get_posts

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool retrieves a list with filtering and pagination but doesn't cover critical aspects like whether it's read-only, rate limits, authentication needs, error handling, or what the return format looks like (e.g., JSON structure). This leaves significant gaps for an agent to understand the tool's behavior.

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 a single, efficient sentence that front-loads the core purpose ('Get a list of posts') and adds essential qualifiers ('with optional filtering and pagination') without any wasted words. It's 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?

Given the tool's moderate complexity (6 parameters, no output schema, no annotations), the description is adequate but incomplete. It covers the basic purpose and hints at parameter usage but lacks details on behavioral traits, return values, and sibling differentiation, making it minimally viable but with clear gaps.

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?

The description mentions 'optional filtering and pagination,' which aligns with parameters like 'id', 'title', 'skip', and 'limit' in the schema. However, with 100% schema description coverage, the schema already fully documents all 6 parameters, so the description adds minimal value beyond reinforcing the general purpose of filtering and pagination.

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 ('Get') and resource ('list of posts'), making the purpose unambiguous. However, it doesn't differentiate from sibling tools like 'get_talks' or 'get_videos' beyond mentioning posts specifically, so it lacks explicit sibling distinction.

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 mentions 'optional filtering and pagination' but provides no guidance on when to use this tool versus alternatives like 'get_talks' or 'get_videos', nor does it specify any prerequisites or exclusions for usage.

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