description	Use when the user needs to manage the tree-sitter parser cache — prefetch parsers for offline or CI runs, list what is downloaded, inspect a language, find the cache directory, or clean it. Covers `ts-pack download`, `list`, `info`, `cache-dir`, `clean`, and `init`.

Managing parsers

Parser libraries download on demand the first time a language is used and are cached on disk. Manage that cache explicitly for offline work, CI prefetch, reproducible builds, or to reclaim space.

Note: parser cache management (download, clean, init) is done via the ts-pack CLI directly. The OpenCode tools expose only parse/process/info.

Prefetch (offline / CI)

ts-pack download python rust typescript   # specific languages
ts-pack download --all                    # every available language
ts-pack download --groups web,systems     # by group
ts-pack download python --fresh           # clean cache first, then download

Available groups: web, systems, scripting, data, jvm, functional (comma-separated for --groups). Run download in your CI setup step so later parse/process calls hit the cache instead of the network.

Inspect

ts-pack list                 # all available languages
ts-pack list --downloaded    # only languages currently cached
ts-pack list --manifest      
ts-pack list --filter script 

ts-pack info python          
ts-pack cache-dir
