quick now auto-mark newly added failing tests. only regressions are remained failing.
Before step 3, let's add review the failing tests and analyze If that's justified to mark failure or not.
Lots of them will be better to report issue or worth to try fix them; otherwise upgrade the dependency lib first.

I'm dogfooding this command, and as your suggestion, it fixes a failed test automatically!

(Other tests (snippets) seem to fail but anyway 😅)

Great, it is good as long as it doesn't blindly mark everything expectedFailure

⚠️ Potential issue | 🔴 Critical

Add missing deps subcommand to allowed-tools.

The workflow in step 3 (line 54) uses cargo run --release -- scripts/update_lib deps, but the allowed-tools header only permits quick and auto-mark subcommands. This will cause the command to be blocked during execution.

 ---
-allowed-tools: Bash(git add:*), Bash(git commit:*), Bash(python3 scripts/update_lib quick:*), Bash(python3 scripts/update_lib auto-mark:*)
+allowed-tools: Bash(git add:*), Bash(git commit:*), Bash(python3 scripts/update_lib quick:*), Bash(python3 scripts/update_lib auto-mark:*), Bash(cargo run:*)
 ---

Note: This allows cargo run for both the deps command (line 54) and the test execution commands (lines 59, 63).

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In @.claude/commands/upgrade-pylib.md around lines 1 - 3, The allowed-tools
header currently permits only Bash(git add:*), Bash(git commit:*), Bash(python3
scripts/update_lib quick:*), and Bash(python3 scripts/update_lib auto-mark:*),
but the workflow runs cargo run --release -- scripts/update_lib deps; update the
allowed-tools header to also include Bash(python3 scripts/update_lib deps:*) (or
the equivalent pattern used for quick/auto-mark) so the `deps` subcommand is
allowed; ensure the new entry matches the existing pattern for `quick` and
`auto-mark` to permit the deps invocation and related test commands.

⚠️ Potential issue | 🟡 Minor

Add language identifiers to code blocks in step 3.

Multiple code blocks in the test failure investigation step are missing language specifications, which reduces readability and prevents syntax highlighting.

 3. **Investigate test failures with subagent**
    - First, get dependent tests using the deps command:
-     ```
+     ```bash
      cargo run --release -- scripts/update_lib deps $ARGUMENTS
      ```
    - Look for the line `- [ ] $ARGUMENTS: test_xxx test_yyy ...` to get the direct dependent tests
    - Run those tests to collect failures:
-     ```
+     ```bash
      cargo run --release -- -m test test_xxx test_yyy ... 2>&1 | grep -E "^(FAIL|ERROR):"
      ```
    - For example, if deps output shows `- [ ] linecache: test_bdb test_inspect test_linecache test_traceback test_zipimport`, run:
-     ```
+     ```bash
      cargo run --release -- -m test test_bdb test_inspect test_linecache test_traceback test_zipimport 2>&1 | grep -E "^(FAIL|ERROR):"
      ```

code blocks lack language identifiers; update the code fences around the shell

(or ```sh) for the three examples containing the commands `cargo run --release
-- scripts/update_lib deps $ARGUMENTS`, `cargo run --release -- -m test test_xxx

⚠️ Potential issue | 🟡 Minor

Add language identifier to example usage code block.

The example usage code block is missing a language specification.

 ## Example Usage
-```
+```bash
 # Using module names (recommended)
 /upgrade-pylib inspect
 /upgrade-pylib json
 /upgrade-pylib asyncio
 
 # Using library paths (alternative)
 /upgrade-pylib cpython/Lib/inspect.py
 /upgrade-pylib cpython/Lib/json/
