Zephyr: Get Test Cycle Links

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the return categories (issues, web links, test plans), but it does not disclose behavioral details such as response pagination, empty results, or error behavior for an invalid cycle key.

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 well-structured: a one-sentence definition, a short parameters section, then examples in a scannable JSON format. The two examples are somewhat repetitive and repeat the expected output, but the overall size is reasonable and front-loaded with the core purpose.

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 read-only operation with one required parameter, strong annotations, and an output schema, the description is complete. It identifies the target test cycle, enumerates the three link categories returned, and provides valid examples for both id and key formats, leaving no critical calling information missing.

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 schema already documents the single required parameter with a regex pattern, so the baseline is 3. The description adds value with two concrete examples showing both valid forms — numeric id '1' and key 'SA-R40' — and clarifies the expected output for each, which helps the agent format the parameter correctly.

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 opens with a specific verb-resource-object statement: 'Get all links (issues, web links, and test plans) associated with a test cycle in Zephyr.' This clearly distinguishes it from sibling tools like zephyr_get_test_cycle (cycle details) and zephyr_get_test_case_links (links on a different entity).

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 when to use the tool by stating it retrieves test-cycle links, and the 'Toolset: Test Cycles' label places it in context. However, it does not explicitly tell the agent when to prefer this over zephyr_get_test_cycle, zephyr_get_test_execution_links, or the link-creation tools, nor does it state any exclusions.

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