v0.3.023 June 2026

Start projects your AI agents already understand.

One command writes the AGENTS.md instructions, .specify/ workflows, MCP wiring, and engineering docs your agents read first, in each one's native format.

What it scaffolds

The context your AI agents need, written once.

One neutral source, generated into every agent's native config. Tuned to your stack, ready for any agent.

.agents/
Neutral source of truth. Edit once; every agent regenerates from it.

AGENTS.md core + per-agent addenda

AGENTS.md + bridges
The standard your agents read, plus a native bridge for the ones that need one.

Why it matters

Your agents inherit your conventions on day one.

Skip a week of telling your agent where the linter lives, what the test runner is, or how migrations work. Write it once, ship it with every project.

The build loop

Scaffolding is day one. This is every day after.

The same commands ship with every project. Open a session, spec the work, build in tight cycles, and ship behind a review gate. Then do it again.

  1. Open
    /quickstart

    Loads your priorities, branch, and the feature in flight, so every session starts oriented.

  2. Spec
    /speckit-specify…/speckit-implement

    Turn an idea into a spec, a plan, and tracked tasks before any code gets written.

  3. Buildrepeats
    /dev-check+/checkpoint

    Validate the build, lint, and tests, then commit a checkpoint. Repeat until the feature lands.

  4. Ship
    /session-end→/security-review

    Close the session with a push and handoff notes, then open a PR behind a security review.

The next session opens with /quickstart again.

Spec-kit is an external prerequisite (Python + uv). The loop assumes one developer per branch.

Presets

Any preset, one flag.

Skip the wizard with --preset. Runtime, linter, test runner, and agent context tuned for what you're building.

Web App

Full-stack web app, Next.js + Tailwind.

Dev-stacks dataset · 235 tools

Every tool the toolkit knows, queryable.

235 vetted tools across 5 sections, typed and validated. The CLI resolves dependencies, writes configs, and seeds your docs from it. Import it yourself for the same.
