What it does

Field Modifier Presets is an agent skill from n1m21n/Infinite. Writing Field Modifier presets (FieldElementNode::Presets()): reserved P/N/Cd, self-mutation ordering bug, declared outputs vs legacy publish. Use BEFORE adding/editing/debugging a Field Modifier preset, or when one does nothing, mutates wrong, or an output reads frozen.

Its SKILL.md is about 2k 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 Development. It works with C++. 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

  • Development work in your project

Example prompts

  • “/field-modifier-presets”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Reserved names available in every modifier preset
  2. The self-mutation ordering bug - the exact bug "Twist Modifier" had
  3. A modifier only recomputes when something it depends on actually changes
  4. Two different output mechanisms - know which one you're using
  5. What actually makes a modifier preset look good
  6. Before shipping a new preset

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

    Shell commands in SKILL.md call:

    • cmake

    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

Field Modifier Presets loads about 2k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 1,042 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~74
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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 1,042 words (~2,016 tokens).

“How to write a new Field Modifier preset (FieldElementNode::Presets(), src/nodes/FieldElementNode.cpp) - reserved element-domain names (P/N/Cd), the self-mutation ordering bug, declared outputs (output frame float) vs the legacy publish variable, and what makes a modifier preset actually look good on a…”
