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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states 'Update an existing quest,' which implies a mutation operation, but doesn't describe critical behaviors like whether it overwrites or merges fields, what permissions are required, if changes are reversible, or what happens on failure. For a mutation tool with zero annotation coverage, this leaves significant gaps in understanding how the tool behaves.

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, direct sentence with zero wasted words. It's front-loaded with the core action ('Update') and resource, making it easy to parse quickly. Every word earns its place by conveying the essential purpose without redundancy or fluff.

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?

Given the complexity (a mutation tool with nested parameters), lack of annotations, and no output schema, the description is incomplete. It doesn't address behavioral traits, parameter meanings, or return values, leaving the agent with insufficient context to use the tool effectively. For a tool that modifies data in a knowledge graph, more detail is needed to ensure correct invocation.

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?

The schema description coverage is 0%, meaning none of the parameters (e.g., 'name', 'status', 'objectives') are documented in the schema. The description adds no information about these parameters—it doesn't explain what fields can be updated, their purposes, or how they interact. With 1 parameter (a nested object) and no schema descriptions, the description fails to compensate, leaving parameters entirely undocumented.

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 states the verb ('Update') and resource ('an existing quest in the knowledge graph'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'add_quest' or other update tools (e.g., 'update_artifact'), which would require mentioning quest-specific aspects or contrasting with creation operations.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing quest ID), contrast with 'add_quest' for creation, or specify scenarios where updating is appropriate (e.g., versus deleting). Without such context, the agent must infer usage from the tool name alone.

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