Written for no agent in particular: nothing here depends on one.

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

cold-outbound-optimizer 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 13d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/cold-outbound-sender.py, scripts/competitive-monitor.py, scripts/cross-signal-detector.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

python3 telemetry/telemetry_init.py 2>/dev/null || true

Cold Outbound Optimizer


Startup: Determine Mode

Ask the user:

  1. Do you have an existing Instantly account with campaigns to audit, or are you starting from scratch?
  2. Do you have an Instantly API key? (Required for audit mode.)

If API key provided → run scripts/instantly-audit.py to pull campaigns, account inventory, and warmup scores before proceeding.


Phase 1: Discovery & Audit

1A — Infrastructure Check (if API key available)

Run python3 scripts/instantly-audit.py --api-key <KEY> and report:

  • Active campaigns (name, status, reply rate, open rate)
  • Sending accounts (count, warmup score, daily limit)
  • Domain inventory
  • Warmup gaps: any account with score <80 or <14 days warmup → flag as NOT ready

1B — Performance Data

  • Pull campaign analytics from Instantly
  • Ask: "Do you have a spreadsheet with historical outbound data?" If yes, request link.

1C — ICP Definition

If no ICP defined, collect:

  • Titles: Who are you targeting? (e.g., VP Marketing, Head of Growth)
  • Industries: Which verticals?
  • Company size: Employee count or revenue range?
  • Revenue floor: Minimum ARR/revenue to qualify?
  • Anti-ICP: Who to explicitly exclude?

Use references/icp-template.md as the collection template.

1D — Business Context

Collect:

  • What do you sell? (One sentence, no jargon)
  • What's the primary offer? (Free trial, audit, demo, consultation)
  • Real URLs to reference (pricing page, case studies, relevant content)
  • Any proof points? (Client results, stats, social proof)

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.
