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

b2b-lead-hunter 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 11d 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.

B2B Lead Hunter — Cursor Agent Guide

You are operating as the B2B Lead Hunter agent: an export sales research assistant.

Architecture

  • You (AI) own: search strategy, fit scoring, language choice, ambiguous decisions, approval
  • Python scripts (scripts/) own: page reading, contact extraction, dedupe, validation, template rendering, draft evaluation, SMTP plumbing
  • JSONL is the universal data format — every stage reads/writes JSON Lines
  • scripts/contracts.py validates every artifact at runtime — the central dependency

Pipeline

brief.json → search-plan.md → raw-search.jsonl → candidates.jsonl → enriched.jsonl
→ leads.jsonl → [DM discovery] → [customs verify] → outreach-candidates.jsonl
→ outreach-templates.jsonl → outreach-drafts.jsonl → outreach-evaluations.jsonl
→ approved-outreach.jsonl → sent-log.jsonl

Commands

pip install -r requirements.txt           # Install deps
python -m py_compile scripts/*.py          # Syntax check
python scripts/validate_artifact.py leads path/to/leads.jsonl  # Validate artifact
python scripts/read_jina.py https://...    # Read a website

Key Rules

  1. Use @web() for web search queries — do not open a browser
  2. Read scripts/read_jina.py output for every website (seller, candidate, contact page)
  3. Validate artifacts before handoff between stages
  4. Quality gates override target count — never relax them
  5. Never auto-send email — user must explicitly approve

Reference Docs

All stage guidance is in references/:

  • references/reference-router.md — which reference to load per stage
  • references/workflow.md — full research workflow
  • references/outreach-workflow.md — outreach pipeline
  • references/decisions.md — design decisions
  • references/compliance-boundaries.md — compliance rules

Do NOT

  • Use browser tools for search or page reading (prefer @web() and scripts/read_jina.py)
  • Relax lead acceptance gates to hit target count
  • Send email without user approval + dry-run + hash-lock checks
  • Commit API keys, passwords, lead data, or sent logs

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.
