Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00000 | $0.01952 |
| Opus 5 | $0.00000 | $0.00976 |
| Sonnet 5 | $0.00000 | $0.00390 |
| Haiku 4.5 | $0.00000 | $0.00195 |
Grade A, and why
system 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.
How it starts
The opening of the file, as written. The whole thing — 305 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/system
Create a comprehensive System note documenting an enterprise system, application, platform, or infrastructure component with full architecture knowledge graph metadata.
Usage
/system <name>
/system <name> --type <type>
/system <name> --quick
/system SAP S/4HANA
/system DataPlatform --type platform
/system Kong API Gateway --quick
Instructions
This skill uses progressive disclosure to efficiently gather system information while providing sensible defaults.
Phase 1: Parse Input & Duplicate Check
- Extract system name from command
- Query graph index for existing systems:
node scripts/graph-query.js --type System --search "<name>" - If similar system found, show it:
- "Found: [[System - SAP S/4HANA]]. Did you mean this one?"
- Offer to open existing instead of creating duplicate
- Check for
--quickflag (skip optional phases) - Check for
--typeflag (pre-set system type)
Phase 2: Essential Information (Always Ask)
Gather required fields with defaults:
Creating System note for: <name>
1️⃣ System ID (for CMDB/integrations):
Default: <AUTO from name: SAP-S4HANA>
User input: [optional override]
2️⃣ Aliases (alternative names, acronyms):
Examples: PAD, Aerospace & Defence, A&D
→ Search System Catalog in Confluence for known aliases
→ Check LegacyEngineeringSystemF space System Catalogue
Default: []
User input: [comma-separated list]
3️⃣ APM Number (Application Portfolio Management ID):
Format: APM0001234
→ Search Confluence System Catalog (AL space) for APM number
→ Link: https://yourorg.atlassian.net/wiki/spaces/AL/
Default: null
User input: [APM number if known]
4️⃣ System Type:
- application (business application)
- platform (shared infrastructure)
- database (data store)
- middleware (integration layer)
- saas (cloud service)
- infrastructure (compute/network)
Default: application
User input: [selection]
5️⃣ Owner (person or team):
Search existing: [[Person - Name]]
Default: Current user or unassigned
User input: [name to search and link]
6️⃣ Status:
- active (in production)
- planned (not yet deployed)
- deprecated (being retired)
Default: active
User input: [selection]
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.

system is a skill published in the GitHub repository DavidROliverBA/ArchitectKB (52 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,952 tokens. 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 2026-09-03.
