ht_trendmode

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

With no annotations provided, the description carries the full burden of behavioral disclosure but fails to do so. It does not indicate whether this is a read-only or mutative operation, any rate limits, authentication needs, or what the output entails (e.g., data format or potential side effects).

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 concise with a single phrase, but this brevity leads to under-specification rather than efficiency. It is front-loaded but lacks necessary detail, making it insufficiently informative despite its short length.

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 implied by the tool name (involving Hilbert transforms and trend analysis), 4 parameters with 0% schema coverage, no annotations, and no output schema, the description is completely inadequate. It does not provide enough context for an agent to understand or use the tool effectively.

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 (symbol, interval, month, datatype) are documented in the schema. The description adds no information about these parameters, such as their purposes, expected formats, or examples, failing to compensate for the lack of schema documentation.

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 'Fetch hilbert transform - trend mode' restates the tool name 'ht_trendmode' with minimal elaboration, making it tautological. It specifies a verb ('Fetch') and resource ('hilbert transform - trend mode'), but lacks clarity on what the Hilbert transform is or what 'trend mode' entails, and does not distinguish it from sibling tools like 'ht_dcperiod' or 'ht_sine'.

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 no guidance on when to use this tool versus alternatives. It does not mention any context, prerequisites, or comparisons to sibling tools, leaving the agent without direction on appropriate usage scenarios.

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