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

follow-up 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.

Write Follow-Up Email

Generate a follow-up email that re-engages prospects who didn't respond.

Input

Parse $ARGUMENTS for:

  • Original email or context of first outreach
  • Days since last email: How long ago was it sent
  • Follow-up number: Is this #1, #2, or #3?
  • New context (optional): News, trigger events, new value to offer

If original context is missing, ask for the key points from the first email.

Strategy by Follow-Up Number

Follow-up #1 (3-5 days after)

  • Assume they're busy, not uninterested
  • Add new value or angle
  • Keep it shorter than original

Follow-up #2 (7-10 days after)

  • Try a different approach
  • Share a relevant insight or resource
  • Reframe the value prop

Follow-up #3 (14+ days after)

  • "Break-up" email or permission-based close
  • Give them an easy out
  • Last attempt before moving on

Frameworks

The Bump

  • Quick, friendly nudge
  • "Floating this back up" energy
  • Best for follow-up #1

The Value-Add

  • Share something useful (article, insight, idea)
  • Shows you're thinking about their problems
  • Best for follow-up #2

The Breakup

  • "Should I close your file?"
  • Creates urgency without pressure
  • Best for follow-up #3

Hard Rules

  1. Shorter than original - Each follow-up gets shorter
  2. New angle: Don't just repeat the first email
  3. No guilt trips: "I haven't heard back" sounds needy
  4. No "just checking in": Empty phrase, add value instead
  5. Reference original: Brief callback to first email
  6. One CTA: Same or simplified ask
  7. 30-75 words max: Follow-ups should be scannable

What NOT to Write

  • "I wanted to follow up on my last email" (weak opener)
  • "I'm sure you're busy but..." (apologetic)
  • Resending the exact same email
  • Being passive-aggressive about no response
  • Multiple CTAs or new complex asks

Output Format

Subject: Re: [original subject] or [new short subject]

[Email body]

[First name]

Framework used: [which one] What's different: [how this differs from original] Word count: [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.
