Ecosystem package · v2.0.0

Give agents a reliable way to do the work.

YYLO Skills are independently versioned, reusable procedures for operating YYLO and Ledger. They support the three product layers without becoming a fourth layer or copying product behavior into prompts.

Install Skills Review source

Two explicit install paths

Use the open Skills CLI today; use YYLO when published.

The direct open-standard path is available now and can install the repository or one slug. YYLO source candidate 0.2.3-rc.1 adds a validated all-seven installer, but it is not presented as current installable behavior until that CLI version is published.

npx skills add yylo-dev/yylo-skills
npx skills add yylo-dev/yylo-skills --skill wiki-yylo

yy skills install
yy skills install --version 2.0.0
yy skills status

The current Ledger source also contains a targeted four-skill installer. It follows the same publication boundary. Installation and update are explicit network operations; ordinary status and product commands remain offline.

Canonical catalog

Seven goals, grouped by intent.

Choose a goal to understand when the skill helps. The complete instruction remains in the versioned source repository.

Ledger Records

Skills for working with YYLO Ledger as the source of truth.

ledger-tasks-yylo

Comprehensive guide for using YYLO Ledger task management. Covers all commands (create, list, search, get, mark, update, archive, deps, ready, order, merge), dependency management, best practices, and workflow patterns. Use when you need to interact with the YYLO Ledger board.

wiki-yylo

Use YYLO Ledger wiki Records as durable project knowledge. Search before creating, classify information correctly, and make revision-safe Markdown updates without editing Ledger storage directly.

Understand this skill →

workflow-yylo

Create and maintain validated YYLO Ledger workflow Records while keeping storage, execution, and run evidence as separate explicit boundaries.

Understand this skill →

artifact-yylo

Capture and retrieve durable YYLO Ledger artifact Records with intentional profiles, payload modes, provenance, retention, and secret-safe immutable evidence.

Understand this skill →

Planning

Skills for understanding projects and planning Ledger work.

understand-project-yylo

Inspect the current product architecture, dependencies, and validation loops before planning or implementing a requested change.

Understand this skill →

plan-ledger-tasks-yylo

Create a concise Product Development Requirement and one or more implementation-sized YYLO Ledger tasks when the user explicitly asks to plan or register work.

Understand this skill →

Execution

Skills for bounded task-driven delivery.

ralph-loop-yylo

Execute exactly one explicitly assigned YYLO Ledger task through the Ralph loop to a validated queued commit. Use only when the user explicitly requests ralph-loop-yylo.

Safety boundary

Review skills like code.

A skill can steer an agent and may reference executable procedures. Review the canonical version before installation. YYLO preserves customized and unrelated local skills unless an explicit, bounded replacement is authorized.
