Update docs when code changes

Automatically keep documentation in sync with your codebase as your team ships.

Falconer monitors your connected GitHub repositories and, when a pull request merges, identifies which existing docs are affected and proposes updates.

Review automated updates

When a PR merges in a connected GitHub repository, Falconer automatically detects the affected docs and sends the document owner a Slack notification with Accept, Review, or Reject options. See Keep docs in sync with PRs for a full breakdown of the notification flow.

Trigger a manual update

You can also trigger an update manually — before a PR merges, or when you want more control over the scope of the update.

Trigger an update within a doc

Use a prompt like this from any doc:

Our auth flow will change in this PR: [link]. Update the authentication docs to reflect the new token refresh logic and remove any references to the old session handling approach.

Find stale information across docs

Alternatively, ask Falcon to do a broader check before a release across your docs. In the prompt box on the home page, try:

Do a full review of the rate limiting API docs and update anything that's out of date -- I want to make sure everything is in sync before we publish.

Iterate on the update

Once Falcon drafts the update, open the document and type / to open Falcon in the editor to refine it. You can ask the agent to:

Confirm the scope — learn which sections need updating and which should stay unchanged
Ensure accuracy — cross-reference the PR diff against the existing doc
Refresh code samples — update snippets that reflect the new implementation
Update diagrams — regenerate architecture or flow diagrams to match the new behavior
Tailor the tone — adjust the depth and language for the right reader (like internal engineers vs. external API consumers)
Find related docs — surface other docs that may also be affected by the same change

Once you’re satisfied, accept the changes and they’ll be saved directly to the published doc.
