find-leaks

find-leaks is a command for Claude Code from rohitg00/awesome-claude-code-toolkit. It costs 0 tokens per session (324 once invoked), scanned A, original, Apache-2.0.

A command for finding memory leaks, where an application keeps objects in memory after they are no longer needed. It repeats a workload, measures memory growth, and traces what is retaining the objects.

In plain words
What is it for?
Use it to check event listeners, closures, caches, timers, and other common leak sources, then verify that fixes work. It reports affected files, estimated memory impact, and suggested fixes.
Why use it?
It helps distinguish a real leak from normal memory allocation and points to the code responsible. This reduces the need to inspect memory problems manually.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

find-leaks scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/find-leaks - Find Memory Leaks

Detect and diagnose memory leaks in the application.

Steps

  1. Configure the application for leak detection with appropriate tooling
  2. Establish a baseline memory measurement at application startup
  3. Run a repetitive workload: process N requests, render N times, or execute N iterations
  4. Measure memory after each iteration to detect steady growth
  5. Force garbage collection between measurements to isolate true leaks
  6. Identify objects that grow in count across iterations without being released
  7. Trace the retention path: what is holding references to leaked objects
  8. Check common leak sources:
    • Event listeners not removed on cleanup
    • Closures capturing large scopes
    • Growing caches without eviction
    • Circular references preventing GC
    • Timers and intervals not cleared
  9. For each leak, identify the source file, line, and the allocation site
  10. Suggest specific fixes: removeEventListener, WeakRef, cache size limits
  11. Verify the fix by re-running the leak detection scenario
  12. Report: leaks found, estimated memory impact, fix suggestions

Rules

  • Run leak detection for at least 100 iterations to confirm a pattern
  • Distinguish between expected memory growth and actual leaks
  • Check both heap memory and native memory (buffers, file handles)
  • Verify leaks are reproducible before reporting
  • Consider the application lifecycle; some growth is expected during warmup
  • Check for connection pool leaks (database, HTTP, WebSocket)
  • Report the growth rate (bytes per iteration) for each detected leak

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

find-leaks is a command published in the GitHub repository rohitg00/awesome-claude-code-toolkit (2,598 stars, last pushed 3mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 324 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
