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

The description goes beyond the sparse annotations by revealing that content is ephemeral and that claiming grants exclusive spatial access, which is important for collision-sensitive coordination. It doesn't spell out TTL or claim-expiry mechanics, but the word 'ephemeral' signals lifetime and 'exclusive' signals blocking semantics without contradicting any annotation.

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 definition is a single focused sentence with no filler. It is efficient and front-loads the core purpose, though it could have used an explicit verb and a brief note about the four action modes.

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?

For an 8-parameter tool with no output schema, the description does not explain how the post/read/claim/release actions map to parameters or what a read result looks like. The schema covers individual parameters, but the description alone is not enough to correctly choose between this and the many sibling spatial tools.

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 100%, so the schema already documents all eight parameters including the action enum, payload coordinates, TTL, and duration. The description only frames semantics conceptually and does not add operational details such as which parameters apply to posting versus claiming.

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 identifies a shared spatial blackboard and names its two core purposes: publishing ephemeral intentions/waypoints and claiming exclusive spatial access. It is not merely a title restatement Durch, but it uses a noun phrase rather than an explicit operation and does not differentiate itself from sibling spatial tools like get_spatial_map or manage_spatial_spec.

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 phrase 'for publishing... and claiming... to prevent collisions' implies when an agent would use this tool, but there are no explicit use conditions, exclusions, or named alternatives. With 14 sibling tools, an agent would still need to infer how this differs from get_spatial_map or wait_for_spatial_state.

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