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 | $0.00097 | $0.01836 |
| Opus 5 | $0.00048 | $0.00918 |
| Sonnet 5 | $0.00019 | $0.00367 |
| Haiku 4.5 | $0.00010 | $0.00184 |
Grade A, and why
graph-schema 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 5d 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
dot-skills Graph Database Schema Design Best Practices
Comprehensive graph database data modeling guide for property graphs (Neo4j, Memgraph, Amazon Neptune, etc.). Contains 46 rules across 8 categories, prioritized by modeling impact from critical (entity classification, relationship design) to incremental (scale and evolution). Each rule includes detailed explanations, real-world Cypher examples comparing incorrect vs. correct models, and specific impact descriptions.
Philosophy: Data modeling correctness first, performance second. Always ask "what is the user trying to achieve?" before choosing structure.
When to Apply
Reference these guidelines when:
- Designing a new graph database schema from domain requirements
- Translating a relational schema to a graph model
- Deciding whether something should be a node, relationship, or property
- Reviewing an existing graph schema for modeling errors
- Refactoring a graph that produces awkward or slow queries
- Planning for schema evolution and data growth
Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| 1 | Entity Classification | CRITICAL | entity- |
| 2 | Relationship Design | CRITICAL | rel- |
| 3 | Property Placement | HIGH | prop- |
| 4 | Query-Driven Refinement | HIGH | query- |
| 5 | Structural Patterns | HIGH | pattern- |
| 6 | Anti-Patterns | MEDIUM | anti- |
| 7 | Constraints & Integrity | MEDIUM | constraint- |
| 8 | Scale & Evolution | LOW-MEDIUM | scale- |

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.
- 5d ago First seen · 121 lines · 97 tokens per session scan A 0bc70f959a9f
graph-schema is a skill published in the GitHub repository pproenca/dot-skills (205 stars, last pushed 24d ago), licensed MIT. It adds 97 tokens to every session and 1,836 once invoked, about $0.0005 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 2026-09-03.
