flash_image

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

With no annotations, the description carries the burden of disclosing behavioral traits. It mentions that the operation is persistent, requires explicit confirmation, and depends on flash erase/programming being enabled. It also notes the path allowlist constraint. Missing details about failure modes or return behavior, but core safety-relevant information is present.

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 concise, with three sentences each contributing value. It front-loads the main purpose, then adds key constraints and options without unnecessary fluff.

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 description provides essential safety and prerequisite context for a complex flash operation, but it omits explanations for several parameters (address, verify, confirm, reset_after) and does not describe expected outputs or error conditions. Given no annotations or output schema, it is somewhat incomplete for an agent to fully understand tool behavior.

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. It adds meaning for 'path' (allowlist restriction) and 'erase_mode' (sector/chip), but does not explain 'address', 'verify', 'confirm', or 'reset_after' beyond what their names imply. Thus it only partially covers the parameter semantics.

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 clearly states the tool's action ('Flash a raw binary file') and its operations ('erase, program, verify, and optional reset'). The phrase 'raw binary file' distinguishes it from sibling tools like flash_firmware, which likely handles firmware images.

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?

Usage context is implied via 'raw binary file' and 'persistent operation', but the description does not explicitly say when to use this tool instead of alternatives like flash_firmware. It mentions prerequisites (confirmation, flash erase/programming enabled) but no explicit when-to-use or when-not-to-use guidance.

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