chunk_details

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

No annotations provided, but description states it returns chunk content as string, indicating a read-only operation. Usage patterns imply safe behavior. Could add error cases but sufficient for a simple tool.

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?

Three concise sentences: purpose, return type, usage patterns. No wasted words, front-loaded with key information.

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?

For a simple tool with one parameter and no output schema, the description is largely complete. Mentions common patterns to aid understanding. Could add a note on where chunk_id comes from.

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 has one parameter 'chunk_id' with 0% description coverage. Description does not explain what chunk_id is or how to get it, so the agent must infer from context.

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 'Get full content of a specific chunk' with a verb and resource. It distinguishes from sibling tools like find_matching_chunks_in_file by focusing on retrieval rather than search.

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?

Explicitly lists common patterns: final step after find_matching_chunks_in_file, examining implementations. This gives clear guidance on when to use and contrasts with alternatives.

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