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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuine context beyond that: recipes are self-contained, runnable, and guaranteed to typecheck against the components, which tells the agent output quality is assured. It stops short of describing return shape or pagination for the list mode.

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 opening sentence is long and front-loads a definition rather than the action, and the parenthetical component enumeration (Sidebar + Conversation History + AI Chat, with a phone drawer) is heavier than needed to convey purpose. The trailing two sentences are tight and earn their place.

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?

With one optional parameter, no output schema, and full annotation coverage, the definition is close to sufficient, but the absence of an output schema means the description should say what comes back for each mode (file bundle vs. list of slugs) and it only gestures at this with "Complete, runnable files."

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% for the single slug parameter, and the description's "Without a slug, lists the recipes" merely echoes the schema's own "Leave out to list the recipes." No additional semantics (format of slugs, error behavior for unknown slugs, list ordering) are added.

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 names the resource and characterizes it concretely ("Complete, runnable files that combine several Liro components") and enumerates example recipes, so an agent knows what a recipe is. It never states the verb directly ("returns"/"fetches") and gives no differentiation from close siblings like get_template or get_component_code, which keeps it short of a 5.

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 only usage signal is "Without a slug, lists the recipes," which is really restating parameter behavior rather than saying when to choose this tool over get_template, get_component, or get_component_code. No exclusions, prerequisites, or alternative-routing guidance is provided.

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