Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

write-cover-letter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

write-cover-letter

Earn the reader the next 30 seconds. Open with one concrete reason this candidate fits this role at this company. Hard rules: ../_shared/RULES.md. Use Communication / Management / Creative verbs from ../tailor-resume/reference/action-verbs.md.

Inputs

  1. Profile: profile/master-profile.md. Read context: for direction only — never quote.
  2. Job: pasted JD text, a URL (use WebFetch), or an entry from jobs/found-<date>.json. Known-info gate (RULES §6): if no job is given inline, read jobs/current.json and use its jd_text/company/role — do not re-ask for the JD when it's already captured upstream.
  3. Tone: enthusiastic | confident | concise | warm (default: confident).
  4. Optional sidecar: resumes/<slug>.tailor.json from a prior tailor-resume run — reuse its keyword list and basics_overrides.summary so the letter and the resume sing the same notes.
  5. Optional score-fit sidecar: scores/<job-id>.score.json — reuse missing_keywords to know what the resume already incorporated.

If no job is supplied and jobs/current.json is absent, ask for it; the tone has a safe default.

Method

  1. Region note. Read the target region pack:

    • US: cover letters role-dependent — stronger for senior, mission-driven, career-change roles. Surface this in the rationale so the user decides whether to send.
    • IN: cover letters less emphasized; usually a 2–3 sentence email body suffices. Offer a "short form" alternative if the user wants.

  2. Read the JD for 3–5 must-have themes, the JD's tone of voice (formal / casual / mission-led), and any explicit asks ("tell us why you want to work here").

  3. Pick two flagship achievements from the profile that map to those themes — each quantified. No invention; if the profile lacks a quantified match, pick the closest qualitative win and flag the gap rather than fabricating a number.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
