update-filters

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

Annotations already indicate destructiveHint=true and readOnlyHint=false, but the description adds no additional behavioral context. It does not state that updates irreversibly overwrite values, that filters are personal rather than shared, or mention any side effects. The description is too shallow to fully inform the agent about the tool's behavior.

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 a single, front-loaded sentence with no redundant words. It clearly communicates the core action and scope without unnecessary elaboration, achieving excellent conciseness.

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 tool's moderate complexity (array of nested objects), the description is adequate but minimal. It lacks usage guidance and behavioral transparency, but the output schema and annotations cover some context. The description is not fully complete for an agent to confidently decide when to use it, but it's not misleading.

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 100%, with detailed descriptions for all properties (e.g., color enum with default behavior, query examples). The description adds no extra parameter meaning, but baseline score of 3 is appropriate since the schema carries the full burden and the description doesn't introduce confusion.

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 updates existing personal filters, using a specific verb ('update') and resource ('existing personal filters'). It distinguishes from sibling tools like add-filters and find-filters by explicitly saying 'existing', indicating modification rather than creation or retrieval.

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 modifying already-created filters, but does not explicitly mention alternatives or exclusion criteria. No reference to find-filters or add-filters is provided, so the agent must infer the appropriate context from the word 'existing'.

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