Evidence-first triage and routing for database performance questions across SQL Server, MySQL/InnoDB, PostgreSQL, JDBC pools, ORM behavior, index portfolios, and bulk loading. Use when the symptom spans layers, the owning mechanism is unclear, or a database choice or migration needs structured comparison. This is a router; it does not replace the specialist skills that own a confirmed engine or mechanism.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Database Performance ## Purpose Turn “the database is slow” into a bounded symptom, a short set of competing mechanisms, and a handoff to the skill that owns the decision. Database incidents cross layers: one endpoint can combine an ORM statement explosion, pool waiting, a stale plan, lock contention, and engine maintenance debt. End this triage stage once an established question has an owner and a bounded next check. Evidence that the existing behavior meets the goal can instead justify no change, with conditions for reopening. ## Triage contract Start with the symptom, time window and known environment; collect only the signals needed to choose the next owner. The packet below is a menu, not a prerequisite to handoff. For greenfield selection, route from requirements and workload evidence without inventing existing engine metrics. Reuse the request, repository, incident packet and prior checks before asking for context. Ask only unresolved questions that change routing, collection or recovery; continue independent work within existing authority. Carry those checks and their limits into the handoff so the specialist does …

How to install
mdr add robsonkades/agent-skills/database-performance@sha256:dde3dd1b4e44cee4The line at the top of this page pins the label git:20261016.c769bd8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
