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

With no annotations, the description carries the full burden and does well: it discloses that this only 'records aggregate research evidence' and enumerates five side effects it does not perform (execute, charge, provision, queue, promise). It does not mention authentication requirements or what the call returns, but the non-effect disclosure is the highest-value behavioral fact here.

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 filler, and the core purpose is front-loaded ahead of the scoping caveat. Every clause carries information an agent needs.

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 no-annotation, no-output-schema tool with three parameters at 0% schema coverage, the definition covers non-effects well but leaves real gaps: horizon is undocumented, the slug format is only hinted at, and there is no guidance on how this relates to get_machine_capabilities. Adequate but not complete.

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%, so the description must compensate. 'Bounded technical slug' gestures at the requested_capability pattern constraint and 'category' maps to the enum parameter, but the third parameter, horizon (now/later/unspecified), is never mentioned and no format or example is given for the slug. Partial compensation only.

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 gives a specific verb (declare) and resource (a missing capability) qualified by 'bounded technical slug and category', which is far more precise than the title's vague 'Request ... for a Future Release'. It implicitly separates itself from the read-side sibling get_machine_capabilities by framing this as recording a gap, but it never names that sibling, so differentiation is left to inference.

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 second clause is unusually clear negative guidance: this tool 'will not execute, charge, provision, queue or promise future delivery', which tells the agent exactly what this call is not for. What's missing is positive routing — nothing says to check get_machine_capabilities first before declaring a capability missing, or when a request is appropriate versus redundant.

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