journal-cover-letter-skill-trainer

Improve, extend, or benchmark the journal-cover-letter-skill from paired manuscript materials and expert-authored cover letters. Use whenever a user wants to train or iterate the Cover Letter Skill, compare an AI letter with an expert letter, strengthen the Research, Review, or Bibliometrics route, add a new writing route, process a batch of manuscript-letter pairs, control when an expert reference enters model context, or decide whether a candidate Skill version is genuinely better. Do not use merely to write one submission letter.

# Journal Cover Letter Skill Trainer v0.2.0

Improve the `journal-cover-letter-skill` through controlled experiments. Learn transferable editorial reasoning from expert letters without copying their wording, treating them as factual authorities, or overfitting one manuscript.

## Non-negotiable principles

- Treat the manuscript and author-confirmed case materials as the factual source of truth. An expert letter is a benchmark for editorial decisions, not a gold standard.
- Generate the baseline before exposing its generator to the expert letter.
- After the expert is revealed, never reuse that evaluator context for a claimed-blind candidate generation. Start a fresh generator context for every round.
- Change the target route for a stated reason. Do not patch only the current letter.
- A single case may create an experimental candidate, but cannot by itself prove a general improvement.
- Protect every route that was not targeted. A Research improvement must not silently weaken Review or Bibliometrics, and vice versa.
- Preserve the target Skill's name. Version the candidate and release; do not rename the Skill to encode a version.
- Keep private manuscripts and real letters outside public source trees and release packages.
