get_lifecycle_gaps

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

Annotations already declare read-only, idempotent, and non-destructive behavior, so the description adds little behavioral context. It only describes the content of the return value (timestamp, identity, missing-parent evidence) rather than any side effects, errors, or performance characteristics. Since the description does not contradict annotations but also does not enhance them, a score of 2 reflects the minimal contribution beyond the structured metadata.

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 short sentence, which is technically concise, but it lacks the substance needed to be useful. Under-specification is not true conciseness; the sentence could be expanded substantially without adding fluff. It is not front-loaded with the most important information because there is almost no information at all.

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 likely purpose (identifying lifecycle gaps) and the existence of an output schema, the description still does not explain what triggers a gap, how to interpret the evidence, or when to call this function. It omits any context about the lifecycle model or the relationship to artifact_id. The description is incomplete for an agent to confidently invoke the tool.

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 the schema provides no description for either parameter. The tool description does not mention artifact_id or limit at all, so the agent receives no guidance on what these parameters mean, their purposes, or how they affect the response. This is a significant gap for a required parameter.

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 states a specific verb ('Return') and a resource ('explicit timestamp, identity, and missing-parent evidence'), which conveys a clear action but leaves the meaning of 'lifecycle gaps' ambiguous. It does not distinguish this tool from the many other evidence-returning siblings (e.g., get_evidence, summarise_evidence) beyond the name, so an agent may struggle to know exactly what this tool offers.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of scenarios, exclusions, or conditions that would select this over the many related tools. The agent is left to infer usage solely from the tool name.

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