update_filter_segment

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

With no annotations, the description carries full burden. It discloses the replace behavior ('All fields are overwritten') and required scope, which are critical. However, it omits details like idempotency, side effects, or what happens if required fields are missing.

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?

Two sentences: first states the operation, second warns about overwriting and required scope. Front-loaded and no unnecessary words.

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?

For a simple update tool with 2 params and no output schema, the description covers main behavioral aspects but could include return value or error handling info. Adequate but not fully 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?

Schema coverage is 50% (only filterSegment has description). The description adds value by clarifying filterSegment as 'Full filter segment body to replace the existing one (name, isPublic, includes, etc.).' But uid parameter lacks any description in schema or description text.

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/replaces a filter segment by UID, with a specific verb and resource. It distinguishes from siblings like create_filter_segment and delete_filter_segment by specifying 'replace' and mentioning WRITE operation.

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 clear context: it replaces an existing filter segment, requires a specific scope, and all fields are overwritten. It implies usage for updating existing segments, but does not explicitly exclude alternatives or state when not to use.

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