keil-mdk-build SKILL.md skillA

keil-mdk-build from amethystluna/embedded-workbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add amethystluna/embedded-workbench/keil-mdk-build@git:20261009.b70e357

Pins git:20261009.b70e357 in mdr.lock. Pin the fingerprint instead.

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.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

<HARD-GATE>
This is a domain implementation skill. If you are planning, designing, or entering plan mode — load `Skill("embedded-workbench")` first to activate the workflow gates (Plan Verification Gate, Approval Gate, Closure Gate). Domain skills carry implementation guidance, not workflow enforcement.
</HARD-GATE>

# Keil MDK Build

Patterns for building embedded firmware with Keil MDK. Covers both ARM Compiler 5 (armcc) and ARM Compiler 6 (armclang).

## UV4 CLI Build (Authoritative)

UV4.exe batch mode is the canonical build path. A CI reimplementation is possible but may miss include paths.

```powershell
<Keil>\UV4\UV4.exe -b project.uvprojx -t TargetName -j0 -o <log_path>
```

Replace `<Keil>` with the Keil install root. Auto-discover by checking common locations or ask the user when unknown.

**Flags**:

| Flag | Meaning |
| ---- | ------- |
| `-b` | Batch mode (no GUI) |
| `-t <target>` | Target name within the multi-target project |
| `-j0` | Auto-parallelism (use all cores) |
| `-o <path>` | Log output file |

**Exit codes**:

| Code | Meaning |
| :--: | ------- |
| 0 | Success (no errors, no warnings) |
| 1 | Warnings but no errors |
| 2 | Errors |

How to install

The exact contents, by fingerprint
mdr add amethystluna/embedded-workbench/keil-mdk-build@sha256:af75973964f11f1d

The line at the top of this page pins the label git:20261009.b70e357, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
