Walkthrough

Documentation additions for the Sentiment Analysis Tool project. Four new markdown files provide an overview (README), architecture details, setup instructions, and usage guidelines for the frontend (Next.js) and model API (FastAPI) components.

Changes

Cohort / File(s) Summary
Documentation & Setup Guides
README.md, docs/architecture.md, docs/setup.md, docs/usage.md
Added comprehensive documentation package: main README with project overview and quick start instructions, architecture documentation detailing frontend (Next.js) and backend (FastAPI) structure with runtime flow, setup guide with installation and development commands for local and Docker environments, and usage guide with API examples and integration notes.

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~5 minutes

  • Verify architecture documentation accurately reflects actual project structure
  • Confirm setup commands are complete and tested for both local and Docker workflows
  • Ensure API endpoint descriptions and examples match actual implementation
  • Check that file paths and prerequisites are accurate

Poem

🐰 With whiskers twitching and notes in paw,
I've documented all without a flaw,
From setup to usage, the guide now shines,
Architecture mapped in clear, crisp lines!
Happy coding, friends—no more mysteries!

1-22: LGTM! The usage documentation is clear, well-structured, and provides both UI and direct API examples with helpful notes on API expectations.

- `frontend/` — Next.js app and UI components in `frontend/components` and `frontend/app`.
- `model-lab/app/main.py` — FastAPI app; accepts multipart image uploads and returns predicted emotion and probabilities.
- `model-lab/app/model.py` — Model wrapper that loads the ONNX model and exposes a `predict()` method.
- `model-lab/models/onxx_models/emotion-ferplus-8.onnx` — The ONNX emotion recognition model file.

⚠️ Potential issue | 🟡 Minor

Fix typo in ONNX model path.

Line 15 contains "onxx_models" which should be "onnx_models" (ONNX format).

🔎 Proposed fix
-- `model-lab/models/onxx_models/emotion-ferplus-8.onnx` — The ONNX emotion recognition model file.
+- `model-lab/models/onnx_models/emotion-ferplus-8.onnx` — The ONNX emotion recognition model file.
📝 Committable suggestion

‼️ 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.

Suggested change
- `model-lab/models/onxx_models/emotion-ferplus-8.onnx` — The ONNX emotion recognition model file.
- `model-lab/models/onnx_models/emotion-ferplus-8.onnx` — The ONNX emotion recognition model file.
🤖 Prompt for AI Agents
In docs/architecture.md around line 15, the ONNX model directory name is
misspelled as "onxx_models"; update the path to "onnx_models" so the line reads
`model-lab/models/onnx_models/emotion-ferplus-8.onnx`, ensuring the directory
name correctly matches the ONNX format and project structure.


Notes
- The FastAPI app configures CORS; by default the frontend origin is `http://localhost:3000`.
- The ONNX model used is at `model-lab/models/onxx_models/emotion-ferplus-8.onnx`.

In docs/setup.md around line 48, the ONNX model path contains a typo
("onxx_models"); update the path segment to "onnx_models" so the line reads the
model location as model-lab/models/onnx_models/emotion-ferplus-8.onnx; ensure
any other references in this file use the corrected "onnx_models" spelling.


Key pieces
- Frontend: `frontend/` — Next.js app (TypeScript) serving the UI and demo at `/demo`.
- Model API: `model-lab/` — FastAPI app that loads `models/onxx_models/emotion-ferplus-8.onnx` and exposes a `/predict` endpoint.

⚠️ Potential issue | 🟡 Minor

Wrap bare URL in markdown link.

Line 41 uses a bare URL which violates markdown linting standards (MD034). Wrap it in a proper markdown link format.

🔎 Proposed fix
-- Demo UI: http://localhost:3000/demo
+- Demo UI: [http://localhost:3000/demo](http://localhost:3000/demo)

41-41: Bare URL used

(MD034, no-bare-urls)

🤖 Prompt for AI Agents
In README.md around line 41, the bare URL "http://localhost:3000/demo" violates
markdown linting (MD034); replace the bare URL with a markdown link by wrapping
the URL in square brackets for link text and parentheses for the target (e.g.,
[Demo UI](http://localhost:3000/demo)) so the link is properly formatted and
linter-compliant.
