Get cached Cascade asset nodelet

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

Annotations already declare readOnlyHint, destructiveHint, and idempotentHint. The description adds value by clarifying that this is a convenience view not audit-complete, that it never reads Cascade directly (thus cached), and describes oversized responses returning bounded _cache metadata. No contradiction with annotations.

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?

The description is five sentences, front-loaded with the main purpose. Each sentence adds meaningful information without redundancy. It is appropriately sized for the tool's complexity.

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 read tool with no output schema and 4 parameters, the description explains response format (JSON text), authoritative structuredContent, and oversized response behavior. It also references cascade_read for context. While additional details on response structure could help, it is largely complete given the annotations.

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 100%, so baseline is 3. The description adds context about JSON Pointer, bounded subtree, and authoritative structuredContent, but does not provide parameter-specific details beyond the schema. It adds some value but not significant.

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 the verb 'fetch' and the resource 'exact structuredData nodelet or bounded subtree at a JSON Pointer', and situates the tool after cascade_read. It distinguishes from siblings by noting it is a convenience view over structuredDataNodes, not an audit-complete view, and that it never reads Cascade directly.

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?

The description explicitly says 'Use after cascade_read', providing clear context. However, it does not explicitly state when not to use this tool or list alternative tools for different scenarios, though it implies that for full asset reads one should use cascade_read.

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