Description
Modify Clawd, the Claude Code mascot. Use this skill when users want to customize Clawd's appearance in their Claude Code CLI, including changing colors (blue Clawd, green Clawd, holiday themes), adding features (arms, hats, accessories), or creating custom ASCII art variants. Triggers include "change Clawd color", "give Clawd arms", "customize the mascot", "modify Clawd", "make Clawd [color]", or any request to personalize the Claude Code terminal mascot.

Clawd Modifier
Customize the Claude Code mascot's appearance by modifying colors and ASCII art.
Quick Reference
CLI location: /opt/node22/lib/node_modules/@anthropic-ai/claude-code/cli.js
Clawd colors:
- Body:
rgb(215,119,87)/ansi:redBright - Background:
rgb(0,0,0)/ansi:black
Small Clawd (prompt):

Workflows
Change Clawd's Color
Use scripts/patch_color.py:
# List available colors
python scripts/patch_color.py --list
# Apply preset
python scripts/patch_color.py blue
# Custom RGB
python scripts/patch_color.py --rgb 100,200,150
# Restore original
python scripts/patch_color.py --restore
Add Arms or Modify Art
Use scripts/patch_art.py:
# List variants
python scripts/patch_art.py --list
# Add arms
python scripts/patch_art.py --variant with-arms
# Individual modifications
python scripts/patch_art.py --add-left-arm
python scripts/patch_art.py --add-right-arm
# Restore original
python scripts/patch_art.py --restore
Extract Current Clawd
Use scripts/extract_clawd.py to see current state:
python scripts/extract_clawd.py
Manual Modifications
For custom changes not covered by scripts, edit cli.js directly:
- Backup:
cp cli.js cli.js.bak - Find patterns with grep
- Use sed or text editor to replace
- Test by running
claude
Pattern examples:
# Find color definitions
grep -o 'clawd_body:"[^"]*"' cli.js | head -5
# Replace color
sed -i 's/rgb(215,119,87)/rgb(100,149,237)/g' cli.js

Notes
- Changes are overwritten by
npm update - Always create backups before modifying
- Test with
claude --versionafter changes - Some terminals have limited Unicode support
Usage Guidance
This skill does what it says (edits the Claude Code CLI mascot), but it modifies installed application files — including an option to patch compiled binaries — which is potentially dangerous. Before using: 1) Verify the skill's source and trustworthiness; avoid running unknown scripts as root. 2) Inspect the scripts yourself (they're included) and prefer patch_color.py / patch_art.py that edit cli.js over patch_binary.py unless you fully understand the binary format. 3) Always create and verify backups; test in an isolated VM/container or a non-production account. 4) Use the --dry-run flags where available and confirm the exact target path (do not rely on defaults). 5) Be aware npm updates will overwrite these changes; consider maintaining local patches or forking the package instead of in-place edits. If you are not comfortable with manual file and binary patching, do not install/run this skill.
Capability Analysis
Type: OpenClaw Skill
Name: clawd-modifier
Version: 1.0.0
This skill is classified as suspicious due to its use of high-risk capabilities, specifically the direct modification of system-level files and a compiled binary. The scripts (`patch_art.py`, `patch_color.py`) modify the `cli.js` file, and `patch_binary.py` performs byte-level patching on the `claude` executable. While the stated purpose is benign (customizing a mascot's appearance), these actions involve powerful system modification techniques that carry inherent risks, even with included safeguards like backups and dry-run options. There is no clear evidence of malicious intent such as data exfiltration or persistence.
Capability Assessment
Purpose & Capability
Name/description (modify Clawd appearance) aligns with the provided scripts and references: patch_color.py and patch_art.py edit cli.js to change colors and ASCII art, extract_clawd.py extracts the current art, and assets/references document the expected patterns and locations.
Instruction Scope
Runtime instructions explicitly tell the agent/user to locate and edit /opt/node22/lib/node_modules/@anthropic-ai/claude-code/cli.js (and provide grep/sed examples). That scope is appropriate for the stated purpose but broad: scripts read/write system-wide package locations and the SKILL.md encourages manual sed edits. The instructions do not attempt to exfiltrate data or call external endpoints, but they grant broad discretion to modify application code and instruct using shell commands that can be destructive if misapplied.
Install Mechanism
There is no install spec and all code to run is bundled in the skill (Python scripts and reference files). No remote downloads, package manager installs, or extracted archives are used, which reduces supply-chain risk. The script bundle will be executed on-host by the agent or user, so review before running is still required.
Credentials
The skill requests no credentials or environment variables, which is proportionate, but it accesses and modifies system paths (multiple candidate cli.js and binary locations under /opt, /usr/local, user home dirs). Modifying files in these locations typically requires elevated privileges and can affect the application's integrity and updates (the SKILL.md notes npm update will overwrite changes). The ability to edit compiled binaries (patch_binary.py) amplifies risk if search/replace patterns mismatch.
Persistence & Privilege
The scripts perform persistent, on-disk changes: they write backups and then overwrite cli.js or binaries. While the skill does not set always:true or change other skills' configs, binary/cli modifications are persistent across restarts and package updates and can break update integrity or introduce unexpected behavior. patch_binary.py carries particularly high persistence and privilege implications.
