get_world_state

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

No annotations provided, so description carries full burden. It discloses the snapshot is fresh, capped, and prefers high-importance entities when over capacity. However, it does not mention side effects (likely read-only), performance, or authorization needs. Adds some context beyond schema but not exhaustive.

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?

Two sentences front-loaded with key purpose and constraints. No extraneous words; every sentence adds value.

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 no output schema, description covers return fields and cap behavior. Slight ambiguity remains on entitiesByName structure and timestamp format, but overall sufficient for an agent to understand the tool's output and constraints.

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?

No parameters exist; schema coverage is 100% trivially. Baseline is 4. Description adds value by describing the output structure (entitiesByName, takenAt, size) and constraints, compensating for lack of output schema.

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?

Description states verb 'capture', resource 'snapshot of the live graph', and contents 'entitiesByName + takenAt timestamp + size'. It clearly distinguishes from siblings by describing a fresh snapshot with size cap and importance-based selection, unlike other graph reading tools.

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?

No explicit when-to-use or alternatives. The description implies for capturing current graph state, but lacks comparison to similar sibling tools like read_graph, inspect_entity, or get_graph_stats.

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