A3.8/5.0
Behavior4/5

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

Annotations already declare idempotent=true, destructive=false and closed-world, so the safety profile is given. The description adds real value beyond that: hard budget limits (65536 request bytes, 5 s execution) and the scope caveat that only software/model evidence is evaluated, which is not derivable from structured fields.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Four labeled clauses, purpose front-loaded, zero filler. Every phrase conveys a distinct fact (purpose, input, result, limits) rather than restating the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a validation tool it covers the essential shape and the execution envelope, and an output schema exists so return values need not be spelled out. But with a fully undocumented nested request object and four required opaque parameters, the description leaves the caller guessing about the actual request payload.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and there are four required parameters, so the description carries the burden. It only gestures at the contents of "request" (discrete state matrix, criteria) and says nothing about idempotency_key, schema_version, or the fixed max_total_price, leaving most of the contract unexplained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

"Accept or reject this bounded closed-loop model under the supplied stability criteria" names a specific verb (validate/accept-reject) and resource (closed-loop model + stability criteria), which cleanly separates it from siblings like validate_kinematic_dynamic_limits or diagnose_trajectory_instability. The Problem/Input/Result/Limits framing makes the outcome obvious.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the word "validate" and the criteria framing, but no statement says when to pick this over robotics_diagnose_trajectory_instability or robotics_compare_controller_responses, nor that it requires already-modeled discrete state matrices as input. The agent must infer the selection rule.

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