ASD-STE100 Skill — Simplified Technical English for Agent Output
A Claude Code skill that rewrites dense, ambiguous English into ASD-STE100 Simplified Technical English (STE) — the controlled-language standard the aerospace and defense industry built so aircraft maintenance instructions cannot be misread.
This skill repurposes that same discipline for a different reader: an AI agent parsing another agent's output, a tool description, an error message, or an inter-agent instruction, with no human in the loop to resolve ambiguity.
Why STE, and Why for Agents
STE exists because a misread instruction on an aircraft can kill people, and the intended readers were often not native English speakers with no author to call for clarification. The standard's fix: one meaning per word, active voice, simple tenses, one instruction per sentence, short sentences, no dropped words.
An LLM agent parsing another agent's output is in a strikingly similar position — no back-channel, no way to ask "did you mean X or Y?" The same rules that keep a mechanic from misreading a torque spec keep a downstream agent from misreading a tool description or an inter-agent message.
Before / After
| Before | After |
|---|---|
| "This tool will attempt to synchronize state across the various backends that have been configured, and if a conflict is detected it may resolve it automatically depending on the strategy that has been set, or otherwise it will surface the conflict for manual review." | "The tool synchronizes state across the configured backends. If it finds a conflict, it checks the current strategy. If the strategy allows automatic resolution, the tool resolves the conflict. If not, the tool reports the conflict for manual review." |
| "An error may have occurred while processing your request due to a possible mismatch in the expected data format, which could be caused by an outdated client version." | "The request failed. The data format did not match what the server expected. Check your client version — an outdated client is the most common cause." |

What This Skill Does
- Reads the input English text for meaning.
- Flags every rule violation sentence-by-sentence: ambiguous word choice, present-perfect/complex tense, passive voice with an unclear actor, multi-instruction sentences, oversized noun clusters, dropped words, sentences over length.
- Rewrites each flagged sentence — without dropping any fact, condition, or scope qualifier from the original. If a shorter phrasing would lose required precision, it keeps the longer phrasing and flags the trade-off instead of silently simplifying.
- Outputs a before/after table plus a short note on anything deliberately left unsimplified.
It does not reproduce ASD's official ~900-word approved dictionary — that is ASD's own free-to-download standard. This skill applies the underlying principle (plainest available word, used the same way every time) rather than checking against a fixed word list. For certified STE-compliant documentation, use the real standard.

Installation
git clone https://github.com/danyuchn/asd-ste100-skill ~/.claude/skills/asd-ste100
Usage
Trigger with a request to simplify or clarify English text:
/simplify this tool description into STE
Rewrite this error message so an agent can't misparse it
Apply ASD-STE100 to this instruction
Or paste text and ask Claude to "simplify this for STE100" / "reduce ambiguity in this output."
Scope
Built for: agent-to-agent messages, tool/function descriptions, error messages, system prompts, inter-agent instructions — any English text a machine or non-native reader has to parse without a human to ask.
Not built for: creative writing, marketing copy, or anything where voice and nuance are the point — STE is deliberately flat and literal by design.
