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

blog-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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (manage_examples.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Blog Writer

Overview

This skill enables writing blog posts and articles that authentically capture the writer's distinctive voice and style. It draws on examples of the writer's published work to produce content that is direct, opinionated, conversational, and grounded in practical experience. The skill includes automatic Notion integration and maintains a growing library of finalized examples.

When to Use This Skill

Trigger this skill when:

  • The user requests blog post or article writing in "my style" or "like my other posts"
  • Drafting thought leadership content on AI, productivity, marketing, or technology
  • Creating articles that need the writer's authentic voice and perspective
  • The user provides research materials, links, or notes to incorporate into writing

Core Responsibilities

  1. Follow the writer's Writing Style: Match voice, word choice, structure, and length of example posts in references/blog-examples/
  2. Incorporate Research: Review and integrate any information, research material, or links provided by the user
  3. Follow User Instructions: Adhere closely to the user's specific requests for topic, angle, and emphasis
  4. Produce Authentic Writing: Create content that reads as genuinely the writer's voice, not generic AI-generated content

Workflow

Phase 1: Gather Information

Request from the user:

  • Topic or subject matter
  • Any specific angle or thesis to explore
  • Research materials, links, or notes (if available)
  • Target length preference (default: 800-1500 words)

Review all provided materials thoroughly before beginning to write.

Phase 2: Draft the Content

Reference the style guide at references/style-guide.md and examples in references/blog-examples/ for calibration.

When writing:

  1. Start with a strong opening statement establishing the thesis
  2. Use personal voice and first-person perspective where natural
  3. Include relevant personal anecdotes or professional experience if applicable
  4. Structure with clear subheadings (###) every 2-3 paragraphs
  5. Keep paragraphs short (2-4 sentences)
  6. Weave in research materials naturally, not as block quotes
  7. End with reflection, call-to-action, or forward-looking statement

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.
