Skill Claude CodeCodex
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
Skill Claude CodeCodex
Use when a raw prompt needs rewriting or sharpening, when the user says "rewrite this prompt", "make this prompt better", or asks for a prompt to hand to another agent. Also use before launching any autonomous, long-running, parallel or expensive run (/loop, subagent fan-out, worktrees, overnight work), and whenever a…
Skill Claude Code
Use when starting a brand-new project that needs AI-agent context (CLAUDE.md, AGENTS.md, skills, rules, MCP, spec workflow) set up from day one. Discusses goals → matches catalog know-how → creates a new GitHub repo with everything wired in. Keywords: harness engineering, bootstrap project, context engineering…
Skill Claude CodeCodex
Proactively analyzes the codebase and generates specialized subagents and skills to standardize agentic workflows.

Skill Claude CodeCodex
A set of rules for choosing the right kind of DeepSeek Harness extension before building it. It explains the differences between bundles, local patches, agent presets, skills, and temporary runtime plugins.

Skill Cursor needs its repo
The YAML behaviour contract: MAF-native kind: Prompt agent documents loaded by AgentFactory, seed-owned voice documents, profiles, =Env. and {{ runtime. }} placeholders. Load before changing instructions, models, tools, voice, or VAD.
Skill Claude CodeCodex
Retrofit an existing skills/plugins/agents repository into an APM-compliant package. Use when a repo contains SKILL.md files, a plugin.json, AGENTS.md/CLAUDE.md, MCP manifests, hooks, slash commands, or sub-agents but has no apm.yml (or has an incomplete one), and the user wants it installable via apm install…
Skill Claude CodeCodex
Initialize or improve AGENTS.md files that define how coding agents operate in a repo. Use when asked to set up or replace an agent init command (Codex, Claude), standardize multi-agent behavior, or audit an existing AGENTS.md for clarity, commands, boundaries, and repo-specific context. For Claude Code, also create…
Supersynergy/agent-token-saver-skill-router
Skill Claude Code
Use when an agent has many skills/tools/prompts and must cut prompt tokens by routing adaptively. Runs routing outside model context when possible, indexes metadata on disk, lazy-loads one primary plus up to four complementary support skills, and benchmarks savings across agents.
Skill Claude CodeCodex
Demonstrates how to ship an Agent Skill from an npm package via skill-indexer. Use when learning how to author a skill or as a template for new skills.
Skill Claude CodeCodex
Create new skills, modify and improve existing skills, and measure skill quality. ALWAYS use this skill when users want to create a skill from scratch, edit or optimize an existing skill, extract a skill from a conversation, test a skill, or optimize a skill's description for better triggering accuracy. Also trigger…
Skill Claude CodeCodex
Strict autonomous delivery loop that runs deep-interview, ralplan, ultragoal, code-review, and ultraqa in order with automatic re-planning when gates are not clean. Use on "autopilot", "autonomous", "build me", "create me", "make me", "full auto", "handle it all", or "I want a/an…".
Skill Claude CodeCodex
A lightweight way to divide coding work into task groups, assign each group to a coding agent, and review the results in stages. The main agent plans and checks the work while each worker handles its assigned batch.
Skill Claude Code
Cross-domain AI skill asset manager. Discover, analyze, migrate, and sync your Skills, Memory, and Preferences across 8 AI platforms (Claude, Codex, Cursor, Copilot, Gemini, VS Code, Windsurf, OpenClaw). Features smart matching, hook automation, security scanning, growth gamification, and cross-device sync.
Skill OpenCode

Skill Claude CodeCodex
High-stakes work: debug, migrate, refactor, verify.
Skill Claude CodeCodex
AgentOS uses a modular 3-tier ReAct reasoning engine. The AI (Gemini 2.0 Flash / Claude Sonnet 4.6 / GPT-4o / Ollama) automatically discovers, chains, and executes these skills via the Tool Registry and Skill Loader.
Skill Claude Code
A toolkit for creating, testing, and improving skills for the opencode coding agent. A skill is a reusable set of instructions for a particular workflow.
Sunwood-ai-labs/delegate-to-grok-skill
Skill Codex
Delegate coding, repository inspection, comparisons, web research, and public X search from Codex to the locally installed Grok Build CLI on Windows. Use when a user asks to run or consult Grok, resume Grok Build authentication, compare Codex and Grok, inspect or modify a project with Grok, or perform public X…
Skill Claude Code
Review the user's recent AI coding threads across Claude Code, OpenAI Codex, and Cursor to learn how THEY prefer to work — the preferences and corrections they keep repeating — and to spot places where a missing rule or script made the agent repeat work, then propose and (on approval) write those updates back into…
Skill Claude CodeCodex
Opt-in only. Write, resume, or fetch/hydrate a named Cursor ↔ Claude Code handoff under .scratch/handoffs/. File first; else hydrate from the other tool's local session store (confirm required). Diff check warns if shipped ≠ tree — never blocks. Switch-only, not live sync. Do not run proactively.
Skill Claude CodeCodex
A routing skill that searches a library of more than 300 skills and identifies the best match for a task. It is used when no currently installed skill fits or when someone asks to find a skill.
