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

No annotations are provided, so the description must carry the transparency burden. It does disclose meaningful behavioral scope by listing what the result includes: supporting evidence, assumptions, missing evidence, contradictions, unchecked dependencies, confidence, and invalidation conditions. However, it does not disclose side effects, read-only guarantees, or any dependencies on prior evidence-gathering steps.

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, efficient sentence that fronts the action ('Compile a final evidence result') and then details the result's contents. It is dense but not bloated; the enumeration is long but each item contributes meaning.

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?

The output composition is reasonably described, and an output schema exists, but the tool has no annotations, two undocumented parameters, and no usage guidance. An agent cannot confidently know what to pass or when to prefer this tool over closely related evidence tools, making the definition incomplete for correct invocation.

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%, and the description does not explain the meaning or relationship of task_structure_id or target_id. The agent is left to infer that task_structure_id identifies some task structure, while target_id's purpose is completely unexplained. The description does not compensate for the schema's lack of parameter 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 uses a specific verb, 'Compile', and identifies a clear resource, 'a final evidence result', while enumerating the exact content categories. It is clearly differentiated from siblings like audit_evidence_graph by focusing on producing a final consolidated result, though it does not explicitly name an alternative.

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?

There is no guidance about when to use this tool versus alternatives such as build_evidence_graph, audit_evidence_graph, or evaluate_claim_evidence. No exclusions, prerequisites, or contextual signals are given, leaving the agent to infer usage solely from the tool name and description.

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