Returns high-quality existing spec files suitable as pattern references for test generation agents. Selected by structural complexity (most describe/context blocks) per spec category.
AI agents call get_well_tested_examples to retrieve information from Rails Insight without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing test specifications from the codebase to serve as reference examples. It performs passive information gathering—selecting and presenting spec files based on structural criteria (describe/context blocks). There are no side effects, no data modification, no code execution, and no irreversible actions.
From the tool's definition Tool returns existing spec files and pattern references; description uses 'Returns' indicating data retrieval with no modification capability. No mutation, deletion, or execution operations are implied.
Attacks that exploit this kind of access
Returns high-quality existing spec files suitable as pattern references for test generation agents. Selected by structural complexity (most describe/context blocks) per spec category. It is categorised as a Read tool in the Rails Insight MCP Server, which means it retrieves data without modifying state.
Register the Rails Insight MCP server in PolicyLayer and add a rule for get_well_tested_examples: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Rails Insight. Nothing to install.
get_well_tested_examples is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_well_tested_examples rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_well_tested_examples. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_well_tested_examples is provided by the Rails Insight MCP server (@reinteractive/rails-insight). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
