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

Beyond the supplied annotations, it discloses partial-patch behavior, a permission-check prerequisite, and a result containing the updated topic and current permissions. It does not explain what destructiveHint means in practice, particularly whether arrays or nested objects are replaced, merged, or cleared.

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?

Three short paragraphs front-load the operation and patch semantics, then cover the prerequisite and returned result. Every sentence serves a distinct purpose without filler or unnecessary schema repetition.

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 workflow and return-value information make the definition adequate for a straightforward update, and annotations supply the broad safety profile. For an eight-parameter nested mutation without an output schema, however, the missing field semantics and replacement or removal rules leave significant invocation 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?

With only 13% schema description coverage, the description needs to compensate but explains no individual field beyond the already-documented ID. The general patch rule is useful, yet parentId, validFrom, validUntil, references, classification, and most nested-field update behavior receive no additional semantic guidance.

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?

“Update an existing topic” states a specific verb and resource, while the patch wording clarifies that only selected fields are changed. It does not explicitly distinguish itself from engramic_create_concept or the other engramic_update_* siblings, so sibling routing remains partly implicit.

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?

It provides a concrete prerequisite: retrieve the topic by ID with engramic_topic to confirm its existence and check permissions before updating. However, it gives no explicit when-not-to-use guidance or pointer to engramic_create_concept when the topic does not yet exist.

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