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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, which cover the safety profile. The description adds little beyond that—'privacy-filtered project metadata' is vague and does not explain what the update actually does, what is overwritten, or any side effects. It does not contradict annotations, but it also does not enrich them.

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 extremely short, but this is under-specification rather than conciseness. It omits critical information about parameters, usage, and behavior. The single sentence is not front-loaded with actionable details; it merely states a generic action.

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 a 7-parameter schema with nested objects and no output schema, the description is grossly inadequate. It fails to explain the purpose of each parameter, the expected behavior of the update, or any constraints. An agent cannot reliably invoke this tool correctly based on the provided description alone.

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 by explaining the meaning and relationships of the parameters. It does not mention any parameter, such as sourceId, targetId, projectId, or idempotencyKey. The required parameters are completely undocumented in prose, leaving the agent to guess their semantics.

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 a verb ('update') and a resource ('hosted link context project node'), but the resource is jargon and ambiguous. It does not differentiate from the sibling tool 'link_context_nodes', which could be confused with this operation. The qualifier 'privacy-filtered project metadata' hints at a filtering mechanism but remains unclear.

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 given on when to use this tool versus alternatives such as 'link_context_nodes' or other update tools. There is no mention of prerequisites, typical scenarios, or exclusions. The agent is left to infer the appropriate context from the name alone.

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