# Review PR Skill

Review one open pull request at a time for the awesome-quant curated list. Always start with the oldest unreviewed open PR.

**IMPORTANT: Always use GitHub MCP tools for all GitHub operations.** Do not fall back to bash commands like `gh` or other tools — use the GitHub MCP interface exclusively.

## Workflow

### Step 1: Find the oldest open PR

Use the `mcp__github__list_pull_requests` tool to list open pull requests sorted by creation date (ascending). Pick the oldest one. Show the user which PR you're reviewing (number, title, author, creation date).

### Step 2: Check for merge conflicts

Use the `mcp__github__pull_request_read` tool with method `get` to read the PR details. If the PR has merge conflicts, report this to the user and stop — the contributor needs to resolve conflicts before review can proceed. Use the `mcp__github__add_issue_comment` tool to leave a polite comment asking them to rebase.

### Step 3: Fetch the diff and extract added lines

Use the `mcp__github__pull_request_read` tool with method `get_diff` to read the PR diff. Focus only on changes to `README.md`. If the PR modifies files other than `README.md` (like `parse.py`, `site/`, etc.), flag this as unusual — most contributions should only touch `README.md`.

### Step 4: Automatic rejection checks

Reject the PR immediately (close with a polite comment) if any of these apply:

- **Multiple unrelated projects** — multiple projects should only be submitted together if they are closely related (same market/exchange, same author, same service, or address a specific domain gap). Check the PR description for clear rationale. If unrelated, ask the contributor to split into separate PRs.
- **Empty PR description** — the contributor must explain what they're adding and why (especially if multiple projects).
- **Duplicate entries** — the same project name or URL appears multiple times within the PR or already in `README.md`.
- **Archived or abandoned** — the project has no activity in 12+ months.

### Step 5: Validate each added entry

For every new line added to `README.md`, check the following:

#### 5a. Entry format

Each entry MUST include one or more language tags and match one of these accepted formats:

**Single language:**
```
- [Project Name](https://github.com/owner/repo) - `Python` - Short description ending with a period.
```

**Multiple languages:**
```
- [Project Name](https://github.com/owner/repo) - `Python` `Rust` - Short description ending with a period.
```

**Project with website and GitHub repo:**
```
- [Project Name](https://project-site.com) - `Python` - Short description ending with a period. [GitHub](https://github.com/owner/repo)
```

**CRAN project (with optional GitHub link):**
```
- [Package Name](https://cran.r-project.org/package=pkgname) - `R` - Short description ending with a period.
- [Package Name](https://cran.r-project.org/package=pkgname) - `R` - Short description ending with a period. [GitHub](https://github.com/owner/repo)
```

**PyPI project (with optional GitHub link):**
```
- [package-name](https://pypi.org/project/package-name/) - `Python` - Short description ending with a period.
- [package-name](https://pypi.org/project/package-name/) - `Python` - Short description ending with a period. [GitHub](https://github.com/owner/repo)
```

The core regex used by `parse.py` to extract entries is: `^\s*- \[(.*)\]\((.*)\) - (.*)$`

Specifically check:
- Starts with `- ` (dash + space)
- Followed by a markdown link `[Name](URL)`
- Followed by ` - ` (space, dash, space)
- **MUST include one or more language tags in backticks** (e.g., `` `Python` ``, `` `Python` `Rust` ``) followed by ` - `
- Followed by a description that ends with a period `.`
- The period must come before the optional `[GitHub](url)` link
- The `[GitHub]` link, if present, must use the exact format `[GitHub](https://github.com/owner/repo)`

If the entry doesn't match, report exactly what's wrong (missing language tags, missing period, wrong separator, etc.).

#### 5b. URL validation

- **GitHub URLs are preferred.** If the primary URL points to `github.com`, that's ideal.
- **CRAN URLs** (`cran.r-project.org`) are acceptable for R packages.
- **PyPI URLs** (`pypi.org`) are acceptable for Python packages.
- **Non-GitHub URLs with `[GitHub]` link**: If the primary URL is a project website but includes a `[GitHub](url)` link in the description, that's the preferred format for non-GitHub projects.
- **Non-GitHub URLs without `[GitHub]` link**: Flag with a suggestion to add a `[GitHub](url)` link if one exists, since GitHub repos enable automated tracking of stars and activity.
- All URLs must use `https://`.

#### 5c. Section placement

The README is now organized by **category** (not by language). Look at which `##` (category) heading the entry was added under. Evaluate whether the project fits that section:

- Does the project's purpose match the category? (e.g., a backtesting framework should be under `## Trading & Backtesting`, not under `## Technical Indicators`)
- Commercial/proprietary projects must go under `## Commercial & Proprietary Services`.
- If the placement seems wrong, suggest a better section.

The current category sections in the README are:

1. Numerical Libraries & Data Structures
2. Financial Instruments & Pricing
3. Technical Indicators
4. Trading & Backtesting
5. Portfolio Optimization & Risk Analysis
6. Factor Analysis
7. Sentiment Analysis & Alternative Data
8. Time Series Analysis
9. Market Data & Data Sources
10. Prediction Markets
11. Calendars & Market Hours
12. Visualization
13. Excel & Spreadsheet Integration
14. Quant Research Environments
15. Cross-Language Frameworks
16. Reproducing Works, Training & Books
17. Commercial & Proprietary Services
18. Related Lists

If the project doesn't fit any existing section, suggest the closest match or recommend creating a new category section (rare).

#### 5d. Duplicate check

Use the `mcp__github__get_file_contents` tool to fetch the current `README.md` from the repository, then search through it to ensure the project name and URL are not already listed.

#### 5e. Quality check

- **Active**: Project should show recent activity (commits within the last 12 months).
- **Documented**: Project should have a clear README with usage examples.

### Step 6: Summarize findings

Present a clear summary:

```
PR #<number>: <title>
Author: <author>
Created: <date>

Entries reviewed: <count>

<For each entry>
  - [Name](URL) - Description
    Format: OK / ISSUE: <details>
    URL: GitHub / CRAN / PyPI / WARNING: <details>
    Section: OK (<section>) / SUGGESTION: Move to <section>
    Duplicate: No / YES: Already listed at line <N>
    Quality: OK / WARNING: <details>
</For each entry>

Conflicts: None / YES: Needs rebase

Verdict: APPROVE / NEEDS CHANGES / REJECT
```

### Step 7: Take action

Use GitHub MCP tools exclusively for all PR interactions:

- **If everything passes**: Ask the user for confirmation, then use the `mcp__github__merge_pull_request` tool to merge the PR.
- **If there are fixable issues**: Use the `mcp__github__add_issue_comment` tool to leave a constructive review comment on the PR listing what needs to be fixed. Be polite and specific — these are open-source contributors. Link to `CONTRIBUTING.md` for reference.
- **If it should be rejected** (automatic rejection criteria): Use the `mcp__github__update_pull_request` tool to close the PR with a polite explanation and link to `CONTRIBUTING.md`. Then leave a comment using `mcp__github__add_issue_comment` explaining the closure reason.

When leaving comments, be friendly and grateful for the contribution. Example tone:
> Thanks for the contribution! A couple of things to address before we can merge:
> - The description should end with a period.
> - Consider adding a `[GitHub](url)` link so we can track activity.
>
> Please see our [contributing guidelines](https://github.com/wilsonfreitas/awesome-quant/blob/main/CONTRIBUTING.md) for the accepted entry formats.

**For multiple-project PRs:** If entries have mixed results (some pass, some need fixes), list all issues together and ask the contributor to fix all at once rather than cherry-picking individual entries. If the relationship between projects isn't clear from the description, ask for clarification of why they should be grouped.
