IELTS Writing Task 1 examiner — evaluates, corrects, and rephrases Academic or General Training Task 1 essays. Use when the user pastes an IELTS Writing Task 1 question and their essay and wants: (1) band scores on each official criterion (TA, CC, LR, GRA) plus an overall band score, (2) inline Markdown corrections on the original essay (strikethrough errors, inline code for corrections), (3) detailed correction analysis, and (4) a Band 7–9 model paraphrase with analysis. Triggers on phrases like "批改 Task 1", "evaluate my IELTS writing", "IELTS Task 1 correction", or any submission of an IELTS Task 1 prompt + essay.
Read these files before evaluating:
Execute all five sections in order and write them to a Markdown file.
Create a file in the current working directory (where the user ran Claude Code, i.e., $PWD) named:
IELTS-Writing-Task1-YYYYMMDD.md
Use today's date. Write all sections below into this file.
Score each criterion independently using the band descriptors. Scores are in whole or half bands (e.g. 6.0, 6.5, 7.0).
## Band Scores
| Criterion | Band |
|------------------------------|------|
| Task Achievement (TA) | X.X |
| Coherence & Cohesion (CC) | X.X |
| Lexical Resource (LR) | X.X |
| Grammatical Range & Accuracy | X.X |
| **Overall** | **X.X** |
Overall = average of the four criteria, rounded to nearest 0.5.
For each criterion, write 1–2 sentences justifying the score.
Reproduce the user's original essay verbatim, applying inline Markdown corrections only:
~~wrong phrase~~ correct phrase — for errors that need replacement (strikethrough the wrong, inline code the correct)`inserted word` — for missing words that need to be inserted (no strikethrough needed)Correction format example:
I think skill stacking is a necessary ability for people in this generation. Because of
thefast development of technology, some skills people learnedin least yearlast yearmaybe have been outdated todaymay already be outdated today.
Do not rewrite the essay. Only mark errors inline using the above Markdown syntax.
Provide a detailed breakdown organised by criterion:
For each error identified in the corrected essay, explain why it is wrong and what the correct form should be.
Write a model answer that:

## Band 7–9 Model Answer
Bolding convention: Bold the exact word or phrase as it appears in the model answer. If a grammar structure spans a full sentence (e.g., a mid-sentence adverbial), bold the whole sentence. Ensure every item that appears in the Section 5 vocabulary table or grammar table is bolded in the model answer.
Analyse the model answer to help the user learn from it. Use exactly these four subsections in this order:
### High-Band VocabularyA table with three columns: Model answer phrase | User's version | Why it is stronger
### Structural ChoicesNumbered list explaining how the model is organised — overview placement, data grouping strategy, paragraph sequencing, and how the model's structure improves on the user's.
### Grammar Structures That Elevate the ResponseA table with three columns: Structure | Example from model | Effect
### Key Differences from Your EssayA table with three columns: Your essay | Model answer | Why the model is stronger
