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
# TiDB Query Tuning Agent Notes Use this skill directory for two different knowledge sources: - curated topic references under `references/` - GitHub issue-derived field experience generated into markdown files ## When to mine issue experience Use GitHub issue mining when: - the local references do not cover a customer-facing symptom well enough - you need a recent field precedent instead of a general tuning rule - you want fix PRs, merge timestamps, and open issue reminders - you want to build or refresh a local corpus of planner or stats bugs, with `report/customer` issues preferred when they exist Do not start from issue mining if a stable reference under `references/` already answers the question. Use the issue corpus to complement the topic docs, not replace them. ## Default workflow 1. Start with the local references in `references/`. 2. Search `references/optimizer-oncall-experiences-redacted/` for a symptom match. 3. Search `references/tidb-customer-planner-issues/` if you need linked PRs, merge times, or still-open customer gaps. …

How to install
mdr add pingcap/agent-rules/skills/tidb-query-tuning/AGENTS.md@sha256:4191100b9a3cfeb5The line at the top of this page pins the label git:20260402.b298d60, 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.
