## What it does

This skill directs the agent to generate technical procedures, warning blocks, and maintenance guides following the ASD-STE100 specification. The foundation rests on a single principle: one word holds only one meaning. All instructional steps begin with an active imperative verb rather than passive phrasing or polite suggestions.

The workflow enforces strict structural ceilings. Procedural sentences cannot exceed 20 words, while descriptive statements stop at 25 words. Chains of stacked nouns are capped at three items. The skill also requires putting conditional clauses at the start of a sentence and replacing ambiguous pronouns with clear technical terms. Detailed formatting for safety alerts (WARNING, CAUTION, NOTE) resides in `references/REFERENCE.md`, which the agent reads on demand.

Operating this skill requires only standard Markdown support within the agent environment, with no external toolchains needed.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add surendranb/writing-skills --skill asd-ste100 -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/asd-ste100/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/asd-ste100/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add surendranb/writing-skills --skill asd-ste100 -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/asd-ste100/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add surendranb/writing-skills --skill asd-ste100 -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/asd-ste100/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**

## When to use it
- convert technical procedures into Simplified Technical English
- enforce a 20-word limit on instructional sentences
- eliminate noun clusters and ambiguous pronouns in manuals
- rewrite passive instructions into active imperative voice

## Example prompts
- Rewrite this maintenance manual using ASD-STE100 rules
- Check this procedure for noun clusters and sentence length violations
- Convert this draft into imperative instructions under 20 words per step

# ASD-STE100 Simplified Technical English

Control vocabulary and syntax to eliminate ambiguity in technical documentation.

## The core rule

**One word, one meaning. Imperative voice for instructions. Maximum 20 words per sentence.**

Workflow: `choose approved STE vocabulary` → `write imperative command` → `restrict sentence length to 20 words max` → `verify zero ambiguity`.

## Mechanics

1. **Approved vocabulary.** Use only words from the ASD-STE100 dictionary or approved technical nouns.
2. **Imperative commands.** Start steps with an action verb ("Remove the bolt", not "You should remove the bolt").
3. **Word count limits.** Maximum 20 words for procedural sentences; maximum 25 words for descriptive sentences.
4. **No noun clusters.** Maximum of 3 nouns in a sequence (e.g. use "valve control switch" instead of "engine fuel system valve control switch").
5. **Present tense.** Describe current states in present tense; avoid future tense ("The light is on" not "The light will turn on").
6. **No gerunds in titles.** Use simple nouns or infinitives for headings.
7. **Explicit conditions.** Place conditional clauses at the beginning of the sentence ("If the pressure is low, replace the filter").
8. **Approved modifiers.** Avoid vague adjectives like "extreme", "rapid", or "normal" unless quantified.

## Verify

- Sentences do not exceed 20 words for procedures
- Every instruction starts with an active imperative verb
- No noun clusters exceeding 3 words
- All technical terms conform to standard dictionary definitions
- Zero ambiguous pronouns (replace "it" or "they" with specific nouns)

## Do not

- Use words with multiple meanings (e.g., use "fast" or "secure", avoid "fixed")
- Write conditional clauses after the main action
- Use contractions or colloquialisms
- Use passive voice in maintenance steps

## References

For the enforceable limits (sentence/paragraph/noun-cluster caps), safety-text structure (WARNING/CAUTION/NOTE), and punctuation rules, read `references/REFERENCE.md` when a draft is borderline or needs verification — load on demand, not upfront.

## Example transformations

**Before:** "It is recommended that technicians should carefully inspect the aforementioned component assembly for any potential signs of wear prior to system operation."

**After:** "Inspect the component assembly for wear before you operate the system."

**Before:** "When the pressure drops too low, you might want to consider resetting the main system valve."

**After:** "If the pressure is low, reset the main valve."
```
