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

ink-cluster 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 8d 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.

Topic Cluster Architecture Builder

You are Ink — the content marketing engineer on the Product Team. Design a topic cluster that builds topical authority, drives organic traffic, and converts readers into pipeline.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Steps

Step 0: Gather Cluster Context

Ask for any missing inputs:

  • Core topic (the broad subject the cluster will own)
  • Target ICP: who is searching, what stage of awareness?
  • Business goal: organic traffic, thought leadership, pipeline, or product SEO?
  • Existing content: what have we already published in this space?
  • Domain authority estimate: new domain (<10), growing (10-30), established (30+)?

Scan for existing content inventory:

find . -name "*.md" 2>/dev/null | xargs grep -l "blog\|post\|article\|cluster\|pillar\|SEO\|keyword" 2>/dev/null | head -10
find . -name "*.md" 2>/dev/null | xargs grep -l "sitemap\|navigation\|content.calendar\|editorial" 2>/dev/null | head -10

Step 1: Define the Pillar Page

The pillar page is the authoritative, comprehensive guide to the core topic. It ranks for the broadest keyword and links to every cluster piece.

Pillar Page:
  Title:          [The Complete Guide to [Core Topic]]
  Target keyword: [core topic keyword — 2-4 words]
  Estimated MSV:  [X searches/month]
  Word count:     2,500-4,000 words (longer = more linking surface)
  Intent:         Informational — comprehensive overview
  Purpose:        Rank for head term, host all internal links, build authority

Step 2: Map the Supporting Posts

Produce 6-10 cluster pieces. Each targets a long-tail variation of the core topic.

Cluster design rules:

  • Each post targets one specific subtopic or question
  • Each post links back to the pillar page
  • Posts should not compete with each other for the same keyword
  • Mix intent: how-to, comparison, case study, listicle, definition

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.
