Implementation Reference

• adapters/mcp/server-stdio.js:384-387 (handler)

  The handler for 'prevention_rules' (aliased from 'get_reliability_rules') which calls 'writePreventionRules'.

  case 'prevention_rules': {
    const outputPath = args.outputPath ? resolveSafePath(args.outputPath) : undefined;
    return toTextResult(writePreventionRules(outputPath, Number(args.minOccurrences || 2)));
  }

• scripts/feedback-loop.js:1097-1113 (helper)

  The implementation of 'writePreventionRules' which generates the markdown and registers it with the context system.

  function writePreventionRules(filePath, minOccurrences = 2) {
    const { PREVENTION_RULES_PATH } = getFeedbackPaths();
    const outPath = filePath || PREVENTION_RULES_PATH;
    const markdown = buildPreventionRules(minOccurrences);
    ensureDir(path.dirname(outPath));
    fs.writeFileSync(outPath, `${markdown}\n`);
  
    const contextFs = getContextFsModule();
    if (contextFs && typeof contextFs.registerPreventionRules === 'function') {
      try {
        contextFs.registerPreventionRules(markdown, { minOccurrences, outputPath: outPath });
      } catch {
        // Non-critical
      }
    }
    return { path: outPath, markdown };
  }

• scripts/tool-registry.js:195-202 (registration)

  Definition and registration of the 'get_reliability_rules' tool.

  readOnlyTool({
    name: 'get_reliability_rules',
    description: 'Retrieve active prevention rules and success patterns. Aliased to prevention_rules.',
    inputSchema: {
      type: 'object',
      properties: {},
    },
  }),
