Synthesis

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

There are no annotations, so the description carries the full burden of disclosing side effects. It only says 'manage' and lists action names; it does not state whether run mutates persistent state, whether revert is safe or idempotent, or what player_add/player_emove actually change.

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?

Two dense sentences front-load the purpose and then give use/non-use routing. There is no filler, repetition, or irrelevant context.

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 complex 9-parameter, 10-action tool, the description plus the fully documented schema provides enough to select and invoke the tool. It lacks explicit output-shape and side-effect notes, but those are partly covered by the schema's 'detail' and action descriptions, making this a minor gap rather than a blocking omission.

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 100%, so the baseline applies. The description adds no parameter-level meaning, but each of the nine properties is already documented in the input schema, so this is adequate.

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 a specific resource ('synthesis content'), a management verb, and the content subtypes it covers ('voice examples, lore templates, action patterns, and other enrichment'). It also explicitly excludes the codex sibling, so an agent can distinguish this tool from alternatives.

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 provides explicit 'Use when' and 'Do NOT use when' conditions, listing the relevant actions and naming the alternative for codex browsing. This gives the agent direct, actionable selection criteria.

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