Single tool 'echo' has a basic description and input schema, but falls far short of production quality. Description is minimal (28 chars, below 34-char p10 baseline). No output schema documented. No error handling guidance. No parameter constraints or validation hints. Tool lacks context about when/why to use it vs alternatives. No mention of idempotency, side effects, or recovery paths. Schema present but sparse, only 'message' param with basic string type, no format/length constraints. Missing 94% of A+ tool patterns.
Echo a message back to the client.
Tool description is 28 characters, below p10 baseline (34 chars). Lacks WHAT, WHEN, and WHY context. LLMs cannot determine when to select 'echo' vs other tools or what it returns.
No output schema documented. LLMs cannot plan downstream calls or extract return values. Violates pattern:tool requirement for structured output.
Input parameter 'message' lacks constraints: no min/max length, no format hints, no validation rules. LLMs will pass arbitrary strings without guidance.
No error handling guidance. Tool description does not explain failure modes, recovery steps, or when to retry. Violates pattern:recovery-guide.
Tool name 'echo' is generic and does not follow verb_noun convention. Does not clearly convey action. Should be 'echo_message' or 'return_message' for clarity.
