Claude Code skills for building apps on CARLOS — Cost-efficient, Available, Replicated, Lightweight, Open, Secure — the application architecture described at carlosframework.com.
Two paths, one family:
- getting-started — the recipe:
empty directory to a live URL on the hosted platform
(carloku.com), every decision pre-made — rastrillo,
server-rendered HTML,
carlos deploy. For a first app with minimum further guidance. - building-carlos-apps — the menu: the family's principles, the platform member surface, the rastrillo recipe, and the four decision axes — trust model (full, partial, or server-side, with each source app's recorded reasoning), app shape (server-rendered vs client-owned, "HTML-first or more like Woodstar"), hosting (hosted, your own boxes, or self-hosting the platform), and identity.
Plus delegate — the operator's shorthand for decomposing a workload across capability-tiered subagents.
As a Claude Code plugin (recommended):
/plugin marketplace add carlosframework/skills
/plugin install carlos@carlos
The skills are then available as carlos:getting-started,
carlos:building-carlos-apps, and carlos:delegate.
Or plainly: copy a skill's directory into your app repo's
.claude/skills/ (or ~/.claude/skills/ for all projects). Each is a
handful of Markdown files; nothing else is required.
Or with no install at all: the platform-facing skills are published for
agent discovery at
carlosframework.com/.well-known/agent-skills/index.json,
per the Agent Skills Discovery
draft — an
index of name, description, url and sha256 digest per skill, with each
SKILL.md (and its references/) served beside it. delegate is
plugin-only on purpose: it is operator tooling, not knowledge about
CARLOS.
The website repo vendors those files from here (hack/sync-skills.mjs
in carlosframework/website, byte-for-byte — the digests pin the served
bytes to this repo's). When a published skill changes here, re-sync
and ship the website in the same batch, or the served copy drifts
behind the plugin.
Distilled July 2026 from the prompt histories, repo instruction files and
code of the five source applications plus the deliberate adopters; refreshed
August 2026 for the platform era — the carlos CLI, Carloku hosting,
rastrillo v0.5.0, and the decisions recorded by Keymail, Kass, Woodstar,
and Tito along the way. Contains no secrets, hostnames of
boxes, account ids, or private links; verified with baseline and
retrieval tests on fresh agents before publishing. The values layer
underneath is the eleven factors.
