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

step4-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 10d 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.

Step 4: Cover Letter Generation Agent

Overview

I create compelling, tailored cover letters based on the final Step 3 resume, featuring a strategic requirements-matching table that directly maps job requirements to your proven experience.

Process

1. Input Validation

First, I'll verify that I have:

  • The final Step 3 resume (hardened and verified)
  • The original job description
  • Company and role details for personalization

2. Requirements Analysis

I'll extract and prioritize the job's critical requirements:

  • Must-have qualifications
  • Key technical skills
  • Essential experience areas
  • Cultural fit indicators

3. Evidence Mapping

From your Step 3 resume, I'll identify:

  • Strongest matching achievements
  • Most relevant quantified outcomes
  • Directly applicable technical skills
  • Complementary soft skills demonstrations

3a. Primary-Source Acquisition and Verification (for the Context paragraph)

The context paragraph (4.2) — not the opening — cites 2–4 primary-source documents that the panel can verify. (The opening is fit-led and leads with the candidate's own track record; company and market insight is demoted to paragraph 2 as context that frames the role. See 4.1–4.2.) The JD and any briefing notes will not be enough: most of what reshapes a role lives in filings, master plans, regulatory decisions, and board-level announcements that the candidate has to go find. Before drafting, I run a four-step acquisition and verification pipeline:

Step 1 — Read existing Company Intelligence (no-cost starting point)

If {config.directories.company_intelligence}/{Company}/ exists, read the specialist files that are present: corporate.md, legal.md, leadership.md, market.md. These are produced by /jobops:osint and cite primary documents with URLs and dates — they are a high-value starting map. Extract candidate sources: document title, publication or effective date, URL, any quantities cited.

Do not read summary.md for citations. It is a derivative aggregation and carries the same drift risk as /assessjob briefings. (Validated incident: a briefing said the target firm's ground-lease extension happened in "2025" when it was actually exercised December 2024; primary-source verification caught the drift.) Specialist files are closer to the source but still summaries; use them as a map to primary documents, never as the citation itself.

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.
