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

With no annotations, the description carries the full burden and does well: it discloses that this is a soft "forget" rather than a hard purge (the result can be suggested again) and that it has a training side effect ("its score no longer trains"). It still omits permission requirements and whether the effect is immediate/undoable, so not a 5.

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: the endpoint, the action, and the two consequences of the action. Every clause earns its place with no filler.

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 values need no explanation, and the description supplies the key mutation semantics that annotations would otherwise cover. The remaining gap is parameter-level detail for nid/eid, which matters given 0% schema coverage.

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 coverage is 0% and neither nid nor eid is documented in the schema. The path template "/nodes/{nid}/edges/{eid}" does clarify that nid identifies the node and eid the edge, which is real added meaning, but it gives no format, type, or provenance guidance for the two undocumented parameters.

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?

States a specific verb (DELETE/forget) on a specific resource (edge) and immediately explains what an edge deletion means semantically: the result can be suggested again and stops training. That is far more than a tautology. It does not explicitly contrast itself with update_edge or put_edge, so it falls short of a 5.

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?

"forget a result, so it can be suggested again" implies the usage context (undoing a previously accepted/suggested edge rather than removing a node or editing an edge), but there is no explicit when-to-use/when-not statement and no named alternative among the many edge siblings.

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