Use when working on anything TRMNL — building plugins, writing or editing markup, designing layouts using the TRMNL CSS framework, calling the TRMNL MCP server (mcp__trmnl__*), or any task that mentions "trmnl", "ePaper display", "e-ink display", "trmnl.com", "TRMNL plugin", "Liquid markup", "image-dither", "title_bar", or screen sizes 800x480 / 800x240 / 400x480 / 400x240. References embed the production prompts TRMNL's external MCP server ships — agent rules, the full design system template…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# TRMNL

Everything you need to work on TRMNL. The references in this skill are **verbatim copies** of the prompts TRMNL's own production AI assistant reads.

## Read first, in this order

| # | Reference | What it covers | Lines |
|---|---|---|---|
| 1 | [`references/agent_prompt.md`](references/agent_prompt.md) | Core rules: data-first hard gate, mandatory workflows, view dimensions, layout system, image dithering, no-custom-styles, no-emojis, common mistakes. **This is also what TRMNL's MCP server ships as the connection-level instructions to every external client.** | 427 |
| 2 | [`references/template_guide.md`](references/template_guide.md) | THE design system reference — every framework class, layout pattern, chart code, item component, custom-fields YAML schema. Bundled here so non-MCP users can read it offline; MCP-connected users can also fetch it via the design-system template-guide tool. | 2710 |
| 3 | [`references/framework_v3_guide.md`](references/framework_v3_guide.md) | v3 supplement: chromatic palette, CSS variables, label variants. v3.0.3+ specific. | 230 |

How to install

The exact contents, by fingerprint
mdr add usetrmnl/trmnl-agent-skills/trmnl@sha256:c6e1beb85709f93d

The line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
