plugin-testing

plugin-testing is a skill for Claude Code, Codex from neurawork-git/n8n-autopilot. It costs 93 tokens per session (1,428 once invoked), scanned A, original, MIT.

A testing procedure for changes to an n8n-autopilot plugin. It requires installing the plugin from its private Git repository and restarting the session before checking the result.

In plain words
What is it for?
Use it to test changes to plugin agents, skills, hooks, scripts, or manifests by committing, pushing, installing, restarting, and verifying registration.
Why use it?
It prevents tests from using stale files or an inconsistent local plugin installation.

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.

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

plugin-testing 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 4d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plugin Testing — push to repo, install from there, nothing else

THE RULE. A change to this plugin (agent def, skill, hook, script, manifest) is tested in exactly one way: commit it, push it to neurawork-git/n8n-autopilot-internal, install the plugin FROM that GitHub repo, restart, verify. Nothing else counts. A change you have not pushed-and-installed has not been tested — you are looking at stale or inconsistently-registered state.

Why (lessons paid for)

  • Hand-copying files into ~/.claude/plugins/cache/.../<version>/ registers inconsistently: agents silently fail to appear, /reload-plugins does not pick up newly-added agents, and you end up with two plugins thinking different things. NEVER do it.
  • A directory-pointer marketplace (extraKnownMarketplaces … source: directory) drifts from the committed truth and produces dual stale installs. Do not use it for testing.
  • Hand-editing .claude/settings.json enabledPlugins desyncs the install records. Use the CLI (claude plugin enable/disable).
  • /reload-plugins is NOT sufficient for newly-added agents/hooks — only a full session restart reliably registers them.

The flow

1. Commit + push + bump version

The installer is version-keyed: install/update no-op if the version already present. So every test cycle bumps the version.

# bump .claude-plugin/plugin.json + .claude-plugin/marketplace.json version (e.g. 4.8.0 -> 4.8.1)
git add -A
git commit -F - <<'MSG'
<type>: <subject>            # clean Conventional Commit — NO leading "@", umlauts correct (ä/ö/ü/ß)

<body>

Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
MSG
git log -1 --format='[%s]'   # verify subject is clean (no stray @)
git push origin main

2. Register the repo marketplace (once) — point at -internal, mind the name collision

We push to and install from neurawork-git/n8n-autopilot-internal (the dev repo). Its marketplace.json name is n8n-autopilot — the same name as the public release marketplace (neurawork-git/n8n-autopilot). Two marketplaces cannot share a name, so:

# if a `n8n-autopilot` marketplace already points at the PUBLIC repo, remove it first:
claude plugin marketplace list                      # check the Source of `n8n-autopilot`
claude plugin marketplace remove n8n-autopilot      # only if it points at the public repo / a directory

claude plugin marketplace add neurawork-git/n8n-autopilot-internal   # GitHub source = single truth

Never add a directory source for this name (that is the cache-drift trap).

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.
