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-calendar 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 9d 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.

Blog Calendar: Editorial Planning

Generates editorial calendars with topic clusters, publishing cadence, freshness update schedules, content decay detection, template recommendations, distribution planning, and seasonal hooks. Optimized for building topical authority (Google) and maintaining citation freshness (AI platforms).

Cross-reference

This skill operates at the FLOW Find stage. Before selecting topics, run /blog flow find for keyword discovery, content prioritization, and audience avatar prompts that should inform cluster selection and topic sequencing.

Workflow

Step 1: Understand the Blog

Gather context:

  1. Niche/industry: What is the blog about?
  2. Existing content: Scan for existing blog posts (Glob for *.md, *.mdx, *.html)
  3. Publishing cadence: How often can they publish? (default: 2x/week)
  4. Timeframe: Monthly or quarterly calendar?
  5. Business goals: What should the blog drive? (traffic, leads, authority)

Step 2: Topic Cluster Design

Design 3-5 topic clusters (pillar + supporting content):

Cluster: [Pillar Topic]
├── Pillar Page: [Comprehensive guide - 3,000+ words]
├── Supporting: [Subtopic 1 - 2,000 words]
├── Supporting: [Subtopic 2 - 2,000 words]
├── Supporting: [Subtopic 3 - 1,500 words]
├── Comparison: [X vs Y - 1,500 words]
└── FAQ: [Common questions - 1,500 words]

Each cluster should:

  • Target a primary keyword theme
  • Cover the topic comprehensively for topical authority
  • Include varied content types (guides, comparisons, how-tos, listicles)
  • Support internal linking between cluster pages

Step 2.5: Content Decay Detection

Scan existing blog posts for lastUpdated or date fields in frontmatter. Classify each post by staleness using these thresholds:

Traffic Level Stale Threshold At-Risk Threshold
High-traffic posts >30 days since update >90 days
Medium-traffic posts >90 days since update >180 days
Low-traffic posts >180 days since update >365 days

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.
