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

Annotations already disclose that this is a non-read-only, non-idempotent, open-world mutation with destructiveHint=false. The description adds useful scope ('public Trana nodes') and outcome ('node graph shows them together'), but does not explain permissions, reversibility, or what the 'remove' flag does.

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 purpose is front-loaded in a single sentence with little wasted text. However, the description is visibly truncated ('t-<id>' or...'), making it under-specified rather than appropriately complete.

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 six-parameter mutation with an enum, no output schema, and 0% schema description coverage, the description is far too incomplete. It omits the meaning of most parameters and the detach/remove behavior, leaving the agent without enough detail to call the tool 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 0%, so the description must carry parameter meaning. It only partially explains that 'from' and 'to' use a 't-<id>' format and then truncates with 'or...', leaving 'key', 'why', 'kind' (an enum with seven values), and 'remove' unexplained.

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 clearly states a specific verb and resource: 'Link two public Trana nodes' and explains the visible effect on the node graph. It does not differentiate this tool from related siblings such as thread_link or space_trana_link, and the trailing 'or...' leaves the thought incomplete.

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?

It implies use when linking nodes, but gives no explicit when-to-use guidance and does not compare to alternatives like node_create, node_edit, thread_link, or space_trana_link. The 'public Trana nodes' phrase hints at scope but does not tell the agent when this tool is the right choice.

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