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 | $0.00098 | $0.02457 |
| Opus 5 | $0.00049 | $0.01229 |
| Sonnet 5 | $0.00020 | $0.00491 |
| Haiku 4.5 | $0.00010 | $0.00246 |
Grade A, and why
nornicdb-bolt-client 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 yesterday.
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 — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NornicDB Bolt Client (Cypher API)
NornicDB exposes Bolt on port 7687 and is wire-compatible with Neo4j 5. Any upstream Bolt driver works — neo4j-go-driver/v5, neo4j-driver (Python), neo4j-javascript-driver, etc. This skill is what a client must pin to drive NornicDB safely under concurrency.
Connection
| Setting | Value |
|---|---|
| URI | bolt://<host>:7687 |
| Driver | any Neo4j 5 Bolt driver (do not vendor a NornicDB-specific fork) |
| Database name | the literal database name; address it directly via Session.Run(... database=<name>) |
| HTTP port (search REST, admin) | 7474 |
Server defaults (parsed from LoadDefaults() — these are stable):
| Field | Default | Notes |
|---|---|---|
Database.AsyncWritesEnabled |
true |
Async write-behind is on by default. Set NORNICDB_ASYNC_WRITES_ENABLED=false if you need synchronous commit so a queue can drain to a known terminal state. |
Database.PersistSearchIndexes |
false |
Search-index persistence is opt-in. Set NORNICDB_PERSIST_SEARCH_INDEXES=true if you want BM25/vector indexes to survive restart. |
Auth.Enabled |
false |
Auth is off by default. Production deployments enable via the YAML auth: field. |
Server.BoltPort |
7687 |
|
Server.HTTPPort |
7474 |
Error classes you will see
NornicDB returns Neo4j-shaped error codes (Neo.ClientError.*, Neo.TransientError.*) plus a stable message text. You can classify by either the code or the substring; the wire shape is intentionally consistent across both commit paths.
Retry these — transient
| Wire shape | Code class | When |
|---|---|---|
commit failed: conflict: node <id> changed after transaction start |
Neo.TransientError.Transaction.Outdated |
Optimistic write conflict on a node — another transaction committed first. |
commit failed: conflict: edge <id> changed after transaction start |
Neo.TransientError.Transaction.Outdated |
Same, for edges. |
commit failed: conflict: node <id> has adjacent edge <eid> changed after transaction start |
Neo.TransientError.Transaction.Outdated |
Same, propagated through an adjacent edge. |
... conflict: edge <id> changed after transaction start (statement-time, no commit failed: prefix) |
Neo.TransientError.Transaction.Outdated |
MERGE ... SET on a relationship a peer committed after your transaction began — the edge is live at latest-committed state but invisible to your snapshot. Retry on a fresh transaction converges. |
... waiting for transaction lock |
Neo.TransientError.Transaction.DeadlockDetected |
Lock contention. |
commit failed: constraint violation: ... already exists AND every statement in the group is MERGE-shaped |
Neo.ClientError.Transaction.TransactionCommitFailed |
Two writers raced on the same MERGE (n {uid:...}). See "MERGE under concurrent writers" below. |
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.
- yesterday First seen · 185 lines · 98 tokens per session scan A ee9b5daf86f5
nornicdb-bolt-client is a skill published in the GitHub repository orneryd/NornicDB (858 stars, last pushed yesterday), licensed MIT. It adds 98 tokens to every session and 2,457 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 2026-09-05.
