Comet is a resumable workflow and Skill platform for AI coding. It provides two independent requirements workflows: self-contained Native for strong models such as Fable 5 and GPT-5.6, and Classic for lower capability tiers through OpenSpec and Superpowers. Together with Skill Creator, Eval, and publishing gates, they form one toolchain from requirements and archiving to Skill distribution.

​
What You Can Do with Comet

  • Use /comet to enter Native or Classic from project configuration and drive a product or code change from idea to archive.
  • Use /comet-any to distill your own workflow into a reusable Skill.
  • Use comet eval to generate pre-publish evidence for a Skill.
  • Use comet publish to review, approve, publish, and distribute /comet-any artifacts.
  • Use comet status and comet doctor to see the current phase, next step, and recovery recommendations.

What’s Different from Ordinary Prompts

Ordinary prompts rely on conversation history. Comet relies on file-based state and inspectable evidence.

Main Entry Points

Invoke /comet for project changes. It reads project configuration and enters the Native or Classic workflow below. Workflow-specific Skills are permanent internal entries and advanced debugging surfaces, not commands users normally need to remember.

Native workflow

For strong models such as Fable 5 and GPT-5.6: retain requirements, state, and evidence while letting the model choose implementation methods.

Classic Spec workflow

For models below the Fable 5 or GPT-5.6 tier that benefit from finer phase guidance through OpenSpec and Superpowers.

CLI Console

Suited for installation, diagnostics, updates, Skill management, evaluation, and publishing.

/comet-any Skill Creator

Suited for creating, optimizing, or composing reusable Skills.

Skill Evaluation System

Suited for verifying Skill behavior with browsable reports and using them as publishing evidence.
Want to know how Comet’s approach maps to industry practices? This article lists, by dimension, every Comet practice across evaluation methodology, runtime and workflow, and Skill creation and distribution, noting which industry references (SkillsBench, LangChain, Tencent, Alibaba, etc.) they correspond to.

What You Get After Installation

comet init installs the Comet Skills, Rules, Hooks, scripts, and platform adapter files to a project-level or global location of your choice. The Comet 0.4.0-beta.1 runtime depends only on Node.js. The built-in state, guard, handoff, and archiving scripts are all executed through Node entry points — it no longer treats Bash, Git Bash, or WSL as workflow prerequisites.
If you just want to start a project change, read Quickstart first. If you want to create reusable Skills, go straight to Compose Any Skill Quickstart.
