What it does

Plugin Host Hardening is an agent skill from n1m21n/Infinite. Strategy and diagnosis for third-party VST3/AU plugins crashing, hanging or silencing Infinite. Use when a user names a crashing plugin (Serum, Pigments, ...), pastes a macOS .ips crash report, asks "why does AU work but VST3 doesn't", or before touching PluginVST3.mm or Platform.mm plugin paths.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Mobile testing and debugging. It works with macOS. The repository describes itself as: Infinite is a node-based audiovisual workstation — real-time GPU video compositing, procedural 3D geometry, modular synths, DSP, and VST3/AU plugin hosting.

When your agent uses it

  • A user names a crashing plugin (Serum
  • Pastes a macOS .ips crash report
  • Asks why does AU work but VST3 doesnt
  • Before touching PluginVST3.mm

Example prompts

  • “why does AU work but VST3 doesn”
  • “/plugin-host-hardening”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Find the faulting thread (Triggered by Thread: N) and read its
  2. Check the dispatch queue on the faulting thread. If it is not
  3. Read the exception type
  4. Check Binary Images for the culprit's real identity — the plugin's
  5. Only then open the named function in our source and decide the tier.

What it can do on your machine

Read from SKILL.md and the folder at commit 4e7ffe5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Plugin Host Hardening loads about 2.8k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 1,486 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,486 words (~2,785 tokens).

“The strategy and diagnostic method for stopping third-party VST3/AU plugins from crashing Infinite. Use whenever a user reports that a specific plugin crashes/hangs/silences the app (Serum, Pigments, ZENOLOGY, Massive X, FabFilter, EZkeys and friends), whenever they paste a macOS crash…”
