What it does
Udf Benchmark is an agent skill from Kilo-Org/kilo-marketplace. Assists with benchmarking and profiling the performance of an Apache Spark UDF on the GPU. This is step 3 of 3 in the UDF conversion workflow (udf-gen-test - udf-convert-to- - udf-benchmark). Use this skill when you have a CPU UDF and a RapidsUDF or SQL implementation, and need to benchmark the performance of the CPU UDF against the GPU implementation.
Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `CUDF_MICROBENCHMARKS.md`).
It sits in Data & Analytics, covering SQL. It works with SQL and Apache Spark. The repository describes itself as: Kilo Marketplace - A curated collection of Skills, MCP Servers, and Modes for enhancing AI agent capabilities across the Kilo ecosystem—including Kilo Code (VS Code extension)…
When your agent uses it
- You have a CPU UDF and a RapidsUDF
- SQL implementation
- Need to benchmark the performance of the CPU UDF against the GPU implementation
Example prompts
- “Use the udf-benchmark skill to assist with benchmarking and profiling the performance of an Apache Spark UDF on the GPU”
- “/udf-benchmark”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Implement BenchUtils
- Validate
- Generate Data and Run Benchmarks
- cuDF Microbenchmarks
What it can do on your machine
Read from SKILL.md and the folder at commit ff51758. 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 (its code samples are bash).
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
Udf Benchmark loads about 802 tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 272 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
Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 272 words (~802 tokens).
“Before making any edits, create a visible TODO checklist for every workflow step in this skill and keep it updated. Do not produce a final answer until every required checklist item is marked complete.”
