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.

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 | $0.00021 | $0.00663 |
| Opus 5 | $0.00010 | $0.00331 |
| Sonnet 5 | $0.00004 | $0.00133 |
| Haiku 4.5 | $0.00002 | $0.00066 |
Grade A, and why
explain-nexus 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.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Explain Nexus
Provide a clear, concise explanation of what Nexus is and how to use it.
Purpose
Help users understand Nexus quickly without reading extensive documentation. Covers the core concepts, key commands, and how to get started.
Time Estimate: 2-3 minutes to explain
Workflow
Step 1: Load Overview Files
Read both overview files for accurate information:
00-system/documentation/product-overview.md
00-system/documentation/framework-overview.md
Use product-overview for the "what" and framework-overview for the "how".
Step 2: Explain Core Concepts
Present this concise explanation:
# What is Nexus?
Nexus is your **AI-powered work operating system**. It gives Claude:
1. **Memory** - Your goals, preferences, and learnings persist across sessions
2. **Builds** - Structured work with planning, tasks, and progress tracking
3. **Skills** - Reusable workflows you can trigger with simple phrases
## The Magic
Every session, Claude automatically loads your context. No more re-explaining
who you are or what you're working on.
## Key Commands
| Say This | What Happens |
|----------|--------------|
| "create build" | Start a new build with guided planning |
| "continue [name]" | Resume work on a build |
| "setup goals" | Personalize Nexus with your role and goals |
| "list skills" | See all available skills |
| "done" | Save progress and end session |
## The Decision Rule
- **Builds** = Finite work (has an end)
- **Skills** = Repeating workflows (used again)
Creating "report-jan", "report-feb"? That's a SKILL, not builds!
## Quick Start
1. Say "create build" to start working
2. Say "setup goals" to personalize (optional but recommended)
3. Open a NEW chat for your next topic
Step 3: Offer Next Steps
Based on user's current state (from startup stats):
If goals not personalized:
Want to personalize? Say "setup goals" to teach Nexus about your role and objectives.
If no builds exist:
Ready to start? Say "create build" and I'll guide you through planning.
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.

explain-nexus is a skill published in the GitHub repository DorianSchlede/nexus-template (8 stars, last pushed 7mo ago), licensed MIT.
