verify_feature_release

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

No annotations are provided, so the description carries the full burden. It conveys only that Ed25519 signatures are involved; it says nothing about what verification checks, what a failed verification means, whether it is read-only, or what the caller should do with the result. Half the text is unrelated promotional material, which actively dilutes the behavioral signal.

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?

The one useful sentence is front-loaded, but three of four sentences are advertisement ('calibration that learns your printer', 'unlimited textures', upgrade link) that earn no place in a tool definition and obscure the actual contract.

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 four-parameter tool with no annotations and no output schema, the agent is left guessing about parameter meaning, required inputs (zero required parameters), return shape, and failure semantics. The single sentence about Ed25519 is the only substantive content, so the definition is inadequate for correct invocation despite the honest scope statement.

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 only 25% — only recompute_fingerprint has any documentation ('Default: false.'). feature_id, release_id, and release_name are entirely undocumented in both schema and description, and the description adds no meaning about identifier formats or how recompute_fingerprint affects the verification result.

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 first line states a specific verb and resource ('Verify an Ed25519 feature release'), which is genuinely informative. However, the remaining sentences are subscription-tier marketing copy that describe Kiln Pro features rather than the tool, and the description never distinguishes this tool from its obvious siblings verify_design_release, verify_decoration_preset_release, and sign_feature_release.

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?

There is no statement of when to use this verification versus signing, listing, or verifying a design/preset release. The 'Requires Kiln Pro' and upgrade-URL lines imply a gating condition without clarifying whether it applies to the tool call itself or to underlying product capability.

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