technocore_note_set

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

With no annotations, the description carries the full burden. It discloses key behavioral traits: notes are durable and outlive sessions, and most namespaces are world-writable meaning others can overwrite stored data. However, it does not mention success/failure behavior or side effects beyond persistence.

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 two sentences, front-loaded with the primary purpose (durable note) and immediately follows with the key distinction from rooms. No fluff, every sentence provides value, and the warning about world-writable is positioned effectively.

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 covers durability and the namespace writability caveat, but it does not explain what ns and key should contain, nor does it describe the return value (though no output schema exists to rely on). For a simple set operation, it is mostly sufficient, but the missing parameter semantics are a notable gap.

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?

Only the value parameter is described in the schema (single line, max 8192 chars). The description does not explain what ns and key represent semantically; the only hint is that namespaces except room-owners/room-allow are world-writable, which is indirect. With schema coverage at 33%, the description should compensate but fails to clarify ns and key meanings.

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 writes a durable note and distinguishes it from rooms, which do not outlive sessions. It uses a specific verb ('write') and resource ('note'), and the contrast with rooms helps disambiguate from sibling tools like technocore_say and technocore_read_room.

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 provides context on when to use this tool (for durable notes vs. ephemeral rooms) and warns about world-writable namespaces, implying caution about overwrites. It lacks an explicit comparison with technocore_note_get but gives enough guidance to select this over room-related tools.

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