+# Query Languages
+
+Use jj's query languages when you need to select revisions, paths, or render compact output without falling back to the default verbose UI.
+
+**Tested with jj 0.41.0**
+
+## Revsets
+
+Use revsets to select commits and workspaces.
+
+Common selectors:
+
+- `@`: current working-copy change
+- `@-`: parent of the current working-copy change
+- `trunk()`: configured mainline; use this instead of guessing `main` vs `master`
+- `::@`: all ancestors of `@`
+- `trunk()..@`: work reachable from `@` that is not on `trunk()`
+- `working_copies()`: all workspace working-copy commits
+- `<workspace>@`: another workspace's working-copy commit
+- `<change-id>`: a stable change ID such as `wqzktpqm`
+
+Agent patterns:
+
+```bash
+# Current work relative to trunk
+jj --no-pager log -r 'trunk()..@'
+
+# All active workspace tips
+jj --no-pager log -r 'working_copies()'
+
+# One specific workspace tip
+jj --no-pager log -r '<workspace>@'
+```
+
+Quote revsets that contain punctuation or function calls.
+
+## Filesets
+
+Use filesets when a command should operate on only part of the tree.
+
+Common patterns:
+
+- `path` or `"path"`: cwd-relative path prefix
+- `file:"path"`: exact cwd-relative file path
+- `glob:"pattern"`: cwd-relative glob
+- `root:"path"`: workspace-relative path prefix
+- `~x`: everything except `x`
+- `x & y`: intersection
+- `x | y`: union
+- `x ~ y`: subtract `y` from `x`
+
+Examples:
+
+```bash
+# Only markdown files in the current directory
+jj diff 'glob:"*.md"'
+
+# Everything in src except snapshots
+jj diff 'src ~ glob:"src/**/*.snap"'
+
+# Exact file path
+jj diff 'file:"README.md"'
+```
+
+## Templates
+
+Use templates when default output is too large or too decorative for agent work.
+
+Common building blocks:
+
+- `++`: concatenate output pieces
+- `if(cond, a, b)`: conditional formatting
+- `description.first_line()`: one-line summary
+- `change_id.shortest(8)`: stable short ID
+- `bookmarks`: bookmark names for a commit
+- `current_working_copy`, `empty`, `conflict`: useful booleans in `jj log`
+
+Example:
+
+```bash
+jj --no-pager log --no-graph -n 5 -T 'change_id.shortest(8) ++ " " ++ if(description, description.first_line(), "(no description)") ++ "\n"'
+```
+
+Start from `references/TEMPLATES.md` instead of inventing new templates unless you need something substantially different.
+
+## Rules
+
+- Prefer `trunk()` over hardcoding `main` or `master`.
+- Quote revsets and filesets in shell commands when punctuation could be interpreted by the shell.
+- Prefer compact `jj --no-pager` inspection commands before widening the query.
+- If a query fails to parse, check `jj <command> --help`, `jj help -k revsets`, `jj help -k filesets`, or `jj help -k templates`.
