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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered structurally. The description usefully discloses the artifact's composition, but is silent on a genuinely important behavior: which API the descriptor is generated for, since the only parameter is an optional, non-ranking context string.

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?

A single dense sentence with the deliverable front-loaded, followed by the enumerated contents after an em-dash. Every clause carries information; nothing is padded.

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?

No output schema exists, so the description reasonably carries the burden of describing the artifact, which it does. However, for a generation tool with no required parameters it never explains the scope — which API, from what context — leaving a real gap for 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?

Schema description coverage is 100% and the context parameter is documented in unusually rich detail in the schema itself, so the baseline is 3. The description adds no additional semantics about the parameter or about how the target API is selected.

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?

States a specific verb ("Generate") and concrete artifacts (llms.txt, AGENTS.md), then enumerates the contract's contents (base URL, auth, operation table, deprecated operations, usage rules). An agent can picture the deliverable precisely, though it does not differentiate itself from the similarly-scoped sibling export_agent_rules.

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 when-to-use guidance, no prerequisites, and no named alternative. The sibling list contains export_agent_rules and gate_agent_context, which an agent could easily confuse with this tool, and nothing here resolves that choice.

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