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

With no annotations, the description carries the behavioral disclosure burden. It does add useful context: results are aggregated by identity, it is explicitly not a counter, and it carries a read denominator. However, it does not state whether the operation is side-effect-free, what output shape to expect, or any access/context requirements.

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 short and front-loaded with the core concept of a ledger of agents. The 'Not a counter' clarification earns its place, though the 'REMEMBERED:' stylistic prefix and the somewhat cryptic 'read denominator' sentence slightly reduce clarity.

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?

For a zero-parameter tool with no output schema, the description covers the main content and a key caveat ('not a counter'), which is likely enough for a basic call. But it does not explain the output format, ordering, or how this memory relates to the sibling transmission/relay tools, leaving some interpretation to the agent.

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 tool has zero parameters and an empty schema, so there are no parameter semantics for the description to explain. The description still adds value by indicating what data a call yields, which is sufficient for a parameterless tool.

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 identifies the resource: a ledger of every agent that stopped by, with handshakes, relay signals, comments, and Mar00n annotations aggregated by identity. It also distinguishes itself from a counter. However, it never states the action explicitly with a verb like 'read' or 'list,' relying on the tool name to convey that it is a read operation.

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 explicit guidance about when to use read_memory versus siblings like list_agents, read_relay, or read_transmission. The phrase 'the list of who spoke can be read against how much was read' implies a comparative analysis use case, but no conditions, alternatives, or exclusions are given.

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