What it does

Ink Cluster is an agent skill from jeremylongshore/tons-of-skills-marketplace. Topic cluster architecture builder — takes a core topic and maps the full cluster with 1 pillar page, 6-10 supporting posts, internal linking map, keyword targets, and estimated monthly search volume per piece. Use when asked to "build a content cluster", "map our SEO cluster for [topic]", "create a topic cluster", or "what should our pillar page be about".

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering Content strategy, On-page SEO and Keyword research. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Asked to build a content cluster
  • Map our SEO cluster for [topic]
  • Create a topic cluster
  • What should our pillar page be about

Example prompts

  • “build a content cluster”
  • “map our SEO cluster for [topic]”
  • “create a topic cluster”
  • “/ink-cluster”

Requirements

  • Pre-approved tools (allowed-tools): Read, Bash, Glob, Grep, AskUserQuestion

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Gather Cluster Context
  2. Define the Pillar Page
  3. Map the Supporting Posts
  4. Internal Linking Map
  5. Publishing Sequence
  6. Cluster Health Metrics

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash
    • Glob
    • Grep
    • AskUserQuestion

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ink Cluster loads about 1.3k tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 375 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~93
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Bash, Glob, Grep, AskUserQuestion

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:

bash
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
## Cluster Map — [Core Topic]

### Pillar: [Title]
Keyword: [keyword] | MSV: [X/mo] | Intent: Informational | WC: 3,000+

Supporting Posts:

| # | Title | Target Keyword | MSV | Intent | Word Count | Priority |
|---|-------|---------------|-----|--------|------------|----------|
| 1 | [title] | [keyword] | [X] | How-to | 1,200-1,500 | HIGH |
| 2 | [title] | [keyword] | [X] | Comparison | 1,500-2,000 | HIGH |
| 3 | [title] | [keyword] | [X] | Listicle | 1,000-1,500 | MEDIUM |
| 4 | [title] | [keyword] | [X] | Definition | 800-1,200 | MEDIUM |
| 5 | [title] | [keyword] | [X] | Case study | 1,200-1,800 | HIGH |
| 6 | [title] | [keyword] | [X] | How-to | 1,000-1,500 | LOW |
| 7 | [title] | [keyword] | [X] | Comparison | 1,500-2,000 | MEDIUM |
| 8 | [title] | [keyword] | [X] | How-to | 1,000-1,200 | LOW |
Step 3: Internal Linking Map

Every piece must link to the pillar. Supporting posts link to each other when topically adjacent.

## Internal Linking Map

Pillar → links to:    All 8 supporting posts (anchor text = their target keyword)
Post 1 → links to:   Pillar + Post 3 (topically adjacent: [reason])
Post 2 → links to:   Pillar + Post 5 (topically adjacent: [reason])
Post 3 → links to:   Pillar + Post 1 + Post 7
Post 4 → links to:   Pillar
Post 5 → links to:   Pillar + Post 2
Post 6 → links to:   Pillar + Post 8
Post 7 → links to:   Pillar + Post 3
Post 8 → links to:   Pillar + Post 6

Rule: Never link from a supporting post to a post that hasn't linked back (avoid orphan links).

Step 4: Publishing Sequence

Priority order for production and publishing:

  1. Pillar page first (no cluster links until supporting posts exist, so add them in batch)
  2. 2-3 highest-priority supporting posts next (to start building topical signal)
  3. Remaining posts in priority order
  4. Once 4+ posts exist, update pillar with all internal links in one edit

Suggested cadence: 1 post per week = full cluster live in 9 weeks.

Step 5: Cluster Health Metrics

Track these once the cluster is live:

MetricTargetCheck cadence
Pillar page impressions (GSC)Growing MoMMonthly
Supporting post rankingsEach in top 20 for target keywordQuarterly
Cluster internal link clicks>5% CTR from pillar to postsMonthly
Avg time on pillar page>3 minMonthly
Cluster-attributed leads or signups[N / month]Monthly

Delivery

Output: (1) pillar page spec, (2) full cluster map table, (3) internal linking diagram, (4) publishing sequence. If output exceeds 40 lines, delegate to /atlas-report.
