mflux: Skill for Cursor

.cursor/skills/asd-ste100/SKILL.md

asd-ste100 is a skill for Cursor from mflux-community/mflux. It costs 99 tokens per session (3,670 once invoked), scanned A, a copy of asd-ste100, MIT.

A controlled-English writing guide for messages that another agent or computer must read without guessing. Simplified Technical English, or STE100, limits ambiguous words and sentence structures.

In plain words
What is it for?
Use it to rewrite technical text into shorter, clearer instructions for agents, translation systems, or readers who may not be fluent in English.
Why use it?
It reduces misreadings in instructions, error messages, tool descriptions, prompts, and status reports, especially when the text is dense or has serious consequences.

Skill for Cursor

Written for Cursor: installed under .cursor/.

This is mflux-community/mflux's own configuration. It tells Cursor how to work on mflux itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mflux configures →

About the project

MFLUX is a native MLX implementation of generative image models that runs locally on Mac computers. It is for generating images with supported models through command-line tools or a Python API. The catalogue skills and instruction support workflows built around these image-generation models.

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

asd-ste100 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 20d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/ste-lint.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Simplified Technical English (ASD-STE100)

ASD-STE100 is a controlled-language standard built by the aerospace and defense industry (ASD, the AeroSpace and Defense Industries Association of Europe) to stop maintenance technicians from misreading English instructions. The standard removes the two biggest sources of misreading: words with more than one meaning, and sentences with more than one possible structure.

This skill borrows that same discipline for a different reader: an AI agent or a downstream system that has to parse an English string — an error message, a tool description, an inter-agent instruction, a status report — without a human in the loop to resolve ambiguity. If a maintenance technician can misread "close the valve" as an adjective ("the valve that is near") instead of a command, so can a language model.

When to Use This Skill

  • An agent's output (explanation, instruction, log message, tool description) reads as dense, jargon-heavy, or ambiguous.
  • Text will be consumed by another agent, a translation pipeline, or a non-native English reader, and misparsing has a real cost.
  • You are writing a prompt, system message, or tool description and want to remove ambiguity before a model ever sees it.
  • You want a before/after comparison showing exactly which rule was violated and how the rewrite fixes it. Ask for it — the default output is the rewritten text alone (see Output Format).

This skill is not for creative or marketing copy — STE is deliberately flat and literal. Do not apply it to text where voice, nuance, or persuasion is the point.

Two Modes

Pick a mode before rewriting. If the user does not say which, infer from the text type. Keep the inferred mode internal. Do not announce it in the default output.

Strict — procedures, error messages, tool and function descriptions, inter-agent instructions, safety text. Anywhere a wrong reading has a cost. Apply every rule below, including the hard length caps and one-word-one-meaning discipline.

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.
