ynh-guide

add-vendor-adapter

Scaffold a brand-new ynh vendor adapter end-to-end (a new AI CLI harness like GitHub Copilot CLI, Gemini CLI, etc.). Use when onboarding a vendor that has no adapter yet — as opposed to vendor-adapters, which maintains adapters that already exist against evolving vendor specs.

add-ynd-command

Add a new command to the ynd developer CLI end to end — dispatch, flag parsing, output formats, tests and docs. Use when adding a ynd subcommand, the sibling of add-vendor-adapter for the other half of the product.

Code & Development Listed

capability-bump

Change the JSON shape of a ynh command safely — decide whether it bumps CapabilitiesVersion, then update the schema, goldens and docs together. Use when adding, removing or changing any field in a --format json response.

ynh-dev

Development workflow for the ynh codebase. Build, test, lint, and format in the right order.

ynd-compress

Workflow for compressing prompt and instruction files using LLM-powered techniques, with backup management and restore.

Testing & QA Listed

ynd-inspect

Guided walkthrough for using ynd inspect to bootstrap a project's AI skills and agents from its codebase signals.

ynh-adopt

Bring an existing AI setup — a .claude folder, .cursorrules, a grown CLAUDE.md — under ynh without losing it. Use when someone already has assistant config and wants to adopt ynh, rather than starting a harness from scratch.

ynh-compose

Compose harnesses from other harnesses — includes, delegates, profiles, focuses and fork. Use when someone has one working harness and wants to reuse parts of it, share it, or vary it per situation rather than copying folders around.

ynh-create-harness

Interactive wizard to create a ynh harness from scratch. Walks through naming, vendor selection, artifact scaffolding, and installation.

ynh-sensors

Choose, declare and calibrate the sensors a project needs, then gate on them with ynh check. Use when a harness has no sensors, when ynh check reports nothing useful, or when setting up an agent loop that needs something to converge against.

ynh-team-setup

Guide graduation from a personal harness to a team setup with delegation. Creates a team harness that delegates to personal harnesses.

ynh-troubleshoot

Diagnose a ynh setup that is not working — a harness that will not install, a launcher that is not found, a vendor that cannot see the skills, instructions that are not applied, or a check that gates for no visible reason. Use when something is broken and it is not obvious why.
