Cursor Code Review Across Codex, Windsurf, and 45+ AI Agents
AI coding has gone mainstream, but the tooling stack has split fast. JetBrains found that 90% of developers now use at least one AI tool at work, while 74% already use specialized AI coding tools such as assistants, editors, and agents (JetBrains Research, 2026). The old idea that a team will standardize on one editor and one agent is already breaking.
The more revealing stat comes from The Pragmatic Engineer. In its 2026 survey, 70% of engineers said they use two to four AI tools simultaneously, and 15% said they use five or more (The Pragmatic Engineer, 2026). That matches what I keep seeing in practice. One developer wants Cursor for fast UI iteration. Another prefers Claude Code in the terminal. A third is experimenting with Codex or Windsurf for longer-running tasks.
That fragmentation creates a simple problem: most developer tooling still assumes you will pick one winner. CodeProbe does not. I built it as a portable skill in the skills.sh ecosystem, so the same install command, npx skills add nishilbhave/codeprobe, works across the agent stack instead of tying your review workflow to one vendor or editor.
why the AI tooling market is fragmenting
Key Takeaways
- AI coding is now normal work, not experimentation: 90% of developers use at least one AI tool at work (JetBrains Research, 2026).
- Most engineers are already multi-tool users: 70% use 2-4 AI tools simultaneously (The Pragmatic Engineer, 2026).
- CodeProbe's advantage is portability: one install, one audit format, one read-only review workflow across many agents.
Why Does Agent-Agnostic Code Review Matter More in 2026?
JetBrains reported that GitHub Copilot is still used by 29% of developers at work, while Cursor and Claude Code are each at 18%, Google Antigravity reached 6%, and Codex was already at 3% before its desktop launch (JetBrains Research, 2026). The answer is simple: the market is no longer converging around one coding agent, so review tooling tied to one agent now creates unnecessary lock-in.
What changed? Product churn got real. OpenAI launched the Codex desktop app in February 2026 to let developers manage multiple agents in parallel across projects (OpenAI, 2026). Cursor is reportedly discussing a $2 billion raise at a $50 billion valuation while competing directly with Claude Code and Codex (TechCrunch, 2026). Windsurf itself changed hands when Cognition acquired the product, brand, and business in mid-2026, including $82 million ARR and 350+ enterprise customers (Cognition, 2026).
That is not a stable platform layer. That is an active market race. Why would you hardwire a core quality workflow into one product while the ground is moving underneath it?
Developers are not abandoning the field for one universal tool. They are spreading across a fast-changing set of agents and editors.
The practical implication is easy to miss. If your code review workflow only works inside one agent, your quality system inherits the same switching costs, procurement constraints, and product risk as that agent. If your review workflow is portable, your team can change editors without re-learning how to audit code.
According to Stack Overflow's 2026 survey analysis, usage kept rising while trust fell to 29% (Stack Overflow, 2026). That makes portability more valuable, not less. When trust is low, teams need a stable review layer they can carry across tools rather than re-evaluating every vendor's native review output from scratch.
According to JetBrains' January 2026 AI Pulse survey, developers are already split across specialized AI coding tools rather than consolidating on one default choice. GitHub Copilot led at 29% work usage, while Cursor and Claude Code tied at 18%, proving that the winning workflow is increasingly best-of-breed rather than single-vendor (JetBrains Research, 2026).
how agent skills work conceptually
What Is skills.sh, and Why Does It Make CodeProbe Portable?
The short answer is that skills.sh turns agent behavior into reusable, installable capabilities instead of editor-specific plugins. The official skills directory currently lists 38 dev teams and 451 total skills, which is enough scale to make portability a real distribution layer rather than a niche experiment (officialskills.sh, 2026).
That matters because a skill is not the same thing as an extension. An extension usually binds you to one surface area, one product UI, and one release cycle. A portable skill is closer to an operational recipe: instructions, workflows, and optional scripts that an agent can carry with it across environments.
The root of the idea is boring on purpose. Install once. Reuse everywhere. Update centrally. Remove cleanly. That sounds small, but it changes the shape of AI tooling adoption inside a team. Instead of asking, "Which editor are we standardizing on?" you can ask, "Which workflows do we want every agent to know?"
The same mechanics apply to CodeProbe:
npx skills add nishilbhave/codeprobe
npx skills update
npx skills remove
That install flow is the same on macOS, Linux, and Windows. There is no repo clone, no curl script, and no editor-specific package manager. The point is not novelty. The point is minimizing setup friction so the audit workflow survives even when the surrounding AI stack changes.
Why am I so opinionated about this? Because coding agents are moving toward the same end state: they all want to orchestrate longer-running tasks, use tools, and collaborate through skills or equivalent abstractions. OpenAI's Codex app now explicitly supports skills as a way to extend the agent beyond code generation (OpenAI, 2026). JetBrains is moving in the same direction with open agent infrastructure and LLM-agnostic tooling (JetBrains Research, 2026).
That convergence is why portable skills matter. The editor can change. The workflow should not have to.
The official agent skills directory lists 451 total skills from 38 dev teams, which shows that portable agent capabilities are becoming their own ecosystem rather than an edge feature. When workflows are packaged as skills instead of editor-specific plugins, teams can change agents without discarding the operating knowledge built around them (officialskills.sh, 2026).
why architecture beats bolt-on features in AI products
Which AI Coding Agents Can Run CodeProbe Today?
The official agent skills directory now lists 451 skills from 38 dev teams, which is enough ecosystem maturity to make portable agent support meaningful instead of theoretical (officialskills.sh, 2026). In practice, CodeProbe works across 45+ supported agents through that same skills ecosystem, including Claude Code, Cursor, Codex, Windsurf, Cline, Aider, Continue, and others (CodeProbe README).
This is the key distinction between agent support and feature parity. I am not claiming every host environment looks identical. They do not. The host UI changes. The invocation surface changes a bit. The surrounding ergonomics change. What stays consistent is the install path, the audit logic, and the report output.
That consistency is more valuable than it sounds. If one teammate prefers a terminal-first workflow and another lives in an AI editor, both can still run the same audit and compare the same report structure. You do not end up debating whether a problem is in the code or in the host tool's review style.
The host agent can change. The install flow, audit intent, and report structure stay stable.
If your current agent is on the skills.sh list, the odds are good that CodeProbe can come with you. If your team switches next quarter, the audit workflow still makes the trip.
The point of agent support is not infinite breadth for its own sake. It is workflow continuity. With hundreds of portable skills now listed in the official directory and CodeProbe available across 45+ supported agents, teams can standardize the review process without standardizing the editor choice first (officialskills.sh, 2026).
Is the Quickstart Actually the Same in Cursor, Codex, and Windsurf?
The Pragmatic Engineer found that 55% of engineers now regularly use AI agents, and code review is already among the most common agent use cases (The Pragmatic Engineer, 2026). So yes, the quickstart is intentionally repetitive: install the skill once, then run the same audit command in whichever supported agent you already use.
npx skills add nishilbhave/codeprobe
/codeprobe audit .
You can think of the per-agent quickstart like this:
- In
Cursor, install the skill, then run/codeprobe audit . - In
Codex, install the skill, then run/codeprobe audit . - In
Windsurf, install the skill, then run/codeprobe audit . - In
Claude Code, install the skill, then run/codeprobe audit .
That is not a marketing trick. It is a distribution choice. I wanted the onboarding path to be identical because every extra branch in setup hurts adoption. If the agent changes but the muscle memory stays the same, teams keep using the review workflow instead of deferring it. If review is already becoming a standard agent use case, standardizing the command surface across agents is one of the simplest ways to lower friction.
The default modern workflow is already multi-tool, which is exactly why portable skills beat editor-bound setup.
In The Pragmatic Engineer's 2026 survey, 70% of engineers said they use between two and four AI tools, and another 15% said they use five or more. That makes a portable install path more practical than an editor-specific one, because multi-tool use is already standard behavior rather than an edge case (The Pragmatic Engineer, 2026).
the sub-skill architecture and scoring formula in detail
What Does CodeProbe Actually Do Once It Is Installed?
The Pragmatic Engineer found that 55% of engineers now regularly use AI agents, with code review and code validation among the most common use cases (The Pragmatic Engineer, 2026). CodeProbe turns that behavior into a structured, read-only audit that writes severity-scored findings, copy-pasteable fix prompts, stack-aware analysis, and a timestamped report saved to ./codeprobe-reports/<timestamp>.md (CodeProbe README).
The architecture is straightforward:
securitySOLIDarchitectureerror handlingperformancetestingcode smellspatternsframework
I am intentionally not expanding that into a giant table here because I already did that in the deeper CodeProbe articles. This piece is about portability. Still, you should know the important mechanics.
First, CodeProbe auto-detects the stack. It looks for the file types and project markers that tell it whether it is dealing with Python, TypeScript, React or Next.js, PHP or Laravel, SQL, or a mixed codebase. Then it loads the matching reference guides before running the audit.
Second, the scoring system uses capped penalties. Critical findings subtract 15 points each with a 50-point cap per category. Major findings subtract 6 with a 30-point cap. Minor findings subtract 2 with a 10-point cap. That keeps one noisy category from crushing the overall score while still making genuine risk visible.
Third, it is strictly read-only. It does not edit files. It does not auto-apply changes. It generates fix prompts you can paste into your agent yourself. I built it that way because trust is still fragile. Stack Overflow's AI trust analysis showed trust at just 29% even as usage kept climbing (Stack Overflow, 2026). A review tool should help you decide, not silently mutate your codebase.
When I ran CodeProbe against this blog repo on April 23, 2026, it returned an overall health score of 61/100, with Security at 21/100, Error Handling at 49/100, and Architecture still healthy at 88/100 in a 100-file codebase. That spread is exactly why I prefer per-category scores and capped penalties. A repo can be structurally solid and still have urgent security problems that deserve immediate attention.
The operational details matter too:
- Install:
npx skills add nishilbhave/codeprobe - Manage:
npx skills update,npx skills remove - Reports: saved to
./codeprobe-reports/<timestamp>.md - License: MIT
- Optional runtime: Python 3.8+ for the statistics dashboard
Those details are unglamorous, but they are what make the tool usable across real teams. If your audit output can be shared in a PR, diffed between commits, and read the same way regardless of host agent, the workflow survives contact with reality.
CodeProbe's review model is deliberately read-only: it audits the codebase across nine specialized domains, generates copy-pasteable fix prompts, and saves a timestamped Markdown report to
./codeprobe-reports/<timestamp>.md. That design matches the current trust climate, where developers use AI heavily but still demand human control over production changes (Stack Overflow, 2026).

Why Is One Consistent Audit Output Better Than Native Tool Lock-In?
Because consistency reduces both training cost and switching cost. When 55% of engineers already use AI agents regularly and most use more than one AI tool, the durable advantage is not "our editor has a review feature." It is "our team can run the same quality workflow regardless of which agent is in front of us" (The Pragmatic Engineer, 2026).
There are four practical benefits.
Lock-in avoidance. If one vendor changes pricing, model access, enterprise terms, or product direction, you can move without recreating your review system.
Team flexibility. Different engineers can use the agent that fits their work while still speaking the same audit language. UI-heavy work and backend-heavy work do not need the same host tool.
Comparable reports. A Markdown report written to disk is easier to compare across runs than a vendor-specific sidebar or ephemeral chat output. That matters when you want to track regressions over time.
Simpler onboarding. New teammates do not need a separate mental model for review in every agent. Install the skill. Run the audit. Read the same report format. Done.
This is also where the portability argument stops being abstract. A lot of AI product marketing still assumes the editor is the center of the universe. I think that is backward. The durable layer is the workflow, not the chrome around it.
My bet is that the winning AI development stack will look more like a modular toolchain than a single monolith. Editors, agents, models, and skills will keep swapping faster than teams want to rewrite their operating habits. Portable review workflows are a hedge against that churn.
When 70% of engineers already use two to four AI tools and 55% regularly use agents, the durable advantage is not an editor-specific review tab. It is a portable workflow that keeps reporting, scoring, and review habits stable while the surrounding tool stack keeps changing (The Pragmatic Engineer, 2026).
If you accept that premise, then CodeProbe's portability is not a convenience feature. It is the actual product positioning.

Frequently Asked Questions
Do I need to reinstall CodeProbe for every project?
No. The install is tied to the agent skill environment, not to each repository. That matters because 70% of engineers already use 2-4 AI tools at once, so repeating setup per repo would add friction exactly where multi-tool teams feel it most (The Pragmatic Engineer, 2026).
Does CodeProbe behave differently in different agents?
The host experience changes a bit, but the audit logic stays consistent. That is the important part. JetBrains found developers are already split across specialized coding tools, with no single tool dominating enough to justify a single-host review strategy, Copilot leads at 29%, while Cursor and Claude Code are both at 18% (JetBrains Research, 2026).
What if my agent is not on the list today?
The practical answer is to check the skills ecosystem first, because support coverage is already broad. CodeProbe is built for the skills.sh model, and the official agent skills directory already spans 451 skills from 38 dev teams (officialskills.sh, 2026). Coverage is the rule now, not the exception.
Is this just a wrapper around an agent's native review feature?
No. Native review features are usually host-specific. CodeProbe is a portable, read-only audit workflow with its own scoring, sub-skill model, and report structure. That distinction matters when trust in AI is still only 29% despite heavy usage, because teams need review output they can supervise and compare across tools (Stack Overflow, 2026).
Why not just use an editor-specific extension instead?
You can, if you are comfortable tying review to one product. I am not. Cursor, Codex, and Windsurf are all moving quickly, and product direction changes can be dramatic. In a market where 70% of engineers already use multiple AI tools, portable workflows age better than editor-specific ones (The Pragmatic Engineer, 2026).
Conclusion
The AI coding market is not settling down into one obvious winner. It is splitting into a stack of specialized editors, terminal agents, orchestration layers, and portable skills. JetBrains' January 2026 data and The Pragmatic Engineer's multi-tool survey both point in the same direction: developers already work across several tools, and that behavior is only becoming more normal.
That is why I built CodeProbe as an agent-agnostic skill instead of a single-editor feature. One install. One audit command. One report format. The host can change later.
If that sounds like the right tradeoff for your workflow, install CodeProbe with npx skills add nishilbhave/codeprobe, run /codeprobe audit ., and compare the report across whatever coding agent you are already using.
