7 Pillars Quality Gate

Mark each item. CI enforces these via the quality-gate.yml workflow.

1. Security

• No new secrets, tokens, or credentials in the diff (gitleaks will block)
• No new use of eval, exec, subprocess shell=True, pickle.loads on untrusted input, or arbitrary deserialization
• New dependencies (if any) reviewed for known CVEs and license compatibility
• Path traversal, command injection, and SSRF surfaces explicitly considered for any new I/O code

2. Stability

• All existing tests still pass on Linux + Windows × Python 3.11/3.12
• New behavior covered by tests; tests are deterministic (no time.sleep / network / OS-scheduler dependencies)
• Coverage does not regress (codecov gate)
• No tests were skipped, deleted, or marked xfail to make the PR pass

3. Memory leak

• Long-lived objects (orchestrator, watcher, cache) are bounded
• New caches have eviction policy (LRU, TTL, or explicit size limit)
• No new global state that grows unbounded with usage
• If you added a new module that loads heavy resources, consider lazy initialization

4. Versatility

• Works on Linux, Windows, macOS (paths, line endings, locale considered)
• Works on Python 3.11, 3.12, 3.13 (no Python-version-specific syntax without fallback)
• No hardcoded paths, locales, or encodings (use pathlib.Path, encoding="utf-8" explicit)
• If you touched a parser, all 20 supported formats still parse correctly

5. Scalability

• No O(n²) or worse algorithms on user-controlled inputs
• Benchmark impact considered (run pytest bench/ locally if you touched search/index/embed)
• If perf regression > 10% in any metric, justification provided below
• Concurrency safety: no new shared mutable state without lock or documented thread confinement

Performance impact (required if you touched mcp_server/server.py, mcp_server/ingestion.py, or bench/):

metric          before    after    delta
search p95      ___ ms    ___ ms   ___%
index docs/sec  ___       ___      ___%
RSS @ 1k docs   ___ MB    ___ MB   ___%

6. Versioning

• If this is user-facing change: bumped version in pyproject.toml, mcp_server/__init__.py, and npm/package.json atomically
• If this is a breaking change: bumped MAJOR, added migration notes in CHANGELOG, marked BREAKING CHANGE: in commit footer
• CHANGELOG updated with entry under ## Unreleased in README.md
• Public API surface (mcp_server/server.py MCP tool decorators) unchanged, OR breaking changes documented

7. Quality

• ruff check passes
• ruff format --check passes
• Type hints on new public functions (mypy --strict clean for new files)
• Docstrings on new public functions (used by interrogate)
• Cyclomatic complexity reasonable (radon cc --max=C)
• No dead code (vulture would not flag new code)
• PR is reasonably sized (< 500 lines of diff preferred; bigger PRs split or justify)

Greptile Summary

The PR adds a centered banner to the top of the project README.

• Adds an HTML image block above the project heading.
• References a local banner asset that is not included in the repository.

Confidence Score: 4/5

The missing banner asset should be added or the image path corrected before merging.

The only changed behavior renders a local image path whose target is absent from the PR head, so the new README banner will be broken.

Files Needing Attention: README.md

Important Files Changed

Filename	Overview
README.md	Adds a top-level banner whose referenced local PNG is missing, causing broken rendering.

Changes

README presentation

Layer / File(s)	Summary
Banner integration README.md	Adds a centered banner linked to ./assets/knowledge-rag-banner.png with descriptive alt text and full-width sizing.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to e7d2e

The PR adds a README banner whose referenced image is missing, so the banner will render broken. This is a localized documentation issue with no runtime impact, but the asset or image path should be corrected before merge.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Include the banner asset or correct the image path before merging.

README.md references ./assets/knowledge-rag-banner.png, but the asset is not included in the repository. The banner therefore renders as a broken image. Add the asset at this path or reference an existing tracked file.
