49-52: 🚀 Performance & Scalability | 🔵 TrivialConsider the CI cost of the fixture on every matching pull request.
generateWorkspacewrites 1500 dependency files of 60 lines each, then runsgit add .andgit commit. The Windows workflow triggers on any change underpackages/tools/src/tools/ast-edit/**. Onwindows-latest, synchronous file creation plus a full Git index build for that tree is slow, and the child run allows up to 180 s on top of it.If the job proves slow or flaky, reduce
DEP_FILE_COUNTuntil the ceiling still separates bounded from unbounded behavior, or move the workflow to a nightly schedule withworkflow_dispatch.Also applies to: 204-206

199-202: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winOptional: make the Git shim log unambiguous.
The shim logs
"$*", which joins all arguments with a single space.stripGitDirPrefixthen removes exactly two tokens. If the temporary workspace path ever contains a space, the-Cvalue spans more than one token and the stripped line keeps a path fragment. ThestartsWith('remote ')andstartsWith('branch ')assertions then pass even for a real regression, so the canary fails open.Log the subcommand directly instead of reconstructing it in the parent.
♻️ Proposed change

CodeRabbit disposition: the review produced no actionable threads. I also evaluated its generic Docstring Coverage warning and am not adding boilerplate solely to reach the external 80% metric. The repository lint/type checks do not require that metric, the new public and non-obvious boundaries already have explanatory comments, and the remaining internal helpers are described by strict types and behavioral tests. Additional restatement comments would reduce signal rather than improve maintainability. |

TLDR
Prevents ast_read_file from launching repository-wide native relationship scans whose results it never returned, and bounds the Git working-set context it does use. The read path now has finite candidate, source-byte, declaration, and concurrency budgets; propagates cancellation through discovery and acquisition; reports partial context accurately; and preserves ast_edit relationship behavior and the public ast_read_file result shape.
Dive Deeper
The prior read path could start up to five concurrent native findInFiles traversals. Its timeout did not cancel those traversals, so work could continue after the tool returned and overlap later calls. This change makes repository relationship collection an explicit enhanced-context option: ast_read_file disables it, while ast_edit retains the existing default because its preview consumes that data.
Working-set context is now acquired through bounded, deterministic stages:
The regression coverage uses the real AST read tool in a child process, records a post-result quiet window, checks RSS against a 768 MiB ceiling, and includes a POSIX Git PATH canary that fails if read wiring re-enables repository metadata commands. Calibration against the old wiring reached 2,584,936,448 bytes peak RSS; fixed wiring remained below 300 MiB. A narrow Windows workflow runs the same safe memory regression, while normal tools CI supplies non-Windows coverage.
Review notes: DeepThinker review completed and was remediated. Open Code Review exited successfully and all 29 reported findings were source-checked and remediated, but its internal result was partial: 11 of 13 selected files completed and wrapper coverage was unknown. Its result metadata reported provider zai-anthropic with model glm-5.2, session events recorded glm-5.3, and wrapper policy expected StepFun step-3.7-flash; no review configuration was changed or retried.
Local verification completed:
The full repository test command completed with environment/load failures outside this patch: the local PowerShell grammar was unavailable, ripgrep resolution observed the installed Homebrew binary despite test stubs, and five agents tests timed out under concurrent load. The five agents files all passed immediately when rerun sequentially. CI is the authoritative clean-environment run for the remaining environment-specific cases.
Reviewer Test Plan
Run the focused AST and size-gate suites:
Run the real child-process regression directly:
Inspect a Git workspace with modified TypeScript files through ast_read_file. Confirm target content, declarations, relevant snippets, and bounded working-set context remain present.
Exercise a working set beyond a limit or abort an invocation. Confirm the model content reports a concise partial reason and accounting, and that no child/native work remains after completion.
Preview an ast_edit operation and confirm repository and related-symbol context remains available.
