Example session with this skill installed
Review this pull request diff for bugs, memory leaks, and dead code. Clean up any issues and output the optimized code:
import { fetchUser, fetchPermissions, unusedHelper } from './api';
export async function processUsers(userIds: string[]) {
const unusedVar = "debug_mode";
for (let i = 0; i < userIds.length; i++) {
const user = await fetchUser(userIds[i]);
const perms = await fetchPermissions(user.id);
console.log(user, perms);
}
return true;
console.log("Processing complete");
}

📋 Audit Findings & Severity Report
| Severity | Location | Issue Type | Summary |
|---|---|---|---|
| 🔴 Critical | processUsers() loop | Performance / N+1 | Sequential await calls inside for loop cause high latency. |
| 🟡 Warning | Line 13 | Unreachable Code | console.log placed directly after an unconditional return. |
| 🟡 Warning | Line 1 & Line 4 | Dead Code | Unused import unusedHelper and unused variable unusedVar. |
🔍 Detailed Fixes
Async Bottleneck Resolution: Converted sequential for loop await calls into parallelized Promise.all() execution to reduce total execution time from O(N) network requests to O(1) sequential delays.
2. Dead Code Stripping: Removed unused variable unusedVar and unused import unusedHelper.
3. Unreachable Code Removal: Purged execution block following the explicit return true statement.
✨ Cleaned Master Output
import { fetchUser, fetchPermissions } from './api';
export async function processUsers(userIds: string[]): Promise<boolean> {
const userResults = await Promise.all(
userIds.map(async (id) => {
const user = await fetchUser(id);
const perms = await fetchPermissions(user.id);
return { user, perms };
})
);
userResults.forEach(({ user, perms }) => {
console.log(user, perms);
});
return true;

About this skill
Automated PR Review & Dead-Code Pruner is a deterministic code review engine built for Agensi. Unlike generic AI code reviews that focus on superficial style formatting, this skill focuses strictly on high-impact architectural issues, runtime risks, dead code elimination, and database performance bottlenecks.
Core Capabilities
- Dead Code & Unreachable Logic Removal: Automatically flags and strips unused symbols, orphaned imports, unreachable branches, and redundant variable assignments.
- Async & Resource Management Audit: Catches floating promises, unhandled rejections, dangling event listeners/timers, and sequential
awaitbottlenecks that should be parallelized withPromise.all(). - Database & Algorithmic Efficiency: Identifies N+1 query patterns inside loops and high cyclomatic complexity (nested loops >3 levels deep) to suggest clean guard clauses.
- Refactored Code Delivery: Generates structured severity matrices alongside zero-fluff, copy-paste ready refactored code blocks.
Compatible Workflows
Ideal for continuous integration checks, pull request audits, legacy codebase refactoring, and daily developer code hygiene routines.
