An enterprise relational database from IBM that stores structured data and is widely used on mainframes, as well as Linux, Unix, and Windows systems. It also supports data warehousing and analytics.

Use it for mainframe databases, hybrid-cloud systems, analytical workloads, and migrations from compatible relational databases.

It helps teams run and modernise large, long-running business systems, including banking and insurance applications.

db2 — Skill for Claude Code and Codex by G1Joshi

Install

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.

Any agent

npx skills add G1Joshi/Agent-Skills --skill db2

Clone the repo

git clone --depth 1 https://github.com/G1Joshi/Agent-Skills

Made for: Claude Code, Codex.

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	$0.00016	$0.00351
Opus 5	$0.00008	$0.00176
Sonnet 5	$0.00003	$0.00070
Haiku 4.5	$0.00002	$0.00035

Security

Grade A, and why

db2 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 9d 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 it actually says

IBM Db2

Db2 is a family of data management products, including the relational database. It is famous for running on Mainframes (z/OS) but also runs on Linux/Unix/Windows (LUW).

When to Use

Legacy/Mainframe: The backbone of banking and insurance legacy systems.
Hybrid Cloud: IBM's "Cloud Pak for Data" strategy makes Db2 run anywhere (OpenShift/Kubernetes).
Analytics: Db2 Warehouse (formerly BLU Acceleration) offers column-store in-memory acceleration.

Core Concepts

BLU Acceleration

Columnar storage + In-memory computing. Drastically speeds up analytics queries without complex indexes.

pureScale

Clustering technology (similar to Oracle RAC) for unlimited scalability and high availability on distributed systems.

SQL Compatibility

Db2 has good compatibility with Oracle PL/SQL, making migrations easier.

Best Practices (2025)

Do:

Use In-Database AI (2025): Use watsonx.ai integration to run ML models or Vector similiarity search directly inside DB2.
Cloud Modernization: Move to Db2 on Cloud or containerized Db2 on OpenShift for easier management.
Administration Foundation: Use the new browser-based admin tools instead of the deprecated Data Studio.

Don't:

Don't ignore maintenance: Runstats (statistics collection) is critical for the DB2 optimizer to pick the right path.

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.

db2 is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 7mo ago), licensed MIT. It adds 16 tokens to every session and 351 once invoked, about $0.0001 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.
