# Fission-AI/OpenSpec

> OpenSpec is a spec-driven development framework for AI coding assistants: it turns ideas into Markdown specs with requirements and scenarios before any code is written. It supports 30+ tools (Cursor, Copilot, Codex, etc.) and cross-repo planning via Stores.

## Useful for

- Plan a feature with /opsx:propose to get proposal, specs, design and tasks before coding
- Run /opsx:explore to have the AI read the codebase and suggest an approach
- Share team requirements across repos in a separate planning repo via Stores

## Why it’s here

- Star-counter measurements on 2026-10-28 (UTC), 00:05–11:25: 73168 → 73229 stars (+61). This is the change over that interval.
- Estimated end-of-day forecast: about +124 stars, using observed gains and the previous day.
- About 14 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 5,011
- Issues and pull requests: 1,915
- Watchers: 283
- Average over the last week: 96 per day
- Usual pace: 107 per day
- Latest release: v1.15.0 (2026-10-24)

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
