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 implies a write ("Record") but says nothing about whether the record is append-only or mutable, whether it updates a reputation score, whether it requires prior agent registration, or whether it is idempotent. For a state-mutating reputation tool this is a substantial gap.

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?

It is short, but brevity here reflects under-specification rather than tight writing. A single fragment cannot front-load the information an agent needs, so there is no structure to evaluate beyond its minimal length.

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 4-parameter, 3-required mutation tool with no annotations, no output schema, and 0% schema description coverage, the description is far too thin. An agent has no way to know required input formats or the side effects of recording an interaction, though the terse purpose statement at least prevents total ambiguity.

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 mentions no parameters at all. Three of four parameters are required (agent_id, interaction_type, outcome) and one has an enum, yet the description adds zero meaning about expected formats, valid interaction_type values, or the optional counterparty_id.

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 gives a verb and a resource ("Record agent interaction"), so the basic operation is identifiable. However, it never clarifies what an "interaction" is in this system, what recording it does to reputation state, or how it differs from siblings like agents_reputation, receipt_reputation, or trust_history, leaving the purpose only loosely pinned down.

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 when-to-use guidance, no prerequisites, and no reference to any alternative tool. The only contextual cue is the bracketed "[agents]" tag, which hints at scope but does not tell an agent when this call is appropriate versus the many other agent- and trust-related siblings.

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