## When to use

Use this skill when the user asks to:

- Check or rewrite manuals, procedures, warnings, maintenance text, or technical descriptions for STE-style clarity
- Review controlled language / Simplified Technical English wording
- Look up whether a word is approved and what alternatives exist
- Apply safe synonym fixes before a full rewrite
- Explain what a checker `rule_id` means and how to fix it
- Check only locally changed documentation files in a git working tree
- Judge Tier-3 semantic WARNINGs (pronouns, topic sentence, POS) via a review brief

Do **not** use this skill for creative writing, marketing copy, or general English editing unrelated to technical procedures/descriptions.

## Core principles

- Prefer short sentences (procedures ≤ 20 words; descriptions ≤ 25 words).
- Use approved dictionary words; prefer project glossary terms when provided.
- Write procedures in active, imperative mood (one instruction per sentence).
- Avoid progressive/perfect/complex verb stacks; keep multi-word nouns ≤ 3 words.
- Name nouns instead of ambiguous pronouns; put the topic in the first descriptive sentence.
- Use each approved word in its approved part of speech only.
- One meaning per word; do not invent alternate senses.
- Preserve identifiers, measurements, part numbers, and safety information.

## Strict workflow

1. **Multi-file / PR-local docs:** call **`ste_check_changed_files`** first (working tree vs `HEAD`, or pass `base=` for merge-base vs a branch; default globs `*.md` / `*.txt` / `*.rst` / `*.adoc`).
2. **Classify** the text as `procedure` or `description` (or leave as `auto` if unsure).
3. **Check** with MCP: `ste_check_text` (paste) or `ste_check_file` (path). Pass a glossary path when available.
4. **Treat deterministic ERROR findings as authoritative.** Do not dismiss ERROR results based on your own judgment (includes high-confidence `STE-POS-MISMATCH`).
5. **WARNINGs are advisory** (Tier-2 parse confidence or Tier-3 semantic heuristics). Prefer fixing them; leave with rationale only if unclear, unless the user asks to clear warnings too.
6. If unsure what a `rule_id` means, call **`ste_explain_finding(rule_id)`**.
7. **Optionally** call `ste_apply_safe_fixes` first for unambiguous 1:1 synonyms (e.g. `utilize` → `use`), then recheck.
8. Call **`ste_suggest_rewrite`** to get a structured rewrite brief (`prompt` + capped findings + `constraints` + optional `safe_fix_preview`). It does **not** call an LLM — **you** (the host agent) rewrite from that brief.
9. If Tier-3 WARNINGs remain (`STE-PRONOUN-AMBIG`, `STE-TOPIC-SENTENCE`, or advisory `STE-POS-MISMATCH`), call **`ste_suggest_semantic_review`**, judge the brief, edit, then recheck.
10. **Propose a minimal rewrite** using the brief(s). Change only what ERROR findings require (and WARNINGs when requested).
11. **Recheck** the rewrite with `ste_check_text`.
12. **Stop** only when no ERROR findings remain, **or** explicitly list unresolved findings and why they remain.
13. **Never** claim certified compliance. **Never** claim compliance from your rewrite alone without a successful recheck.
14. **Preserve** part numbers, measurements, identifiers, warnings, cautions, and safety-critical wording unless a finding requires a synonym that does not change meaning.

Canonical loop: **check → explain → suggest_rewrite → (optional semantic_review) → host rewrite → recheck**.

## MCP tools

| Tool | Use when |
|------|----------|
| `ste_check_text(text, text_type="auto", glossary=None, output="json")` | Check pasted/generated text; primary loop tool |
| `ste_check_file(path, text_type="auto", output="json")` | Check a file on disk |
| `ste_check_changed_files(globs=None, text_type="auto", glossary=None, output="json", base=None)` | Check working-tree doc changes vs `HEAD`, or vs `git merge-base HEAD <base>` |
| `ste_lookup_word(word)` | Inspect status, meaning, alternatives, inflections, rule_ref |
| `ste_explain_finding(rule_id)` | Explain a finding’s rule (title, severity, STE ref, fix hints) |
| `ste_apply_safe_fixes(text, glossary=None)` | Apply only unambiguous 1:1 synonym replacements; returns text + diff |
| `ste_suggest_rewrite(text, text_type="auto", glossary=None, max_findings=20)` | Build a host-agent rewrite brief (prompt-return; no LLM API) |
| `ste_suggest_semantic_review(text, text_type="auto", glossary=None, max_findings=20)` | Tier-3-only semantic brief (prompt-return; no LLM API) |

### spaCy model (MCP)

Check tools do **not** take a spaCy model parameter. Set `STE100_SPACY_MODEL`
in the MCP server environment before start (default `en_core_web_sm`).

### When to use `ste_suggest_rewrite`

Call it after you have ERROR (or requested WARNING) findings and before you
rewrite with your own LLM. Use `prompt` as the rewrite instructions; respect
`constraints`. Optionally inspect `safe_fix_preview` — call
`ste_apply_safe_fixes` only if you want those 1:1 synonyms applied.

### When to use `ste_suggest_semantic_review`

Call it when the check returns Tier-3 findings (especially WARNINGs for pronouns
or topic sentence). Use `prompt` for host judgment; clear POS ERRORs before
claiming done. Semantic WARNINGs alone do not make `compliant: false`.

### When to use `ste_apply_safe_fixes`

Call it **before** a manual rewrite when findings are mostly vocabulary synonyms with a single clear approved alternative. Do **not** use it for sentence splits, voice/mood changes, or ambiguous terms—rewrite those yourself, then recheck.

### Tier-2 rule IDs

| Rule ID | Meaning |
|---------|---------|
| `STE-PASSIVE` | Verbal passive in procedures (Rule 3.6) |
| `STE-IMPERATIVE` | Non-imperative procedural step (Rule 5.3) |
| `STE-VERB-FORM` | Progressive / perfect / complex verb stack (Rules 3.2 / 3.4) |
| `STE-NOUN-CLUSTER` | Multi-word noun longer than 3 words (Rule 2.1) |

### Tier-3 rule IDs

| Rule ID | Meaning |
|---------|---------|
| `STE-PRONOUN-AMBIG` | Ambiguous pronoun (`it` / `this` / `these` / `those` / `they`) |
| `STE-TOPIC-SENTENCE` | Weak description opener (topic not clear) |
| `STE-POS-MISMATCH` | Approved POS clash (`verb↔noun` / `adj↔noun`); ERROR if high-confidence |

# Result format

Unofficial tool. Not affiliated with ASD. EU TM No. 017966390.

Primary MCP/CLI output is JSON mirroring `ste100/core/schema.py`. Optional
SARIF is available via `output="sarif"` on check tools.

## Severity meanings

| Severity | Meaning | Agent action |
|----------|---------|--------------|
| `error` | Determinative Tier-1/Tier-2/Tier-3 violation (high-confidence) | **Authoritative.** Must fix or explicitly report unresolved. |
| `warning` | Likely issue; may be heuristic / lower-confidence Tier-2 or Tier-3 | Prefer fixing; may leave with rationale if unclear unless user asks to clear warnings. |
| `info` | Advisory / context | Optional; do not treat as compliance failure. |

`AnalysisResult.compliant` is `true` only when there are no ERROR-level findings (engine definition). Warnings/info alone do not make a text non-compliant in the engine’s boolean.

Tier-2 / Tier-3 findings include evidence keys: `confidence`, `parse_cue`, `text_type`, `rule_ref`. Call MCP `ste_explain_finding(rule_id)` for titles, fix hints, and STE mapping.

### Tier-2 rule IDs

| `rule_id` | STE ref | Typical scope |
|-----------|---------|---------------|
| `STE-PASSIVE` | Rule 3.6 | procedure |
| `STE-IMPERATIVE` | Rule 5.3 | procedure |
| `STE-VERB-FORM` | Rule 3.2 / 3.4 | both |
| `STE-NOUN-CLUSTER` | Rule 2.1 | both |

### Tier-3 rule IDs

| `rule_id` | STE ref | Typical scope |
|-----------|---------|---------------|
| `STE-PRONOUN-AMBIG` | STE pronoun clarity | both |
| `STE-TOPIC-SENTENCE` | STE topic sentence | description |
| `STE-POS-MISMATCH` | Rule 1.2 / 1.3 | both (ERROR if high-conf) |

`ste_suggest_semantic_review` returns Tier-3 findings only, plus a host-agent `prompt`. Semantic WARNINGs alone do not make `compliant` false.

## Finding

A single located rule violation.

| Field | Type | Description |
|-------|------|-------------|
| `rule_id` | `string` | Stable rule identifier (e.g. vocabulary or sentence rule). |
| `severity` | `"error"` \| `"warning"` \| `"info"` | See table above. |
| `message` | `string` | Human-readable explanation. |
| `start` | `int` | Inclusive UTF-8/codepoint offset into the analyzed text. |
| `end` | `int` | Exclusive offset of the flagged span. |
| `sentence` | `int` \| `null` | 0-based sentence index when known. |
| `evidence` | `object` | Rule-specific context (word, count, etc.). Default `{}`. |
| `suggestions` | `Suggestion[]` | Proposed replacements. Default `[]`. |

### Suggestion

| Field | Type | Description |
|-------|------|-------------|
| `replacement` | `string` | Proposed text for the span. |
| `confidence` | `float` | 0.0–1.0; default `0.0`. |
| `automatic` | `bool` | `true` if suitable for `ste_apply_safe_fixes`-style auto apply. Default `false`. |

### Example Finding (JSON)

```json
{
  "rule_id": "vocabulary.unapproved",
  "severity": "error",
  "message": "Word 'utilize' is not approved; prefer 'use'.",
  "start": 0,
  "end": 7,
  "sentence": 0,
  "evidence": {
    "word": "utilize",
    "status": "unapproved"
  },
  "suggestions": [
    {
      "replacement": "use",
      "confidence": 1.0,
      "automatic": true
    }
  ]
}
```

## AnalysisResult

Full check response for `ste_check_text` / `ste_check_file` when `output="json"`.

| Field | Type | Description |
|-------|------|-------------|
| `text_type` | `"auto"` \| `"procedure"` \| `"description"` | Effective classification used for the run (`auto` may be resolved by the analyzer before rules run; the returned value reflects the type applied). |
| `compliant` | `bool` | `true` if no ERROR findings. |
| `findings` | `Finding[]` | All findings; may be empty. |
| `summary` | `object` | Aggregates (counts by severity/rule). Default `{}`. |

### Example AnalysisResult (JSON)

```json
{
  "text_type": "procedure",
  "compliant": false,
  "findings": [
    {
      "rule_id": "sentence.length",
      "severity": "error",
      "message": "Procedural sentence has 24 words; maximum is 20.",
      "start": 0,
      "end": 118,
      "sentence": 0,
      "evidence": { "word_count": 24, "limit": 20 },
      "suggestions": []
    }
  ],
  "summary": {
    "error": 1,
    "warning": 0,
    "info": 0
  }
}
```

## Related schema types (not always in check output)

These models live in the same schema module; agents may see them via
`ste_lookup_word` or glossary loading, not always in `AnalysisResult`.

### DictionaryRecord (lookup)

| Field | Type |
|-------|------|
| `word` | `string` |
| `part_of_speech` | `string` |
| `status` | `WordStatus` enum string |
| `approved_meaning` | `string` \| `null` |
| `inflections` | `string[]` |
| `alternatives` | `string[]` |
| `category` | `string` \| `null` |
| `rule_ref` | `string` \| `null` |
| `examples_ste` / `examples_non_ste` | `string[]` |
| `notes` | `string` \| `null` |

`WordStatus` values: `approved`, `unapproved`, `forbidden`, `technical_noun`,
`technical_verbs`, `not_approved_technical_verb`.

### Glossary (YAML profile → engine)

| Field | Type |
|-------|------|
| `name` | `string` |
| `technical_nouns` | `GlossaryEntry[]` |
| `technical_verbs` | `GlossaryEntry[]` |
| `preferred_terms` | `map[string, string]` |

See [terminology-profiles.md](terminology-profiles.md).

## SARIF note

When `output="sarif"`, the same findings are serialized as a SARIF 2.1.0
log suitable for CI upload / code-scanning UIs.

- Each Finding maps to a SARIF `result` (`ruleId` ← `rule_id`, level from severity).
- Offsets map to a physical location on the analyzed artifact.
- Prefer JSON for the agent rewrite loop; use SARIF for tooling pipelines.

Severity → SARIF level (typical mapping):

| Severity | SARIF level |
|----------|-------------|
| `error` | `error` |
| `warning` | `warning` |
| `info` | `note` |

Exact SARIF field layout is owned by `ste100/core/serialize.py`; treat this
section as contract intent, not a second schema.

# Terminology profiles (project glossaries)

Unofficial tool. Not affiliated with ASD. EU TM No. 017966390.

Pass a glossary YAML path to `ste_check_text` / `ste_apply_safe_fixes` via the
`glossary` argument so project-specific nouns, verbs, and preferred terms are
recognized during checks and safe fixes.

The engine loads YAML into the `Glossary` model from `ste100/core/schema.py`.

## File shape

```yaml
name: <profile-name>          # required string

technical_nouns:              # optional list
  - word: <lemma>
    part_of_speech: noun      # default: noun
    status: technical_noun    # default: technical_noun
    approved_meaning: <str>   # optional
    inflections: []           # optional list of surface forms
    preferred_term: <str>     # optional canonical display form

technical_verbs:              # optional list
  - word: <lemma>
    part_of_speech: verb
    status: technical_verbs   # default for verbs when set explicitly
    approved_meaning: <str>
    inflections: []
    preferred_term: <str>

preferred_terms:              # optional map: dispreferred → preferred
  <unwanted-form>: <preferred-form>
```

### Field notes

| Key | Purpose |
|-----|---------|
| `technical_nouns` | Product/domain nouns not in (or extending) the STE dictionary. |
| `technical_verbs` | Approved technical verbs for this project. |
| `preferred_terms` | Unambiguous 1:1 renames; safe-fixes may apply these. |
| `inflections` | Plural/tense forms the engine should treat as the same entry. |
| `preferred_term` | Optional canonical spelling for that entry. |
| `approved_meaning` | Single allowed sense; agents must not invent other senses. |

Keep glossaries **minimal**. Only add terms the project truly needs. Prefer
STE approved words when they already cover the meaning.

`preferred_terms` must be **1:1 and unambiguous** (same referent, no context
branching). Ambiguous mappings belong in agent rewrite judgment, not safe-fixes.

## Worked example

File: `glossaries/landing-gear.yaml`

```yaml
# Project terminology for landing-gear maintenance manuals.
# Unofficial STE checker profile — not an ASD publication.

name: landing-gear-maintenance

technical_nouns:
  - word: torque-link
    part_of_speech: noun
    status: technical_noun
    approved_meaning: The link that connects the landing gear oleo to the axle.
    inflections:
      - torque-links
    preferred_term: torque-link

  - word: oleo
    part_of_speech: noun
    status: technical_noun
    approved_meaning: The shock absorber strut of the landing gear.
    inflections:
      - oleos

  - word: bogie
    part_of_speech: noun
    status: technical_noun
    approved_meaning: The multi-wheel truck assembly of the main landing gear.
    inflections:
      - bogies

technical_verbs:
  - word: safeties
    part_of_speech: verb
    status: technical_verbs
    approved_meaning: Installs a safety device or lock to prevent unwanted movement.
    inflections:
      - safety
      - safetied
      - safetying
    preferred_term: safety

preferred_terms:
  utilize: use
  ensure: make sure
  torque link: torque-link
  shock strut: oleo
```

### How to use with MCP

```text
ste_check_text(
  text=<manual excerpt>,
  text_type="procedure",
  glossary="glossaries/landing-gear.yaml",
  output="json",
)

ste_apply_safe_fixes(
  text=<manual excerpt>,
  glossary="glossaries/landing-gear.yaml",
)
```

### Expected effect

- `torque-link` / `oleo` / `bogie` are accepted as technical nouns (not flagged as unapproved vocabulary solely for being absent from the base dictionary).
- `utilize` → `use` and similar `preferred_terms` entries are candidates for `ste_apply_safe_fixes`.
- Agent rewrites must keep the **approved_meaning** of glossary terms and must not substitute unrelated synonyms for safety-critical nouns.

## Authoring checklist

1. One profile per product family or manual set (`name` unique and stable).
2. Lemmas lowercase unless the term is a required mixed-case identifier.
3. List needed inflections; do not rely on guessing irregular forms.
4. Put only clear synonyms in `preferred_terms`.
5. Re-run `ste_check_text` after glossary edits—do not assume compliance without a recheck.

## references/workflow.md (verbatim)

# Rewrite / recheck workflow

Unofficial tool. Not affiliated with ASD. EU TM No. 017966390.

This document expands the skill workflow. The engine is deterministic; you
(the agent) rewrite with your own LLM, then recheck via MCP.

## 0. Multi-file first pass

When the user asks about changed docs, a PR, or “what I edited locally”:

1. Call **`ste_check_changed_files`** (or CLI `ste100 check-changed`).
2. It compares the working tree to **`HEAD`** (staged + unstaged + untracked).
3. Default globs: `*.md`, `*.txt`, `*.rst`, `*.adoc` (override with `globs` / `--glob`).
4. Aggregate `compliant` is true only when every matched file has no ERROR findings.
5. Then drill into individual files with `ste_check_file` / `ste_suggest_rewrite` as needed.

Requires a git repository. If not in a repo, the tool returns a clear error.

## 1. Classify: procedure vs description

| Signal | Prefer `procedure` | Prefer `description` |
|--------|--------------------|----------------------|
| Mood | Imperative verbs, numbered steps | Declarative statements |
| Purpose | Tell the reader what to do | Explain what something is/does |
| Typical headings | Procedure, Removal, Installation, Warning | Description, Overview, Function |

If mixed, set `text_type` to the dominant type for the span you are checking, or use `auto` and accept the analyzer’s choice.

Pass the classification into `ste_check_text` / `ste_check_file` / `ste_suggest_rewrite` as `text_type`.

## 2. Sentence length limits (Tier-1)

| Text type | Max words per sentence |
|-----------|------------------------|
| Procedure | **20** |
| Description | **25** |

Count words in the English sentence the engine segments. Split long sentences; do not pack multiple instructions into one procedural sentence.

### Procedure — too long / multi-instruction

```text
Remove the cover and disconnect the cable and inspect the connector for damage.
```

Rewrite (one instruction per sentence, ≤ 20 words):

```text
Remove the cover.
Disconnect the cable.
Inspect the connector for damage.
```

### Description — too long

```text
The hydraulic pump supplies pressure to the landing gear system and also provides backup pressure to the brake system during emergency operation.
```

Rewrite (≤ 25 words each):

```text
The hydraulic pump supplies pressure to the landing gear system.
It also supplies backup pressure to the brake system during emergency operation.
```

## 2b. Tier-2 syntax (deterministic)

| Rule ID | Fix approach |
|---------|--------------|
| `STE-PASSIVE` | Rewrite procedures in active voice / imperative. Past participles used as adjectives (Rule 3.3) are not errors. |
| `STE-IMPERATIVE` | Numbered steps must be commands (`Close the valve.`). |
| `STE-VERB-FORM` | Drop progressive/perfect/modal+passive; use approved simple forms. |
| `STE-NOUN-CLUSTER` | Keep multi-word nouns to ≤ 3 words. |

Call `ste_explain_finding(rule_id)` when a finding’s meaning is unclear. ERRORs are authoritative; WARNINGs are advisory unless the user asks to clear them.

Evidence on Tier-2 findings includes `confidence`, `parse_cue`, `text_type`, and `rule_ref`.

## 2c. Tier-3 semantic (hybrid heuristics)

| Rule ID | Scope | Fix approach |
|---------|-------|--------------|
| `STE-PRONOUN-AMBIG` | both | Name the noun instead of `it` / `this` / `these` / `those` / `they` when the prior sentence has no clear antecedent or multiple candidates. |
| `STE-TOPIC-SENTENCE` | description only | Put the topic noun in the first sentence; avoid pronoun/demonstrative starts, fragments, pure coordination, and meta-comments. |
| `STE-POS-MISMATCH` | both | Use the approved dictionary part of speech (`verb↔noun` / `adj↔noun`). High-confidence clashes are ERRORs; TN/TV and unapproved words are skipped (vocab owns them). |

Default severity is WARNING. Only high-confidence approved POS clashes escalate to ERROR.

After check, if Tier-3 WARNINGs remain → call **`ste_suggest_semantic_review`** → host judgment → recheck.
POS ERRORs still go through the rewrite path and must clear before claiming done.

## 3. Check → explain → suggest_rewrite → (semantic_review) → host rewrite → recheck

```text
(optional) ste_check_changed_files   # multi-file / local changes
   ↓
classify
   ↓
ste_check_text / ste_check_file
   ↓
ERROR findings?
   ├─ no  → if Tier-3 WARNINGs → ste_suggest_semantic_review → host edit → recheck
   │         else report “no ERROR findings on recheck” (still unofficial; not certified)
   └─ yes → optional ste_explain_finding
              ↓
            optional ste_apply_safe_fixes (1:1 only) + recheck
              ↓
            ste_suggest_rewrite  → use returned prompt (host LLM; no API in MCP)
              ↓
            host produces minimal rewrite
              ↓
            (optional) ste_suggest_semantic_review for remaining Tier-3 WARNINGs
              ↓
            ste_check_text again
              ↓
            remaining ERRORs?
              ├─ no  → done
              └─ yes → repeat suggest_rewrite / rewrite / recheck
                         OR report unresolved findings
```

### Rules for each rewrite pass

1. Treat every `severity: "error"` finding as must-fix unless you cannot without changing safety meaning—then report it unresolved.
2. Prefer the finding’s `suggestions` when present and high-confidence.
3. Change the smallest span that clears the finding.
4. Do not “improve” style beyond what findings require.
5. Prefer **`ste_suggest_rewrite`** over ad-hoc prompting; follow its `constraints`.
6. Prefer **`ste_suggest_semantic_review`** for Tier-3 WARNINGs; follow its `constraints`.
7. After every rewrite (including safe-fixes), call `ste_check_text` again.
8. Never claim compliance from an unchecked rewrite.
9. Treat `warning` as advisory unless the user asks to clear warnings.

## 4. Vocabulary and glossary

- Unapproved / forbidden words → replace with approved alternatives from the finding or `ste_lookup_word`.
- Project glossary terms override or extend the dictionary when a glossary path is passed.
- Prefer glossary `preferred_terms` mappings when both forms appear.

## 5. Preserve always

Do not alter unless a finding explicitly requires a synonym that keeps the same referent:

- Part numbers, serial numbers, document IDs, software identifiers
- Numeric values and units (e.g. `5 mm`, `120 °C`)
- Warning / Caution / Note labels and safety-critical conditions
- Proper names required by the product or regulation

## 6. Stopping criteria

**Done:** recheck returns `compliant: true` or zero ERROR findings.

**Stop with report:** remaining ERRORs that you cannot clear without inventing data or changing safety meaning. List each unresolved finding (`rule_id`, span/evidence, reason).

**Forbidden:** claiming certified ASD-STE100 compliance; claiming the text is compliant because you rewrote it without a successful MCP recheck.

## 7. Example end-to-end

**Input (procedure):**

```text
Utilize a torque wrench to carefully tighten the bolts and then check them.
```

1. Classify → `procedure`
2. `ste_check_text(..., text_type="procedure")` → errors for `utilize`, sentence length / multi-instruction
3. Optional: `ste_explain_finding` / `ste_apply_safe_fixes` may yield `Use a torque wrench...` still multi-instruction
4. `ste_suggest_rewrite` → use `prompt` + `constraints`
5. Minimal rewrite:

```text
Use a torque wrench to tighten the bolts.
Then check the bolts.
```

6. `ste_check_text` on the rewrite → no ERROR findings → report rewrite + note that results are unofficial / not certified.

**Input (Tier-2 passive step):**

```text
1. The valve is closed by the operator.
```

1. Classify → `procedure`
2. Check → `STE-PASSIVE` / `STE-IMPERATIVE` ERRORs (call `ste_explain_finding` if needed)
3. `ste_suggest_rewrite` → host rewrite → `1. Close the valve.`
4. Recheck → no ERROR findings for those rules

**Input (Tier-3 ambiguous pronoun):**

```text
Remove the panel from the unit. It is damaged.
```

1. Classify → `description`
2. Check → `STE-PRONOUN-AMBIG` WARNING (`compliant` may still be true)
3. `ste_suggest_semantic_review` → host names the noun → `The panel is damaged.`
4. Recheck → no Tier-3 findings for that span
