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 disclose one genuinely useful trait: the effect is scoped to managed stops and leaves book orders intact, which bounds the blast radius of the mutation. It says nothing about permissions/ownership requirements, whether the cancellation is reversible by re-issuing set_hyperliquid_managed_exit, what happens if no managed exit exists, or what the response contains.

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?

Two short sentences, zero filler, and the operative scope constraint is front-loaded before the caveat. Nothing could be removed without losing information.

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?

The description explains the effect and its boundary well, which is the hardest part of this mutation tool, but with no annotations, no output schema, and two fully undocumented required parameters, key details for actually invoking it correctly (symbol format, walletId semantics, failure modes) are missing.

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 both required parameters (walletId, symbol) are undocumented in the schema and the description makes no reference to either. An agent must guess that symbol is a Hyperliquid market symbol and that walletId identifies the wallet holding the position, and whether the symbol must match the position's exact notation.

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 uses a clear verb ('Turn off') plus a precise resource ('the trailing or time stop FortFi manages on a position'), so the agent knows exactly what is being cancelled. The second sentence implicitly separates it from cancel_hyperliquid_orders by stating that stops already on the book are untouched, though it never names that sibling.

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?

Usage context is implied: this is for removing FortFi-managed trailing/time stops rather than exchange-resident orders, which the 'stops already on the book stay where they are' clause conveys. There is no explicit when-to-use guidance, no mention of the counterpart set_hyperliquid_managed_exit or list_hyperliquid_managed_exits for discovering existing managed exits, and no stated prerequisites.

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