## Which one, for what

### AutoIt (D)

Good for: An agent automating Windows desktop apps on one machine, and AutoItX lets C# or PowerShell code call the same functions.

Watch for: Closed source under a licence that forbids reverse engineering

### Robot Framework (BB)

Good for: Agents that write or run keyword-driven test and RPA suites across web, desktop and mobile through libraries.

Ahead on:
- Reliability, 95 against 59
- Schema & documentation, 86 against 52
- Agent ergonomics, 78 against 51
- Security & auth, 50 against 20
- Maintenance & community, 90 against 20
- Transparency & trust, 76 against 57

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card
- Open source

Watch for: Desktop and mobile control depend on separate libraries, such as AppiumLibrary and AutoItLibrary, maintained outside the core project

## Verdicts

**AutoIt.** An agent can run AutoIt scripts or single lines from the command line, or call AutoItX from C# or PowerShell, with each function's return values and `@error` codes documented. The source is closed, the last release was 7 September 2025, and scripts act with the full rights of the Windows user.

**Robot Framework.** A stable 7.5 release, passing unit and acceptance tests, JSON schemas for results and library docs, and an llms.txt make it a dependable base for agent-written automation. Desktop and mobile control come from separate community libraries, there is no official MCP server, and no security policy or security.txt was found.

## Before you call either

### AutoIt

1. Pass `/ErrorStdOut` so a fatal error reaches stdout instead of a dialog
2. Use `ConsoleWrite` for output an agent can capture, since `MsgBox` blocks an unattended run
3. Check `@error` after each call. Functions report failure there, not by raising
4. Install the official package from autoitscript.com. NuGet copies of AutoItX are third-party repackages

### Robot Framework

1. Install with `pip install robotframework` and check with `robot --version`. Add the library for the target app, such as AppiumLibrary, separately
2. Read the exit code. It is the number of failed tests or tasks up to 250, and 252, 253 or 255 mean bad input, a user stop or an internal error
3. Use `--dryrun` to validate a suite without running keywords, and `--rerunfailed output.xml` to repeat only failures
4. Convert results with `rebot --output output.json output.xml` for JSON that matches doc/schema/result.json
5. Keep secrets out of keyword arguments, because log.html records arguments unless keywords are removed with `--removekeywords`
