Simplified Technical English as an Agent Skill for LLMs

Repository0xpili/simplified-technical-englishTool

An open-source project provides prompt guidelines and checking tools to help LLMs like Claude write and review technical documentation according to the ASD-STE100 standard.

Key points

  1. Implements the ASD-STE100 standard (Issue 7, 2017) for controlled technical English within LLM prompts.
  2. Includes 53 writing rules, an approved dictionary of 869 words, and substitution lists for unapproved terms.
  3. Features a standalone Python 3 script (ste_check.py) to check sentence length, paragraph size, passive voice, and word compliance.
  4. Integrates directly as a Claude skill (~/.claude/skills) or can be copied into the system prompt of other LLMs.

Why it matters

Technical documentation in aerospace, defence, and manufacturing requires high clarity and ease of translation. This skill embeds formal, controlled-language constraints directly into AI writing workflows.

Analysis

Created by 0xpili, this repository tackles verbose and ambiguous technical writing. It targets technical writers and engineers who produce manuals adhering to ASD-STE100. Technically, it relies on structured Markdown instruction files (SKILL.md, word lists, rules) alongside a dependency-free Python 3 validation script. While the script detects rule violations like sentence length or passive voice, it cannot check semantic context, necessitating human review for critical texts. With 790 stars and clear acknowledgement of its limits, the project provides a practical foundation for controlled technical writing with LLMs.
