Single tool ('get') with sparse schema and minimal parameter documentation. The tool has a valid input schema (url as required string) and a brief description, but lacks critical elements expected in production tools: parameter descriptions, output schema documentation, error guidance, and enum constraints. The description (80 chars) is adequate but generic. No pagination support despite operating on HTTP responses that could be large. Error handling exists but provides minimal recovery guidance.
Sends a GET request to the specified URL and returns a Response object
Parameter 'url' lacks description in tool specification. The input schema declares url as a string type but provides no guidance on format, validation, or constraints (e.g., must be valid HTTP/HTTPS URL, character limits, encoding). LLMs cannot infer what values are valid.
Output schema is not documented. The tool returns a formatted text response with status code, headers, and body embedded in plain text. No structured schema definition tells LLMs what fields are available or how to extract data for downstream tool calls.
Tool description is generic and lacks context. 'Sends a GET request to the specified URL and returns a Response object' (80 chars) states WHAT it does but not WHEN to use it vs other tools, what Response object structure to expect, or common failure modes.

No error guidance for LLM recovery. When a request fails (invalid URL, timeout, non-JSON response), the tool returns text-wrapped errors like 'Error: Invalid arguments for get request'. The LLM receives no hint on whether to retry, validate input, or try an alternative tool. Per pattern:recovery-guide, error responses must guide the agent.
Assumes JSON response body. Tool calls await response.json() without checking Content-Type or catching JSON.parse errors. If the server returns HTML, plain text, or binary data, the tool will crash with a generic error. LLMs cannot recover from 'Failed to parse JSON' without guidance on alternative formats or fallback strategies.
No URL validation or constraint hints. Parameter 'url' accepts any string.
No timeout specification or guidance. Tool calls external HTTP services but does not declare timeout behavior, expected response time, or what happens if a server hangs.
Unbounded response size risk. Tool returns full headers and JSON body in plain text without size limits or pagination. A large API response (>10KB) bloats the response and wastes tokens.
