Optional settings from the registry entry, left out of the block above: CLAUDE_CLI_PATH (Path to the claude CLI binary. Defaults to 'claude' on PATH), CLAUDE_DEFAULT_MODEL (Shared default model for all tools. Overridden by per-tool CLAUDE_<TOOL>_MODEL vars (QUERY, SEARCH, STRUCTURED)), CLAUDE_QUERY_MODEL (Override model for the query tool), CLAUDE_STRUCTURED_MODEL (Override model for the structured tool), CLAUDE_SEARCH_MODEL (Override model for the search tool), CLAUDE_FALLBACK_MODEL (Model to use when the primary model hits a quota error. Set to 'none' to disable fallback), CLAUDE_MAX_CONCURRENT (Maximum concurrent Claude CLI subprocesses (default 3)), CLAUDE_BRIDGE_USE_API_KEY (Set to '1' to forward ANTHROPIC_API_KEY to the CLI. Default is subscription-first: the CLI uses existing Max/Pro session and API key is NOT forwarded. Opt in only if you want API billing), CLAUDE_MAX_BUDGET_USD (Maximum USD spend per call (pass-through to --max-budget-usd). Only applies when using API key auth), CLAUDE_QUERY_TOOLS (Built-in tools the query subprocess may use. Comma or space separated list, 'default' for the CLI's full built-in set, or empty for no tools. The default withholds Bash, Write and Edit; widening it grants real capability in the caller-supplied working directory), CLAUDE_STRUCTURED_TOOLS (Built-in tools the structured subprocess may use. Same format and caveats as CLAUDE_QUERY_TOOLS), CLAUDE_SEARCH_TOOLS (Built-in tools the search subprocess may use. Same format and caveats as CLAUDE_QUERY_TOOLS), CLAUDE_QUERY_EFFORT (Reasoning effort for the query tool (low|medium|high|max)), CLAUDE_SEARCH_EFFORT (Reasoning effort for the search tool (low|medium|high|max)).
