Cloud Code Assist API requires strict JSON Schema draft 2020-12 compliance
and rejects keywords like patternProperties, additionalProperties, $schema,
$id, $ref, $defs, and definitions.
This extends cleanSchemaForGemini to:
- Remove all unsupported keywords from tool schemas
- Add oneOf literal flattening (matching existing anyOf behavior)
- Add test to verify no unsupported keywords remain in tool schemas
Anthropic blocks specific lowercase tool names (bash, read, write, edit)
when using OAuth tokens. This fix:
1. Renames blocked tools to capitalized versions (Bash, Read, Write, Edit)
in pi-tools.ts via renameBlockedToolsForOAuth()
2. Passes all tools as customTools in splitSdkTools() to bypass
pi-coding-agent's built-in tool filtering, which expects lowercase names
The capitalized names work with both OAuth tokens and regular API keys.
