read_binary_slice

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It communicates that the operation is a read and that the result is hexadecimal, which is useful, but it does not disclose edge-case behavior, unit assumptions, or error conditions such as out-of-bounds offset or length.

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 a single, front-loaded sentence with no filler. Every word adds meaning, and it is appropriately sized for a simple read operation.

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?

The output schema likely covers return values, so the description need not explain them. However, the tool has three required parameters with zero schema-level descriptionsтной and no annotations. The omission of explicit byte-unit semantics and file path meaning leaves the definition only minimally complete for a straightforward tool.

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 compensate for the missing parameter documentation. It does not explain that 'path' refers to a file path, that 'offset' is a byte offset, or that 'length' is a byte count. The word 'bounded' hints at the offset/length relationship but does not provide enough semantic detail.

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 states a specific verb ('Read'), a specific resource ('binary slice'), and the output format ('as hexadecimal'). The phrasing 'binary slice' clearly differentiates this from the sibling read_text_excerpt, so an agent can identify the tool's role without inspecting the schema.

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?

The description gives no guidance on when to use this tool versus alternatives such as read_text_excerpt or extract_printable_strings. There is no stated exclusion, prerequisite, or explicit preference, so the agent must infer usage solely from the tool name and brief phrase.

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