Set overview

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

Annotations only say readOnlyHint=false and destructiveHint=false; the description adds substantive behavior: exact deep-link syntax that becomes clickable chips at build, demotion of invalid node links to plain text with a build warning, and guaranteed validation before shipping. It does not discuss whether existing overview content is replaced, but 'set' implies that.

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 dense sentences with no filler; the most important content type is front-loaded, and the link syntax is given exactly. The final clause about validation is slightly redundant with the preceding warning but adds a safety guarantee.

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 is sufficient for the overview_html format and validation behavior, but omits overwrite semantics and any rationale for the required timeline_id. It also does not clarify whether 'optional' means the panel can be empty despite overview_html being required.

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 schema description coverage at 0%, the description must carry param semantics. It does this for overview_html by specifying HTML paragraphs and the exact link format, which the bare schema lacks. timeline_id is only inferable from its name and the tool name, so the compensation is incomplete.

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 identifies the tool as an 'Optional prose overview panel (HTML paragraphs)', which clearly states the resource and content type. It goes beyond the title 'Set overview' by explaining what the panel contains, though it never uses an explicit verb like 'sets/updates'. It distinguishes from sibling tools because none of them target the overview panel.

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 implies usage in the authoring workflow ('Authored from the user's material (§0)') and refers to build-time behavior, so an agent can infer when it applies. It does not explicitly state when to prefer this tool over siblings like build_timeline or add_nodes, nor provide when-not-to-use conditions.

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