first-tree

name	first-tree
description	Entry point for the first-tree toolkit — Context Tree methodology, the `first-tree` CLI, and routing into the `tree`, `breeze`, and `gardener` product skills. Use whenever a task touches strategic choices, cross-domain relationships, workspace-wide context, Context Tree onboarding, or any `first-tree` CLI command.

First Tree

This is the entry-point skill for the first-tree toolkit. It teaches:

1. What a Context Tree is — the methodology shared across the toolkit
2. Which product skill to load for the specific task in front of you
3. How to get the first-tree CLI installed and up to date
4. How skills are managed on the machine you are working on

If your task needs product-specific operational detail (running commands, inspecting state, fixing things), follow the routing below to the right product skill and load that in addition to this one.

What Is Context Tree

A Context Tree is a git-native, file-based knowledge base that captures why decisions were made and how domains relate, not how things are executed. Each domain is a directory containing a NODE.md. Each leaf decision is a markdown file with frontmatter declaring title, owners, and optional soft_links to related nodes.

Read references/whitepaper.md for the product vision and methodology, and references/principles.md for the four core principles you must follow when reading or writing nodes.

When To Use This Skill

Trigger this skill when you are asked to:

• Read or update any NODE.md or leaf node
• Make a decision that affects multiple domains or repos
• Check ownership before editing a node
• Onboard a new repo, shared tree, or workspace root
• Run any first-tree CLI command
• Investigate why a particular decision was made
• Install, update, or inspect the first-tree skills on this machine

Do not use this skill for routine code edits that do not touch decisions, constraints, ownership, or cross-domain relationships.

Three Products Under One CLI

first-tree is an umbrella CLI over three products. Each product has its own operational skill — load the one that matches your task:

Product	Skill to load	Use when you need to…
tree	tree	Onboard (init) / inspect / publish / verify / upgrade a Context Tree repo, or reach for the lower-level primitives (bind, bootstrap, integrate, workspace sync)
breeze	breeze	Run or inspect the breeze daemon: install, start/stop/status, watch, one-shot poll, diagnose
gardener	gardener	Install the push-mode workflow, run the pull-mode daemon, or invoke the agent primitives (sync, comment, respond) from CI or breeze

Each product's --help splits its commands into Primary (start here) and Advanced / Agent (primitives invoked by the daemon, breeze dispatch, or CI). Humans should normally only need the primary set — load the product skill for the full map.

If you do not know which product you need, start here, skim the table above, and load whichever skill looks like the closest match. Loading more than one is fine.

The CLI also exposes one maintenance namespace: first-tree skill .... That namespace is not a fourth product — it is the toolkit surface for inspecting and repairing the four shipped skills.

Before Every Task

1. Read the root NODE.md.
2. Read the NODE.md of every relevant domain.
3. Follow soft_links.
4. Read the leaf nodes that match your task.

Skipping this step produces decisions that conflict with existing ones.

During The Task

• Decide in the tree, execute in source systems.
• Keep execution detail out of the tree.
• Respect ownership. See references/ownership-and-naming.md.

After Every Task

Always ask: does the tree need updating?

• Did the task change decisions, constraints, ownership, or workspace-level relationships?
• Did you discover something the tree failed to capture?
• Did you find outdated tree content?

Installing And Updating The CLI

Recommended invocation — no install step needed, always runs the latest published version:

npx first-tree <namespace> <command>

For automation, hooks, and CI templates, prefer the more explicit form:

npx -p first-tree first-tree <namespace> <command>

The CLI auto-checks for updates on every invocation. Pass --skip-version-check to suppress the check for latency-sensitive callers like SessionStart hooks.

Managing Skills On This Machine

The first-tree toolkit ships four skills: this one (first-tree) plus one per product (tree, breeze, gardener). They live at:

.agents/skills/first-tree/
.agents/skills/tree/
.agents/skills/breeze/
.agents/skills/gardener/

Each is also mirrored at .claude/skills/<name>/ via a symlink so both Claude Code and other agent runtimes discover them.

To install or refresh the shipped skill payloads in the current repo:

npx first-tree skill install
npx first-tree skill upgrade

These commands rewrite the installed skill copies to match the skills bundled inside the package. Safe to re-run; idempotent.

Use npx first-tree tree upgrade when you want the broader source/workspace integration or tree metadata refreshed too.

To inspect or repair the installed skills directly:

npx first-tree skill list     # show all four skills + versions
npx first-tree skill doctor   # diagnose install health; exits non-zero on problems
npx first-tree skill link     # repair .claude/skills/* symlinks

Ownership And Editing

• Every directory has a NODE.md declaring owners in its frontmatter.
• Empty owners: [] inherits from the parent.
• owners: [*] means anyone may edit.
• Otherwise only the listed owners may approve changes.

See references/ownership-and-naming.md.

Files In This Skill

• SKILL.md — this file
• VERSION — installed skill payload version
• references/whitepaper.md — First Tree white paper: Agent Team methodology, principles, and vision
• references/principles.md — four core principles with examples
• references/ownership-and-naming.md — node naming and ownership model
• references/onboarding.md — onboarding narrative for repos, shared trees, and workspaces
• references/source-workspace-installation.md — source/workspace binding contract

• references/workflow-mode.md — agent-driven install guide for the gardener push-mode sync workflow (replaces the gardener service with a .github/workflows/first-tree-sync.yml in the codebase)

Everything else lives in the first-tree npm package and is invoked via the CLI.
