Asymptote hooks into Factory’s Droid agent to automatically evaluate every file edit against your security policies as Droid works.

​
Prerequisites

  • Asymptote CLI installed (asym command)
  • A Factory account with Droid configured
  • Logged in to your Asymptote account (asym login)

​
Setup

1

Install the Asymptote CLI

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

Install hooks for Factory

Run the install command. By default, hooks are installed at the user level (~/.factory/settings.json) and apply to all projects:
asym factory install
To install only for the current project:
asym factory install --project
3

Run Droid

Start a Factory Droid session as normal. Asymptote will evaluate every file edit against your security policies automatically—no changes to your workflow are required.

​
How it works

Once installed, Asymptote registers four hooks in Factory’s settings.json:
HookPurpose
SessionStartInitializes the session and performs cleanup
PostToolUseSubmits diffs for async security evaluation
StopPolls results and re-prompts Droid on violations
SessionEndFinal cleanup
Droid will automatically remediate any policy violations before finishing its response.

​
Uninstalling

To remove the Asymptote hooks from Factory: 
asym factory uninstall
To remove project-level hooks only: 
asym factory uninstall --project
