YYLO Ninja
Jump Skill — Master orchestrator that routes YYLO workflow tasks to 7 specialized skills from the official YYLO repository.
Purpose
This skill acts as an intelligent router to the canonical YYLO skills library. Instead of manually searching for the right skill, describe your workflow task and this skill will:
- Identify the most relevant specialized skill(s)
- Load the full skill instructions on demand
- Execute the task with expert-level YYLO knowledge
Prerequisites
The skills drive the yy CLI (npm package @yylo/cli, Node.js 20.10+ and Git). Before executing a task:
- Verify
yy --helpworks; if not, install withnpm install --global '@yylo/cli@latest' yy ledgerandyy benchmarkdelegate to the separately installedyylo-ledger/yylo-benchmarkCLIs — Record namespaces must appear in the installedyy ledger --helpbefore an agent uses them- The four Ledger Record skills (wiki, workflow, artifact, ledger-tasks) are usable with standalone Ledger; the planning and execution skills rely on YYLO orchestration
- Inspect
COMMAND --helpbefore acting; if a namespace is absent, the installed version does not expose it — do not fall back to editing Ledger storage directly
Read operations (listing tasks, searching wiki Records, inspecting artifacts) are safe to run directly. Mutating operations (finishing tasks, landing merges, creating Records) change repository state — confirm with the user first, and never push, deploy, or mutate production without separate authority.

Task Management
| Skill | Path | Use When |
|---|---|---|
ledger-tasks-yylo | {{JUMP_SKILLS_DIR}}/repos/yylo-ninja/yylo-skills/skills/ledger-tasks-yylo/ | Operate the YYLO Ledger board: create, list, search, mark, update, archive tasks, manage dependencies and ordering |

Durable Records (YYLO Ledger)
| Skill | Path | Use When |
|---|---|---|
wiki-yylo | {{JUMP_SKILLS_DIR}}/repos/yylo-ninja/yylo-skills/skills/wiki-yylo/ | Durable project knowledge as wiki Records: search before creating, classify correctly, make revision-safe updates |
workflow-yylo | {{JUMP_SKILLS_DIR}}/repos/yylo-ninja/yylo-skills/skills/workflow-yylo/ | Create and maintain validated workflow Records, keeping storage, execution, and run evidence as separate boundaries |
artifact-yylo | {{JUMP_SKILLS_DIR}}/repos/yylo-ninja/yylo-skills/skills/artifact-yylo/ | Capture and retrieve durable artifact Records: intentional profiles, payload modes, provenance, retention, secret-safe evidence |
Autonomous Execution
| Skill | Path | Use When |
|---|---|---|
ralph-loop-yylo | {{JUMP_SKILLS_DIR}}/repos/yylo-ninja/yylo-skills/skills/ralph-loop-yylo/ | Execute exactly ONE explicitly assigned task through the Ralph loop to a validated queued commit — only on explicit user request |
Routing Logic
Intent
- Create / move / archive a task? →
ledger-tasks-yylo - Plan or register new work? →
plan-ledger-tasks-yylo(PDR first, then tasks) - "Understand this project first"? →
understand-project-yylo - Find or update project knowledge / docs? →
wiki-yylo - Define a repeatable validated workflow? →
workflow-yylo - Capture evidence / receipts / provenance? →
artifact-yylo - "Run the ralph loop on TASK_ID"? →
ralph-loop-yylo(explicit request only)
Task state
- Task not started / needs implementation →
understand-project-yylo→plan-ledger-tasks-yylo→ralph-loop-yylo - Task in flight, validation evidence needed →
artifact-yylo(report Records) +ledger-tasks-yylo(checkpoints) - Knowledge should outlive the session →
wiki-yylo - Merge-time →
ledger-tasks-yyloboard state + YYLO CLIyy merge status(the merge queue owns review)
Execution Pattern
1. Announce: "Routing to [skill-name]..."
2. Verify: yy CLI available (install @yylo/cli if not); Ledger namespaces present in yy ledger --help
3. Load: Read the SKILL.md from the path in the catalog
4. Execute: Follow the skill's instructions
5. Confirm: For any mutating operation (task finish, merge land, Record writes), confirm with the user before running it
6. Cite: Reference the skill in the response
Quick Reference
| Task | Route To |
|---|---|
| Create / list / search / archive Kanban tasks | ledger-tasks-yylo |
| Plan a feature (PDR + tasks) | plan-ledger-tasks-yylo |
| Inspect the codebase before changing it | understand-project-yylo |
| Find / update durable project docs | wiki-yylo |
| Define a validated workflow Record | workflow-yylo |
| Capture run evidence with provenance | artifact-yylo |

# YYLO Ninja
**Jump Skill** — Master orchestrator that routes YYLO workflow tasks to 7 specialized skills from the official YYLO repository.
## Purpose
This skill acts as an intelligent router to the canonical YYLO skills library. Instead of manually searching for the right skill, describe your workflow task and this skill will:
1. Identify the most relevant specialized skill(s)
2. Load the full skill instructions on demand
3. Execute the task with expert-level YYLO knowledge
## Prerequisites
The skills drive the **`yy` CLI** (npm package `@yylo/cli`, Node.js 20.10+ and Git). Before executing a task:
1. Verify `yy --help` works; if not, install with `npm install --global '@yylo/cli@latest'`
2. `yy ledger` and `yy benchmark` delegate to the separately installed `yylo-ledger` / `yylo-benchmark` CLIs — Record namespaces must appear in the installed `yy ledger --help` before an agent uses them
3. The four Ledger Record skills (wiki, workflow, artifact, ledger-tasks) are usable with standalone Ledger; the planning and execution skills rely on YYLO orchestration
4. Inspect `COMMAND --help` before acting; if a namespace is absent, the installed version does not expose it — do not fall back to editing Ledger storage directly
> **Read operations** (listing tasks, searching wiki Records, inspecting artifacts) are safe to run directly.
> **Mutating operations** (finishing tasks, landing merges, creating Records) change repository state — confirm with the user first, and never push, deploy, or mutate production without separate authority.

## Routing Logic
### Intent
1. **Create / move / archive a task?** → `ledger-tasks-yylo`
2. **Plan or register new work?** → `plan-ledger-tasks-yylo` (PDR first, then tasks)
3. **"Understand this project first"?** → `understand-project-yylo`
4. **Find or update project knowledge / docs?** → `wiki-yylo`
5. **Define a repeatable validated workflow?** → `workflow-yylo`

7. **"Run the ralph loop on TASK_ID"?** → `ralph-loop-yylo` (explicit request only)
### Task state
- Task not started / needs implementation → `understand-project-yylo` → `plan-ledger-tasks-yylo` → `ralph-loop-yylo`
- Task in flight, validation evidence needed → `artifact-yylo` (report Records) + `ledger-tasks-yylo` (checkpoints)
- Knowledge should outlive the session → `wiki-yylo`
- Merge-time → `ledger-tasks-yylo` board state + YYLO CLI `yy merge status` (the merge queue owns review)
