Analyze pasted Zigbee2MQTT, Home Assistant ZHA, or OpenThread logs for fault signatures.

When to use:

• Use this tool when diagnosing runtime error logs, adapter timeouts (SRSP ... after 6000ms), MAC/NWK/APS status codes (0x10, 0x11, 0xc7, 0xcd, 0xe1/225, 0xe9/233, 0xf0/240, 0xf1/241), interview failures (0xa7), or ZCL telemetry/genTime floods.

• Do NOT use for decoding raw hexadecimal MCU register words (decode_silicon_register), sizing network capacity (check_coordinator_capacity), or querying hardware benchmark tables (get_zerostack_benchmarks).

Behavior:

• Executes deterministically offline with zero network or serial I/O.

• Ranks detected faults by severity and root-cause priority (ZNP_SYS_RESET_IND > lockstep timeouts > memory/buffer exhaustion > RF delivery symptoms) and returns stock SDK root causes, immediate workarounds, and SMLIGHT ZeroStack (Release Zero (0.9.9-beta.1)) fixes.

Decode a hexadecimal MCU register or radio-core command status word into bitfields.

When to use:

• Use this tool when inspecting a TI SimpleLink F2 (CMD_IEEE_RX, CMD_IEEE_CSMA, RFC_DBELL, SRCMATCH, VIMS, PRCM, UART0_FR, UART0_RSR, UART0_CTL, IOCFG0..31, AON_PMCTL_RESETCTL), Silicon Labs EFR32 (EUSART0_IF, USART0_IF, USART0_STATUS, EMU_RSTCAUSE), or ARM Cortex-M4/M33 (SCB_CFSR 0xE000ED28, SCB_HFSR 0xE000ED2C) hex register/status value captured from SWD/JTAG, a crash dump, or telemetry.

• Do NOT use for parsing multi-line host application logs (analyze_zigbee_thread_log) or evaluating mesh node counts (check_coordinator_capacity).

Behavior:

• Executes deterministically offline with zero hardware or network I/O.

• Returns decoded bitfield flags, boolean healthy status, root-cause diagnosis, and links to silicon errata notes; raises ValueError on unsupported chip or register_or_addr identifiers or unparseable hex_value strings.

Calculate hardware SrcMatch slot utilization, pendAll threshold, and SRAM heap headroom.

When to use:

• Use this tool for capacity planning and topology sizing given (device_count, sleepy_zed_count, chip_family) to evaluate 32-slot RFC_RAM SrcMatch exhaustion, pendAll (FP=1) promotion when sleepy_zed_count > 32, indirect queue quota isolation, and SRAM headroom (88 KB / 144 KB / 256 KB).

• Do NOT use for parsing runtime logs (analyze_zigbee_thread_log), decoding register hex values (decode_silicon_register), or fetching DWT->CYCCNT latency benchmarks (get_zerostack_benchmarks).

Behavior:

• Executes deterministically offline; derives router_count = device_count - sleepy_zed_count.

• Raises ValueError if device_count < 0, sleepy_zed_count < 0, sleepy_zed_count > device_count, or chip_family is unrecognized.

Retrieve hardware-verified DWT->CYCCNT latency and fault-injection benchmarks by SKU.

When to use:

• Use this tool to query hardware specifications (CPU, Flash/SRAM, DIO10/DIO11 RTS/CTS wiring, supported baud rates) and cycle-accurate Part 1 execution latencies (TCLK lookup, NWK encrypt/decrypt, routed hop ceiling, O(1) allocator) plus Part 2 adversarial resilience metrics (3,255 MAC vectors, 22,959 brownout cut points, UART framing abuse, 50-router broadcast storms) for an SMLIGHT coordinator model or 'all'.

• Do NOT use for sizing a user's specific mesh node count (check_coordinator_capacity) or diagnosing pasted log text (analyze_zigbee_thread_log).

Behavior:

• Executes deterministically offline with zero network or hardware I/O.

• Raises ValueError if platform does not match a supported SMLIGHT SKU or 'all'.
