chenxi-bot21 Cover Letters
A cover letter is an argument, not a formality: this specific evidence makes me worth interviewing for this specific role. Everything below serves that argument.
1. The evidence bank
Maintain one reusable bank of the candidate's strongest proof points, each a single sentence with a number in it, tagged by the skills it evidences (e.g. records processed, model metrics, money/time saved, tests passing). Letters are assembled from the bank — never written from vibes. New achievement → new bank entry first.
2. Structure (one page, four paragraphs)
- Hook — the single strongest result relevant to this role, stated plainly. Never open on enthusiasm, biography, or a weakness.
- Evidence — 2–3 bank items mapped to the JD's top requirements, mirroring the JD's own vocabulary honestly. Every skill claimed gets a concrete example; a skill without an example gets cut.
- Gap handling — where the JD asks for experience the candidate lacks, name the nearest transferable evidence and one honest line of intent ("early in X, eager to learn it properly"). Honesty here reads as confidence; pretending reads as risk.
- Close — why this company specifically (one researched line, not flattery) and a clear, single ask.
3. Generator pattern (agent tooling)
The drafting loop automates well: parse the JD → score evidence-bank entries against it (word-boundary tag matching — substring matching false-positives on short tags) → assemble a draft with the top evidence → insert the gap line when a required tag has no owned evidence → emit text + document formats. Test the matcher: the two real bugs found in production were a substring tag matching inside an unrelated word, and a transferability tag suppressing the gap line it should have triggered.
Generated drafts are scaffolding: the human rewrites for voice before sending, same as any outbound copy.
4. Rules that survived contact
- Research the company for one specific, checkable fact; generic praise is filler.
- Match the résumé's factual claims exactly — a letter/résumé inconsistency is a screening red flag.
- Keep every sent letter; they become templates for their track.
- Track applications in the master tracker, not in the letters folder.
