The Cursor agency that gets a stalled codebase live
Cursor writes code fast. It does not choose your architecture, write your tests, or check what the agent changed last week. Our senior engineers work in Cursor every day. We find what blocks your release, fix it, and leave a codebase your team can run.

Definition
What is a Cursor agency?
A Cursor agency is an engineering team that builds and maintains software using Cursor, the AI code editor and coding agent from Anysphere. Its engineers direct the agent, review every change, and set up the rules, tests and permissions that keep AI-written code safe to release. The client receives working software, not tool access.
As a Cursor development agency, HorizonLux uses the editor in its own daily work. On a stalled project we read the codebase, find where the agent’s output drifted, and repair it with tests in place.

Where projects stall
Why Cursor-built code stops short of release
Three documented failure modes. Each has a known fix.
- 01
The agent forgets your decisions
Cursor’s own docs state that models keep no memory between completions. Without project rules, each session guesses your conventions again, and the codebase fills with three ways of doing one thing.
What we do: We write scoped rules and AGENTS.md files, then remove the duplicates.
- 02
Code that runs but is not safe
Independent security testing finds that AI-written code often contains known flaws when nobody asks for security. SQL injection and cross-site scripting pass a demo and fail an audit.
What we do: We run a security review, fix the findings, and add checks to CI.
- 03
Large repos, rising usage bills
In a large repository, oversized rule files and long agent sessions fill the context window. Output quality drops while usage billing keeps counting. Cursor’s docs advise keeping rules short and scoped.
What we do: We scope rules by path, split the work into smaller tasks, and set spend limits.
What we deliver
What a production pass includes
Four pieces of work. Take one as the pilot, or all four in order.
Codebase audit and repair plan
We read the repository, the git history and the agent’s rules. You get a written list of what blocks release, ranked by risk, with the fix for each.
Tests and CI on every change
We add tests around the paths that matter, plus type checks and a CI pipeline. After that, an agent’s change either passes or is rejected before merge.
Security and permissions review
We review auth, data access and secrets. Then we tighten Cursor itself: MCP servers, auto-run settings, ignore files, and privacy mode for the whole team.
Rules your team can maintain
We write project rules, AGENTS.md and Bugbot review rules that encode your conventions. They live in your repository, so every engineer and every agent reads the same instructions.
How it runs
From a free call to a release you trust
Four steps. You see working software every week.
- 01Call
Free 30-minute call
You show us the repository and where it stalled. We agree one pilot deliverable, its scope and its price before any work starts.
- 02Join
Engineer in your repository
A senior engineer can join your Slack and repository within five working days of the call. All work happens in your accounts.
- 03Build
Fix, test, demo
We repair the blockers in order of risk. You get a weekly demo and a written update, so progress is never a guess.

You receive docs, runbooks and training. Your team keeps the rules, the tests and the pipeline, and can continue without us.
Honest fit
When Cursor is the right tool
Cursor is an editor for engineers. It rewards teams that review what it writes.
The platformCursor
Cursor is an AI code editor and coding agent from Anysphere. It reads a codebase, edits across files, runs terminal commands, and reviews pull requests. Agents run in the editor, the command line and on cloud machines.
Where it is strong
- Agents edit many files and run commands in a real codebase
- Rules and AGENTS.md carry project conventions into each request
- One setup across editor, CLI, cloud agents and PR review
Where it stops
- Models keep no memory between sessions, so rules must carry it
- Usage billing: long agent sessions cost more than the seat
- Auto-run allowlists are best-effort, not a security boundary
Cursor is the right tool when
- You have a real codebase in git and engineers who review changes
- The work is multi-file changes, refactors, tests and migrations
- You want one setup across editor, CLI, cloud agents and PR review
We would say no when
- Nobody on the team can read the code the agent produces
- Your policy forbids sending source code to a cloud model provider
- You need a hosted no-code builder, not a code editor
A good Cursor consultant tells you when the tool is wrong for the job. We do that on the call.
Two ways to work
A scoped fix, or an engineer on your team
Both start with the same free call and a paid pilot.
One agreed deliverable
We take a defined piece of work, such as unblocking your release, and deliver it. Scope and price are agreed on the call.
- One deliverable, agreed before work starts
- Weekly demo and written update
- Code in your repository and accounts
- Docs, runbooks and training at handover
A senior engineer on your team
An engineer who works in Cursor daily joins your Slack and your repository, and works to your priorities for as long as the work needs.
- Joins within five working days of the call
- Works in English, in any timezone
- No juniors learning on your project
- NDA signed on request
FAQ
Questions buyers ask first
Plain answers, each complete on its own.
What does a Cursor agency do?
A Cursor agency builds and repairs software with Cursor, the AI code editor from Anysphere. Engineers direct the agent, review each change, and set up rules, tests and permissions. You get working software in your own repository, not a tool subscription.
Can you fix an app built in Cursor without engineers?
Yes. We start by reading the code and the git history, then list what blocks release. Typical work is adding tests, fixing security findings, removing duplicate code and setting up deployment. The pilot deliverable is agreed on the free call.
Why does Cursor keep breaking code that already worked?
Models keep no memory between sessions, so the agent guesses your conventions unless rules state them. Long sessions also lose earlier context. Scoped rules, smaller tasks and tests on every change stop most regressions before they merge.
Is code written with Cursor safe for production?
It can be, with review. Independent testing shows AI-written code often includes known flaws when security is not requested. We review auth, data access and secrets, fix the findings, and add automated checks so new changes are tested before release.
Who owns the code and the Cursor setup?
You do. The code, IP, docs, rules and pipelines live in your repository and accounts from day one. We sign an NDA on request. Cursor’s terms also assign its rights in generated suggestions to the user.
Should we hire Cursor developers or use an agency?
Hire when you need permanent headcount and have time to recruit. Use an agency when the release is blocked now. Our engineer can join your Slack and repository within five working days of the free call.
How much does it cost?
There is no price list. Scope and price are agreed on the free 30-minute call, before any work starts. Work begins with a paid pilot that has one agreed deliverable, so you can judge the result before committing further.

We worked with Seif on the React Native app for our vehicle-appraisal platform. What stood out most was how much ownership he takes: he thinks a feature through, raises edge cases before they turn into bugs, and delivers something that actually works. And then there is one more thing why I wanted to work with Seif after our very first call: Exceptional clear and consistent communication. It is a pleasure to work with him and his team!
