[BUG]: todoread tool missing schema causes 400 error with Antigravity API #9131
Description
Description
The todoread tool is defined without a schema (hasSchema=n in debug output), which causes HTTP 400 errors when using Antigravity API (via opencode-antigravity-auth plugin).
Antigravity's API strictly validates tool definitions and rejects requests where any tool has an empty/missing parameters schema.
Error
Request contains an invalid argument.
Status: 400
Tool Debug Missing: 1
Tool Debug Summary: ... decl=todoread,src=functionDeclarations,hasSchema=n ...
Expected Behavior
todoread should have a minimal schema, e.g.:
{
"parameters": {
"type": "object",
"properties": {
"_placeholder": {
"type": "boolean",
"description": "Placeholder. Always pass true."
}
},
"required": ["_placeholder"]
}
}This matches the pattern used by other tools like todowrite.
Environment
- opencode version: 1.1.25
- Plugin: opencode-antigravity-auth@beta
- Platform: macOS ARM64
Workaround
Currently no workaround - cannot use Antigravity API with opencode due to this bug.

This may affect other providers with strict schema validation.

These issues are all related to the
todoreadtool's missing schema and parameter validation, affecting various LLM backends that have strict validation requirements (Antigravity API, SGLang, Gemini 3, etc.).Feel free to ignore if none of these address your specific case.
