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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether it is a read-only planning operation, whether it calls external services, what it returns, or any prerequisites. The name implies planning but the text adds zero behavioral context.

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?

It is short, but this is under-specification masquerading as brevity rather than economy of information. Nothing is front-loaded because nothing of substance is present.

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 planning tool with three enum-driven parameters, no annotations, no output schema, and dozens of near-identical sibling plan tools, the definition is completely inadequate. An agent has no basis to select or correctly invoke it.

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 only 33% (appType has the useless gloss 'Application type.'), while targetSdk and backendMode have no descriptions at all despite being enums. The description text adds no meaning to any of the three parameters, so the schema gap is left entirely unmitigated.

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 is a bare restatement of the tool name plus a namespace prefix and the parenthetical '(headless-planner)'. No verb, no resource, no statement of what a 'headless integration plan' actually produces, and nothing distinguishes it from siblings like shared::backend.integration.guide or shared::widget.integration.plan.

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?

There is no guidance whatsoever on when to use this tool, what inputs are required, or which sibling plan tool to pick instead. An agent would have to guess based solely on the name.

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