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

Annotations already establish that this is a read-only, closed-world operation, so the safety profile is covered. The description adds the useful behavioral point that the tool produces a retry-safety decision rather than just a label, but it never says what classifications are returned or that retry safety depends on idempotency (the 'method' input), which is the most consequential behavior here.

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 front-loaded sentence with no filler, so it reads cleanly and states the outcome first. The brevity shades into under-specification rather than tightness, since key semantics (method, output shape) are dropped rather than compressed.

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?

With no output schema and 0% schema description coverage across two parameters, the description is the only source of detail, and it omits both the return categories and the role of 'method'. For a decision tool whose whole value is the classification it emits, that leaves an agent guessing at the result format.

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 carry parameter meaning and it largely does not. It refers to 'response status' but never explains the expected format (raw HTTP integer code), and the 'method' parameter is entirely unmentioned even though HTTP method/idempotency is central to whether a retry is safe.

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 and resource ('Classify response status') and adds the decision it supports ('whether a retry might be safe'), which is enough to tell it apart from pure utility siblings like privi_backoff_window or privi_json_canonical. It does not explicitly contrast itself with adjacent retry/circuit siblings, so it stops short of a 5.

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 is only implied: an agent can infer it should call this when holding an HTTP status and needing a retry-safety judgement. There is no explicit when-not guidance, no statement about prerequisites, and no named alternative for related questions such as backoff timing or circuit state.

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