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

Annotations already declare readOnlyHint, idempotentHint, closed-world, and non-destructive, so the safety profile is fully covered. The description adds 'live ... production,' implying current runtime state rather than cached documentation, which is useful context, but it says nothing about response scope or size.

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?

A single sentence that front-loads the verb and enumerates the covered topics with zero filler. Nothing in it is redundant with the schema or annotations.

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 zero-parameter, read-only, annotation-rich tool with no output schema, the description adequately signals what topics the result covers. The only gap is the missing routing guidance relative to abiyar_context and describe_capabilities.

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 tool takes zero parameters, so the baseline is 4; there is nothing for the description to disambiguate. The schema is trivially complete and consistent with the description.

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 ('Describe') tied to a concrete resource set: live Abyar production architecture, stages, sources, and MCP guardrails. It is clearly differentiated from data tools like abiyar_get_crop, but it does not distinguish itself from the closer siblings abiyar_context or describe_capabilities.

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 explicit guidance on when to call this instead of abiyar_context or describe_capabilities, both of which sound like overlapping orientation tools. The word 'live' hints at a runtime vs. static distinction, but the agent is left to infer it.

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