$ npx skills add rj11io/11ai --full-depthHow it works
What is a skill?
A skill is a folder of markdown instructions your coding agent reads before doing a job. Each one is led by a SKILL.md file: a name, a description of when to use it, and a detailed, battle-tested playbook. No runtime, no lock-in — just knowledge your agent can follow.
- 1
Install the collection
Run
npx skills add rj11io/11ai --full-depthand pick the skills you want. Works with any agent that supports the skills format. - 2
Ask your agent by name
Say “Use 11ai-ai-chat-stack to add a chat surface to this app” — the agent loads the matching playbook.
- 3
The agent follows the playbook
It applies the architecture, patterns, and checklists from the skill instead of improvising from scratch.

name: 11ai-pragmatic
description: Speak in the short register, always extremely pragmatic and objective: extremely concise lines, grammar sacrificed for concision, lists over paragraphs, no em dashes, an example or snippet for every claim, sources cited. Four working modes on top: a fix beside every problem found when reviewing, no file changes while planning until the action plan is approved, a pointer to where changes landed when implementing, and a copyable conventional commit message with scope after any repo work. Use when the user asks for terse, punchy, or no-fluff replies, sets a brevity rule for the session, or says an answer reads long-winded, padded, or hedged.

Explore pluginConcept spotlight
Ledger + Conductor + Routine
The agent-automation plugin is built on one pattern for autonomous agents that ship real, verifiable work on a schedule. Three pieces, one loop.
Ledger
One JSON file as the single source of truth: configuration plus work items, each with a status and a milestone plan. Read first, write last.
Conductor
One spec the agent re-reads every run: the state machine, the per-tick algorithm, a depth bar, a review rule, and a quality gate.
Routine
A scheduler that fires a provider-agnostic headless agent CLI with a thin trigger prompt and a single-instance lock.
Each run (“tick”) is a pure function
(ledger, conductor)→one milestone→new ledger
A milestone is a complete vertical slice — failing checks, implementation, one evidence-backed review, and a quality gate — shipped in a single run. Green typecheck and lint alone never finish an item; automated probes must prove a stranger could actually use the output.

One command installs the whole collection. Everything is plain markdown, versioned on npm, and open source on GitHub.
