What it does
Aidd Javascript is an agent skill from paralleldrive/aidd. JavaScript and TypeScript best practices and guidance. Use when writing, reviewing, or refactoring JavaScript or TypeScript code.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Development, covering Refactoring. It works with JavaScript and TypeScript. The repository describes itself as: The standard framework for AI Driven Development. The licence is MIT.
When your agent uses it
- Refactoring JavaScript
- TypeScript code
Example prompts
- “/aidd-javascript”
What it can do on your machine
Read from SKILL.md and the folder at commit 9a7c8e3. 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
Aidd Javascript loads about 1.1k tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 522 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.

JavaScript/TypeScript guide
Act as a top-tier software engineer with serious JavaScript/TypeScript discipline to carefully implement high quality software.
Before Writing Code
- Read the lint and formatting rules.
- Observe the project's relevant existing code.
- Conform to existing code style, patterns, and conventions unless directed otherwise. Note: these instructions count as "directed otherwise" unless the user explicitly overrides them.
Principles
- DOT
- YAGNI
- KISS
- DRY
- SDA - Self Describing APIs
- Simplicity - "Simplicity is removing the obvious, and adding the meaningful."
- Obvious stuff gets hidden in the abstraction.
- Meaningful stuff is what needs to be customized and passed in as parameters.
- Functions should have default parameters whenever it makes sense so that callers can supply only what is different from the default.
Constraints {
Be concise.
Favor functional programming; keep functions short, pure, and composable.
Favor map, filter, reduce over manual loops.
Prefer immutability; use const, spread, and rest operators instead of mutation.
One job per function; separate mapping from IO.
Obey the projects lint and formatting rules.
Omit needless code and variables; prefer composition with partial application and point-free style.
Chain operations rather than introducing intermediate variables, e.g. [x].filter(p).map(f)
Avoid loose procedural sequences; compose clear pipelines instead.
Avoid class and extends as much as possible. Prefer composition of functions and data structures over inheritance.
Keep related code together; group by feature, not by technical type.
Put statements and expressions in positive form.
Use parallel code for parallel concepts.
Avoid null/undefined arguments; use options objects instead.
Use concise syntax: arrow functions, object destructuring, array destructuring, template literals.
Avoid verbose property assignments. bad: const a = obj.a; good: const { a } = obj;
Assign reasonable defaults directly in function signatures.
const createExpectedUser = ({ id = createId(), name = '', description = '' } = {}) => ({ id, name, description });
Principle: SDA. This means:
Parameter values should be explicitly named and expressed in function signatures:
Bad: const createUser = (payload = {}) => ({
Good: const createUser = ({ id = createId(), name = '', description = ''} = {}) =>
Notice how default values also provide hints for type inference.
Avoid IIFEs. Use block scopes, modules, or normal arrow functions instead. Principle: KISS
Avoid using || for defaults. Use parameter defaults instead. See above.
Prefer async/await or asyncPipe over raw promise chains.
Use strict equality (===).
Modularize by feature; one concern per file or function; prefer named exports.

NamingConstraints {
Use active voice.
Use clear, consistent naming.
Functions should be verbs. e.g. increment(), filter().
Predicates and booleans should read like yes/no questions. e.g. isActive, hasPermission.
Prefer standalone verbs over noun.method. e.g. createUser() not User.create().
Avoid noun-heavy and redundant names. e.g. filter(fn, array) not matchingItemsFromArray(fn, array).
Avoid "doSomething" style. e.g. notify() not Notifier.doNotification().
Lifecycle methods: prefer beforeX / afterX over willX / didX. e.g. beforeUpdate().
Use strong negatives over weak ones: isEmpty(thing) not !isDefined(thing).
Mixins and function decorators use with${Thing}. e.g. withUser, withFeatures, withAuth.
Avoid ALL_CAPS for constants. Since we use functional programming, there's no need for a hard distinction between constants and variables.
}
Comments { Favor docblocks for public APIs - but keep them minimal. Ensure that any comments are necessary and add value. Never reiterate the style guides. Avoid obvious redundancy with the code, but short one-line comments that aid scannability are okay. Comments should stand-alone months or years later. Assume that the reader is not familiar with the task plan or epic. }
