The feature is named `skip_git_hooks` everywhere else (settings, OpenAPI, TS, MDX, accessor); the local field was the only outlier dropping `_git_`.\n\n3. **Shell quoting in `parallel_branch_commit_cmd`** — the new helper interpolated `author_name`, `author_email`, and `message` directly inside literal single-quoted strings, violating the CLAUDE.md \"always use `shell_quote()`\" rule. Rewrote it to use `fabro_sandbox::shell_quote` for all three values, matching `sandbox_git.rs::git_checkpoint`'s style. Existing substring-based tests for `--no-verify` and `commit --allow-empty` continue to pass.\n\n4. **Rustfmt alignment** — `cargo fmt` re-aligned struct-field colons in `GitState` after the rename.\n\n**Verification:** `cargo check --workspace`, `cargo +nightly-2026-04-14 fmt --check --all`, `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings` all clean. `cargo nextest run -p fabro-workflow -p fabro-config -p fabro-api` passed all 1462 tests; the targeted `fabro-cli` attach/inspect tests passed 34/34.\n\n**Skipped (out of scope):**\n\n- Extracting a unified commit-command builder between `git_checkpoint` (uses `-F <file>`) and `parallel_branch_commit_cmd` (uses `-m <msg>`). Real DRY, but the two differ on enough axes (message source, exclude pathspecs, metadata trailers) that it's a separate refactor.\n- Replacing the 9-positional-arg `git_checkpoint` signature with an options struct. Predates this diff (already has `#[allow(clippy::too_many_arguments)]`); changing it would touch many call sites unrelated to the feature.\n- Switching `self.skip_git_hooks.or(other.skip_git_hooks)` to `.combine(...)` in `combine.rs`. The surrounding `impl_combine_or_option!` macro is defined as `self.or(other)`, so the two are literally identical — pure style and the file's hand-rolled impls already use `.or()`-shaped logic.\n- Hoisting `skip_git_hooks` outside the `for setup in branch_setups` loop. Efficiency agent flagged this then dismissed it as zero-cost.",

Default remains `false`, preserving current behavior. This setting does not affect Fabro workflow hooks or metadata-branch snapshots.\n\n## Key Changes\n\n- Add `skip_git_hooks: bool` to dense checkpoint settings in `fabro-types`, defaulting to `false`.\n- Add `skip_git_hooks: Option<bool>` to sparse `fabro-config::RunCheckpointLayer` so layered config can distinguish unset from explicit `false`.\n- Update checkpoint layer merging so `exclude_globs` keeps its existing replace/inherit behavior and `skip_git_hooks` uses normal override semantics.\n- Update checkpoint resolution so missing config resolves to `skip_git_hooks = false`.\n- Thread the resolved setting into run-branch checkpoint commit creation.\n- Append the hook-skipping commit option only for Fabro-managed run-branch checkpoint commits, including:\n  - normal lifecycle checkpoint commits in `sandbox_git.rs`\n  - parallel base checkpoint commits through the same helper\n  - parallel branch worktree commits in `handler/parallel.rs`\n- Update OpenAPI `RunCheckpointSettings` and regenerate the TypeScript API client so persisted run settings expose the new field.\n- Update user docs/options reference to document `skip_git_hooks`, its default, and that it does not disable Fabro `[[run.hooks]]`.\n\n## Test Plan\n\n- `fabro-config` tests:\n  - `[run.checkpoint] skip_git_hooks = true` resolves to `true`.\n  - omitted `skip_git_hooks` resolves to `false`.\n  - higher-layer `skip_git_hooks = false` overrides lower-layer `true`.\n  - `exclude_globs` merging behavior remains unchanged.\n- `fabro-workflow` tests:\n  - checkpoint commit command includes the hook-skip option when enabled.\n  - checkpoint commit command omits it when disabled.\n  - parallel branch commit command respects the setting.\n- API/client tests:\n  - `WorkflowSettings` / `RunCheckpointSettings` round-trip includes `skip_git_hooks`.\n  - OpenAPI-generated Rust and TypeScript clients reflect the new boolean field.\n- Regression:\n  - existing git checkpoint tests still pass, including metadata branch tests.\n\n## Assumptions\n\n- The setting applies to Git commit hooks for run-branch checkpoint commits; it does not change metadata-branch behavior because metadata snapshots already use `git2` and do not fire local hooks.\n- The setting does not disable Fabro lifecycle hooks under `[[run.hooks]]`.\n- Default `false` is required for backward compatibility.\n",

Default remains `false`, preserving current behavior. This setting does not affect Fabro workflow hooks or metadata-branch snapshots.\n\n## Key Changes\n\n- Add `skip_git_hooks: bool` to dense checkpoint settings in `fabro-types`, defaulting to `false`.\n- Add `skip_git_hooks: Option<bool>` to sparse `fabro-config::RunCheckpointLayer` so layered config can distinguish unset from explicit `false`.\n- Update checkpoint layer merging so `exclude_globs` keeps its existing replace/inherit behavior and `skip_git_hooks` uses normal override semantics.\n- Update checkpoint resolution so missing config resolves to `skip_git_hooks = false`.\n- Thread the resolved setting into run-branch checkpoint commit creation.\n- Append the hook-skipping commit option only for Fabro-managed run-branch checkpoint commits, including:\n  - normal lifecycle checkpoint commits in `sandbox_git.rs`\n  - parallel base checkpoint commits through the same helper\n  - parallel branch worktree commits in `handler/parallel.rs`\n- Update OpenAPI `RunCheckpointSettings` and regenerate the TypeScript API client so persisted run settings expose the new field.\n- Update user docs/options reference to document `skip_git_hooks`, its default, and that it does not disable Fabro `[[run.hooks]]`.\n\n## Test Plan\n\n- `fabro-config` tests:\n  - `[run.checkpoint] skip_git_hooks = true` resolves to `true`.\n  - omitted `skip_git_hooks` resolves to `false`.\n  - higher-layer `skip_git_hooks = false` overrides lower-layer `true`.\n  - `exclude_globs` merging behavior remains unchanged.\n- `fabro-workflow` tests:\n  - checkpoint commit command includes the hook-skip option when enabled.\n  - checkpoint commit command omits it when disabled.\n  - parallel branch commit command respects the setting.\n- API/client tests:\n  - `WorkflowSettings` / `RunCheckpointSettings` round-trip includes `skip_git_hooks`.\n  - OpenAPI-generated Rust and TypeScript clients reflect the new boolean field.\n- Regression:\n  - existing git checkpoint tests still pass, including metadata branch tests.\n\n## Assumptions\n\n- The setting applies to Git commit hooks for run-branch checkpoint commits; it does not change metadata-branch behavior because metadata snapshots already use `git2` and do not fire local hooks.\n- The setting does not disable Fabro lifecycle hooks under `[[run.hooks]]`.\n- Default `false` is required for backward compatibility.\n",
