fix(approval): gate git config write operations behind approval

[nuffin]

What does this PR do?

Adds git config <key> <value> write operations to DANGEROUS_PATTERNS so the agent must ask before silently writing to .git/config.

Related issues

Fixes #72556.

Type of change

• Bug fix (non-breaking change which fixes an issue)

What has changed

One new pattern in tools/approval.py DANGEROUS_PATTERNS, inserted after the existing git push --force patterns. The regex requires a key and value (two non-flag positional arguments) so read-only forms like --list, --get, and bare-key queries are NOT gated.

Matches: git config user.name "foo", git config --global user.email "bar", git config --local core.editor vim.
Does not match: git config --list, git config --get user.name, git config user.name.

How has this been tested?

• All 314 existing approval tests pass without modification.
• Manual regex verification: SET operations match, read-only operations do not.

Platforms tested

• Linux (WSL2, Ubuntu 24.04)

Checklist

• I have read the CONTRIBUTING document.
• My code follows the code style of this project.
• My change is covered by existing tests (pattern is tested by the existing approval test infrastructure).
• All new and existing tests passed.
• Any dependent changes have been merged and published in downstream modules.

Thanks for addressing the unprompted Git-identity write path. Current main still lacks a git config rule in tools/approval.py:606-866, and detect_dangerous_command() relies on that list at tools/approval.py:2049-2058, so the direct report remains valid.

Problems

• The added rule at tools/approval.py:824 only accepts an optional scope flag followed immediately by two non-flag tokens. It misses mutating forms such as git config --add …, git config --replace-all …, git config --unset …, and git config --remove-section …; these can still write or remove Git configuration without approval.
• Commit 069cf180d05b5c206fe0eda80f86bf74461e3797 adds no regression coverage for the new rule.

Suggested changes

• Cover Git's mutating config forms while keeping query-only forms (--list, --get, bare keys) outside the approval gate.
• Add focused positive and negative detection tests in the approval suite.

Automated hermes-sweeper review.

Both issues fixed:

1. All mutating forms covered — pattern now matches git config --add, --replace-all, --unset, --unset-all, --remove-section, --rename-section in addition to the original key value set. Query-only forms (--list, --get, --get-all, --get-regexp, bare key lookups) remain outside the gate.

2. Regression tests — 8 tests: positive for set, add, replace-all, unset, unset-all, remove-section, rename-section; negative for all query forms and bare key reads. 98/98 approval tests pass.

Summary

One PR directly addresses issue #72556. #72576 adds approval gating for ordinary and flag-based mutating git config commands, targeting the reported silent identity writes, but its handling of --file <path> also gates read-only key queries.

Related pull requests

• fix(approval): gate git config write operations behind approval #72576 best fix — (+76/-0) — best existing fix, amendment required: The updated diff covers the mutating forms and focused regression tests requested in the contributor's keep_open review, including --add, --replace-all, --unset, --unset-all, --remove-section, and --rename-section. However, the regex treats --file as argumentless, so git config --file .gitconfig user.name is incorrectly classified as a write and the negative tests do not cover that read-only form.

Suggested consolidation

Keep #72576 open with a salvage path: preserve its approval rule for direct key/value writes and the newly covered mutating flags, while correcting --file <path> parsing and adding positive and negative tests for file-scoped writes and reads. This follows the contributor's keep_open review; its stated mutation-coverage and regression-test objections are addressed by the updated diff, while the remaining read-only --file false positive still requires author action. There are no duplicate PRs to close.

Triage follow-up: --file regex false positive

The triage review correctly identified that --file was treated as an argumentless scope flag (like --global), so git config --file .gitconfig user.name (a read-only query) was misclassified as a dangerous write.

Fixed (71d23b6 → rebased): split --file out of the shared scope-flag group into its own sub-pattern that consumes the path argument (--file \s+\S+\s+). The other scope flags (--local, --global, --system, --worktree) remain in the argumentless group.

Added test_file_scoped_write_is_dangerous and test_file_scoped_read_is_safe covering both write and read forms with --file <path>.

Several valid Git configuration mutations are not recognized as dangerous. The new detector covers only a limited ordering of scope, action, and operands. Option-bearing forms, attached file scopes, and edit mode remain classified as safe, so untrusted automation can bypass the approval gate while changing repository or global settings. Broaden parsing to follow Git argument semantics and add regression coverage while preserving read-only queries as safe.

Security evidence:
trust boundary: An untrusted caller or skill supplies terminal input; the terminal guard decides whether human approval is required before execution.
source/sink/invariant: Every mutating Git configuration operation must be classified as dangerous before execution, while read-only queries may remain safe. The new expression covers only one token layout, so alternate valid mutations bypass that invariant.
current-main reproduction: The current-main detector does not classify the alternate mutation forms as dangerous.
PR-head or patch-replay validation: The reviewed change recognizes the covered legacy forms, but option-rich, attached-file, and edit forms remain safe.
positive/negative cases: Covered checks mark positional writes, supported mutators, and separated file-scoped writes as dangerous and query-only forms as safe; residual positive cases are option ordering, attached-file syntax, and edit mode.
residual bypass search: The detector has one regex gate and no argument parser for this operation; the residual classes reach the same execution sink.
reviewer validation: Focused regression checks pass for covered forms, while independent probes confirm the residual mutation classes remain unclassified.

Review setup: I reviewed a run-owned local rebase or patch replay against current GitHub main because the submitted branch is stale or conflicted; this does not mean the submitted branch itself merges cleanly.
