manimce-best-practices
by adithya-s-kTrigger when: (1) User mentions "manim" or "Manim Community" or "ManimCE", (2) Code contains `from manim import *`, (3) User runs `manim` CLI commands, (4) Working with Scene, MathTex, Create(), or ManimCE-specific classes. Best practices for Manim Community Edition - the community-maintained Python animation engine. Covers Scene structure, animations, LaTeX/MathTex, 3D with ThreeDScene, camera control, styling, and CLI usage. NOT for ManimGL/3b1b version (which uses `manimlib` imports and `manimgl` CLI).
manim-composer
by adithya-s-kTrigger when: (1) User wants to create an educational/explainer video, (2) User has a vague concept they want visualized, (3) User mentions "3b1b style" or "explain like 3Blue1Brown", (4) User wants to plan a Manim video or animation sequence, (5) User asks to "compose" or "plan" a math/science visualization. Transforms vague video ideas into detailed scene-by-scene plans (scenes.md). Conducts research, asks clarifying questions about audience/scope/focus, and outputs comprehensive scene specifications ready for implementation with ManimCE or ManimGL. Use this BEFORE writing any Manim code. This skill plans the video; use manimce-best-practices or manimgl-best-practices for implementation.
manimgl-best-practices
by adithya-s-kTrigger when: (1) User mentions "manimgl" or "ManimGL" or "3b1b manim", (2) Code contains `from manimlib import *`, (3) User runs `manimgl` CLI commands, (4) Working with InteractiveScene, self.frame, self.embed(), ShowCreation(), or ManimGL-specific patterns. Best practices for ManimGL (Grant Sanderson's 3Blue1Brown version) - OpenGL-based animation engine with interactive development. Covers InteractiveScene, Tex with t2c, camera frame control, interactive mode (-se flag), 3D rendering, and checkpoint_paste() workflow. NOT for Manim Community Edition (which uses `manim` imports and `manim` CLI).
rl-env-from-description
by adithya-s-kTurns a user's plain-English description of an RL training environment into runnable code across the four target frameworks — OpenEnv, OpenReward (ORS), Verifiers, and NeMo Gym. Use whenever someone describes an environment they want to build ("I want to train an agent that does X", "make an env where the model has to Y"), asks to scaffold a new env, asks to port an existing env to one of these frameworks, or asks how to design tools/rewards/state for a new env. Use even when the user does not explicitly say "RL environment" — descriptions like "agent that browses the web", "tool-calling agent for SQL", or "game-playing agent" all qualify. Drives the full flow — clarifying interview, env-name selection, shared-domain extraction, per-framework implementation, and rollout-based smoke tests.
generate-verifiers-env
by adithya-s-kBuilds a Verifiers (PrimeIntellect) variant of an RL environment. Use whenever someone asks to scaffold a Verifiers env, port to Verifiers, build an in-process toolkit, set up a `vf.ToolEnv` with a Rubric, or wire up a TRL `GRPOTrainer` rollout. Verifiers is the right framework when the user wants in-process tools (no HTTP server), structured tool calling driven by plain Python functions, composable reward rubrics with multiple grader functions, fast iteration with no Docker, or the cleanest path from prototype to TRL training. Output is a runnable `<env_dir>/verifiers/` folder with `env.py` (toolkit + standalone tool functions + `create_verifiers_env`), `rollout.py`, and `pyproject.toml`. Use for prompts like "make a verifiers env for X", "wrap my game in verifiers", or "set up a vf.ToolEnv".
generate-nemo-gym-env
by adithya-s-kBuilds a NeMo Gym (NVIDIA) variant of an RL environment. Use whenever someone asks to scaffold a NeMo Gym Resources Server, port an existing env to NeMo Gym, expose tools as `app.post()` endpoints with cookie-based sessions, add a post-episode `/verify` reward grader, or deploy a NeMo Gym env to HF Spaces. NeMo Gym is the right framework when the user wants HTTP+REST with cookie session handling, raw `requests`-driven rollouts (no SDK client), Ray-based orchestration, or NVIDIA NeMo / TRL training integration with a `responses_create_params` + `ground_truth` dataset format. Output is a runnable `<env_dir>/nemo_gym/` folder with `server.py`, `pyproject.toml`, `Dockerfile`, `configs/<env>.yaml`, and `rollout.py`. Use for prompts like "wrap my env in NeMo Gym", "make a NeMo resources server for X", or "add a post-episode grader to my env".
generate-openenv-env
by adithya-s-kBuilds an OpenEnv (Meta) variant of an RL environment. Use whenever someone asks to scaffold an OpenEnv server, port an existing env to OpenEnv, add MCP tools to an env, or deploy an OpenEnv to HF Spaces. OpenEnv is the right framework when the user wants HTTP+MCP, structured tool calls discovered via `list_tools()`, an optional Gradio UI, sandbox-backed sessions, or deployment as a Docker container / HF Space. Output is a runnable `<env_dir>/openenv/` folder with `server/app.py`, `server/<env>_environment.py`, `pyproject.toml`, `Dockerfile`, and `rollout.py`. Use for prompts like "wrap my game in OpenEnv", "make an MCP env for X", or "add the openenv variant".
generate-ors-env
by adithya-s-kBuilds an Open Reward Standard (ORS) variant of an RL environment using the official `openreward` Python package. Use whenever someone asks to scaffold an ORS env, port to OpenReward, add per-tool-call rewards, deploy to OpenReward.ai, or wrap an existing env in the ORS protocol. ORS is the right framework when the user wants HTTP+REST+SSE, rewards arriving inline with each tool call (not post-episode), task-spec-driven sessions, splits (train/val/test), or deployment to OpenReward.ai or HF Spaces. Output is a runnable `<env_dir>/ors/` folder with `server.py`, `tasks.py`, `pyproject.toml`, `Dockerfile.spaces`, and `rollout.py`. Use for prompts like "wrap my env in ORS", "make an OpenReward env for X", or "add per-call reward to my env".

Standardizing Agent Capabilities with SKILL.md and Model Context Protocol (MCP)
In the rapidly evolving landscape of artificial intelligence, LLM agents (Large Language Model agents) have transitioned from simple text predictors to autonomous problem solvers. To orchestrate complex, multi-step agentic workflows, developers require a standardized format to specify agent capabilities, prompt instructions, system rules, and database bindings. This is where SKILL.md and the Model Context Protocol (MCP) have emerged as standard developer paradigms. SkillMD serves as the central directory for indexing, exploring, and sharing these critical agent configurations.
Our open-source registry currently tracks over 1.7 million collected SKILL.md configurations and system prompts. By compiling agent configurations from active developers on GitHub, we bridge the gap between prompt engineering research and production execution. Whether you are building agents with Anthropic's Claude Code, OpenAI's GPT-4, Google's Gemini, or local models using Ollama and LlamaIndex, standardized skill definitions ensure your agents behave predictably across different runtime environments.
What is the Model Context Protocol (MCP)?
The Model Context Protocol (MCP) is an open-source standard designed to connect LLMs to data sources, developer tools, and external environments. MCP establishes a bidirectional communication channel between client applications (like Cursor, Claude Desktop, or custom agent systems) and servers hosting data or capabilities. Standardizing instructions via SKILL.md enables LLMs to query databases, read local files, execute terminal commands, and integrate third-party APIs. SkillMD allows you to find ready-to-run MCP servers and prompt instructions for various occupations and technical tasks.
The Structure of a Professional SKILL.md File
A valid SKILL.md configuration is designed to be easily read by humans and parsed by LLMs. It contains precise system instructions, trigger conditions, required parameters, and execution examples. Below is the typical architectural blueprint of a professional agent skill:
- Metadata & Core Scope: Declares the name of the skill, author details, target models, and a description of the capability.
- Triggers & Intent Detection: Details semantic triggers that help the agent decide when to invoke this skill.
- System Prompts: Explicit system-level instructions that direct the agent's behavior, personality, safety guardrails, and formatting preferences.
- Capabilities & Tools: Lists the files, databases, or APIs the agent must access to complete the tasks.
- Few-Shot Examples: Demonstrates real inputs and outputs, helping the model generalize behavior through in-context learning.
Optimizing Agent Workflows for Modern LLMs
Writing effective agent skills requires deep knowledge of prompt engineering. With the release of advanced reasoning models like Claude 3.5 Sonnet, ChatGPT o1, and DeepSeek-V3, prompt templates must focus on structured thinking. Developers are encouraged to use XML tags (e.g., <thought>, <context>, and <rules>) to isolate execution boundaries. Standardized prompts prevent agents from suffering from context drift, ensuring that long-running tasks remain aligned with the initial system parameters.
Exploring by SOC Occupations and Creator Profiles
What makes SkillMD unique is its taxonomy. Instead of simple text search, we parse and organize files according to the Standard Occupational Classification (SOC) system. This means you can discover skills written for Computer and Mathematical roles, Business and Financial operations, Legal, Design, and and Educational Instruction fields. By tracking creator profiles, developers can study how different teams organize their custom instructions, compare version updates, and fork public configs for specialized enterprise use cases.
SkillMD operates as a high-performance index running on a fast Go backend and a highly responsive Astro SSR frontend. All search queries execute in milliseconds, featuring smart debouncing to prevent multiple API requests while keeping user data secure.
