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

With no annotations, the description carries the full burden, and it does add two meaningful facts: the operation is a deactivation (soft, presumably) rather than a destructive delete, and it requires an explicit yes/no confirmation. It stops short of saying whether deactivation is reversible, what happens to in-flight transfers or balances, or how the caller's permissions affect success.

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 opening sentence 'Deactivates the Bridge' is repeated verbatim in the second block, so the description wastes its most prominent position on duplication. The JSDoc parameter block is compact and useful, but the copy-paste artifact suggests the text was assembled carelessly.

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 four-parameter, all-required mutation with no annotations and no output schema, the description covers auth provenance, the confirmation gate, and the deactivation semantics, which is enough to invoke it. It still omits reversibility, side effects on the bridge's assets, and any hint of the return payload beyond '@return: a json object'.

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, and it does: all four parameters are documented with provenance — api_key is the application key, token and wallet_fk come from /access/login, and external_account_id is found on /bridge/list. That is genuinely actionable, though no format or validation details are given.

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 specific verb+resource ('Deactivates the Bridge') and importantly corrects the misleading tool name 'delete' by clarifying the operation is a deactivation rather than a hard delete. It does not, however, distinguish itself from siblings such as netfluid__bridge_rename or netfluid__bridge_list, which an agent must infer from names alone.

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 only usage instruction is 'Confirm (yes/no) before executing', which is a procedural step rather than guidance on when to choose this tool over bridge_rename or other bridge operations. No preconditions, no alternatives, no statement of what state the bridge must be in.

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