get_setup_guide

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

No annotations are provided, so the description carries the full behavioral burden and discloses almost nothing: not whether the guide is static content or generated, not its size or format, not whether the call has side effects. The only signal is an implicit read, which the agent must infer.

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, so it is concise. But brevity here comes at the cost of meaning – the phrasing is cryptic rather than tight, and "the same guide" front-loads an unresolved reference.

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 annotations, no output schema, and no parameters, the description is the only source of information about this tool, and it does not say what the guide contains or what the agent gets back. For a zero-arg lookup tool this leaves the caller unable to predict results.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The remaining ambiguity is about the return value, not inputs.

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?

"Read the same guide" names an action and a resource only in the vaguest sense; "the same guide" is a dangling reference that presumes context the agent does not have. Nothing distinguishes this from sibling setup tools like setup_status or setup_begin.

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 call this versus setup_status or setup_begin. The phrase "from a checkout or an installed distribution" hints at environments but never tells the agent which situation should trigger the call or whether ordering matters.

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