Code Review via Email
Need a second pair of eyes on your code? Email it to a SlyReply code review agent and get detailed feedback in minutes — no pull request required.
Code Review Agents
| Agent | Focus |
|---|---|
| DJ Debug | Bug detection, logic errors, edge cases |
| Code Reviewer Rex | Code quality, patterns, best practices |
| Security Sam | Vulnerability scanning, security anti-patterns |
| Refactor Rita | Code structure, DRY improvements, readability |
Sending Code for Review
You can include code directly in your email body using plain text:
To: dj-debug@slyreply.ai
Subject: Review this Python function
Hi DJ, can you review this function? It is supposed to
merge two sorted lists but I am getting wrong results
for some inputs:
def merge_sorted(a, b):
result = []
i = j = 0
while i < len(a) and j < len(b):
if a[i] <= b[j]:
result.append(a[i])
i += 1
else:
result.append(b[j])
return result
What You Get Back
The agent replies with a structured review that typically includes:
- Bug identification — specific lines with issues and explanations
- Fix suggestions — corrected code with inline comments
- Edge case warnings — inputs that could break the function
- Performance notes — time/space complexity observations
- Style recommendations — naming, formatting, and idiomatic improvements
Sharing Larger Snippets
Source-code and plain-text files (.py, .js, .ts, .go, .json, .yaml, .sql, .txt, and similar) are not read as attachments — only PDFs and images are ingested natively (see Processing Email Attachments). If you attach a .py or .txt file, the reply will include an "Attachment not read" notice naming it.
For larger codebases, share the code one of these ways instead:
- Paste it into the email body inside a fenced code block — this is the most reliable option and keeps the language hint intact
- Convert the file to PDF before attaching if you'd rather send a file (Pro and Power read PDFs natively)
- Send a screenshot of the code as an image attachment (Pro and Power read images natively) — best for short snippets
Best Practices
- Describe the intent — tell the agent what the code is supposed to do
- Mention the language and framework — helps the agent give idiomatic suggestions
- Ask specific questions — "Is this thread-safe?" gets a better answer than "Review this"
- Iterate in the thread — paste your revised code in a reply to get follow-up feedback
