saved_posts_status

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. The word 'Return' indicates a read-only operation, which is helpful, but the description does not mention potential side effects, whether it triggers a cache refresh, permissions needed, or any other behavioral nuances. It is minimally transparent but not rich.

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, front-loaded sentence with no filler or redundancy. Every phrase ('cache statistics,' 'database path,' 'last sync run status') adds concrete value, and the structure is immediately scannable.

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?

The tool is simple (zero parameters) and has an output schema, so the description need not enumerate return fields. It names the three key categories of information, which is sufficient for an agent to select and invoke it appropriately in most contexts. The sibling tool list does not reveal any missing prerequisites or caveats.

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 tool has zero parameters, so the baseline is 4 per the rubric. The description correctly focuses on outputs rather than inputs, and there is no parameter ambiguity to resolve. It adds no parameter info because none is needed.

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 tool's verb ('Return') and resource ('cache statistics, database path, and last sync run status'), making it distinct from the sibling tools like save_post or search_saved_posts. It does not explicitly name alternatives, but the specificity is sufficient to understand its role as a status/diagnostic tool.

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 provides no guidance on when to use this tool versus its siblings, such as when to use sync_saved_posts versus checking sync status here. The intended use is only implied by the output list, but there are no explicit conditions, exclusions, or alternative recommendations.

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