This file only covers how this starter wires Elements into Eleventy with Lit SSR. For component APIs, template validation, and project setup commands, use the Elements CLI/MCP documentation instead.
Where files are headingNew AGENTS.md files have more rules about keeping secrets out of the code, and fewer about code style.
Of the AGENTS.md files we read, the 31,774 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.
In this repository46 other files it gives its agents.

The file
We split this AGENTS.md into the rules it gives an agent
6 rules. About 0 are common, 1 is distinctive, and 5 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
5
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 8
Keep mode: 'worker' for SSR isolation unless the build requirement changes.
- Very specific: line 10
Use metadata to generate broad component entrypoint lists only for SSR demos that intentionally exercise many Elements.
- Very specific: line 14
Import @lit-labs/ssr-client/lit-element-hydrate-support.js in the client module script before importing client-side define.js modules.
- Distinctive: line 19
Keep raw generated examples filtered away from components that are not SSR-safe for this starter.
- Very specific: line 20
If transforming example templates, keep the transforms local and explicit in src/index.11ty.js.
- Very specific: line 24
Run pnpm run build in projects/starters/eleventy-ssr after SSR config, metadata filtering, or template changes.
≈ “Common” is an estimate: at least 1 in 5 of the 40,246 AGENTS.md files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Elements Eleventy SSR Starter
This file only covers how this starter wires Elements into Eleventy with Lit SSR. For component APIs, template validation, and project setup commands, use the Elements CLI/MCP documentation instead.
Integration Points
- Configure Lit SSR in
eleventy.config.jsthrough@lit-labs/eleventy-plugin-lit. - Keep
mode: 'worker'for SSR isolation unless the build requirement changes. - Provide server-renderable Elements through
componentModules; include@nvidia-elements/core/dist/icon/server.jsbefore componentdefine.jsentrypoints when icons can render server-side. - Use metadata to generate broad component entrypoint lists only for SSR demos that intentionally exercise many Elements.
Hydration
- Import
@lit-labs/ssr-client/lit-element-hydrate-support.jsin the client module script before importing client-sidedefine.jsmodules. - Match server
componentModulesand clientdefine.jsimports for components rendered in the HTML.
Template Constraints
- Keep raw generated examples filtered away from components that are not SSR-safe for this starter.
- If transforming example templates, keep the transforms local and explicit in
src/index.11ty.js.
Verification
- Run
pnpm run buildinprojects/starters/eleventy-ssrafter SSR config, metadata filtering, or template changes.

Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
