## crystl

crystl rethinks the terminal for the era of agentic coding. Every project you open is treated as a "gem," and every session inside it is a "shard." Run several agents in the same project at once and each shard gets its own git worktree and branch, so parallel sessions stay isolated instead of stepping on each other's files. Off-screen shards throttle to near-zero render work, which means scaling from two agents to a dozen stays light on a Mac.

Coordination is the core of the product. There is an orchestrator mode that monitors worker agents and can read their terminals, a "quest" mode that convenes role-played agents in a shared chat to divide work and debate approaches, and hero shards that summon a single specialist with its own agent, model and persona. A workbench keeps a shared task list in a plain WORKBENCH.md that you and your agents both see, while a project optimizer scores how well a repo is set up for agents and offers one-click fixes. Underneath, the cavrn terminal engine captures every turn, tool call, result and table as structured, agent-readable metadata, so agents can read each other's sessions rather than just watching output scroll by.

Practically, crystl aims to replace a scattered stack. Floating glass cards deliver approvals, questions and notifications without hunting through windows; token tracking shows what each turn and skill costs; an MCP manager connects tools and data; a markdown editor and web preview sit beside your sessions; and remote development over SSH keeps every feature working on a remote machine. There is also a free iPhone app for steering agents over Wi-Fi or via an encrypted relay, and a built-in CLI that lets agents themselves spawn shards and handle approvals. Open models can run locally or through a managed host, so you can mix frontier and open-weight agents in the same workspace.

**Pricing & Plans:** Freemium. A free tier covers getting started and core features, while heavier orchestration capabilities such as orchestrator anointing and controlling other shards via the CLI are gated behind the paid "guild" tier. Pricing details are listed on the site's pricing page and the app is also distributed on the Mac App Store and App Store.

- **Multi-agent parallel sessions:** Run several CLI agents in one project simultaneously, each isolated in its own git worktree and branch so sessions never collide.
- **Orchestration and quests:** Anoint an orchestrator that genuinely monitors workers and reads their terminals, or convene a roundtable of role-played agents in a shared chat via crystl quest.
- **Structured terminal engine (cavrn):** Turns, tool calls, results and tables are captured as agent-readable metadata and rendered fast on the GPU with Metal.
- **Floating approvals and token tracking:** Approval requests, questions and alerts appear as color-coded glass cards, while a panel tracks token burn and estimates turns left.
- **Project-native setup files:** Instructions, task lists and direction live as plain markdown like CLAUDE.md, AGENTS.md and WORKBENCH.md committed with your code, plus an optimizer that scores repo readiness.

**Strengths:** Genuinely model- and agent-agnostic, running any CLI agent including open models; Worktree isolation plus orchestration solves real multi-agent collisions; Agent context lives in plain markdown files inside the project, not locked in a proprietary store; Strong remote development story with SSH support and a free iPhone companion app

**Limitations:** macOS-only, so Windows and Linux users are served by SSH remote development rather than a native app; Some of the most valuable orchestration features are gated behind the paid guild tier; Managing many parallel agents has a real learning curve and demands familiarity with git worktrees

## SkillKit

Coding agents such as Claude Code, Cursor, Codex, Windsurf and GitHub Copilot each have their own way of expressing skills, hooks, MCP tools and instructions. That fragmentation means a skill written for one agent usually needs manual rework before another can use it. SkillKit positions itself as the npm of agent skills: you write a skill once and the CLI translates it into the format each supported agent understands.

Beyond installation, SkillKit bundles a wider toolchain. It aggregates 35+ skill sources and exposes a browsable skill tree of hundreds of thousands of skills, with smart recommendations that analyze your codebase. It can generate skills from natural language using multiple LLM providers, auto-generate agent instructions per project with its Primer feature, capture AI learnings across sessions via session memory, and detect prompt injection, leaked secrets and malicious patterns with a rule-based security scanner. There is also a built-in test framework, workflow orchestration for multi-step sequences, CI/CD generation for GitHub Actions and GitLab CI, and REST, MCP and Python interfaces for runtime skill discovery.

SkillKit is free and open source, and the project states it collects no telemetry. For teams it offers a Git-based .skills manifest so every developer has the same capabilities, and for larger setups a mesh network for synchronizing agents across machines. Because it is a CLI-first developer tool, the learning curve centers on commands rather than a graphical dashboard.

**Pricing & Plans:** Free and open source. SkillKit is installed via npx/npm and the project states there is zero telemetry. No paid tiers or per-seat licensing are published.

- **Cross-agent skill translation:** Write a skill once and translate it into the formats used by all 46 supported agents, including hooks, MCP tools and context conventions.
- **400K+ skill marketplace:** Search and browse hundreds of thousands of skills across 35+ aggregated registries and sources, organized into a hierarchical skill tree.
- **AI skill generation and Primer:** Generate skills from plain language using Claude, GPT-4, Gemini, Ollama or OpenRouter, and auto-generate optimized agent instructions from your codebase.
- **Security scanning and testing:** A 46-rule scanner flags prompt injection, secrets and malicious patterns, while a built-in test framework with assertions validates skills before deployment.
- **Team sync, CI/CD and APIs:** Git-based .skills manifests keep teams aligned, generated GitHub Actions and GitLab CI automate management, and REST, MCP and Python clients support runtime discovery.

**Strengths:** Free and open source with no telemetry; Covers a very wide range of agents in one CLI; Bundles security scanning, testing and CI/CD beyond simple installation; Team manifests and REST/MCP APIs support both small teams and platform use

**Limitations:** Command-line first, so there is no polished point-and-click interface; Aggregated community skill sources vary in quality and maintenance; Compatibility across older or niche agents can be partial rather than full
