quickstart

A guided introduction to the Exosuit development framework. It walks through a first sprint, from planning work to delivering a pull request, and explains the framework's automated checks, workflow commands, and project documentation.

In plain words
What is it for?
Use it to learn the framework, check project readiness, and follow a first sprint through planning, implementation, testing, verification, and a shipped pull request. TDD means writing tests to describe the expected behavior before implementing the code.
Why use it?
It helps a new user understand the framework's structure and check whether the project has been set up before starting work. It also explains the expected development cycle.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

quickstart scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

quickstart

Welcome to the Exosuit framework. This guided tour walks you through your first complete sprint, from planning to shipped PR.

Phase 1: Orientation (2 minutes)

Present the framework's core concept:

### How This Framework Works

The framework adds structure to AI-assisted development:

**Three Layers:**
1. **Enforcement:** hooks that auto-format code, scan for secrets, block dangerous commands (automatic)
2. **Workflow:** skills (slash commands) that guide your development process (you invoke these)
3. **Documentation:** knowledge base that compounds across sessions (generated and updated)

**The Core Loop:**

/sprint-start → /story-cycle (repeat) → /sprint-end


Each `/story-cycle` takes a story through: plan → approve → implement (TDD) → verify → commit.

Phase 2: Check Readiness (1 minute)

Run a quick health check:

# Check if bootstrap has been run
if [ -f "docs/architecture/ARCHITECTURE.md" ] && ! grep -q "<!-- " docs/architecture/ARCHITECTURE.md 2>/dev/null; then
    echo "READY: Bootstrap complete"
else
    echo "NOT READY: Run /bootstrap first"
fi

Phase 3: Interactive Walkthrough

Present options using AskUserQuestion:

  • "Walk me through a sprint" (description: "Interactive guided sprint with explanations at each step (15 min)")
  • "Show me all available skills" (description: "Quick reference of every slash command grouped by purpose")
  • "Explain the enforcement layer" (description: "See what happens automatically (hooks, rules, quality gates)")
  • "I want to start building" (description: "Skip the tour, jump to /sprint-start")

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

quickstart is a skill published in the GitHub repository joris887/exosuit (4 stars, last pushed 13d ago), licensed MIT. It adds 23 tokens to every session and 1,314 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
