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

No annotations are provided, so the description carries the full burden of behavioral disclosure. However, it only mentions executing the CLI and referring to help, without describing what the tool does (e.g., sends prompts to a model, manages sessions), its effects (e.g., creates responses, modifies session state), or any constraints like rate limits or authentication needs. This is inadequate for a tool with multiple parameters and no structured annotations.

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 very brief with two short sentences, which is efficient but under-specified. While it avoids unnecessary words, the second sentence 'Use help for details' shifts responsibility rather than providing useful information, reducing its effectiveness. It's front-loaded but lacks substantive content.

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 the complexity (4 parameters, no annotations, no output schema), the description is severely incomplete. It doesn't explain the tool's function, parameter usage, behavioral traits, or output expectations. For a tool that likely interacts with a model or sessions, this leaves critical gaps in understanding how to use it correctly.

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%, meaning none of the 4 parameters (prompt, sessionId, resetSession, model) are documented in the schema. The description adds no information about what these parameters mean, their purposes, or how they interact (e.g., sessionId vs. resetSession). This leaves all parameters completely unexplained, failing to compensate for the schema gap.

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 'Execute Gemini CLI' states the tool's action but is vague about what resource it operates on. It doesn't specify whether this is for querying a model, managing sessions, or another function, and it doesn't distinguish from sibling tools like 'help' or 'listSessions'. The phrase 'Use help for details' suggests incomplete documentation rather than clear purpose.

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?

The description provides minimal guidance by mentioning 'Use help for details', implying that users should refer elsewhere for usage instructions. It doesn't specify when to use this tool versus alternatives like 'help' or 'listSessions', nor does it outline any prerequisites or contexts for invocation. This leaves the agent with little practical direction.

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