Your First Session

A step-by-step walkthrough from install to parallel fan-out. Follow along in your terminal.

Try this:

mkdir my-app && cd my-app && git init
squad init

Then tell your team what you’re building.

1. Install Squad

Start with a git repo — new or existing:

mkdir my-app && cd my-app
git init
squad init

You’ll see:

✅ Squad installed.
   .github/agents/squad.agent.md — coordinator agent
   .squad/templates/ — 11 template files
Open GitHub Copilot and select Squad from the agent list.

2. Open Copilot — Your Team Forms

Start the Copilot CLI:

copilot

Select Squad from the /agent list (CLI) or /agents (VS Code). Squad greets you by name:

Hey Brady, what are you building?

Describe your project:

> I'm building a recipe sharing app with React and Node.js. Users can
> post recipes, search by ingredient, and save favorites.

Squad proposes a team. The coordinator analyzes your description and suggests specialists:

Here's your team:
🏗️  Hicks    — Lead          Scope, decisions, code review
⚛️  Ripley   — Frontend Dev  React, UI, components
🔧  Dallas   — Backend Dev   Node.js, APIs, database
🧪  Lambert  — Tester        Tests, quality, edge cases
📋  Scribe   — (silent)      Memory, decisions, session logs
**Scribe** and **Ralph** are always on every roster — you don't manage them.
Look right? Say yes, add someone, or change a role.
(Or just give me a task to start!)

3. Confirm and Give Your First Task

Say “yes” or skip straight to a task (which is implicit confirmation):

> Yes. Dallas, set up the Express server with basic routing.

Squad creates the .squad/ directory structure — team roster, routing rules, casting state, ceremony config, agent charters, and histories — all seeded with your project context. Each agent spawns to do their work.

What’s inside .squad/?

You own these files. Edit them anytime — change roles, add routing rules, fix decisions. Squad reads them before every spawn. Commit .squad/ to version control. It’s your team’s brain. Anyone who clones the repo gets the team with all their knowledge. Then it spawns Dallas:

🔧 Dallas — setting up Express server with routing
Dallas is on it — building the Express server now.

4. Parallel Fan-Out — The Launch Table

Now give a bigger task to see parallel work:

> Team, build the recipe listing page. We need an API endpoint
> that returns recipes and a React component that displays them.

Squad decomposes the work and launches agents simultaneously:

🏗️ Hicks   — reviewing requirements, defining API contract
⚛️ Ripley  — building RecipeList component
🔧 Dallas  — creating GET /api/recipes endpoint
🧪 Lambert — writing test cases from requirements
📋 Scribe  — logging session

All five agents are working at the same time in separate context windows. The tester writes test cases from the requirements while the implementation is being built — no waiting.

5. Results Labeled by Agent

When agents finish, you see results tagged with each agent’s identity:

🏗️ Hicks — Defined API contract: GET /api/recipes returns
   { recipes: [{ id, title, ingredients, prepTime }] }.
   Decided on cursor-based pagination for large result sets.
⚛️ Ripley — Built RecipeList component at src/components/RecipeList.tsx.
   Uses React Query for data fetching. Card layout with title,
   prep time, and ingredient count.
🔧 Dallas — Created GET /api/recipes endpoint at src/routes/recipes.ts.
   Connected to MongoDB. Supports ?cursor= pagination per Hicks' spec.
   Also added GET /api/recipes/:id for detail view (proactive).
🧪 Lambert — Wrote 8 test cases in test/recipes.test.ts:
   📌 Proactive: Written from requirements while Dallas was building.
   May need adjustment once implementation is final.
   - List returns paginated results
   - Empty database returns empty array
   - Invalid cursor returns 400
   - Detail endpoint returns 404 for missing recipe
   [+4 more]

Behind the scenes, the Scribe merged decisions from each agent into decisions.md and logged the session.

6. Ask “Where Are We?” — Instant Status

At any point, check status:

> Where are we?

The coordinator reads recent logs:

Last session: Recipe listing page (15 minutes ago)
Who worked:
- Hicks defined the API contract (cursor pagination)
- Ripley built RecipeList component
- Dallas created recipes endpoint + detail endpoint
- Lambert wrote 8 test cases
Key decisions:
- Cursor-based pagination for recipe lists
- React Query for frontend data fetching
- MongoDB as database
3 decisions in decisions.md, 4 agent history entries updated.

7. Follow-Up — Watch Decisions Accumulate

Give a follow-up task:

> Now add a search feature. Users should be able to search
> recipes by ingredient name.

Squad fans out again:

🔧 Dallas  — adding search endpoint with ingredient filtering
⚛️ Ripley  — building search UI with ingredient input
🧪 Lambert — writing search test cases
📋 Scribe  — logging session

After completion, check decisions:

> Show me the decisions

### 2025-07-15: Cursor-based pagination for recipe lists
**By:** Hicks
**What:** All list endpoints use cursor-based pagination
**Why:** Scales better than offset pagination for growing datasets
### 2025-07-15: React Query for data fetching
**By:** Ripley
**What:** All API calls use React Query with stale-while-revalidate
**Why:** Built-in caching, refetching, and loading states
### 2025-07-15: Full-text search via MongoDB text index
**By:** Dallas
**What:** Search uses $text index on recipe title and ingredients array
**Why:** Native MongoDB capability, no external search service needed

Every agent reads these decisions before working. As the list grows, the team retains context so you don’t need to restate architectural choices.

8. Set a Directive

You notice something you want to standardize:

> Always use Zod for API input validation

Squad captures it — no agent spawn needed:

📌 Captured. All API input validation must use Zod.

This gets written to decisions.md. Every agent will see it in their next spawn.

9. Export Your Squad

After a productive session, export your team for portability:

squad export

✅ Exported to squad-export.json
   5 agents, 3 skills, 6 decisions

This snapshot contains charters, histories, casting state, skills, and decisions. Import into another repo anytime:

cd ../other-project
squad init
squad import ../my-app/squad-export.json

Tips

• First session is slowest. Agents have no history yet. After 2–3 sessions, they know your conventions.
• Commit .squad/ — your team’s brain. Anyone who clones the repo gets the full team.
• Say “team” for big tasks. The word “team” triggers parallel fan-out across multiple agents.
• Name an agent for focused work. "Dallas, fix the login bug" sends work to one specific agent.
• Directives are sticky. Once captured, they persist across all future sessions.

What to Try Next

• Your Team — How agents form, specialize, and collaborate
• Memory & Knowledge — Decisions, skills, and persistent context
• Existing Repo Scenario — Bring Squad into a project that’s already in flight
