get_chain_status

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds that the call is lightweight and what fields it reports, which is modest extra context but says nothing about cost, pagination, or failure modes.

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 front-loaded fragment with no filler words; the essential content (status fields returned) leads. It is efficient, though arguably so terse that it crosses into under-specification rather than pure conciseness.

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?

Because an output schema exists, return values needn't be spelled out, and safety is covered by annotations. What is missing is the routing information an agent needs: why this lightweight check rather than read_chain or check_chain_health, and any semantics for chain_id.

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?

Only one parameter (chain_id) with schema description coverage at 0% – the schema gives just 'Chain identifier' with no format, accepted values, or scope. The description does not compensate at all, so the agent gets no guidance on what a valid chain identifier looks like.

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?

States the resource (chain status) and enumerates exactly what it returns: current link, phase, and health. It is clear what the tool surfaces, but it offers no differentiation from close siblings like read_chain or check_chain_health, leaving the agent to guess which status-oriented tool applies.

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 word 'lightweight' hints at a preference for this over heavier reads, but there is no explicit when-to-use statement, no prerequisites, and no named alternative among read_chain, check_chain_health, or search_chains.

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