link_test_cycles_to_plan

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

No annotations are provided, so the description must carry full burden. It only states the operation and return code (204), but does not disclose whether links are appended or overwritten, idempotency, authentication requirements, or error conditions. Minimal behavioral insight beyond the obvious.

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, no unnecessary words. Efficiently communicates purpose, parameter details, and return code. Could be slightly improved with bullet points, but acceptable.

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?

Covers return value and parameter sources, but misses important context like whether linking is idempotent, if cycles must exist, or error handling. Given simplicity of tool and lack of annotations, more completeness would help agent.

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 has 100% description coverage, baseline is 3. Description adds value by telling the agent to use the plan's internal ID and reinforcing that testcycleIds are numeric integers. This goes beyond the schema's brief descriptions.

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?

Clearly states the tool links existing test cycles to a test plan, using specific verb and resource. Distinguishes from sibling tools like unlink_test_cycles_from_plan and create_test_cycle.

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?

Provides guidance on obtaining the plan ID from get_test_plan or search_test_plans, and specifies that testcycleIds are numeric. However, it does not explicitly state when to use this tool versus alternatives like creating a new cycle.

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