# Example: schema-validated PR review verdict via `claude_args` + `structured_output`.
#
# Instead of having the agent write its verdict to a file, this asks Claude for a
# result that conforms to a JSON Schema and reads it back from the action output.
# The default-installed Claude CLI (2.1.160) supports `--json-schema`; the
# action reads the schema file below and passes it to the CLI inline, so the
# file-path form works out of the box (see README → "Structured output"). If
# you consume this action through a pre-baked runner image
# (path_to_claude_code_executable), that image's CLI must still support the
# `--json-schema` flag.
