Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00066 | $0.01940 |
| Opus 5 | $0.00033 | $0.00970 |
| Sonnet 5 | $0.00013 | $0.00388 |
| Haiku 4.5 | $0.00007 | $0.00194 |
Grade A, and why
build-clusters 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 12d 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
The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build Clusters
Build a topical authority cluster from a seed keyword using pillar-spoke structure, coverage scoring, and interlinking plans.
What is a Topic Cluster?
A topic cluster is a group of interlinked pages that collectively cover a subject area. Google evaluates topical authority at the cluster level — ranking a single page is harder if the site has no supporting content around the topic.
Structure:
- Pillar page — comprehensive overview of the broad topic (targets head term)
- Spoke pages — focused articles covering subtopics (target body/long-tail terms)
- Internal links — every spoke links to the pillar, pillar links to all spokes, spokes cross-link to siblings
Before You Start
Gather this context (ask if not provided):
- Seed topic. The broad subject area to build authority around.
- Existing content. Does the site already have pages on this topic? List them.
- Business relevance. How does this topic connect to the product or service?
- Content capacity. How many pieces can the team produce per month?
Step 1: Subtopic Discovery
From the seed topic, generate subtopics using these methods:
Search-derived:
- People Also Ask questions for the seed keyword
- Related searches at the bottom of SERPs
- Autocomplete suggestions (seed + a, b, c...)
- Competitor content analysis — what subtopics do top-ranking sites cover?
Intent-derived:
- Awareness: "what is [topic]", "why [topic] matters"
- Consideration: "best [topic] tools", "[topic] vs [alternative]"
- Implementation: "how to [topic]", "[topic] tutorial"
- Troubleshooting: "[topic] not working", "common [topic] mistakes"
Audience-derived:
- Beginner questions about the topic
- Advanced practitioner concerns
- Decision-maker evaluation criteria
Aim for 8-20 subtopics per cluster.
Step 2: Cluster Map
Organize subtopics into a structured cluster:
Pillar: [Broad Topic] (head term)
│
├── Spoke: [Subtopic 1] (body term)
│ └── Intent: informational
│
├── Spoke: [Subtopic 2] (body term)
│ └── Intent: commercial investigation
│
├── Spoke: [Subtopic 3] (long-tail)
│ └── Intent: transactional
│
├── Spoke: [Subtopic 4] (long-tail)
│ └── Intent: informational
│
└── ... (8-15 more spokes)
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.

build-clusters is a skill published in the GitHub repository calm-north/seojuice-skills (21 stars, last pushed 6mo ago), licensed MIT. It adds 66 tokens to every session and 1,940 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
