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

With no annotations, the description must carry the behavioral burden; it does disclose the return shape (hop-by-hop IP, hostname, latency), which is genuinely useful. However it says nothing about runtime characteristics (traces to 30 hops can be slow), timeout behavior, firewall/ICMP blocking, or permission requirements — meaningful gaps for a network probe.

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 sentences, zero waste, with the action and scope front-loaded and the return format immediately after. Nothing redundant or padded.

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?

No output schema exists, and the description compensates by summarizing the returned fields, while the two parameters are fully covered by the schema. It falls short only on operational caveats (expected duration, failure modes) that an agent would want before invoking a potentially slow probe.

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 100%, so both `target` and `max_hops` are already documented with types and a default. The description adds no semantics beyond the schema (e.g., no guidance on when to lower max_hops or what target formats are accepted beyond the schema's own text). Baseline 3 applies.

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 names a specific verb ("Trace") and resource ("network path from the server to a target host"), and its hop-by-hop scope clearly distinguishes it from siblings like ping_host (reachability) or resolve_dns (name resolution). An agent can pick this over those siblings without opening the schema.

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?

There is no statement of when to use this versus ping_host, check_service_access, or resolve_dns, and no exclusions or prerequisites. Usage is only inferable from the verb itself.

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