Workflow tool can repair arguments sent as a JSON string

Workflows

Workflow arguments sent as a JSON string are now parsed instead of failing.

Feature flag
tengu_jade_compass Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.229: off

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.229. It isn't a statement about your account. What a flag value here can and cannot tell you

What

When the Workflow tool receives its args as a JSON-encoded string starting with { or [, it now parses it back into a real object or array rather than failing. The repair is controlled by the tengu_jade_compass flag, which falls back to on, so absent a server value the repair applies. With the flag off the same case is only recorded, and the original malformed input is passed through unchanged.

Details
  • The detected shape is classified as args_json_string_to_object or args_json_string_to_array, each with a _named variant.
  • When the flag is off, a _detect_only suffix is added to that classification.
Evidence

args_json_string_to_object

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
