Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00182 | $0.11238 |
| Opus 5 | $0.00091 | $0.05619 |
| Sonnet 5 | $0.00036 | $0.02248 |
| Haiku 4.5 | $0.00018 | $0.01124 |
Grade A, and why
port-master 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 5d 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 — 1,028 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Port Master
Extract the platform-agnostic intent from Claude Code plugins, producing clean markdown files that any agent harness developer can read and adapt. The output preserves the what and why of each skill, agent, and hook while removing implementation details tied to Claude Code.
The goal is portability through clarity — a developer familiar with any agent framework should be able to read the output and integrate it into their system without needing to understand Claude Code's internals.
Three output modes are supported:
- Full mode (default): Produces skills, agents, and hooks — preserves the original component structure in generic format. Supports two output layouts:
- Per-group (default): Each plugin group gets its own subdirectory with separate manifest and integration guide.
- Unified (
--unified): All groups merged into a single directory — one manifest, one integration guide, components organized by type. Cross-group dependencies become internal. Only meaningful when converting multiple groups.
- Flatten mode (
--flatten): Produces skills only — agents are converted to skills, hooks are absorbed into alifecycle-hooksskill. Use this for agent harnesses that only support skills and not agents or hooks. - Nested mode (
--nested): Agents become pure markdown instruction files nested within their parent skill'sagents/directory. Hooks are absorbed into alifecycle-hooksskill. Use this for harnesses that support sub-agent delegation but use skills as the primary organizational unit.
Complete ALL 5 phases. After completing each phase, immediately proceed to the next without waiting for user prompts.
Critical Rules
AskUserQuestion is MANDATORY
Use the AskUserQuestion tool for ALL questions to the user. Never ask questions through regular text output.
- Selection questions → AskUserQuestion
- Confirmation questions → AskUserQuestion
- Clarifying questions → AskUserQuestion
Text output is only for status updates, summaries, and informational context.
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.
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.

port-master is a skill published in the GitHub repository sequenzia/agent-alchemy (44 stars, last pushed 3mo ago), licensed MIT. It adds 182 tokens to every session and 11,238 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
