C2.8/5.0
Behavior2/5

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

With no annotations, the description carries the full burden for behavioral disclosure. It only says 'generic alias' and 'instructions', implying a read-like, non-destructive operation, but it does not describe what the tool actually returns, whether it forwards parameters, or any side effects. This is a significant gap given zero annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, compact sentence that immediately names the tool as an alias and states its use case. Every word earns its place; there is no fluff or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the overwhelming parameter count (43), no output schema, and a very large sibling set, a one-sentence alias description is grossly inadequate. The agent is left without any guidance on invocation, return shape, parameter selection, or how this alias relates to the nearly identical start_here tool. The description fails to compensate for the structural complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description provides no parameter information whatsoever. With 43 parameters and only 33% schema description coverage, the tool is highly complex and the description adds nothing to help an agent understand which parameters are relevant or how they map to the underlying start_here tool. The schema itself is largely opaque.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states this is a 'generic alias for start_here', giving a specific resource and identifying its role as an entry point for instructions. It distinguishes itself as an alias, though it does not elaborate on the content or scope of the instructions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides a useful context cue: 'useful for agents and probes looking for instructions before using paid tools'. However, it does not explicitly compare against sibling tools like start_here, wisely_start_here, or wisely_agent_instructions, nor does it state when not to use this alias.

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