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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only the password-precondition context; it says nothing about how the original file is handled or the role of the overwrite flag, so credit is limited.

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 short sentence with no filler, and the operative verb is front-loaded. Nothing could be trimmed without losing meaning.

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?

An output schema exists, so return-value explanation is unnecessary, and annotations carry the safety profile. However, for a four-parameter write tool with zero schema descriptions, the definition omits output-file semantics and overwrite behavior, leaving real gaps for correct invocation.

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% across four parameters, so the description bears the full burden and fails it. It hints at the password parameter but says nothing about path, output, or overwrite, leaving the agent to infer input location, destination, and clobber behavior from bare names.

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?

States a specific verb and resource — 'Remove the password' from a PDF — which is immediately distinguishable from siblings like protect, redact, or compress. The qualifier 'you can open' adds useful scope, but it never names the counterpart tool (protect) the way a 5 would.

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 phrase 'a PDF you can open' functions as an implied precondition: you must already know the password, so this is not a cracking tool. That is real but indirect guidance; there is no explicit when-to-use versus protect, and no mention of what happens when the password is wrong.

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