# crossr-skills
**Where the Cross meets clean code.**
High-quality agent skills and a battle-tested harness for building reliable, long-running AI coding agents.
> Forged in the Cross. Built for craft.
---
## Live Public Presence
This repository dogfoods its own harness. The public website and documentation were built using the exact process described here.
- **Marketing Site**: [https://scull7.github.io/crossr-skills/](https://scull7.github.io/crossr-skills/)
- **Documentation**: [https://scull7.github.io/crossr-skills/docs/](https://scull7.github.io/crossr-skills/docs/)
---
## What is this?
A curated collection of **Agent Skills** (`.agents/skills/`) plus a complete, self-hosting **harness process** for teams that want their AI agents to ship production-grade code across many sessions.
The skills strictly follow the [agentskills.io](https://agentskills.io) specification. The process layer (stacked PR discipline, multi-tier verification, PETC loop, GAN reviews, HTML as a first-class human artifact, etc.) is defined in [HARNESS-SPEC.md](HARNESS-SPEC.md).
New projects can be bootstrapped in minutes with:
```bash
./scripts/harness-bootstrap /path/to/your-project
```
---
## Quick Start
```bash
git clone https://github.com/scull7/crossr-skills.git
./crossr-skills/scripts/harness-bootstrap /path/to/your-new-project
cd /path/to/your-new-project
just harness-validate
```
This creates a full harness including `AGENTS.md`, `features.json`, `progress.md`, `justfile`, and the canonical `.agents/skills/` directory.

## Skills
All skills are designed with the same standards applied to production Rust code: functional purity, stratified design, zero technical debt, and handover-clean artifacts.
| Skill | Purpose | Category |
|------------------------|------------------------------------------------------|---------------|
| `code-writer` | Core coding philosophy (Grokking Simplicity + SICP) | Foundation |
| `rust-code-writer` | Idiomatic, pure, stratified, flat-combinator Rust | Rust Core |
| `rust-code-reviewer` | Ruthless code quality guardian | Quality |
| `rust-code-tester` | Obsessive test coverage & error-path verification | Quality |
| `rust-architect` | Torvalds-style system-level architecture gatekeeper | Architecture |
| `rust-team-lead` | GAN orchestrator for reliable multi-agent workflows | Orchestration |
| `rust-axum-backend` | Clean, layered Axum HTTP APIs with policy gates | Backend |
| `rust-frontend` | Leptos + WASM + Polars with strong anti-slop guidance| Frontend |
| `rust-tui` | ratatui Component + Action + two-phase dispatch | TUI |
| `rust-errors` | Layered `thiserror` error handling (no `anyhow`) | Backend |
| `agent-harness` | Full harness process (stacked PRs, GAN, HTML-first) | Harness |
See the [full documentation](https://scull7.github.io/crossr-skills/docs/) for detailed guidance on each skill.

## The Harness
This repo ships with a complete, production-proven harness:
- **HARNESS-SPEC.md** – The canonical process specification
- Stacked, reviewable PRs (< 10 min deep review target)
- Mechanical GAN reviews (Reviewer + Tester + Architect agents)
- `features.json` + `progress.md` for traceable incremental work
- `scripts/harness-bootstrap` – one-command harness installation
- HTML as the primary human-facing artifact format
Everything in this repository (including the public website) was built using this harness.
---
## Core Philosophy
> “Write code that is layered, modular, and built from pure calculations operating on immutable data; isolate all actions; prefer the language’s standard library; use abstraction and higher-order functions to control complexity so that any human reader can understand and safely modify the system.”
This mindset applies to every skill and to the harness itself.
---
## Principles
- **No garbage** — Every skill is reviewed by `rust-code-reviewer`, `rust-code-tester`, and `rust-architect`.
- **Small and focused** — One skill = one clear responsibility.
- **Self-verifying** — Skills contain their own usage rules and activation statements.
- **Dogfooded** — The harness is used to maintain the harness (and its public site).
---
## Contributing
Contributions are welcome, especially improvements to the harness process and new high-quality skills that follow the same standards.
Please read [HARNESS-SPEC.md](HARNESS-SPEC.md) and follow the stacked PR + GAN discipline used in this repository.
