- Adding a Preline UI component, such as an accordion, to an HTML page
- SKILL.md covers Intent, Defaults, Decision: Component vs Block and Clarifying Vague Requests, plus 7 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
The skill connects the agent to the Preline MCP server, which exposes 6 tools that return HTML, CSS and JavaScript ready to insert. It separates components from blocks, which are ready-made page sections: a request that says component follows the component workflow, one that says block or example follows the block workflow, and an ambiguous one leans toward blocks because they give more complete results.
The working rules are strict. The agent never guesses slugs and finds them through components_list or blocks_categories, retrieves and integrates one item at a time, and reads the target file before inserting anything. For abstract requests such as a pricing page, or when several candidates fit equally well, it asks you to choose, in English unless you write in another language. Reference files in the folder cover a catalog map, composite layouts and the MCP tools.
When your agent uses it
- Adding a Preline UI component, such as an accordion, to an HTML page
- Dropping a ready-made Preline block like a hero section into a site
- Building a starter page out of Preline blocks
Example prompts
- “/preline add a basic accordion to index.html”
- “Use Preline to put the SaaS hero with tabs at the top of landing.html.”
- “I need a pricing section for my page. Show me the Preline options.”
Requirements
- The Preline MCP server connected to your agent
- An HTML file to insert the markup into
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Ask which category fits. Call blocks_categories() and present the relevant mainSection / subSection / category paths with their titles and…
- Try to resolve in one round. If the user's reply both names a category and describes the item distinctively enough to identify a single…
- Otherwise, ask which block fits best. Call blocks_in_category({ mainSection, subSection, category }), list the block titles + descriptions…
- Fetch and integrate the chosen block with single_block.
What it can do on your machine
Read from SKILL.md and the folder at commit 05ca599. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Preline UI Components via MCP loads about 2.9k tokens when it runs, and up to ~7.7k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 1,478 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,478 words (~2,930 tokens).
“Use this skill to integrate Preline UI components and blocks into HTML files via the Preline MCP server. The server exposes 6 tools that return integration-ready HTML, CSS, and JS.”
