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

The description's verbs (predict, identify, warn) suggest a read-only, advisory tool, but it never explicitly states that it will not delete or modify files, what the warning mechanism is, or whether any side effects (e.g., notifications) occur. With no annotations to declare safety, the description takes full responsibility but leaves some behavioral ambiguity.

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 one sentence, front-loads the core capabilities, and contains no waste. Every clause adds information, and the structure is easy to parse.

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 a zero-parameter, no-output-schema tool, the description gives a reasonable high-level overview of what the tool accomplishes. It is somewhat general and does not define the output or warning format, but for a no-input analytical agent, it is mostly complete.

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 has zero parameters, so there is no parameter semantics to convey. A baseline score of 4 is appropriate because no parameters need explanation and the description does not introduce unnecessary parameter-related content.

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 clearly states the tool's specific purpose: predicting disk usage trends, identifying safe cache directories to prune, and warning about impending no-space events. The resource (disk space) and three distinct actions are explicit, distinguishing it from broader sibling tools like timps_system_optimizer or timps_privacy_cleaner.

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 implies usage for disk-space planning and safe cache cleanup but provides no explicit guidance on when to use it versus alternative tools. It does not mention exclusions, prerequisites, or scenarios where another tool (such as timps_privacy_cleaner or timps_system_optimizer) would be preferred.

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