KumoApp: Skill for Codex

.agents/skills/ios-memgraph-leaks/SKILL.md

ios-memgraph-leaks is a skill for Codex from ProjectKumo/KumoApp. It costs 73 tokens per session (936 once invoked), scanned A, original, AGPL-3.0.

A guide for finding and explaining memory leaks in iOS applications using Apple's leaks and memgraph tools, which show objects that remain in memory unexpectedly.

In plain words
What is it for?
Use it to capture and compare memory graphs, investigate leaks after navigation or logout, and verify that a leak fix worked.
Why use it?
It provides evidence for suspected retain cycles or memory growth instead of relying only on code inspection or guesswork.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is ProjectKumo/KumoApp's own configuration. It tells Codex how to work on KumoApp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything KumoApp configures →

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

ios-memgraph-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 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/capture_sim_memgraph.sh, scripts/summarize_memgraph_leaks.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Changes

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.
