Update Database Cell

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided; description only states the update action without disclosing side effects, permissions, or limitations (e.g., value type constraints, idempotency). No contradiction noted.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences with no extraneous information. Every part is relevant and front-loaded with key action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity and full schema coverage, the description sufficiently covers the core operation. Could add a brief note about value parameter or linkedDocId to be more complete, but not strictly necessary.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and description adds minimal value beyond the schema (only a restated hint about 'title' column). Baseline 3 is appropriate as schema already explains parameters well.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it updates a single cell on an existing AFFiNE database row, and specifies using 'title' for the row title. This distinguishes it from siblings like update_database_row or add_database_row.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this vs alternative tools like update_database_row. The description implies use for cell updates but does not compare with siblings or provide exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
