ponytail

JavaScript

100

Ponytail injects a rule‑set into AI agent sessions that checks each proposed change against a ladder: need, reuse, stdlib, native feature, dependency, one‑line, then minimum viable code. Benchmarks show ~54% less code, ~20% lower cost, ~27% faster execution, and 100% safety compared to a no‑skill baseline. Installation is a single marketplace add for Claude Code, Codex, Copilot CLI, OpenCode, Gemini/Antigravity, Hermes, CodeWhale, Swival, Devin, and OpenClaw.

Alvarmethod

Shell

73

The pack supplies skills such as teach, probe, learn‑profile, learn‑visual, and learn‑verify. Users run /teach in a learning folder to trigger a quiz picker, see a mermaid DAG of their knowledge edge, receive one reasoning step with a picture‑optional quiz, and lock in understanding via pass/fail, with session data stored in .alvar/. It works with Claude Code, Codex, Grok, Pi, OpenCode, Cursor and any agent supported by the skills CLI.

ssh-clipboard

Rust

68

Install via `npm i -g ssh-clipboard`, run `ssh-clipboard`, and the first-run TUI discovers Tailscale peers or accepts any passwordless SSH connection, installs a per-user background service on each, and keeps them in sync. Every representation a clipboard item offers (text, image, file references, rich types) is preserved, so native macOS Finder file paste and Raycast-style clipboard managers see ordinary system writes. A live `monitor` dashboard shows versions across machines, and updates are coordinated peer-to-peer via npm-version gossip with strict SHA-512 and SHA-256 integrity checks. Headless Linux servers are handled with an opt-in managed Xvfb service on display `:99`. The result is one clipboard that feels local on every trusted machine, with no cloud, no ports, and no new keys.

bare-browser

Python

63

Bare Browser is a privacy-focused, community-shaped Android browser built as a 99-patch series against Chromium 153.0.7999.0. It removes Google tracking, telemetry, and AI integration while keeping real browser extensions, uBlock Origin, background video playback, and media saving. Built in Docker with 32GB RAM and 100GB disk, it targets arm64 devices and is signed with a dedicated RSA 4096 key. The project is BSD-3-Clause licensed, unaffiliated with Google, and maintained by one person. Known limitations include cropped extension popups, a squeezed omnibox with many pinned extensions, no Safe Browsing, and arm64-only support.

hflow

Python

80

HFlow is a pre‑v1 SDK that turns robotics data into a searchable, traceable, and reproducible corpus. It accepts MCAP episodes (or LeRobot v3 datasets), runs user‑written Python transforms, checks, labels, and enrichments, and produces canonical MCAP outputs with provenance stamps. Pipelines are rendered as Airflow DAGs for monitoring, and a DuckDB‑backed Parquet catalog lets you query metadata, quality evidence, and build manifests without touching the underlying recordings. It runs locally with Docker Compose or integrates with existing Airflow deployments, democratizing advanced data tooling for any robotics team.

Hermes3D

TypeScript

77

Hermes3D delivers a self‑hosted 3D office where AI agents appear as workers, collaborate, review pull requests, run standups, and execute tasks side‑by‑side. It supports Hermes (via bundled adapter), custom HTTP runtime providers, and a built‑in demo gateway, with a backend‑neutral UI that persists gateway details and office state locally while streaming agent activity via WebSockets.

scroll-craft

JavaScript

85

scrollcraft is a specialized web-building skill that generates premium scroll-driven websites using three unique page grammars (continuous world, filmic one-shot, documentary), each with proprietary signature interactions. It enforces design rigor through a fingerprint gate requiring differences across grammar, navigation, hero, act shape, closing sequence, and signature move across builds.
