Detect Timeline Conflicts & Generate Mermaid Gantt

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It mentions analysis and chart generation but omits the fact that the tool accepts an optional 'addEvent' parameter, implying it can modify the timeline. This is a significant undisclosed side-effect for a tool that might otherwise appear read-only.

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 two concise sentences, front-loaded with the core action (analyze) and the output (Gantt chart). No unnecessary words or 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 description adequately covers the main purpose of conflict detection and Gantt generation. However, given the presence of an optional nested 'addEvent' parameter and no output schema, it would be more complete if it explained the event-adding behavior and the expected response format. Still, the core functionality is clearly captured.

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 100% and the schema includes descriptions for 'addEvent' and all its nested properties. The description adds no parameter-level detail, but per the baseline rule this is acceptable when the schema is fully self-explanatory.

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 tool's function: analyze absolute and relative timeline milestones and events to detect conflicts, then output a Mermaid Gantt chart. This specific verb+resource pairing distinguishes it from sibling analysis tools like story_analyze_pacing or story_analyze_voice.

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 clear context that this tool is for detecting timeline conflicts and generating a visualization. It does not explicitly name alternatives or exclusions, but the intended use case is evident from the purpose statement.

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