describe_video把本地视频交给 Gemini 直传识别，返回按时间轴分段的详细内容描述（画面 + 音轨）。
describe_video_url从【网络直链】下载视频再交给 Gemini 识别，返回按时间轴分段的中文描述。
estimate_cost估算把某个本地视频交给 Gemini 识别大概要花多少输入 token，让你发大视频前心里有数。
view_media把一张【图片】、或【视频的某一帧】作为图片内容直接返回，让调用方模型亲眼看到画面。
get_upload_url获取"把文件推到本服务器"的上传地址——用于把 claude.ai 聊天里上传/沙盒里生成的文件搬到服务器再识别。

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
5/5 tools missing one or more hints — describe_video (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); describe_video_url (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); estimate_cost (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +2 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — describe_video_url deletes at line 617 (temp_path.unlink(missing_ok=True))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool inputs are validated
4/5 tool handlers declare input schemas (80%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
4/5 tool handlers wrap calls in try/catch (80%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
