What it does
Make Tweakable is an agent skill from bluzir/claude-code-design. Add an in-artifact floating Tweaks panel that lets the user adjust colors, fonts, spacing, layout variants live in the preview. Persists via claude-pipe pattern (pending.yaml + apply-tweaks skill).
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design. The repository describes itself as: Claude Design reproduced for Claude Code — HTML decks, prototypes, design systems, animated videos via skills + starters + Chrome DevTools MCP.
When your agent uses it
- Frontend & Design work in your project
Example prompts
- “/make-tweakable”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash(mkdir:*), mcp__chrome-devtools__*
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Decide keys
- Refactor HTML to use --tweak- vars
- Inject Tweaks panel
- Session state file
- Verify
What it can do on your machine
Read from SKILL.md and the folder at commit ce68c84. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGlobGrepBash(mkdir:*)mcp__chrome-devtools__*
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are html and css).
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
Make Tweakable loads about 2.2k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 272 words of instructions outside code blocks.
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); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 272 words (~2,188 tokens).
“Inject a floating Tweaks panel into an existing HTML artifact. Panel lives in-artifact (no iframe), uses File System Access API for persistence (with copy-paste fallback).”
