cueapi_get_cue

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

With no annotations provided, the description carries the full burden. It discloses that this is a read operation ('Fetch') and specifies what data is included (schedule and execution), which helps the agent understand the tool's behavior. However, it doesn't mention potential errors (e.g., invalid ID), performance characteristics, or authentication needs.

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, well-structured sentence that efficiently conveys the tool's purpose and scope without unnecessary words. It's front-loaded with the core action and resource.

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 low complexity (single parameter, no output schema, no annotations), the description is reasonably complete. It explains what the tool does and what data it returns, though it could benefit from mentioning error cases or output format to fully compensate for the lack of annotations and output schema.

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%, so the schema already documents the single parameter cue_id with its type and format. The description doesn't add any additional parameter details beyond what's in the schema, such as validation rules or examples beyond the schema's 'e.g.'.

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 specific action ('Fetch'), resource ('a single cue by ID'), and scope ('including current schedule and most recent execution'). It distinguishes from siblings like cueapi_list_cues (which lists multiple cues) and cueapi_list_executions (which focuses on executions).

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 context by specifying 'by ID' and mentioning schedule/execution details, suggesting it's for retrieving detailed information about a specific cue. However, it doesn't explicitly state when to use this versus alternatives like cueapi_list_cues for overviews or cueapi_list_executions for execution history.

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