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-writer 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 11d 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.

LinkedIn Writer

Purpose

Generate 2 viral LinkedIn posts in different proven formats, matched to the founder's voice, using battle-tested templates and patterns that drive engagement on LinkedIn.


Execution Logic

Check $ARGUMENTS first to determine execution mode:

If $ARGUMENTS is empty or not provided:

Respond with: "linkedin-writer loaded, proceed with your topic or idea"

Then wait for the user to provide their requirements in the next message.

If $ARGUMENTS contains content:

Proceed immediately to Task Execution (skip the "loaded" message).


Task Execution

When user requirements are available (either from initial $ARGUMENTS or follow-up message):

1. MANDATORY: Read Reference Files FIRST

BLOCKING REQUIREMENT — DO NOT SKIP THIS STEP

Before doing ANYTHING else, you MUST use the Read tool to read ALL reference files. This is non-negotiable:

Read: ./references/linkedin-formats.md
Read: ./references/linkedin-posts.md

What you will find:

  • linkedin-formats.md: 7 proven LinkedIn post formats with structure templates, psychology, rules, and when-to-use matching logic
  • linkedin-posts.md: 8+ proven viral LinkedIn posts organized by format type — the example and voice library

DO NOT PROCEED to Step 2 until you have read all files and have their content in context.

2. Check for Business Context

Check if FOUNDER_CONTEXT.md exists in the project root.

  • If it exists: Read it and use the business context to personalize output (industry terminology, audience pain points, brand voice, company name, products, achievements).
  • If it doesn't exist: Proceed using defaults from "Defaults & Assumptions."

3. Analyze Input & Auto-Select Formats

From the user's requirements, extract:

  • Topic/idea — What they want to post about
  • Goal — What they want the post to achieve (engagement, authority, leads, thought leadership)
  • Any specific format preference — If they mentioned a format type

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.
