C2.8/5.0
Behavior2/5

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

No annotations are provided, so the description must carry the full behavioral burden. It mentions automated patch synthesis and canary verification, but does not clarify whether patches are applied or only generated, whether operation is read-only or mutating, what permissions are needed, or what the response looks like.

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?

The definition is a single sentence and front-loads the core auditing purpose, so it is compact. However, it is a dense run-on list with eight CWE identifiers and multiple feature phrases, which hurts readability and does not separate purpose from behavior.

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

Completeness2/5

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

This is a complex audit tool with seven parameters, no annotations, and no output schema. The description covers the general purpose but leaves out usage conditions, prerequisites, return behavior, and side-effect clarity, which are important for confident invocation.

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

Parameters3/5

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

Schema description coverage is 100%, so all seven parameters are already documented in the input schema. The description adds no parameter-specific syntax, defaults, or usage distinctions beyond the schema, making the baseline 3 appropriate.

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

Purpose4/5

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

The description gives a specific verb and resource: auditing In-toto supply chain metadata, DSSE envelopes, SLSA provenance, and Rekor proofs. It is clearly distinct from most siblings, but it does not explicitly differentiate itself from close alternatives such as audit_cosign, audit_sbom, or audit_model_supply_chain.

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 description states what the tool audits but gives no when-to-use guidance, no prerequisites, and no exclusions. With many sibling audit tools, an agent receives no routing signal about when this tool is preferred over audit_cosign, audit_sbom, or audit_cicd.

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