port-plugin

A conversion workflow for turning Agent Alchemy plugins into formats supported by other AI coding platforms. It uses platform-specific adapters and guides the user through a seven-phase conversion process.

In plain words
What is it for?
Use it to convert plugin components, research the target platform, choose conversion mappings, and complete an interactive export process.
Why use it?
It removes the need to manually rewrite skills, agents, hooks, references, and MCP settings for each platform. Platform compatibility can vary, so the workflow includes research and user decisions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

port-plugin scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 2,620 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plugin Porter

Convert Agent Alchemy plugins (skills, agents, hooks, references, MCP configs) into formats compatible with other AI coding platforms using an extensible markdown-based adapter framework, live platform research, and interactive conversion workflows.

CRITICAL: Complete ALL 7 phases. The workflow is not complete until Phase 7: Summary is finished. After completing each phase, immediately proceed to the next phase without waiting for user prompts.

Critical Rules

AskUserQuestion is MANDATORY

IMPORTANT: You MUST use the AskUserQuestion tool for ALL questions to the user. Never ask questions through regular text output.

  • Every wizard question -> AskUserQuestion
  • Selection questions -> AskUserQuestion
  • Confirmation questions -> AskUserQuestion
  • Yes/no consent questions -> AskUserQuestion
  • Clarifying questions -> AskUserQuestion

Text output should only be used for:

  • Summarizing selections and findings
  • Presenting information and status updates
  • Explaining context or conversion details

If you need the user to make a choice or provide input, use AskUserQuestion.

NEVER do this (asking via text output):

Which plugin groups would you like to port?
1. core-tools
2. dev-tools
3. sdd-tools

ALWAYS do this (using AskUserQuestion tool):

AskUserQuestion:
  questions:
    - header: "Plugin Groups"
      question: "Which plugin groups would you like to port?"
      options:
        - label: "core-tools"
          description: "3 skills, 2 agents — Deep analysis, codebase analysis, language patterns"
        - label: "dev-tools"
          description: "6 skills, 4 agents — Feature dev, code review, docs, changelog"
        - label: "sdd-tools"
          description: "6 skills, 3 agents — Spec creation, task management, execution"

Plan Mode Behavior

CRITICAL: This skill performs an interactive conversion workflow, NOT an implementation plan. When invoked during Claude Code's plan mode:

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
