Retrieve proven SQL patterns, table cheatsheets, and join patterns from .knowledge/query-archaeology/ so past work gets reused. Fire as a pre-flight step before writing ANY SQL. Also trigger on "do we have a known query for X", "how do we usually join these tables", "have we computed this metric before". If the store is empty or missing, exit silently. Also owns the writer convention: after a validated analysis, curate the final SQL here.

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

# Skill: Query Archaeology

## Purpose
Retrieve proven SQL patterns, table cheatsheets, and join patterns from the
query archaeology store so agents reuse validated work instead of writing SQL
from scratch. The skill also defines the store's local write path: after a
validated analysis, the final SQL is curated back into the store (the Writer
Convention below), which is what makes the retrieval loop close.

## When to Use
- **Automatically** before any analysis agent writes SQL (pre-flight step)
- **Manually** when the user asks about known patterns for a table or join
- **After a validated analysis**, to curate the proven SQL (Writer Convention)

## Instructions

### Step 1: Check the Index

Read `.knowledge/query-archaeology/curated/index.yaml`. Parse counters:
`cookbook_entries`, `table_cheatsheets`, `join_patterns`.

**If all three are zero (or the file is missing), stop here.** Return nothing
and do not mention archaeology to the user.

### Step 2: Identify Search Terms

From the current analysis context, extract:
- **Table names** the agent is about to query (e.g., `orders`, `events`)
- **Query intent tags** (e.g., `funnel`, `retention`, `revenue`, `cohort`)

How to install

The exact contents, by fingerprint
mdr add ai-analyst-lab/ai-analyst/archaeology@sha256:2ced0eccef8e868f

The line at the top of this page pins the label git:20260827.7ff2e25, 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.
