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

With no annotations, the description carries the full behavioral burden. It discloses that the result includes a consent question, rule 0, essentials, and recent memory, but says nothing about read-only vs. side effects, permissions, idempotency, or interaction with the user beyond the phrase 'consent question'. This is insufficient for an unannotated tool.

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?

The description is two short sentences, front-loads the key condition ('STEP 0 before install'), and wastes no words. The telegraphic style ('consent question + rule 0 + essentials + recent memory') is compact but slightly cryptic, which keeps it from a perfect score.

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?

Given four undocumented parameters, no annotations, and no output schema, the description is too sparse to let an agent call the tool correctly. It explains the when but not the how, leaving parameter usage and return behavior entirely undisclosed.

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 schema has 4 parameters with 0% description coverage (page, query, detail, session_id), and the description does not explain any of them. An agent receives no guidance on what these parameters mean or how to use them.

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 identifies this as the pre-install onboarding step that returns consent, rule 0, essentials, and recent memory, and explicitly distinguishes it from step_zero for post-install use. However, it uses telegraphic phrasing ('STEP 0') rather than a clear verb+resource statement, leaving the exact operation somewhat vague.

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?

It gives an explicit condition ('before install') and names the alternative sibling for the opposite state ('Once installed use step_zero'). The only gap is that it does not address other memory-related siblings like memory_search or memory_dig, but the primary routing decision is clear.

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