  if (!configStore.has(configPath)) {
    configStore.set(configPath, "{}");
  }
  return JSON.parse(configStore.get(configPath) ?? "{}");
}
