Note

Low Risk
Mostly generated type/doc updates plus a version bump; the only functional surface-area change is additive optional fields, which is unlikely to break consumers.

Overview
Release 0.34.0 updates generated SDK types and docs.

Adds an optional machine-readable error_code to managed auth flow models/responses (alongside error_message). Updates browser/brower-pool viewport documentation to allow arbitrary dimensions (with a list of known-good presets and refresh-rate behavior).

Extends AppAction with optional input_schema/output_schema JSON Schema fields, tweaks the docs formatting script to run across all api.md files, and includes a small Python 3.14 typing lint suppression; version and OpenAPI spec metadata are bumped.

[cursor]

Docs formatter now depends on Bash

Medium Severity

The format:docs script now runs through bash -c, which introduces a hard Bash dependency. Environments without Bash (notably common Windows setups) can no longer run format:docs, so local formatting workflows fail even though the previous python-only command worked cross-platform.

 

[cursor]

Docs formatting scans unintended directories

Medium Severity

format:docs now expands $(find . -type f -name api.md) without excluding directories like .venv or build artifacts. This can pass third-party or generated api.md files to ruffen-docs, causing unexpected edits or failures outside the project’s intended docs set.
