src/tools/metadata.ts:184-223 (handler)

The handler function for the 'system-health-check' tool. It collects system health information including status, timestamp, uptime, memory usage, environment details, and tool counts, then formats and returns it.

handler: async () => {
    try {
        const healthInfo = {
            status: 'healthy',
            timestamp: new Date().toISOString(),
            uptime: process.uptime(),
            memory: {
                used: Math.round(process.memoryUsage().heapUsed / 1024 / 1024),
                total: Math.round(process.memoryUsage().heapTotal / 1024 / 1024),
                external: Math.round(process.memoryUsage().external / 1024 / 1024)
            },
            environment: {
                nodeVersion: process.version,
                platform: process.platform,
                arch: process.arch
            },
            tools: {
                database: databaseTools.size,
                metadata: tools.size,
                total: databaseTools.size + tools.size
            }
        };

        return {
            content: [{
                type: 'text',
                text: `Estado de salud del sistema:\n\n${formatForClaude(healthInfo)}`
            }]
        };
    } catch (error) {
        logger.error('Error in health check:', { error });
        return {
            content: [{
                type: 'text',
                text: `Error en verificación de salud: ${error instanceof Error ? error.message : String(error)}`
            }],
            isError: true
        };
    }
}

src/tools/metadata.ts:180-224 (registration)

Registers the 'system-health-check' tool in the metadata tools Map, defining its title, description, empty input schema, and handler function.

tools.set('system-health-check', {
    title: 'System Health Check',
    description: 'Verifica el estado de salud del sistema y la conectividad de la base de datos',
    inputSchema: z.object({}),
    handler: async () => {
        try {
            const healthInfo = {
                status: 'healthy',
                timestamp: new Date().toISOString(),
                uptime: process.uptime(),
                memory: {
                    used: Math.round(process.memoryUsage().heapUsed / 1024 / 1024),
                    total: Math.round(process.memoryUsage().heapTotal / 1024 / 1024),
                    external: Math.round(process.memoryUsage().external / 1024 / 1024)
                },
                environment: {
                    nodeVersion: process.version,
                    platform: process.platform,
                    arch: process.arch
                },
                tools: {
                    database: databaseTools.size,
                    metadata: tools.size,
                    total: databaseTools.size + tools.size
                }
            };

            return {
                content: [{
                    type: 'text',
                    text: `Estado de salud del sistema:\n\n${formatForClaude(healthInfo)}`
                }]
            };
        } catch (error) {
            logger.error('Error in health check:', { error });
            return {
                content: [{
                    type: 'text',
                    text: `Error en verificación de salud: ${error instanceof Error ? error.message : String(error)}`
                }],
                isError: true
            };
        }
    }
});

src/tools/metadata.ts:183-183 (schema)
Defines the input schema for the 'system-health-check' tool as an empty object (no parameters required).
```
inputSchema: z.object({}),
```
