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 discloses that the default returns only a hash, that 'light=True' returns field arrays at mesh levels 2–5, and that the reading is 'chained and never served'. However, these disclosures are wrapped in obscure language ('unsworn', 'poles' eyes', 'measured magnet's zeros') that obscures rather than clarifies actual behavior. It does not state side effects, permissions, or failure modes.

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 description is long and dense with metaphor, but the key information (default hash, light option, mesh levels) is buried in figurative language. It is not front-loaded with a plain statement of purpose. Every sentence is stylized, which hurts scannability for an agent.

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?

Given no output schema and no annotations, the description is incomplete. It does not explain the return format beyond 'hash' and 'field arrays', does not specify the meaning of 'slice' clearly, and does not describe error conditions or relationship to sibling tools. The reference to 'open_ground()' hints at a workflow but does not clarify it.

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 explain the parameters. It explains 'light' as a boolean that toggles returning 'the light' (field arrays), and 'slice' is mentioned only as 'mesh level (2–5)' in the context of light=True. The description does not clearly map 'slice' to the integer parameter, nor explain its default behavior or range. The poetic phrasing adds ambiguity rather than clarity.

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 is poetic and metaphorical ('the newest tick of the Earth, free', 'the clock and the chain's links', 'the commitment a stamp binds to'), making it difficult for an agent to determine what concrete action 'tick' performs. It mentions returning a hash by default and optionally 'light' field arrays, but the core function remains obscured by figurative language. It does not clearly distinguish itself from siblings like 'stamp' or 'attest'.

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 explicit guidance on when to use this tool versus alternatives. The description references 'open_ground()' as a way to open the face, but does not explain when to choose 'tick' over 'stamp', 'attest', or 'ground'. The usage context is implied through metaphor rather than stated.

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