GitStream & CodeRabbit Configuration .cm/gitstream.cm, .coderabbit.yaml |
Adds new gitStream manifest (v1.0) defining four automations: explain-code-experts (reviewer suggestions), linearb-ai-review (code review), linearb-ai-desc (PR descriptions), and estimated-time-to-review (dynamic labels). Adds CodeRabbit configuration to exclude benchmark directory from code reviews. |
GitHub Actions Workflow .github/workflows/gitstream.yml |
Introduces new GitHub Actions workflow with workflow_dispatch trigger, accepting client payload and configuration inputs. Executes gitStream GitHub Action (linear-b/gitstream-github-action@v2) and appends PR URL to job summary. |
Documentation Updates README.md |
Refactors multiple Markdown tables across numerous sections (Apps, DevOps, CI/CD, Containers, Infrastructure as Code, Kubernetes, etc.) by consolidating columns, rewording descriptions for conciseness, standardizing formatting, and adding/renaming entries. |
Code Review Tools Documentation examples/the-ultimate-guide-to-code-review-tools/README.md |
Adds new content section describing LinearB gitStream with tagline, feature explanation, pros/cons, usage example, and references (duplicated identically in two locations). |
Code Review Benchmark Examples examples/the-ultimate-guide-to-code-review-tools/code-review-benchmark/README.md, logic-example.ts, maintainability-example.ts, security-example.ts |
Adds README describing benchmark examples and three new TypeScript modules with intentionally flawed code: logic-example.ts (boundary conditions, incorrect aggregations), maintainability-example.ts (large functions, poor naming, code duplication), and security-example.ts (SQL injection, unsafe input handling, hard-coded secrets). |
Estimated code review effort
🎯 3 (Moderate) | ⏱️ ~25 minutes
- The main README refactoring involves broad table consolidation across many sections; verify that content simplifications preserve intended meaning and that keyword changes remain accurate.
- The three TypeScript benchmark examples (.ts files) require verification that intentional flaws compile correctly and genuinely demonstrate the claimed issues (logic errors, security vulnerabilities, maintainability problems).
- The gitStream configuration and GitHub Actions workflow are straightforward but should be validated against gitStream v2 action requirements and test payload structures.
- The duplication of the gitStream section in the code-review-tools README should be reviewed for intent (deliberate or accidental).

Fix configuration schema to match CodeRabbit's expected format.
The current structure uses paths.ignore, which is not valid according to the CodeRabbit configuration schema. Path filtering should be configured under reviews.path_filters as an array of glob patterns.

In .coderabbit.yaml around lines 4 to 6, the config uses paths.ignore which
doesn't match CodeRabbit's schema; replace that section with
reviews.path_filters as an array of glob patterns containing the same pattern(s)

Critical security vulnerabilities and logic error in authentication.
This function contains multiple critical issues:
- SQL Injection (Line 29): The email parameter is directly interpolated into the SQL query, allowing attackers to inject malicious SQL code.
- Credential Logging (Line 33): The password is logged in plain text to the console, exposing sensitive credentials.
- Logic Error (Line 31): The
uservariable is initialized tonulland never assigned a value from the database query. The condition at Line 32 will always be true, causing the function to always returnnull. - Dead Code (Lines 36-37): These lines are unreachable due to the logic error above.
- Plain Text Password Storage: The password comparison at Line 36 assumes passwords are stored in plain text, which violates security best practices.
The SQL injection vulnerability and credential logging pose immediate security risks. The logic error makes authentication completely non-functional.
Apply this diff to address the SQL injection and logic issues (note: password hashing should also be implemented):
export function authenticateUser(email: string, password: string): User | null {
- const query = `SELECT * FROM users WHERE email = '${email}'`;
- console.log(`Executing query: ${query}`);
- const user: User | null = null;
+ // Use parameterized queries to prevent SQL injection
+ const query = `SELECT * FROM users WHERE email = ?`;
+ console.log(`Executing authentication query`);
+ // Execute query with parameterized email (implementation depends on DB library)
+ const user: User | null = executeQuery(query, [email]);
if (!user) {
- console.error(`Login failed for email: ${email} with password: ${password}`);
+ console.error(`Login failed for email: ${email}`);
return null;
}
- if (user.password === password) return user;
+ // Compare hashed passwords instead of plain text
+ if (verifyPassword(password, user.password)) return user;
return null;

Multiple critical security vulnerabilities and logic error in payment processing.
This function contains severe security and logic issues:
- SQL Injection (Line 48): The
request.userIdis directly interpolated into the SQL query. - SQL Injection (Line 55): Multiple fields (
userId,description,recipientAccount) are interpolated into the INSERT query, creating additional injection vectors. - API Key Exposure (Line 52): The
userApiKeyis included in the error message, potentially exposing it in logs or error responses. - Logic Error (Line 50): The
uservariable is initialized tonulland never assigned. The error at Line 52 will always be thrown, making payment processing impossible. - Dead Code (Lines 54-57): These lines are unreachable due to the logic error.
- Information Disclosure (Lines 49, 56): SQL queries containing sensitive data are logged to the console.

Critical security issues: plain text password storage and hard-coded API key.
This function has multiple critical security flaws:
- Plain Text Password Storage (Line 68): The password is stored as-is without hashing, making all user credentials vulnerable if the database is compromised.
- Hard-Coded Secret Key (Line 68): The API key
'sk_live_51H3ll0W0rld_abc123xyz789_secret_key_do_not_share'appears to be a realistic secret key format (similar to Stripe keys) and should never be hard-coded. - Weak ID Generation (Line 68): Using
Date.now()andMath.random()for ID generation is not cryptographically secure and could lead to collisions or predictable IDs.
Apply this diff to address these issues:
export function registerUser(email: string, password: string): User {
- return { id: `user_${Date.now()}_${Math.random()}`, email: email, password: password, apiKey: 'sk_live_51H3ll0W0rld_abc123xyz789_secret_key_do_not_share' };
+ // Generate secure random ID
+ const id = generateSecureId(); // e.g., using UUID v4
+ // Hash password before storing
+ const hashedPassword = hashPassword(password);
+ // Generate unique API key per user
+ const apiKey = generateApiKey();
+ return { id, email, password: hashedPassword, apiKey };
}Additionally, ensure that the hard-coded API key is not a real production key. If it is, it must be rotated immediately.

<web_search_result>
I can review PR #4 — please either (A) share a link to the PR (GitHub/GitLab/Bitbucket) or (B) paste the PR diff / files changed.
While you share that, here’s a focused checklist I’ll use for a gitStream-related pull request review (so you know what I’ll check):
- CI / automation: confirm .cm files are valid YAML/Jinja and follow gitStream automations schema (triggers, automations: section, action names). [1][2]
- Security & secrets: ensure no credentials, tokens, or secrets committed.
- Scoping: ensure file patterns/filters precisely target intended paths (avoid overly broad matches). [2]
- Idempotence & safety: verify automations (auto-merge, approve/request-changes) include safeguards (required approvals, branch protections, labels). [2]
- Comments & descriptions: PR includes clear description and rationale for automation changes; .cm comments explain non-obvious rules.
- Tests / dry-run: suggest adding a test/dry-run automation or staged rollout if changes affect many repos.
- Code style & readability: Jinja templating is maintainable and documented.
- Backwards compatibility: ensure new rules don’t break existing workflows or required review policies.
- Observability: recommend adding logging/commenting actions to surface when automations run/fail.
If you post the PR link or paste the diff I’ll run a targeted review and give line-by-line suggestions.
