Communicate with remote agents via A2A protocol, discover available agents, and ask the human owner for clarification via the A2A Hub. Use when asked to send messages to other agents, discover what agents are available, or when you need human input to proceed. **Triggers — use this skill when:** - You need human input to proceed (approval, decision, clarification) - User asks to "send a message to another agent" - User asks to "discover agents" or "what agents are available" - You're stuck and need to escalate to the owner - A long-running task needs human approval before continuing --- # A2A — Agent-to-Agent Communication & Human-in-the-Loop ## Tools | Tool | Purpose | |------|---------| | `a2a_discover` | Find remote agents on the hub or static registry | | `a2a_send` | Send a message to a remote agent by name, ID, or URL | | `ask_owner` | Ask the human owner a question (non-blocking) | --- ## ask_owner — Human-in-the-Loop Use `ask_owner` when you **genuinely cannot proceed** without human input. The tool submits your question to the hub and **returns immediately** — it does NOT block your session. When the owner responds, a **fresh pi subprocess** is automatically spawned with your handoff context + the owner's answer to continue the work. ### How It Works 1. You call `ask_owner` with a question + handoff context 2. The question is submitted to the A2A Hub — you get an immediate confirmation 3. You continue with other work or end your session 4. The owner answers through the hub's web UI (could be minutes or hours later) 5. A background poller detects the response 6. A fresh `pi` subprocess is spawned with a self-contained prompt containing: - The original question - The owner's response - Your full handoff context (done, remaining, decisions, etc.) 7. The new session picks up where you left off — no prior conversation context needed ### When to Use - **Approval needed** — destructive operations, merging PRs, deploying - **Ambiguous requirements** — multiple vali
Skill files are scattered across GitHub and communities, difficult to search, and hard to evaluate. SkillWink organizes open-source skills into a searchable, filterable library you can directly download and use.
We provide keyword search, version updates, multi-metric ranking (downloads / likes / comments / updates), and open SKILL.md standards. You can also discuss usage and improvements on skill detail pages.
Sort by downloads/likes/comments/updated to find higher-quality skills.
4. Which import methods are supported?
Upload archive: .zip / .skill (recommended)
Upload skills folder
Import from GitHub repository
Note: file size for all methods should be within 10MB.
5. How to use in Claude / Codex?
Typical paths (may vary by local setup):
Claude Code:~/.claude/skills/
Codex CLI:~/.codex/skills/
One SKILL.md can usually be reused across tools.
6. Can one skill be shared across tools?
Yes. Most skills are standardized docs + assets, so they can be reused where format is supported.
Example: retrieval + writing + automation scripts as one workflow.
7. Are these skills safe to use?
Some skills come from public GitHub repositories and some are uploaded by SkillWink creators. Always review code before installing and own your security decisions.
8. Why does it not work after import?
Most common reasons:
Wrong folder path or nested one level too deep
Invalid/incomplete SKILL.md fields or format
Dependencies missing (Python/Node/CLI)
Tool has not reloaded skills yet
9. Does SkillWink include duplicates/low-quality skills?
We try to avoid that. Use ranking + comments to surface better skills:
