embedded-workbench plugin

Architecture planning, design packages, work breakdown, module ownership, state models, recovery paths, cross-module coordination.

Design document reviewer — verifies every claim against codebase facts, checks mechanism feasibility, finds root causes of errors, and delivers structured findings by severity.

Concrete implementation, targeted code edit, focused investigation, test run, build run, narrow module task, delegated coding slice.

Code review, quality gates, implementation review, risk check, test coverage check, coordination between plan and execution, bug regression review.

Use when writing, reviewing, or refactoring C/C++ code, especially on 32-bit ARM embedded targets. NOT for formatting-only changes, simple file reads, non-embedded C/C++ (desktop/server), or C#/Java despite the 'C' in the name.

Use when debugging embedded firmware issues — analyzing crash logs, investigating state machine lockups, tracing sensor/signal anomalies, or performing structured root-cause analysis after a crash has been located. For fault-register and stack-frame triage, load hardfault-triage first.

Use when writing or reviewing embedded C firmware, FreeRTOS tasks, ISR handlers, NVM/flash storage, or sensor driver state machines. NOT for documentation-only RTOS references, conceptual RTOS discussions, or bare-metal projects without an RTOS or sensor subsystem.

Use when starting any non-trivial coding task — loads risk-proportional workflows, engineering policies, and principles for embedded C/C++ firmware development. NOT for trivial single-line fixes, formatting-only changes, or read-only queries.

Use when reviewing design documents, architecture specs, technical proposals, or plans that make claims about API names, file paths, enum values, counts, or mechanism feasibility — a lightweight claim-by-claim check against the codebase with evidence. Built into embedded-workbench as the fallback when the full dsh-model-everything plugin (or its predecessor logicprobe) is not installed. NOT for state machines, protocol/retry logic, or 'always'/'never' behavioral claims that need executable model verification — those require dsh-model-everything (or logicprobe).

Use when triaging processor exception crashes — HardFault, MemManage, BusFault, UsageFault, data/prefetch abort, illegal instruction, or watchdog timeout. Covers fault-register interpretation, stack-frame extraction, PC-to-source resolution, and root-cause classification.

Use when building, flashing, or packaging firmware with Keil MDK (UV4 CLI, ARMCLANG), analyzing .map files for ROM/RAM optimization and memory budget, or diagnosing Keil-specific build failures. NOT for non-Keil build systems (Makefile, CMake, IAR, GCC-only). For crash triage see hardfault-triage.

Use when reviewing or fixing async protocols, retries, ACK/NACK handling, pending flags, timeout logic, or state-machine lockups in embedded firmware. NOT for generic network protocol design (TCP/HTTP/MQTT) unless targeting embedded firmware stack.
