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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds the useful constraint that searching is confined to an allowed path, but says nothing about result caps, ordering, or what happens when maxResults truncates matches.

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, front-loaded with the usage condition and followed by the device hint. No padding, though the second sentence spends space on something the schema already says.

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?

Six parameters, no output schema, and only a third of the schema documented. For a search tool the description should at least clarify pattern matching semantics and default result limits; instead an agent must guess how 'pattern' is interpreted and whether results are capped at maxResults=100 by default.

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 only 33%: only path and device are documented in the schema, while pattern, maxDepth, ignoreCase and maxResults are bare. The description's only parameter remark ('Select the target with the optional device argument') merely restates the schema, and it never explains whether pattern is a glob, regex, or substring match — the single most important semantic here.

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 ('search file and directory names') plus a scope ('below an allowed path'), and the 'names' qualifier implicitly separates it from nymrel_remote_search_content. It stops short of naming that sibling explicitly, so the separation requires inference.

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?

'Use this when the user explicitly wants...' gives a trigger condition, which is more than nothing, but there are no exclusions and no named alternative — notably it never says to use nymrel_remote_search_content instead when the user wants file contents rather than names.

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