🌱 Spec Kit 
 Build with a spec, fix a bug, or assess an idea — with your coding agent.

Spec Kit is an open source toolkit that gives AI coding agents structured
processes, reusable templates, and documented outcomes. Start with a ready-made
process, customize it, or bring your own.
## Choose your process
| What you need | Process | Outcome |
| --- | --- | --- |
| Build a feature or application | Spec-Driven Development | A specification carried through planning, implementation, and convergence |
| Diagnose and repair broken behavior | Bug fixing | An assessed cause, scoped fix, and recorded verification |
| Decide whether an idea deserves investment | Idea assessment | An evidence-backed go, clarify, or stop decision |
| Adopt or create a different process | Your own process | A process adapted or assembled from reusable primitives |
These are independent entry points, not mandatory phases. SDD ships in core;
bug fixing and assessment are bundled extensions you install when needed, and
the primitives below let you adopt or create other processes.
## Capabilities
Spec Kit combines ready-to-use processes with composable mechanisms:
| Capability | Spec Kit mechanism |
| --- | --- |
| Connect to or switch between coding agents | Integration |
| Add a command, quality gate, or complete process | Extension |
| Connect a process to an external tool or service | Extension |
| React to coding-agent lifecycle events | Extension runtime event |
| Run extension commands before or after Spec Kit commands | Extension hook |
| Adapt templates, commands, terminology, or methodology | Preset |
| Enforce organizational or regulatory standards | Preset |
| Override a template for one project | Project-local override |
| Automate prompts, commands, gates, and shell tasks | Workflow |
| Modify an installed workflow without forking it | Workflow overlay |
| Add reusable executable behavior to workflows | Workflow step |
| Install a curated setup for a role or team | Bundle |
| Discover community components | Catalog |
| Host a private catalog of approved components | Catalog |
| Access private catalogs and component downloads | Authentication |
| Work offline or behind a firewall | Local sources and self-hosted catalogs |
| Inspect which layer supplies a command, template, or script | Artifact inventory |
Search the active catalogs with commands such as `specify extension search`,
`specify preset search`, `specify workflow search`, and `specify bundle search`.
Spec Kit includes community catalogs, and organizations can add their own
curated sources. Catalog listings are not audits or endorsements, so review
community source code before installing or running it.
## Get started
You need Python 3.11+, uv,
and a supported AI coding agent on Linux, macOS, or Windows.
Run these commands in your terminal to install Spec Kit and create a project.
This example uses GitHub Copilot.
