C2/5.0

Behavior2/5

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

Annotations declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, and "keep" is consistent with a non-destructive write, so there is no contradiction. However, the description adds nothing beyond that: it doesn't say whether the draft is consumed, copied, or merely labeled, nor whether the referenced pack must already exist.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Seven words is brief, but this is under-specification rather than economy; a two-parameter write tool with no documented semantics needs more, not fewer, sentences.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The output schema means return values needn't be explained, but the description still omits the core operation semantics, parameter meaning, and routing versus other interests_* tools. It is not sufficient for an agent to invoke this confidently.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must carry parameter meaning, and it doesn't. "Launch draft" and "audience pack" loosely hint at draft_name and interest_pack_name, but nothing explains what identifier format is expected, whether interest_pack_name is optional, or what happens when it is omitted.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

"Keep a launch draft as an audience pack" gestures at a verb and two resources, but "keep" is undefined and the relationship between a draft and an audience pack is unclear (save? convert? duplicate?). It does not distinguish this from siblings like interests_save_fetched_pack or interests_save_targets.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance, no preconditions, and no mention of the closely related interests_save_* or interests_use_targets tools. The agent must guess which of the interests_* family applies.

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