What it does

Keil is an agent skill from Tansuo2021/ADtoKeil. Keil MDK/uVision build skill for embedded projects. Use when the user mentions Keil, MDK, uVision, UV4, C51, 8051, target enumeration, compile, build, rebuild, clean, firmware artifact paths, HEX output, or flash/download through a Keil project. Provides scripts to scan .uvproj/.uvprojx/.uvmpw projects, list Targets, run build/rebuild/clean/flash, parse logs, and return reusable artifact paths.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `README.md`, `config.example.json` and `references/compiler-notes.md`).

The licence is GPL-3.0.

Requirements

Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 56ab07d. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Keil loads about 1.2k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 455 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~101
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

name: keil
description: Keil MDK/uVision build skill for embedded projects. Use when the user mentions Keil, MDK, uVision, UV4, C51, 8051, target enumeration, compile, build, rebuild, clean, firmware artifact paths, HEX output, or flash/download through a Keil project. Provides scripts to scan .uvproj/.uvprojx/.uvmpw projects, list Targets, run build/rebuild/clean/flash, parse logs, and return reusable artifact paths.

Keil MDK / C51 Build

Use this skill for Keil/uVision projects, including 8051/C51 projects and MDK projects. Prefer the bundled scripts instead of manually invoking UV4.exe.

Capabilities

Scan a workspace for .uvproj, .uvprojx, and .uvmpw projects.
Enumerate project Targets.
Create or update a real project file when the user asks to develop firmware and no suitable project exists; prefer a vendor demo project as a template for C51 devices.
Run build, rebuild, clean, or compatible flash.
Parse the build log and return errors, warnings, HEX/AXF output paths, and metrics.
Persist the last successful build in .embeddedskills/state.json for workflow reuse.

Configuration

Environment-level config is stored in this skill's config.json:

json

{
  "uv4_exe": "C:\\Keil_v5\\UV4\\UV4.exe",
  "operation_mode": 1
}

Workspace-level config lives in .embeddedskills/config.json:

json

{
  "keil": {
    "uv4_exe": "D:/Keil_v5/UV4/UV4.exe",
    "project": "path/to/project.uvproj",
    "target": "Target 1",
    "log_dir": ".embeddedskills/build"
  }
}

Parameter priority: CLI arguments > workspace config > skill config > .embeddedskills/state.json > scan result.

Commands

Scan projects:

powershell

python <skill_dir>\scripts\keil_project.py scan --root <workspace> --json

List Targets:

powershell

python <skill_dir>\scripts\keil_project.py targets --project <project> --json

Build:

powershell

python <skill_dir>\scripts\keil_build.py build `
  --project <project> `
  --target <target> `
  --workspace <workspace> `
  --json

Rebuild:

powershell

python <skill_dir>\scripts\keil_build.py rebuild `
  --project <project> `
  --target <target> `
  --workspace <workspace> `
  --json

Clean:

powershell

python <skill_dir>\scripts\keil_build.py clean `
  --project <project> `
  --target <target> `
  --workspace <workspace> `
  --json

Rules

If multiple plausible projects or Targets exist, list candidates instead of guessing.
Do not edit .uvproj, .uvprojx, .uvopt, or .uvoptx unless the user explicitly asks. If the user asks for firmware development/buildable embedded software and no project exists, treat creating a .uvproj/.uvprojx as part of the deliverable.
Do not run clean implicitly before build unless the user asks for rebuild or --clean-first.
After a successful build, report the project, target, log file, errors/warnings, and HEX/AXF paths.
Treat flash as a compatibility entry. Prefer a dedicated J-Link/OpenOCD/probe workflow when available.
For C51 projects, inspect the build log and map file when debugging interrupt vectors, missing source files, memory model, or startup issues.
For vendor C51 libraries such as SinOne TKDriver, ensure the active project tree visibly includes the driver folder, headers/config files, .C files, and all required .LIB files. If a manual says to copy/export TKDriver into the target project, do not leave project paths pointing only to ..\TKDriver.

C51 Review

For 8051/C51 correctness problems, use the embedded firmware skill reference keil-c51-project-review.md if available. Check:

Correct Target and HEX are being built/flashed.
Startup file and interrupt vectors match the MCU.
Vendor .C or library files are included in the Keil project.
Vendor folder location matches the product project structure, especially for exported touch libraries.
Code Option / clock settings match firmware constants.
Memory model, reentrancy, and interrupt function declarations are compatible with C51.

C51 Project Creation Checklist

When creating a C51 .uvproj:

Reuse a matching vendor demo .uvproj and STARTUP.A51 when available.
Set the target name, output directory/name, HEX generation, include paths, and device clock.
Use LX51 and Large memory model when vendor libraries require it.
Put vendor driver folders such as TKDriver inside the target project directory when the manual says to migrate the folder there.
Add visible groups for Startup, App, BSP, Drivers, and vendor libraries.
Build/rebuild with keil_build.py and inspect the log/map to confirm the files used are the intended in-project files.

Can I use Keil in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Tansuo2021/ADtoKeil --skill keil -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/keil, .gemini/skills/keil, .github/skills/keil and .opencode/skills/keil in your project.

What does Keil need to run?

Going by SKILL.md and its folder, Keil needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.

Does Keil access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Keil safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Keil use?

Keil is published under the GPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Keil use?

About 1.2k tokens (SKILL.md is roughly 4.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 369 tokens, read only when the agent opens those files.

What are the alternatives to Keil?

Skills that share tags, products or a category with Keil: Embeddings (ruvnet/ruflo, 74k stars), Embedding Strategies (wshobson/agents, 40k stars), Embeddings via 9Router (decolua/9router, 30k stars) and Embeddings (alsk1992/CloddsBot, 2.9k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
