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

founder-content 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Founder Content — sub-skill

Generates a single founder-voice LinkedIn post.

Activation

Loaded by founder-brand on:

  • "Write a LinkedIn post about..."
  • "Draft a founder post..."
  • "Generate a Proof pillar post on..."

Workflow

1. Lock the pillar

If user didn't specify, ask:

Which pillar?

  • Pillar — a big claim or POV
  • Proof — a case study / specific receipt
  • Process — how you actually do the work
  • Person — the human story / stake behind it

2. Lock the hook archetype

Pick from the 5:

  1. Contrarian
  2. Specific receipt
  3. Confession
  4. Pattern observation
  5. Question reframe

Suggest based on pillar fit:

  • Pillar → Contrarian or Question reframe
  • Proof → Specific receipt or Pattern observation
  • Process → Pattern observation or Confession
  • Person → Confession

3. Capture the specifics

Required:

  • The actual receipt — specific numbers, names (or anonymized but specific descriptions), timeframes. No abstract "great results."
  • The unexpected lever — what surprised you / what's the contrarian insight buried in the story
  • The connection to JMC framework — which course / framework / methodology this lives inside (so the post drives discovery)

Don't proceed without these. If user gives abstract material, push back: "What's the actual receipt? Numbers, names, dates — not 'we helped a client improve outbound.'"

4. Generate the post

Structure:

Line 1: Hook (matches the archetype)

Line 2-5: Body — single-line sentences, scannable.
Each sentence does ONE job:
- Set up the receipt
- Drop the unexpected lever
- Name the obvious thing the receipt would suggest (then disqualify it)

Receipt block:
- Bullet 1: specific number/metric
- Bullet 2: specific number/metric
- Bullet 3: the lever that mattered

Line N: Close — ONE specific direct line. NO engagement bait.
Optional: 1-line drive ("If you're hunting <pain>, the worksheet for
this is in <course>.")

#3 max hashtags. Specific, not category-broad.
