aws-benchmark
gburd/nix-config
Run performance benchmarks on AWS EC2 (bare-metal or regular instances) with a reproducible launch → tune → measure → terminate workflow. Use for ANY AWS benchmarking — CPU/memory/IO/database/application, NUMA-related or not: choosing + launching an instance, one-time key-pair/security-group setup, OS kernel tuning (hugepages, governor, THP, NUMA balancing), EBS provisioning, A/B methodology, collecting results, and (critically) terminating the instance when done so it stops costing money. Triggers on: "benchmark on AWS/EC2", "bare-metal EC2", "launch an instance to test", "A/B benchmark", "clock sweep / NUMA benchmark", "pgbench/HammerDB on EC2". For the PostgreSQL-buffer-manager clock-sweep specifics, this pairs with the pg-numa-benchmark skill (which uses this one for the AWS substrate).
pg-numa-benchmark
gburd/nix-config
Run PostgreSQL clock sweep benchmarks on bare-metal EC2 instances. Covers AWS setup, instance launch (r8i.metal-96xl / m6i.metal), OS tuning, PG build (stock + patched), pgbench A/B testing, HammerDB TPC-C, and result collection. Use when benchmarking PostgreSQL buffer manager changes on NUMA hardware. The generic AWS benchmarking substrate (launch/tune/A-B/terminate) is in the aws-benchmark skill; this layers the PostgreSQL specifics on top.
nix-agent-configs
gburd/nix-config
Hard-won lessons for working on the Nix-managed AI agent configs in modules/home-manager/ai/ (the Bedrock-backed agents pi, claude, maki, hermes, codex, plus kiro-cli, and the LiteLLM proxy). Use this skill ONLY when editing files under modules/home-manager/ai/ or debugging agent auth/telemetry/model routing. Covers: telemetry-off enforcement, thinking-effort ceilings, the two Bedrock auth paths (bearer vs SigV4), model-reachability verification, patching pipx/venv tools, and the CI expectations for this repo. Triggers on: editing modules/home-manager/ai, "LiteLLM proxy", "Bedrock auth", "agent telemetry", "thinking effort", "kiro-cli config".
release-tagging
gburd/nix-config
Date-based release tagging conventions for this maintainer's personal repos (nix-config and other single-author repos). Use this skill ONLY when actually cutting a release or creating/pushing a git tag — the commit→push→tag→push-tag flow, the vYYYY.MM.DD[.N] format, and the deliberate maintainer exceptions to the "never push to main / never force-push" rules. Triggers on: "tag a release", "cut a release", "ship this", "create a tag", "vYYYY.MM.DD".
subagent-teams
gburd/nix-config
How to run coordinated sub-agent teams (worker → reviewer → re-reviewer) and the Bedrock model-dispatch rules for sub-agents. Use this skill ONLY when spawning/dispatching sub-agents (e.g. Pi's Agent tool, parallel task fan-out) or debugging a sub-agent that dies instantly. Triggers on: "sub-agent", "subagent", "dispatch agents", "parallel agents", "Agent tool", "sub-agent finished in <2s / 0 tool uses".
