origin_get_cell_value

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

No annotations are present. The description only states 'Read', implying a safe operation, but lacks details on error handling, return value type, or idempotence. It does not contradict annotations, but minimal behavioral context is added.

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?

A single sentence that front-loads the core purpose. Every word adds value, with no redundancy or fluff.

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 4 parameters and an output schema, the description omits details like return value type, behavior for empty cells, or the effect of optional parameters. It is insufficient for an agent to fully understand the tool's capabilities.

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 description coverage is 0% and the description adds little beyond the schema. It mentions zero-based indexing but does not explain the column parameter's acceptance of string column header or integer index, nor the optional book_name and sheet_name parameters.

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 'Read one worksheet cell value' with specific verb and resource. It mentions zero-based row and column name/index, distinguishing it from 'origin_read_worksheet' (reads entire sheet) and 'origin_set_cell_value' (writes).

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 guidance on when to use this tool versus alternatives like 'origin_read_worksheet'. No exclusions or context provided for when a different tool is more appropriate.

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