Pg Extension Lab
Develop, test, benchmark, and operate PostgreSQL extensions with reusable harnesses and reference protocols. Use for C/PGXS or Rust/pgrx extension work, planner hooks, CustomScan or index AM design, pg_regress/pg_isolation_regress TDD, filtered ANN/vector benchmarks, matched-recall and pages-per-query analysis, bounded parameter-space exploration, Pareto curves, hypothesis/evidence/report management, accelerator-vs-CPU crossover, resource Pareto tuning, Shape B microservice extensions, Shape C sidecar daemons, service-boundary contracts, async outbox workers, and SECURITY hardening. Balances docs, code evidence, and execution results. Includes copy-ready test, benchmark, contract, and ops assets. Not for projects without a PostgreSQL extension layer.

From the source SKILL.md
pg-extension-lab is a harness for validating a PostgreSQL extension's observable behavior in an isolated, reproducible environment, separately from its implementation — covering three architecture shapes and five reference categories. Use it not only to build an extension from scratch but to design tuning experiments, write scenarios, and run isolation/regression tests against an existing one. Start with the mental model, identify your shape, then open the category that matches the request — each category has a README.md index that links to dense, single-topic detail files (progressive…
What this skill does
Pg Extension Lab is a community-contributed Claude Code skill in the forensics sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/pg-extension-lab/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Pg Extension Lab Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 185,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Pg Extension Lab skill?
Use Pg Extension Lab when your Claude Code task falls under the Security category — specifically in the forensics area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Pg Extension Lab" or describe the task and let Claude pick). Browse related skills at
/category/security/.
What is a Claude Code skill and how does the Pg Extension Lab skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Pg Extension Lab is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category. Learn more at
