📝 Walkthrough

Walkthrough

README.md was updated to add a "Usage examples" section containing curl commands and payload examples for the /api/graph_entities (GET), /api/chat (POST), /api/list_commits (POST), and /api/switch_commit (POST) endpoints. This is documentation-only; no code or routing changes.

Changes

Cohort / File(s)	Summary
Documentation `README.md`	Added a "Usage examples" section with concrete curl commands showing `Authorization: Bearer <YOUR_SECRET_TOKEN>` header and request payload examples for `/api/graph_entities` (GET), `/api/chat` (POST), `/api/list_commits` (POST), and `/api/switch_commit` (POST).

Poem

🐰
A little README, tidy and bright,
Four curl commands hopping into the light,
No code to alter, just examples to show,
Tokens and payloads in a neat little row,
Hooray for docs — onward we go! 🎉

🚥 Pre-merge checks | ✅ 5

✅ Passed checks (5 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title accurately and clearly describes the main change: adding API documentation for the specified endpoints (graph retrieval, query, and commit history).
Linked Issues check	✅ Passed	All three required APIs are documented: GET /graph_entities (retrieve graph), POST /chat (query), and POST /list_commits and POST /switch_commit (history changes).
Out of Scope Changes check	✅ Passed	Changes are limited to README documentation additions with no modifications to application logic, routing, or other unrelated files.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.

Inline comments:
In `@README.md`:
- Around line 228-230: The README example includes a literal auth token
("Authorization: OpenSesame") which can encourage reuse and trigger secret
scanners; update the example curl for the graph_entities endpoint to use a
placeholder or environment variable instead (e.g., replace the literal
Authorization header in the curl example for
"http://127.0.0.1:5000/graph_entities?repo=GraphRAG-SDK" with a safe token
reference like ${SECRET_TOKEN} or a named placeholder) so the README no longer
contains a real-looking secret.
- Around line 224-250: Update the curl examples to use the documented
environment variable name SECRET_TOKEN consistently (e.g., replace instances of
<.ENV_SECRET_TOKEN> with ${SECRET_TOKEN}) across the /graph_entities, /chat,
/list_commits, and /switch_commit examples in README.md so the snippets are
copy-pasteable and match the earlier .env example.

Rebased on staging and addressed review comments:

Env var consistency: Replaced all <.ENV_SECRET_TOKEN> with ${SECRET_TOKEN} to match the .env example and be copy-pasteable.
Literal auth token: Replaced Authorization: OpenSesame example with ${SECRET_TOKEN} placeholder to avoid triggering secret scanners.

Pull request overview

Adds an API Reference section to README.md to document graph retrieval, chat querying, and commit history endpoints.

Changes:

Added a new “API Reference” section with curl examples for graph retrieval, chat queries, and commit operations.
Added an additional keywords-like line near the end of the README.

💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

+```

The new API Reference duplicates the existing "## API Endpoints" section above and introduces conflicting/incorrect paths. Consider removing this section or merging it into the existing endpoints table to keep a single source of truth.

## API Reference

### Retrieve a graph

Fetch graph entities from a repository:

```bash

curl -X GET "http://127.0.0.1:5000/graph_entities?repo=<REPO_NAME>" -H "Authorization: ${SECRET_TOKEN}"

```

Example:

```bash

curl -X GET "http://127.0.0.1:5000/graph_entities?repo=GraphRAG-SDK" -H "Authorization: ${SECRET_TOKEN}"

```

### Send Query

Query your code graph using natural language:

```bash

curl -X POST http://127.0.0.1:5000/chat -H "Content-Type: application/json" -d '{"repo": "<REPO_NAME>", "msg": "<YOUR_QUESTION>"}' -H "Authorization: ${SECRET_TOKEN}"

```

### History change

List all commits:

```bash

curl -X POST http://127.0.0.1:5000/list_commits -H "Content-Type: application/json" -d '{"repo": "<REPO_NAME>"}' -H "Authorization: ${SECRET_TOKEN}"

```

Switch to a specific commit:

```bash

curl -X POST http://127.0.0.1:5000/switch_commit -H "Content-Type: application/json" -d '{"repo": "<REPO_NAME>", "commit": "<COMMIT_HASH>"}' -H "Authorization: ${SECRET_TOKEN}"

```

The documented URL is missing the /api prefix. The FastAPI route is /api/graph_entities, so these curl examples will 404 unless updated to use /api/graph_entities.

+```


Auth examples elsewhere in the README use Authorization: Bearer <YOUR_SECRET_TOKEN>. Here the header is shown as Authorization: ${SECRET_TOKEN}; since the backend accepts either raw token or Bearer, consider standardizing these examples to the Bearer form for consistency and clarity.

This line reads like a list of SEO keywords and isn’t referenced elsewhere in the README. If it’s not intentionally part of the documentation, consider removing it to avoid distracting from the actual content.

+```
+
+### History change


Section title "History change" is grammatically unclear. Consider renaming to something like "Commit history" or "History changes" to match the endpoints being documented.

Suggested change

### History change

### Commit history

…p README - Add /api prefix to all curl URLs (graph_entities, chat, list_commits, switch_commit) - Standardize auth header to Bearer format - Rename 'History change' section to 'Commit history' - Remove SEO keywords line Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

gkorland

Addressing remaining unresolved threads:

README.md:262 (missing /api prefix): Fixed in latest commit — all curl URLs now include the /api prefix.

README.md:282 (auth format): Fixed — standardized all examples to Authorization: Bearer <YOUR_SECRET_TOKEN> format.

README.md:283 (duplicate section): Fixed — removed the duplicate API Reference section, keeping only the existing API Endpoints table as single source of truth.

- Remove duplicate 'API Reference' section, merge curl examples into 'API Endpoints' as 'Usage examples' subsection - Standardize auth header to Bearer <YOUR_SECRET_TOKEN> placeholder - Move License section to end of file Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
