Get PubNub SDK Migration Guide

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

No annotations are provided, so the description carries the burden. It states the tool returns 'migration guide content for the specified language and target version', which is a basic behavioral trait. It does not disclose any additional traits like idempotency, rate limits, or potential errors. The clarity is adequate but lacks depth for a fully transparent definition.

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 well-structured with clear sections and bullet points, front-loading the core purpose. Minor verbosity from markdown formatting (bold, line breaks) but overall efficient. Every sentence earns its place, though the 'When to use' and 'Do NOT use for' sections could be slightly condensed.

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 low complexity (two enum parameters, read-only behavior), the description sufficiently covers purpose, usage guidelines, and sibling differentiation. It lacks an output schema but explicitly states what is returned ('migration guide content'). This is adequate for the tool's simplicity.

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%, so the description must compensate for missing parameter explanations. The description merely references 'specified language and target version' without adding details beyond the enum names (e.g., valid versions 7,8,10,13). It does not explain what each version maps to or any additional constraints. The enum values are self-explanatory, but the description adds minimal value.

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 uses the specific verb 'Retrieve' and clearly identifies the resource as 'SDK migration guides for upgrading between PubNub SDK versions'. It explicitly distinguishes from sibling tools like 'get_sdk_documentation' and 'get_chat_sdk_documentation' by naming them in the 'Do NOT use for' section.

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 includes explicit 'When to use' and 'Do NOT use for' sections, listing concrete scenarios (e.g., upgrading major versions, need step-by-step instructions) and specific sibling tool alternatives (e.g., 'get_sdk_documentation' for general docs). This provides clear guidance on when to invoke this tool vs. others.

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