- Removed duplicate `get_pr_number` import and moved/corrected its singleton responsibility.
- Used direct, local variable access rather than repeatedly referencing imported modules.
- Used `os.environ[]` instead of `os.environ.get` for critical env lookups in a try-block (avoids lookup cost when you know failure will land in except anyway).
- Used direct file open for reading (avoiding Path overhead).
- Avoided reading/parsing JSON and dictionary keys if the PR number/env is missing.
- Reduced exception handling scope to only JSON/file-related operations.

All existing comments are preserved except where the code was made more efficient.



**Key points:**
- File reading is done only if both env vars are present, before JSON parsing.
- The exception only wraps file I/O + JSON parsing, not the env checks, so it's tighter/faster in normal runs.
- No `Path`. Used built-in open for speed.
- Early returns for failures, so the function does the minimum work necessary.
- Single access to environment variables (no redundancy).

**Functional output is preserved.**
