Field domain transfer operators (reduce, map, broadcast, resample, downsample).

  • A kernel needs data from another rate

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Field Domains is an agent skill from n1m21n/Infinite. Field domain transfer operators (reduce, map, broadcast, resample, downsample). Use when a kernel needs data from another rate, or on an incomparable-domain join error.

Its SKILL.md is about 4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with C++. The repository describes itself as: Infinite is a free, open-source node-based audiovisual workstation by Naman Soni (n1m21n): real-time GPU compositing, 3D, modular synths, VST3/AU hosting.

When your agent uses it

  • A kernel needs data from another rate
  • On an incomparable-domain join error

Example prompts

  • “/field-domains”

Workflow steps

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

  1. Invariants
  2. The five operators
  3. broadcast — the one you never write
  4. reduce — many → one
  5. map — one per element
  6. resample — read domain A while standing in domain B
  7. downsample — run at a fraction of the ambient rate
  8. Cost table — every crossing on one page
  9. Worked example — audio into geometry
  10. Worked example — geometry into pixels
  11. Exit criterion for a transfer-operator change

What it can do on your machine

Read from SKILL.md and the folder at commit a5c9ad0. 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.

    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 Domains loads about 4k tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 2,065 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~4k

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 2,065 words (~4,036 tokens).

“Field's domain transfer operators — reduce (many to one), map (one per element), broadcast (one to many, implicit and never written), resample (read domain A while standing in domain B) and downsample (run at a fraction of the ambient rate)…”
