rynmesh_read_messages

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

No annotations are provided, so the description carries the full burden. It discloses a concrete behavioral prerequisite: 'requires the local node daemon to be running.' The verb 'Read' also implies a read-only, non-destructive operation. However, it does not describe expected output, failure modes, authentication needs, or side effects.

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 a single, front-loaded sentence with no filler, and the parenthetical adds a useful prerequisite. It is concise and readable, though slightly under-specified overall.

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 tool with no annotations, no output schema, and 0% schema description coverage, the description is too thin. It provides the core action and a prerequisite, but leaves parameter semantics, return behavior, and operational boundaries unspecified.

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%, so the description must compensate, but it does not explain either parameter. 'With a peer' vaguely hints at peer_id, and limit is completely unexplained. The description adds no value beyond the raw schema structure.

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 uses a specific verb and resource: 'Read the message history with a peer.' This clearly states the tool's function and is distinct from siblings like rynmesh_send_message, though it does not explicitly name or differentiate sibling tools. It is clear but not maximally differentiated.

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?

The description gives some usage context by noting that the local node daemon must be running, which is a practical precondition. However, it does not mention when to use this tool versus alternatives or when not to use it, so the guidance is implied rather than explicit.

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