binary.save

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

With no annotations, the description must carry the full behavioral disclosure. It only says 'save,' which implies a write operation, but does not mention whether it overwrites existing files, requires specific permissions, or is destructive. No details on error behavior or side effects.

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 extremely short (one sentence, 8 words). While concise, it sacrifices critical information. It is front-loaded with the action, but every word is necessary – yet insufficient. A 3 reflects that brevity is achieved but at the cost of clarity.

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, no annotations, and two parameters, the description is grossly incomplete. It does not explain what happens on success, what is returned, error cases, or even the format of the file. The agent lacks essential context for correct invocation.

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 should compensate. It fails to explain either parameter: 'path' (likely the output file path) and 'session_id' (which session's binary view?). The parameter names are suggestive but not defined, leaving the agent to guess.

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 action ('Save') and the resource ('current binary view'), with a target ('to a file path'). This is specific enough to distinguish from other tools like binary.summary or binary.functions, though it does not explicitly differentiate from database.save.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., database.save_bndb, session.save). There is no mention of prerequisites, context, or when not to use it. The agent must infer usage from the name alone.

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