memory_read

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

With no annotations, the description effectively discloses key behaviors: integrity verification, outbound screening, potential redaction of sensitive content, and blocking of tampered/policy-violating entries. This helps the agent understand side effects and constraints beyond a simple read.

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 extremely concise at two sentences, with the primary action in the first sentence. Every sentence adds value, and there is no redundant or irrelevant 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?

The description adequately covers behavioral aspects, but given the low schema coverage and zero parameter explanations, it feels incomplete. The existence of an output schema partially compensates for missing return value details, but parameter semantics are lacking, which reduces overall completeness.

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 description coverage is 0%, and the description provides no explanation for the 'key' and 'default' parameters. The purpose of 'default' (return value when key is missing) is not mentioned, leaving the agent to infer from the schema alone.

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 action ('Read a value') and the target resource ('guarded mem9 memory'). It is specific enough to understand the primary function, but does not differentiate from sibling tools like memory_list, which also reads memory in a different way.

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 guidance on when to use this tool versus alternatives. The description explains behavior during reads (integrity verification, redaction, blocking) but does not explicitly state when to choose memory_read over memory_list or other sibling tools.

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