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-posts 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 7d 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

Platforms: LinkedIn

Guides LinkedIn post copy creation and optimization. Use for generating publish-ready professional content. Suitable for copy agents and design agents (image specs).

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Output: Publish-Ready Copy

This skill enables agents to generate LinkedIn post copy optimized for engagement. Output includes character-counted text and structure for the "See more" threshold.

Post Types and Entry Points (organic)

Kind What to know
Start a post Short update; can include link preview if you paste a URL. Same feed format as other updates.
Photo Single or multiple images (carousel in feed).
Video Uploaded file (distinct from LinkedIn Live, which is live streaming and has separate gating).
Write article Article = long-form editor, separate from the short post box; long URL, better for depth and some off-site discoverability.
Document PDF / PPT / DOC (slides in feed). Official limits (check current help): on the order of ~100MB / ~300 pages per file—verify when publishing.
Poll Engagement driver; keep question and options scannable.
More (menu) Often includes celebrations, hiring-style share, Find an expert, etc. (varies by product/region).
Reshare Reshare or quote another member’s post with your take—adds context; avoid empty reshares.
Newsletter Series subscription; not the same as a one-off post but compound reach over time.
Event Create/promote events via a dedicated flow, not the same as a plain text post.

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.
