What it does

Enforces Effective-Dart casing (UpperCamelCase types, lowerCamelCase members/constants, lowercase_with_underscores files) plus architectural role suffixes so a name or grep reveals the layer — Screen/Notifier/Repository/Dao/Service/Gateway/Failure, file=primary-declaration, units-and-semantics in identifiers, booleans as is/has/can/should assertions, no get-prefix, no Hungarian, no SCREAMING_CAPS, grouped-and-sorted imports.

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

6# Naming Conventions

8Consistent, role-carrying names make code searchable and self-explaining, and the suffix on a type declares which layer it lives in — so a reviewer, a grep, and a banned-import gate can all read the layer off the name alone. This skill is the *how*; the normative *what* is [Effective Dart](https://dart.dev/effective-dart). Never invent a house style that contradicts the language's own.

10## Non-negotiable rules
11
121. **Types are UpperCamelCase.** Classes, enums, mixins, extensions, typedefs, type parameters: TaskScreen, OrderStatus, Predicate<T>. Consistent shape makes types visually distinct from values.
132. **Members, variables, functions, and parameters are lowerCamelCase.** dueDate, loadTasks(), itemCount. It is the language default; deviating costs readers a double-take.
143. **Constants are lowerCamelCase, never SCREAMING_CAPS.** const maxItemsPerPage = 50; — not const MAX_ITEMS = 50. Dart dropped the C convention; the analyzer expects constant_identifier_names.
154. **Files, folders, libraries, and import prefixes are lowercase_with_underscores.** task_detail_screen.dart, features/task_detail/, import 'package:app_core/app_core.dart';. Cross-platform filesystems and pub demand it.
165. **File name = its primary declaration, snake_cased, one primary public type per file.** TaskNotifier lives in task_notifier.dart. No utils.dart/helpers.dart/models.dart grab-bags and no utils//common//helpers//misc/ junk-drawer folders — a reader who greps a symbol must land in the file that owns it. core/ is the *sanctioned* pure-foundation layer (value objects, Result/Failure, the Clock seam, pure calculators), not a junk-drawer — see project-structure-and-packages, which owns the layout.
176. **Acronyms longer than two letters are cased like a word.** Json, Http, Url, Api → JsonOrder, HttpClient, fromJson, imageUrl — not JSONOrder, HTTPClient. Two-letter caps-in-English acronyms may stay caps as types (ID, UI). Mixed-case acronyms are unsearchable and inconsistent.
187. **A leading underscore means library-private — use it only when you mean private.** Never prefix a public symbol with _ to "namespace" it; that makes it unusable from another file. Public (no _) is a documented contract — see dartdoc-conventions.
198. **No Hungarian / type-encoding in names.** Not strName, iCount, lstItems, userMap, nameString, itemsList. The type system already knows the type; write name, usersById, items.
209. **Full dictionary words; units and semantics live in the name.** maxItemsPerPage, retryDelaySeconds, orderTotalMinorUnits — never bare max, delay, total. Abbreviations (opt, qty, amt) are confined to the inside of one short pure function with a comment mapping them. A name that omits its unit invites a unit bug.
2110. **Booleans read as assertions.** isLoading, hasError, canSubmit, shouldRetry — not loading, error, retry. Boolean getters and methods start is/has/can/should so a condition reads like prose.
2211. **No get-prefixed accessors.** Expose dueTasks, not getDueTasks(). Dart has real getters. Functions are verb phrases (loadTasks(), scheduleReminder()); non-boolean getters are noun phrases (itemCount, nextDueDate).
2312. **Imports grouped and sorted:** dart: first, then package:, then relative — each group alphabetized, exports in their own section after imports. Let dart format plus the directives_ordering lint enforce it; never hand-fight the formatter.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈170
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
3,230
on trigger
The instruction body, read only when the skill fires.
1.7%
of a 200k window
Ten skills this size would take about 17% of the window before you open a file.
050k100k150k200k context window

3.4k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Middling. Fine to keep on in a project where you use it weekly, worth unloading in one where you never do.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

1 file, 13.6 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md13.6 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 1 file you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Naming Conventions · 3.4k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/zakariaf-naming-conventions/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/naming-conventions" ] && { [ ! -e .claude/skills/naming-conventions ] || { mv .claude/skills/naming-conventions "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/naming-conventions" .claude/skills/ && echo "Installed .claude/skills/naming-conventions"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add zakariaf/naming-conventions

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/naming-conventions/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/zakariaf-naming-conventions/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/naming-conventions" ] && { [ ! -e ~/.claude/skills/naming-conventions ] || { mv ~/.claude/skills/naming-conventions "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/naming-conventions" ~/.claude/skills/ && echo "Installed ~/.claude/skills/naming-conventions" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/naming-conventions/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
