9 Best Claude Prompt Templates for Developers (Token-Saving Daily Pack)

Abdulrahman Masoud — Thu, 15 Jan 2026 10:06:48 +0000

Claude is insanely useful for coding — but if you use it like a chat buddy (small tweaks, endless back-and-forth), you'll burn your usage fast.

This post is a copy/paste pack of prompt templates I use daily to get high-quality output in fewer messages.

Golden rule:

Claude = the brain (big moves)

Your IDE (Cursor/VSCode) = the hands (small edits)

How to Save Tokens With Claude (Quick Rules)

Before the templates, here are the rules that make them work:

One prompt = one feature (avoid "and also… and also…")
Ask for PATCHES / diffs, not full files
Use phases: plan first → code second → review last
Paste only what matters: 3–8 files max, or small snippets

1) The Daily “Build a Feature” One-Shot (Most Used)

Use this when you want Claude to implement a feature end-to-end with minimal back-and-forth.

You are a senior full-stack engineer.

Project: [name + stack]
Goal: Implement feature: [feature name]

Context (only what matters):
- Tech: [frameworks/libs]
- Relevant files: [list 3–8 file paths]
- Current behavior: [1–2 sentences]
- Expected behavior: [1–2 sentences]
- Constraints: [performance, RTL, no deps, etc.]

Task:
1) Propose the simplest plan (5–8 steps).
2) Produce code as PATCHES grouped by file:
   - File: path/to/file
   - Patch: only changed/added lines (no full file unless necessary)
3) Provide a short manual test checklist.

Output rules:
- No long explanations
- Ask at most 2 questions ONLY if blocking
- Prefer minimal diffs over rewrites

2) “Plan First, Stop” (Token Saver for Big Work)

Use this before a large feature to avoid wasting tokens generating code in the wrong direction.

Act as a senior engineer.

I want to implement: [feature]
Stack: [stack]

First: produce ONLY
1) Architecture / approach
2) File list (new/changed)
3) Data flow
4) Edge cases
5) Risks

STOP after planning and ask: "Continue to patches?"
Rules: no code in this phase.

3) Debug in One Pass (No Endless Chat)

This template forces Claude to rank likely causes and give you the fastest confirmation tests.

You are a senior debugger. Solve in one pass.

Problem:
- Error: [paste error]
- Where: [route/action/job]
- When: [steps to reproduce]
- Expected: [1 sentence]
- What I tried: [bullets]

Relevant code (smallest snippet + file path):
[paste]

Logs (only last relevant lines):
[paste]

Deliver:
1) Root cause (1–2 sentences)
2) Minimal fix as patches by file
3) Why it works (max 5 bullets)
4) Fast verification steps (max 5)

Rules:
- Do not ask for more info unless absolutely required
- If multiple causes, rank them + give a quick test for each

4) Refactor With Guardrails (Small, Safe Diffs)

Use this when a file is messy but you can’t risk breaking behavior.

You are a senior engineer. Refactor with minimal risk.

Target:
- File/module: [path]
- Objective: [readability/performance/structure]
- Non-goals: [do NOT change behavior, public API, output HTML, etc.]

Constraints:
- Keep diff small
- No new dependencies
- Maintain existing function signatures

Deliver:
1) Refactor plan (max 6 steps)
2) Patch per file (only changed lines)
3) Verification checklist

5) Code Review (Strict + Actionable)

Use this to get meaningful review output + small fixes without dumping your whole repo.

Act as a strict code reviewer.

Context:
- Stack: [stack]
- Code style goals: [simplicity, performance, readability]
- Constraints: [no new deps, etc.]

Review these files/snippets:
[Paste or list file + snippet]

Deliver:
- Top issues ranked by severity (max 10)
- Minimal patches for top 3 issues
- Optional improvements (max 5)
Rules: no long explanations.

6) “Generate Scaffolding Only” (When You Don’t Want Full Code Yet)

This is perfect for avoiding huge token usage on implementations you may rewrite anyway.

You are generating scaffolding only.

Project: [name]
Feature: [name]

Deliver ONLY:
1) Folder/file structure
2) Interfaces/contracts
3) Controller/service skeletons
4) TODO markers (clear next steps)

Rules:
- No full implementations
- Each file max ~60 lines
- Output per file

7) Implement UI Component Pack (Design → Components)

Great when you’re converting a design into consistent UI building blocks.

Act as a UI engineer.

Goal: Build a reusable component pack for:
- [buttons, inputs, cards, modals, alerts...]

Design requirements:
[paste]

Constraints:
- Accessibility required (ARIA/keyboard)
- Mobile-first
- RTL-ready if needed
- Keep it framework-native (no heavy libs)

Deliver:
1) Component list + props
2) File outputs per component
3) Usage examples (short)
Rules: avoid repeated code blocks.

8) “Work in Phases” (Stops Claude From Spamming Output)

Use this when you want Claude to produce controlled outputs.

Work in phases. After each phase, STOP and ask "Continue?"

Phase 1: Plan + file list
Phase 2: Core patches
Phase 3: Edge cases + polish
Phase 4: Tests/checklist

Start with Phase 1 only.

9) Convert Requirements → Implementation Checklist (No Code)

Useful when you want clarity before spending tokens on code generation.

What are pointers in golang

Abdulrahman Masoud — Sun, 01 May 2022 13:25:03 +0000

Hi, I'm Abdulrahman, and I'm glad to share this blog, in this blog we will talk about Pointers in golang.

Pointer is a variable that references a memory location where a value is stored so before digging deeper into pointers we should know what are variables and how variables work.

What are variables

Variables are placeholder of the information to store the value for any data type you need like string, integr, boolen, float, etc..
basically, if we have a string we can assign it to any variable, and then we can access this string by the name of the variable declared, so how variable stored this string
every variable you assign it, so when you assign a variable it will be assigned to a memory address in the computer.

Let's deg deeper into pointers

Pointers is a way to store the memory address for any type of variable.

Why we need to use pointers?

first we need to know how variables works like we explain above is the name given to a memory location is pointing to the stored data
we need pointers to store the memory address of another variable to can access the value of this memory location to make any operation on this value you can change the value for this address, note: when you try to change this value by memory address you actually replace the old value by the new value.

Syntax to declare a pointers

first, you need to know the two important operators we will use in pointers

*: this asterisk operator used to declare pointer variable
&: this and to return the address of a variable you are added a pointer on it

so to declare a pointer, we need to use * and assign this asterisk to the data type in the variable declared, and you need to use & before the new variable to get the memory address for the pointed variable

Examples

Example 1

package main

import "fmt"

func main() {
    var name *string
    me := &name
    fmt.Println(name) // Result nil
    fmt.Println(me)   // Result 0xc00000e028
}

in the above example, we declare a new variable name and make it a pointer by adding * to the data type and declare another variable
me and make it pointed to a memory address for variable name by adding & to the name variable, so let's see the results
result for variable name is nil why nil? because we didn't assign any value for it
and the result for variable me is 0xc00000e028 what is this hash? this is the address for a location in memory, why return this result? because we declare variable me as a reference for variable name and this reference pointed to the memory address for name variable in the memory location.

Example 2

package main

import "fmt"

func main() {
    var x int = 100
    var y *int = &x
    *y = 50
    fmt.Println(x) //Result 50
    fmt.Println(y) //Result  0xc0000ba000
}

in the above example, we declare a variable x and assign 100 value to it, and declare another variable y it's a pointer and its value of it is a reference to variable x
and assign a 50 for a pointer of y variable,
so why the result of x is 50? because we add the reference of variable x to pointer y here y is pointed a memory address of x if we change the value of y or x it will change both because these two variables pointed to the same memory address
if we assigned a new value for x it will change the value for *y like this example

package main
import "fmt"
func main() {
    var x int = 100
    var y *int = &x
    *y = 50
    x = 25
    fmt.Println(*y) //Result 25
    fmt.Println(y) //Result  0xc0000ba000
}

here result will be 25 why? because the variables has the same memory address.

Note: when we need to print a value for a pointer we need to print it using * like we did above with variable y *y and if we tried to print it without add * before it will print a memory address for this variable

Example 2 (Pointer to a Struct Syntax)

pointer to a struct is just like any other pointer.

package main

import "fmt"

type User struct {
    FirstName string
    LastName  string
}

func main() {
    var user *User
    abdulrahman := User{"Abdulrahman", "Masoud"}
    user = &abdulrahman

    fmt.Println(&user)          //0xc00000e028
    fmt.Println(user.FirstName) //Abdulrahman
}

in the above example we declare a struct User it has FirstName and LastName and in main function and add a new var user to assign a pointer of struct User
and add a new user called abdulrahman to make a new user and tell user var is equal a reference of abdulrahman

Example 3 (Pointer to a Struct)

We can simply pass a pointer to a struct in the function and then manipulate the struct using the function via the pointer. Let’s see how one would do that.

package main

import "fmt"

type User struct {
    FirstName string
    LastName  string
}
func change(user *User) {
    user.LastName = "Masoud"
}
func main() {
    user := User{"Abdulrahman", "Salah"}
    fmt.Println(user) //{Abdulrahman Salah}
    change(&user)
    fmt.Println(user) //{Abdulrahman Masoud}
}

in above example we declare a new function change and pass a pointer of User as argument and then use it to change the LastName
What happens is that,the pointer changes it at the original value.

This is extremely useful since we want to change the original rather than a copy of it.

Summary

Variables are placeholder of the information to store the value for any data type.
Pointer is a variable that references a memory location.
when you assign a variable it will be assigned to a memory address
we need pointers to store the memory address of another variable
when you try to change the value by memory address you actually replace the old value by the new value.
* asterisk operator used to declare pointer variable
& and operator to return the address of a variable you are added a pointer on it
pointer to a struct is just like any other pointer.

What are methods in golang

Abdulrahman Masoud — Thu, 14 Apr 2022 22:53:10 +0000

Hi, I'm Abdulrahman I'm glad to share this blog, in this blog we will talk about methods in golang.
so first we must know Go does not have classes because it doesn't support Object-oriented programming.

What is Object-oriented

Object-oriented its way to allow programmers to declare a function inside the class definition. Go doesn't allow us to do that, we have to declare a method on a struct via a special syntax

because Golang doesn't support Object-oriented programming but Golang has Methods.

What is Methods in golang

Method is a function with a special receiver argument and this method can access the properties of the receiver. Receiver here can be type struct or non type struct like(int-string-etc...)

let's see the syntax with example

Syntax

func (r ReceiverType) funcName(parameters) (result){/*code*/}

this above example is ho we define a method for any Receiver here is => YourStruct
Let’s see a full example to understand how to define a method on a type and how to invoke such a method

package main

type User struct { //define a struct
    FirstName string
    LastName  string
}

in above example we defined a struct has FirstName-LastName and if we want to get the FullName we can get them like this:

package main

import "fmt"

type User struct { 
    FirstName string
    LastName  string
}

func main() {
    user := User{
        "Abdulrahman",
        "Masoud",
    }
    fmt.Print(user.FirstName+" "+user.LastName)
    // Result => Abdulrahman Masoud
}

but in GoLang you are allowed to define a method whose receiver is your struct like we say before.
This receiver is accessible inside the method as shown in the below example:

package main

import "fmt"

type User struct { //define a struct
    FirstName string
    LastName  string
}

// GetFullName method to get full name
func (u User) GetFullName() string {
    return u.FirstName + " " + u.LastName
}

func main() {
    user := User{
        "Abdulrahman",
        "Masoud",
    }
    fmt.Print(user.GetFullName())
    // Result => Abdulrahman Masoud
}

In above example we defined a struct that has the inputs that I need and second, we defined a GetFullName method and add a receiver for this method (u User) => this is the receiver of method

Let's define non type struct

Syntax

package main

import "fmt"

type Age int

func (a Age) GetAgeAfterTenYears() int {
    return int(a + 10)
}

func main() {
    age := Age(22)
    fmt.Print(age.GetAgeAfterTenYears())
    // Result => 32
}

In above example we defined an Age type it's not a struct type its non type struct like we say before Receiver here can be type struct or non type struct

End of blog

Summary

Go does not have classes because it doesn't support Object-oriented
Golang doesn't support Object-oriented programming but Golang has Methods
Method is a function with a special receiver
Receiver is type
Receiver can be type struct or non type struct
method can access the properties of the receiver
