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

No annotations are provided, so the description carries the full burden. It mentions 'Update' which implies mutation, but fails to disclose critical behavioral traits such as required permissions, whether changes are reversible, error handling, or rate limits. This leaves significant gaps in understanding the tool's operational impact.

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 is front-loaded with the core action. There's no wasted text, though it could benefit from slightly more detail given the tool's complexity. It's appropriately sized but under-specified rather than concise.

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 mutation nature, 4 parameters with 0% schema coverage, no annotations, and multiple sibling alternatives, the description is incomplete. While an output schema exists, the description lacks context on usage, parameters, and behavioral transparency needed for safe and effective tool invocation.

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 but adds no parameter information. It doesn't explain what 'entity_id' refers to, what 'top-level state' includes, or the semantics of 'name', 'description', and 'status' parameters. This leaves all 4 parameters poorly understood beyond their basic types.

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 states the tool 'Update[s] an existing entity's top-level state' which provides a clear verb ('Update') and resource ('entity'), but it's vague about what 'top-level state' specifically means. It doesn't distinguish this tool from sibling tools like 'upsert_entity' or 'set_tags', leaving ambiguity about when to choose one over another.

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 guidance is provided on when to use this tool versus alternatives. With sibling tools like 'upsert_entity', 'set_tags', and 'merge_entities' available, the description offers no context about prerequisites, appropriate scenarios, or exclusions, leaving the agent to guess based on tool names alone.

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