+## SQL
+
+`gitcrawl` does not currently expose a first-class `sql` command. For exact
+local archive counts or rankings, use SQLite read-only mode against the
+configured DB and prefer CLI commands for normal reads.
+
+Useful examples:
+
+```bash
+sqlite3 -readonly ~/.config/gitcrawl/gitcrawl.db \
+  "select count(*) as threads from threads;"
+sqlite3 -readonly ~/.config/gitcrawl/gitcrawl.db \
+  "select r.full_name, count(*) as threads from threads t join repositories r on r.id = t.repo_id group by r.full_name order by threads desc limit 20;"
+sqlite3 -readonly ~/.config/gitcrawl/gitcrawl.db \
+  "select state, count(*) as threads from threads group by state;"
+```
+
+Do not run mutating SQL against the archive. Use local maintainer commands for
+overrides instead of writing database rows directly.
+
 When the installed CLI lacks a new feature, build or run from
 `~/GIT/_Perso/gitcrawl` before concluding the feature is missing.

 - Add a repo-local `gitcrawl` agent skill for local archive, freshness, gh-shim,
   cluster, and verification workflows.
+- Document read-only SQLite query examples in the repo-local agent skill so
+  agents can do exact local archive counts without mutating state.
 - Document the crawlkit control surface now available on `main`, including
   `metadata --json`, `status --json`, and `doctor --json` for local launchers
   and CI.
