| name | opener-critique |
| description | Evaluates the first 1-3 sentences of a substacker draft against the writer's signature opener patterns — confession / "I hadn't done X" / reframe / small concrete admission. Classifies opener as confession | reframe | admission | news-hook | generic-opener and flags news-hook/generic as tier-1. The opener sets the voice contract for the essay. Use on every draft. Trigger keywords — opener, hook, first sentence, opening, confession opener, news hook, generic opener. |

Classifier
| Class | Markers | Voice verdict |
|---|
| confession | I hadn't, I used to think, I did not know, Until last week, I spent three hours, I was wrong about | PASS |
| reframe | X is commonly called Y — actually Z, Most people think X; actually Y | PASS |
| admission | I substitute learning for doing, I have been meaning to, I have opinions about X — the kind that feel like knowledge | PASS |
| puzzle (biology cold open) | Biological/systems question opened with a specific number or contradiction | PASS |
| epistolary | Dear friend, Dear reader, second-person address to a specific imagined reader | PASS (rare but valid) |
| news-hook | GPT-5 launched, Last week OpenAI, With the release of X, reacting to an external event | FLAG tier-1 |
| generic-opener | AI is transforming, In a world where, In today's fast-paced, As we enter a new era | FLAG tier-1 |
Workflow
Evaluate opener:
- [ ] Step 1: Extract first 1-3 sentences
- [ ] Step 2: Match against classifier marker lists
- [ ] Step 3: Assign class
- [ ] Step 4: Write one-line justification
- [ ] Step 5: If news-hook or generic-opener, produce 2 rewrite options in the confession/admission register
Worked example
Draft opener (bad): "In today's rapidly evolving AI landscape, teams face a critical choice between RAG and fine-tuning for domain knowledge."
Classification: generic-opener. Tier-1.
Rewrites:
- (a) "I spent four months trying to make a RAG demo not lie. The model was never the problem."
- (b) "I had not shipped a fine-tune until last quarter. I assumed the model was the hard part. It wasn't."
Draft opener (good): "I spent a week re-prompting a customer-service agent before I realised the agent was the wrong unit of analysis."
Classification: confession (I spent, I realised). PASS.
Draft opener (puzzle — valid): "Your immune system can recognize roughly ten trillion distinct molecular threats. It does this with a genome that contains fewer than twenty thousand protein-coding genes. The math should not work."
Classification: puzzle. PASS.
Guardrails
- First 3 sentences only. If the writer's opener is 1 sentence, use that alone.
- Never rewrite the opener beyond 2 suggested options, each ≤2 sentences.
- News-hook and generic-opener are automatic tier-1. Never soften.
- If the opener is borderline (e.g., an admission that's ALMOST generic), default to PASS and note as candidate for Editor's drift review.
- Series-log posts often open with the scoreboard or a direct match reference — that's admission-adjacent, accept.
- Epistolary register is valid but RARE. Flag if the writer uses it more than 1 in 10 posts.
Quick reference
- Input: first 3 sentences of draft.
- Output: classification + verdict (PASS / FLAG tier-1) + rewrites if flagged.
- Seven classes: confession, reframe, admission, puzzle, epistolary (all pass); news-hook, generic-opener (flag).
