nmem_remember_batch

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

With no annotations, the description carries the full behavioral burden and delivers a genuinely non-obvious trait: partial success, where one bad item won't block the rest. It also notes the max-20 cap, though it says nothing about persistence, permissions, or response shape.

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?

Three compact sentences, each carrying a distinct fact (scope, threshold, failure mode), with the core capability front-loaded. No filler.

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 batch write tool with no annotations and no output schema, the description covers purpose, when-to-use, and failure semantics well. It lacks any mention of what a successful call returns or its persistence guarantees, which would round out the picture.

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 coverage is 100%, so all three top-level parameters and nested memory fields are documented in the schema itself. The description's 'max 20' merely repeats maxItems already present, adding no new parameter meaning. Baseline 3 is correct.

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?

States a specific verb and resource ('Store multiple memories at once') plus a hard constraint (max 20). The plural scope implicitly contrasts with the singular nmem_remember sibling, though it never names it.

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?

Gives an explicit trigger condition: 'Use when saving 3+ memories together.' This routes the agent away from the single-item tool, but it does not name nmem_remember directly nor state when to prefer it explicitly.

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