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

Annotations already declare readOnlyHint, idempotentHint and non-destructive, so the safety profile is covered. The description adds useful return-shape context (singleton persona, compact skill, server and memory metadata), but does not explain pagination behavior of memory metadata or what happens when the playbook id is unknown.

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?

A single front-loaded sentence with no filler; the resource and payload contents come first. It is dense but every phrase carries information.

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?

With no output schema, the description does a fair job naming the returned components, but a four-parameter read tool with paging and a full-payload mode would benefit from a sentence on error cases or when to prefer include_content=false plus targeted reads.

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 four parameters are documented, including the compact-mode paging and the include_content restore flag. The description adds nothing parameter-specific beyond the word 'compact', so the baseline 3 applies.

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 (get a playbook) and enumerates what comes back: persona, compact skill, connected-server and memory metadata. It does not distinguish itself from list_playbooks or get_skill, so an agent must infer the boundary from the name alone.

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 on when to call this versus list_playbooks (discovery) or get_skill (detailed skill retrieval). The description never mentions the include_content tradeoff or that memory_limit/offset only apply in compact mode, leaving routing to the agent's guesswork.

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