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 | $0.04196 | $0.04196 |
| Opus 5 | $0.02098 | $0.02098 |
| Sonnet 5 | $0.00839 | $0.00839 |
| Haiku 4.5 | $0.00420 | $0.00420 |
Grade A, and why
neo4j-skills AGENTS.md 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 11d 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 — 436 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing Skills for this Repository
A SKILL.md is an on-demand operational playbook for an autonomous coding agent — runbook with judgment, checklist with decision logic, guardrail against improvisational mistakes.
All skills live in neo4j-*-skill/ directories. Run python3 scripts/lint_skills.py before every commit.
Language Style — Write for Agents, Not Humans
Skills are read by agents that execute instructions, not humans that interpret prose. Strip every word that doesn't add information. The Caveman compression principle: remove articles, politeness, conjunctions, and explanatory padding. Keep technical content (code, commands, tables) untouched.
❌ You should always make sure to check the schema first before writing any queries.
✅ Check schema before writing any query.
❌ The following defaults must be applied to every query that you generate.
✅ Defaults — apply every query:
❌ Don't create a new driver per request — it is important that you create one Driver
at startup and share it across goroutines for performance reasons.
✅ Create one Driver at startup; share across goroutines. Never create per-request.
Every instruction must be answerable with "done" or "not done". Terse is correct; verbose is noise that costs tokens and buries the rule.
The 500-line budget is for content, not ceremony. Frontmatter + When to Use/NOT + Entry + Checklist take ~40 lines. Spend the rest on actionable rules, decision tables, and code examples — not on explanatory paragraphs the agent doesn't need.
Six Design Principles
Every skill must satisfy all six:
| Principle | Test |
|---|---|
| Triggerable | Does the description clearly state when to activate? |
| Procedural | Do the instructions define a deterministic workflow? |
| Scoped | Does the skill do exactly one coherent thing? |
| Composable | Does it work alongside sibling skills without conflict or overlap? |
| Verifiable | Are outputs and success criteria explicit? |
| Context-efficient | Is metadata concise? Does detail load only when needed? |
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.

neo4j-skills AGENTS.md is an instructions file published in the GitHub repository neo4j-contrib/neo4j-skills (109 stars, last pushed 4d ago), licensed MIT. It adds 4,196 tokens to every session, about $0.0210 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.
