Validation
- Use the Yavira download entry.
- Review SKILL.md after the package is downloaded.
- Confirm the extracted package contains the expected setup assets.
Install with your agent
Agent handoff
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
New install
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
Upgrade existing
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Smalltalk Skill
Execute Smalltalk code and browse live Squeak/Cuis images via MCP.
Prerequisites
Get the ClaudeSmalltalk repo first: git clone https://github.com/CorporateSmalltalkConsultingLtd/ClaudeSmalltalk.git This repo contains: MCP server code for Squeak (MCP-Server-Squeak.st) Setup documentation (SQUEAK-SETUP.md, CLAWDBOT-SETUP.md) This Clawdbot skill (clawdbot/)
Setup
Set up Squeak with MCP server β see SQUEAK-SETUP.md Configure Clawdbot β see CLAWDBOT-SETUP.md
Usage

Playground (Default)
Stock image, ephemeral. Changes are discarded when daemon stops. User says: "load Smalltalk skill" or "invoke Smalltalk" β no special flags. # Start playground daemon nohup python3 smalltalk-daemon.py start > /tmp/daemon.log 2>&1 &
Dev Mode
User supplies their own image/changes pair. Changes persist across sessions. User says: "load Smalltalk skill in dev mode with ~/MyProject.image" # Start dev daemon with custom image nohup python3 smalltalk-daemon.py start --dev --image ~/MyProject.image > /tmp/daemon.log 2>&1 & Dev mode sets SMALLTALK_DEV_MODE=1 so the MCP server keeps the .changes file (instead of redirecting to /dev/null). The supplied image must have a matching .changes file alongside it.
Common Commands
# Check status python3 smalltalk.py --daemon-status # Stop daemon python3 smalltalk-daemon.py stop # Restart in dev mode python3 smalltalk-daemon.py restart --dev --image ~/MyProject.image

Using with Claude Code (MCP mode)
When Claude Code has a live Smalltalk image connected via MCP, explain-method and audit-comment can use pre-fetched source code instead of requiring a running daemon. Use --source, --source-file, or --source-stdin to pass the method source directly: # Inline source (fetched via MCP, passed on command line) python3 smalltalk.py explain-method SmallInteger + --source "+ aNumber <primitive: 1> ^ super + aNumber" # Source from a file python3 smalltalk.py audit-comment Integer factorial --source-file /tmp/factorial.st # Source piped via stdin echo "printString ^ self printStringLimitedTo: 50000" | python3 smalltalk.py explain-method Object printString --source-stdin The three source flags are mutually exclusive. When none is provided, the daemon is used as before.
Generating SUnit Tests
The generate-sunit command uses an LLM to generate SUnit test cases for Smalltalk methods and files them directly into the running image: # Generate tests for a single method python3 smalltalk.py generate-sunit "String>>asUppercase" # Generate tests for multiple methods python3 smalltalk.py generate-sunit "Random>>next" "Random>>nextInt:" "Random>>seed:" # Generate tests for an entire class (all instance methods) python3 smalltalk.py generate-sunit "OrderedCollection" # Generate tests for class-side methods python3 smalltalk.py generate-sunit "Date class>>today" # Custom test class name python3 smalltalk.py generate-sunit "String>>asUppercase" --class-name MyStringTests # Overwrite existing test class python3 smalltalk.py generate-sunit "String>>asUppercase" --force # Run the generated tests python3 smalltalk.py evaluate "StringGeneratedTest buildSuite run printString" The generated TestCase uses standard SUnit assertions (assert:, assert:equals:, deny:, should:raise:) and is filed into a GeneratedSUnit-* category.
Notes
Requires xvfb for headless operation on Linux servers Uses Squeak 6.0 MCP server (GUI stays responsive if display available) saveImage intentionally excluded for safety MCPServer version 7+ required (v7 adds class-side method support) Playground mode: ephemeral, .changes β /dev/null Dev mode: persistent, .changes kept, requires --dev --image PATH
Category context
Agent frameworks, memory systems, reasoning layers, and model-native orchestration.
