ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: The new `SUMMARIZE_CODE` template provides a logical structure for technical documentation of source code (Usage, API, Behaviors, Relationships). The update to the `SUMMARIZE` prompt to include a `<Descriptive Title>` requirement aligns with the title extraction logic used in the implementation. These changes are verified by prompt-check tests in `tests/test_summarize.py`.

### expert_build/summarize.py:cmd_summarize
VERDICT: CONCERN
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: PARTIAL
INTEGRATION: WIRED
REASONING: The expansion to support `.py` files and the logic for selecting the appropriate template based on file extension is correct. However, there is a functional mismatch: lines 81-83 provide a specific truncation warning for `.pdf` files, but the file discovery glob on line 29 only includes `*.md` and `*.py`. Consequently, the PDF warning is unreachable code. The integration with the `entry` CLI and the idempotency logic via the `.summarized` manifest appear sound and are well-supported by the new tests.

### tests/test_summarize.py
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: COVERED
INTEGRATION: WIRED
REASONING: This is a high-quality, comprehensive test suite. It covers file discovery for multiple extensions, template selection branching, truncation warnings and content capping, idempotency through the manifest file, and frontmatter stripping. The use of mocks for `invoke_sync` and `subprocess.run` ensures the tests are fast and deterministic.

VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: N/A
INTEGRATION: WIRED
REASONING: Standard boilerplate to ensure the `tests` directory is treated as a package, supporting discovery by various test runners.

### SELF_REVIEW
LIMITATIONS: I noted a discrepancy regarding PDF support in `cmd_summarize`. While I can see a `chunk_pdf.py` exists in the repository, I lack the context of the `fetch-docs` command to know if PDFs were intended to be summarized by this specific function or if the warning is simply a copy-paste artifact from a different module.

---

### FEATURE_REQUESTS
- It would be helpful to see the `subprocess` commands' help output or documentation to verify that `entry create` arguments (like `--content`) are being used correctly without relying on the implementation's own error handling.
