Asymptote hooks into Cursor’s agent to automatically evaluate every file edit against your security policies before code is written to disk.

​
Prerequisites

  • Asymptote CLI installed (asym command)
  • A Cursor editor with agent mode enabled
  • Logged in to your Asymptote account (asym login)

​
Setup

1

Install the Asymptote CLI

Install the CLI via Homebrew:
brew install asymptote-labs/tap/asymptote-cli
Then log in:
asym login
2

Install hooks for Cursor

Run the install command from any directory. By default, hooks are installed at the user level and apply to all projects:
asym cursor install
To install only for the current project, use the --project flag:
asym cursor install --project
3

Restart Cursor

Restart Cursor to activate the hooks. Asymptote will now evaluate every file edit made by Cursor’s AI agent against your security policies automatically.

​
How it works

Once installed, Asymptote registers hooks in Cursor’s hooks.json. For every file edit the AI agent makes, Asymptote:
  1. Captures the diff
  2. Evaluates it against your security policies
  3. Re-prompts the agent to remediate any violations before writing to disk
No changes to your Cursor workflow are required.

​
Uninstalling

To remove the Asymptote hooks from Cursor: 
asym cursor uninstall
To remove project-level hooks only: 
asym cursor uninstall --project
Restart Cursor after uninstalling to deactivate the hooks.
