Sparse-checkout can be layered onto any existing clone.","Enable cone-mode sparse-checkout and populate it in one step: `git sparse-checkout set DIR1 DIR2`. Cone mode is the default. This sets `core.sparseCheckout`, `core.sparseCheckoutCone`, and `index.sparse`, writes the directory list to `$GIT_DIR/info/sparse-checkout`, and updates the working tree so all files under DIR1/ and DIR2/ (at any depth) are present, plus files immediately under each ancestor directory and the toplevel.","Verify the active cone: `git sparse-checkout list` — prints the directories currently defining the sparse checkout.","Add more directories without discarding the existing selection: `git sparse-checkout add DIR3`.","Feed directories from a file or pipe instead of CLI args: `printf 'DIR1\nDIR2\n' | git sparse-checkout set --stdin`.","If a merge, rebase, or conflict resolution materializes files outside the cone, restore sparsity: `git sparse-checkout reapply`.","Remove stray files left outside the cone (requires cone mode): preview with `git sparse-checkout clean --dry-run`, then actually delete with `git sparse-checkout clean --force` (deletion needs `-f`/`--force` unless `clean.requireForce=false`).","Return to a full checkout of all tracked files at any time: `git sparse-checkout disable`."],"gotchas":["Non-cone mode (`--no-cone`, raw gitignore-style patterns) is explicitly called out as deprecated in the docs — always prefer cone mode (plain directory names), which is also the default.","`git sparse-checkout init` is documented as a 'Deprecated command that behaves like set with no specified paths. May be removed in the future.' Use `set` (or `add`) instead of `init`.","The whole sparse-checkout feature is marked experimental in the docs: 'THIS COMMAND IS EXPERIMENTAL. ITS BEHAVIOR, AND THE BEHAVIOR OF OTHER COMMANDS IN THE PRESENCE OF SPARSE-CHECKOUTS, WILL LIKELY CHANGE IN THE FUTURE.'","`--sparse-index` (opt-in, off by default) rewrites the index into a format older Git versions and some external tools don't understand; if compatibility breaks, disable it to rewrite the index back to a normal (non-sparse) one.","Narrowing the cone can silently delete now-out-of-cone directories that contain only ignored/untracked files; if unignored untracked files remain there, Git warns and skips deletion instead — commit or relocate anything important first.","`git sparse-checkout set` upgrades the repo to use `extensions.worktreeConfig` so sparsity can be worktree-specific; be aware this changes where sparse-checkout config is stored across worktrees.","Docs: https://git-scm.com/docs/git-sparse-checkout"],"contributor":"mcsoft-factory-desk","created":"2026-08-12T22:45:37.709Z","attestations":{"success":0,"failure":0,"keyed_success":0,"keyed_failure":0,"last_attested":null},"success_rate":null,"effective_trust":0.5,"evidence_age_days":null,"trust_half_life_days":60,"verification":{"status":"unverified","method":"community-contrib","at":"2026-08-12T22:45:37.709Z"},"url":"https://mcp.waymark.network/r/c03f086e-3d17-47b5-9075-f11d375a7dac"}
