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 | $0.00049 | $0.00948 |
| Opus 5 | $0.00024 | $0.00474 |
| Sonnet 5 | $0.00010 | $0.00190 |
| Haiku 4.5 | $0.00005 | $0.00095 |
Grade A, and why
public-oracle-expert-base 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.

Oracle Database Knowledge Base
Source: Compiled from Oracle official documentation, JDBC best practices, and common integration patterns.
Connection Types
| Format | Example | Status |
|---|---|---|
| Service Name | jdbc:oracle:thin:@//host:port/service_name |
Recommended |
| SID (legacy) | jdbc:oracle:thin:@host:port:SID |
Legacy, avoid |
| TNS | jdbc:oracle:thin:@tns_alias |
Enterprise with tnsnames.ora |
| EZConnect | jdbc:oracle:thin:@host:port/service_name |
Simple, no config file |
- Always prefer Service Name over SID for new projects.
- Easy Connect Plus (19c+):
jdbc:oracle:thin:@tcp://host:port/service_name?wallet_location=/path.
JDBC Driver
| Type | Description | When to use |
|---|---|---|
| Thin (Type 4) | Pure Java, no Oracle client | Default choice |
| Thick (OCI, Type 2) | Requires Oracle Client | Advanced features (TAF, Advanced Queuing) |
| UCP | Universal Connection Pool | Production pooling |
- Thin driver is sufficient for 95% of use cases.
- Use
ojdbc8.jarfor JDK 8+,ojdbc11.jarfor JDK 11+. - Add
orai18n.jarfor internationalization support.
Connection Pool
| Pool | Recommended for |
|---|---|
| UCP (Oracle) | Oracle-specific features, best performance |
| HikariCP | Spring Boot, general-purpose, simpler config |
HikariCP config for Oracle:
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@//host:1521/service_name
spring.datasource.hikari.maximum-pool-size=20
spring.datasource.hikari.connection-timeout=5000
spring.datasource.hikari.idle-timeout=300000
spring.datasource.hikari.connection-test-query=SELECT 1 FROM DUAL
LOB Handling
CLOBfor large text (>4000 chars);BLOBfor binary data.- Use
setStringForClob()/setBinaryStream()for inserts. - For reads, use
getCharacterStream()/getBinaryStream()— avoidgetString()on large CLOBs. - LOB locator vs data:
oracle.jdbc.useStreamForLobOutput=truefor streaming writes.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

public-oracle-expert-base is a skill published in the GitHub repository seed-forge/harness-ai-kit (22 stars, last pushed 10d ago), licensed Apache-2.0. It adds 49 tokens to every session and 948 once invoked, about $0.0002 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.
