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

Annotations already declare the safety profile (readOnlyHint=false, idempotentHint=true, destructiveHint=false), lowering the bar. The description contributes the useful detail that only 'privacy-filtered project metadata' is sent, but it does not say what is mutated, whether prior links are replaced, or what auth/permissions are needed.

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?

A single compact sentence with the action front-loaded and no filler. It is efficient, though the compressed jargon makes it less immediately parseable than it could be.

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 a 7-parameter mutation tool with a nested object and no output schema, the description is thin: it never explains what the operation actually changes, what the source/target/project IDs refer to, or what a successful call yields. Annotations cover safety but not the semantic gaps an agent needs to call this confidently.

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 71%, with the required projectId/sourceId/targetId and the nested details object well documented (including the 'no local paths or repo URLs' and 'not arbitrary command arguments' constraints). The description adds nothing about parameters, so it neither compensates nor detracts; baseline 3 applies.

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 gives a verb+resource ("Update hosted link context project node") and adds a scope qualifier ("privacy-filtered project metadata"), so the basic action is recoverable. However, "link context project node" is opaque jargon and the description does not distinguish this tool from the close sibling link_context_nodes or clarify what a 'node' here is versus a context node.

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?

There is no when-to-use guidance, no prerequisites, and no named alternative (e.g. link_context_nodes for initial linking vs. this for updates). The retry/idempotency contract lives in the schema's idempotencyKey field, not in the description, so an agent gets no routing help from the prose.

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