Dev & Engineering Claude Skills
ModLens — Plug-in Vision for Text-Only Models
Gives text-only coding models sight: paste an image, get structured JSON evidence — OCR, layout, and semantics — via a vision bridge.
peon-ping Config Manager
Easily tweak peon-ping's volume, pack rotation, categories, and more by editing its config file.
SkillOpt-Sleep: Sleep-Cycle Self-Improvement for Your Local Claude Agent
Give your Claude agent a nightly offline sleep cycle that reviews real sessions and keeps only validation-gated improvements — no model-weight training.
SkillCheck Free
A read-only linter skill that makes your AI assistant validate SKILL.md files against the agentskills spec, catching structural, semantic and security issues before your users do.
NotebookLM Research Assistant Skill
Let Claude Code query your Google NotebookLM directly for citation-backed answers drawn exclusively from your uploaded documents — no copy-paste, no hallucinations.
Create New Skills (Meta-Skill)
A meta-skill that teaches Claude Code to author new Agent Skills following best practices, turning your domain expertise into reusable, discoverable skill folders.
LeanCTX — Local Context Intelligence Layer
Select, shape, reuse, and recover context before your AI agent reads files or runs commands — one local Rust binary that cuts 60–90% of tokens.
OWASP Security Skill
Injects the latest OWASP standards (2025–2026) into code review and AI app development, so your model builds secure code instead of patching it afterward.
Kaggle Skill
End-to-end Kaggle integration for AI coding agents: competition research, dataset/model downloads, notebook execution, and badge collection.
skill-optimizer: Eval Workbench for Agent Skills
Run deterministic evals of agent skills inside isolated Docker workspaces, benchmark across OpenRouter models, and debug with full traces.
TDD Guard
Automated Test-Driven Development enforcement for Claude Code: blocks skipped tests and over-implementation so your coding agent stays test-first.
Copilot Chat OpenTelemetry Instrumentation
A repository-specific guide for consistent OpenTelemetry instrumentation in Copilot Chat.
PinMe UniwebPay Payment Integration
Write Cloudflare Worker code that takes payments through UniwebPay directly via the SDK — links, checkout, subscriptions, refunds, and webhooks.
Vexor Semantic Code Search
Find files by intent, not exact text — instantly locate where something is implemented, loaded, or defined in a medium or large repo.
Overkill — Architecture Exploration Beyond the Pragmatic Answer
Proposes 3–6 advanced alternatives past your pragmatic solution — advanced data structures, distributed algorithms, niche frameworks, frontier tooling — each scored on a calibrated complexity scale.
Worktree Manager Skill
Create, list, and remove git worktrees with a single command, automatically provisioning isolated ports, databases, and config for parallel development.
Learning Opportunities
Pauses AI-assisted coding to offer science-based 10-15 minute learning exercises, so you build genuine expertise instead of just shipping AI-generated code.
Recursive Decomposition Skill
For tasks spanning 10+ files or 50k+ tokens: split long-context work into chunks handled by parallel sub-agents, avoiding the accuracy loss of context rot.
Skills Manager CLI (skm) Skill
Write one skill, sync it to 32 AI coding tools: manage the skill hub, symlinks, and repairs from the terminal with skm.
REA: Reverse Engineer Anything
Connect Claude Code and other agents to the REA MCP server to explain app features without source code, decompile code, and compare versions — down to the binary level.
Claude Skill Template Example
A reference for understanding and creating Claude Code plugin skill templates.
Terminal Title
Automatically writes each Claude Code session's current task into the terminal window title, so you never guess which terminal is which.
Callimachus Recall
One local, searchable index of every AI coding-agent conversation you've had — Claude Code, Codex, Cursor, Gemini and more — so you never redo solved work.
SwiftUI Pro
Review SwiftUI code for modern APIs, maintainability, accessibility, and performance.
