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

With no annotations provided, the description carries the full behavioral burden. It implies a read-only listing but says nothing about ordering, pagination beyond the limit parameter, retention window for 'recent', or permission requirements for viewing governed actions. The only behavioral content is the word 'governed', which is undefined.

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 or redundancy. It is efficient, though its brevity is achieved partly by omitting information the agent actually needs.

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?

An output schema exists, so return-value shape need not be explained in the description. However, for a tool with an undocumented parameter and no annotations, the description omits usage context and behavioral constraints that would make the definition self-sufficient.

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?

The single parameter 'limit' has 0% schema description coverage, so the schema supplies only a default (20) and bounds (1-200) with no stated meaning. The description adds nothing about what the limit counts or how ordering interacts with it, leaving the gap uncompensated.

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 names a specific verb (List) and resource (governed action executions) with a clear scope qualifier (recent, for the org). It is distinguishable from the write-side sibling memory_action_apply, but it does not explicitly differentiate itself from adjacent list-type siblings such as memory_episodes_list or memory_changes_since.

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?

There is no statement of when to use this tool versus alternatives, and no sibling is named as a routing target. The word 'recent' implies a recency-bounded read, but the agent must infer the usage context entirely.

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