get_alt_text

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

With no annotations, the description explains the 0-based indexing across wp:docPr elements and the return values, but does not mention error handling (e.g., out-of-bounds index) or confirm it is read-only. Adequate but not comprehensive.

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?

Description is very concise with a one-line summary followed by an Args and Returns block. No superfluous content; every sentence adds value.

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 (one parameter, output schema exists), the description covers the essential behavior. Minor lack: no mention of what happens if the image index is invalid, but overall complete enough for basic use.

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 0%, but the description fully explains the parameter 'image_index' (0-based index across wp:docPr elements) and includes the return format, adding significant meaning beyond the schema alone.

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 gets alt text and title for an image by 0-based index, which is a specific verb-resource pair. Among siblings, there are set_alt_text and set_image_alt_text, so this retrieval tool is well-differentiated.

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 vs alternatives (e.g., set_alt_text, get_images). No exclusions or contextual usage hints beyond the basic retrieval purpose.

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