+
+Clear cache entries.
+
+Options:
+  --packuments       Clear packument cache only
+  --partitions       Clear partition cache only
+  --checkpoints      Clear checkpoint files only
+  --registry <url>   Clear entries for specific registry origin
+  --match-origin <key>  Clear entries matching origin key (e.g., paces.exale.com~javpt)
+  --package <name>   Clear cache for specific package
+  --older-than <dur> Clear entries older than duration (e.g., 7d, 24h, 30m)
+  --dry-run          Show what would be cleared without deleting
+  --interactive      Prompt for confirmation before clearing
+
+Examples:
+  _all_docs cache clear                           # Clear everything
+  _all_docs cache clear --packuments              # Clear only packuments

+  _all_docs cache clear --checkpoints             # Clear only checkpoints
+  _all_docs cache clear --registry https://registry.npmjs.com
+  _all_docs cache clear --match-origin paces.exale.com~javpt
+  _all_docs cache clear --dry-run                 # Preview what would be cleared

-- `--type <type>` - Clear type: partition, packument, all
-- `--older-than <days>` - Only clear entries older than N days
-- `--pattern <glob>` - Clear entries matching pattern
-- `--yes` - Skip confirmation prompt

+- `--checkpoints` - Clear checkpoint files only
+- `--registry <url>` - Clear entries for specific registry origin
+- `--match-origin <key>` - Clear entries matching origin key (e.g., `custom.reg.io`)
+- `--package <name>` - Clear cache for specific package
+- `--older-than <duration>` - Clear entries older than duration (e.g., `7d`, `24h`, `30m`, `60s`)
+- `--dry-run` - Show what would be cleared without deleting
+- `--interactive`, `-i` - Prompt for confirmation before clearing

+**Duration format:**
+- `d` - days (e.g., `7d` = 7 days)
+- `h` - hours (e.g., `24h` = 24 hours)
+- `m` - minutes (e.g., `30m` = 30 minutes)
