ios-ettrace-performance

ios-ettrace-performance is a skill for Codex from Bronc-X/Lotus. It costs 32 tokens per session (2,189 once invoked), scanned C, original, no licence file.

A tool for recording and reading ETTrace performance profiles from the iOS Simulator. An ETTrace profile is a recording that shows how an app uses time and the processor.

In plain words
What is it for?
Use it to profile app launch or runtime latency, compare recordings, and find processor-heavy call stacks.
Why use it?
It helps reveal slow startup, runtime delays, and code that uses too much processor time.

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 C, and why

ios-ettrace-performance scanned grade C with 1 finding 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 7d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/analyze_flamegraph_json.py, scripts/collect_ios_dsyms.sh), 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
