A reference collection for Oracle Database work, including SQL, PL/SQL, administration, application development, security, performance, migrations, and related tools. Oracle Database is software for storing and querying structured application data.

Use it to write, explain, debug, format, review, or tune SQL and PL/SQL, and to work with Oracle administration, ORDS, SQLcl, JDBC, Liquibase, migrations, and security.

It gives the agent a route to the relevant guidance instead of treating every database task the same. It also covers safe database changes and agent workflows.

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.

Origin original No closer match found in the catalogue.

Token cost

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	$0.00156	$0.01049
Opus 5	$0.00078	$0.00524
Sonnet 5	$0.00031	$0.00210
Haiku 4.5	$0.00016	$0.00105

Measured 8d ago against content hash e5ec03fbc326, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-08, from the pricing page.

Security

Grade A, and why

db 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 8d 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.

What ships with it

60 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.

Changes

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.

db is a skill published in the GitHub repository maxime-tremblay/APEXLang-Project-Template (2 stars, last pushed 3mo ago), licensed MIT. It adds 156 tokens to every session and 1,049 once invoked, about $0.0008 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 2026-08-31.
