What it does
System Profile is an agent skill from AI4Scientist/nano-scientist. Profile a target (script, process, GPU, memory, interconnect) using external tools and code instrumentation. Produces structured performance reports with actionable recommendations. Use when user says "profile", "benchmark", "bottleneck", or wants performance analysis.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in AI & LLM Engineering, covering Performance optimization. It works with NVIDIA AI Platform. The repository describes itself as: An autonomous research agent that turns a topic into a peer-reviewed technical report.
When your agent uses it
- User says profile
- Wants performance analysis
Example prompts
- “profile”
- “benchmark”
- “bottleneck”
- “/system-profile”
Requirements
- Python 3
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Determine the profiling target
- Choose profiling methods
- Key dimensions to investigate
- Instrumentation guidelines
- Run profiling
- Produce the report
What it can do on your machine
Read from SKILL.md and the folder at commit 7132192. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
System Profile loads about 1.1k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 530 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 530 words (~1,136 tokens).
“Profile the specified target and summarize the results. Target: $ARGUMENTS”
- name
- system-profile
- argument-hint
- <target, e.g. "train.py", "gpu", "pid 1234", "vllm serving">
