Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (9)

`calculate_battery_bank`	Calculate the recommended battery bank size based on daily energy consumption. Accounts for days of autonomy (how many days without charging) and depth of discharge. Returns required capacity, number of batteries, and wiring configuration.
`calculate_battery_config`	Determine how to arrange batteries in series and/or parallel to achieve a target voltage and capacity. Returns the number of batteries needed, the wiring configuration (e.g. 2S3P), and step-by-step wiring instructions.
`calculate_charging_time`	Estimate how long it takes to charge a battery bank from a given state of charge to a target level. Accounts for the bulk charging phase (constant current, up to ~80% SoC) and the slower absorption phase (tapering current, 80-100% SoC). Works for any charging source: solar, shore power, alternator.
`calculate_inverter_size`	Calculate the recommended inverter size for running AC loads from a DC battery system. Accounts for continuous power, startup surge power (motors typically surge 2-3x), and includes a 25% headroom for the continuous rating. Returns the recommended inverter wattage and the DC current draw at system voltage.
`calculate_power_budget`	Calculate total daily energy consumption from a list of electrical loads. Each load specifies its power draw, how many hours per day it runs, and quantity. Returns total daily energy (Wh and Ah), peak power draw, and average power. This is typically the first step in sizing a battery bank and solar system.
`calculate_solar_size`	Calculate the required solar panel wattage to cover daily energy consumption. Accounts for peak sun hours at the location and system efficiency losses (MPPT conversion, wiring, temperature derating). Returns required wattage and common panel configurations.
`calculate_wire_gauge`	Calculate the recommended wire gauge / cable cross-section for a DC circuit. Considers both ampacity (current carrying capacity) and voltage drop to recommend the optimal cable size. Also returns total resistance, power loss, and a fuse recommendation. Supports copper conductors from 0.75 mm² (18 AWG) to 240 mm² (300 MCM).
`generate_wiring_diagram`	Generate an electrical wiring diagram for campers, boats, or off-grid setups. Returns a complete schematic with batteries, chargers, protection components, and loads. Protection components (shunt, main switch, low-voltage cutoff) are auto-generated when both batteries and loads are provided.
`list_component_types`	List all available component types and example configurations for building wiring diagrams. Use this to understand what parameters are needed before calling generate_wiring_diagram.

Schemas: list_tools.
