C2.3/5.0
Behavior2/5

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

No annotations, so the description carries the full behavioral burden. It does disclose one meaningful trait (conditional execution on attestation), but leaves critical questions unanswered: what happens when not attested (error, no-op, rejection), whether this mutates or destroys state, what permissions are needed, and what is returned.

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

Conciseness3/5

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

One short, front-loaded fragment with no filler. However, the brevity here reflects under-specification rather than disciplined conciseness, so it earns only a middling score.

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

Completeness1/5

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

A tool taking two nested object parameters, with no annotations, no output schema, and no field-level documentation anywhere, is described by a single cryptic clause. An agent has essentially nothing to work with to invoke this correctly, making the description wholly inadequate for the tool's complexity.

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?

Both parameters are nested objects at 0% schema description coverage, so the description must compensate. Instead it merely repeats the schema property names ('execution', 'attestation') with no explanation of their expected shape, required fields, or the relationship between them. Near-zero added value for two opaque object parameters.

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

Purpose3/5

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

States a verb ('dispatch') and names the two inputs, plus a gating condition ('executes ONLY on ATTESTED'). However, 'PEP' and 'ATTESTED' are undefined internal jargon, so an agent cannot confidently tell what the tool actually performs or how it differs from siblings like attestation_check. The purpose is gestured at but not concretely stated.

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

Usage Guidelines2/5

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

The only usage-relevant information is the precondition that execution happens only when attested, and even that term is unexplained. There is no guidance on when to call this versus attestation_check, verdict_lookup, or probe, and no statement of required prerequisites or sequencing.

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