What it does

Invariant Interaction Audit is an agent skill from n1m21n/Infinite. When code establishes a guarantee (in scale, normalized, under budget), check every later control/branch/stage that could undo it, then grep for the same undo-shape in siblings. Use before shipping any invariant-adding fix, as a self-check after writing it, and when a "we already fixed this" bug returns.

Its SKILL.md is about 1.6k 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 Agent Workflows, covering Verification before completion. 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

  • Tasks that involve Verification before completion

Example prompts

  • “we already fixed this”
  • “/invariant-interaction-audit”

Workflow steps

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

  1. Runs after the invariant point on the same value — every subsequent
  2. **Reads a sibling control/field that was never routed through the

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

    No URLs in SKILL.md.

    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

Invariant Interaction Audit loads about 1.6k tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 957 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~83
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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 957 words (~1,646 tokens).

“Before writing (or right after writing) any code that establishes a guarantee — "note stays in scale," "value stays normalized," "budget stays under N," "state stays consistent" — check every OTHER control, branch, or downstream stage in the same node/function/pipeline…”
