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

Adds real value beyond the blanket annotations: it discloses that 'list' is read-only, 'approve' clears the flag while preserving origin and trust weighting, and 'reject' archives the memory. This mode-level detail is not derivable from destructiveHint=true/readOnlyHint=false alone.

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?

Two tight sentences: the quarantine rationale first, then the per-action behavior. No filler and the default action is noted inline.

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?

No output schema exists, but the description focuses on behavior rather than return shape, which is appropriate. It leaves implicit that ids are required for approve/reject and does not describe what 'list' returns.

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 baseline is 3, but the description spells out what each enum value of 'action' actually does, adding meaning beyond the schema's terse 'What to do'. The 'ids' parameter still relies entirely on the schema.

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+resource (review/resolve memories pending verification) and immediately explains the quarantine mechanism that defines the resource. It is clearly distinguishable from siblings like brain_recall or brain_forget.

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?

Explains the three actions and their semantics, which implicitly tells the agent which mode to pick. It does not explicitly name sibling tools or state when a review workflow should be preferred over brain_recall, but the workflow context is clear.

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