Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.00508 |
| Opus 5 | $0.00021 | $0.00254 |
| Sonnet 5 | $0.00008 | $0.00102 |
| Haiku 4.5 | $0.00004 | $0.00051 |
Grade A, and why
cold-email-4-sequence 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.
What it actually says
Cold Email 4-Sequence Framework
Standard 4-email sequence framework for cold outreach.
Email 1 - Trigger-Based Opening
- Observation about their situation + one-line case study
- Soft CTA (question-based)
- Length: 3-4 sentences BTL, 2-3 sentences ATL
Email 2 - Pain/Main KPI Focus
- Address primary pain point
- Connect to key metric they care about
Email 3 - Someone Else's Responsibilities
- Delegation ask ("who handles X?")
- Opens thread to correct person
Email 4 - Break-Up
- Timing question ("Is this not a priority right now?")
- Clean exit that leaves door open
Email Structure Checklist
Opening (trigger) + Assumption + Social proof with numbers + Open-ended question
- BTL emails: 3-4 sentences
- ATL emails: 2-3 sentences
Timing
- Email 2: Send 3 days after Email 1
- Email 3: Send 14 days later (new subject line)
- Email 4: Break-up if no response

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.
