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

linkedin-optimization 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 6d 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

LinkedIn Optimization

Turn your LinkedIn profile into a career asset.

Profile Optimization

Headline (120 chars)

Don't just list your job title. Include:

  • Your value proposition
  • Target keywords
  • Differentiator

Bad: "Software Engineer at Acme Corp" Good: "Full-Stack Engineer | React, Node.js, TypeScript | Building products that scale"

About Section (2000 chars)

Structure: Hook → Story → Expertise → CTA

  • First 3 lines visible without clicking "see more" — make them count
  • Use bullet points for readability
  • Include results and metrics
  • End with what you're looking for

Experience

  • Write for scannability: results first, context later
  • 3-5 bullets per role with metrics
  • Use the STAR/CAR framework
  • Include media (presentations, code, design files)

Content Strategy

Post Types

Type Frequency Purpose
Educational 2x/week Share expertise
Stories 1x/week Personal connection
Opinions 1x/2 weeks Thought leadership
Engagement Daily (5 min) Comment on others' posts

Engagement Rules

  • Comment within first hour of posts for visibility
  • Add value: insights, experience, resources
  • Don't self-promote in others' comment sections
  • DM people who comment on your posts to build relationships

Networking

  • Connection request: always include a personalized note
  • Follow up within 48 hours after connecting
  • Offer value before asking for anything
  • Build relationships, not a rolodex
Changes

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.
