What it does
Microbenchmarking is an agent skill from atherio-danp/cde-dotnetcc. Create, run, configure, and interpret BenchmarkDotNet microbenchmarks in the .NET API — measure and compare approaches, runtime configs, or package versions. Use when proving a performance change, comparing implementations, or validating a hot-path optimization. (Not for profiling or load testing.)
Its SKILL.md is about 980 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 Testing & QA, covering Load testing. It works with .NET. The repository describes itself as: Claude Code harness for .NET developers.
When your agent uses it
- Proving a performance change
- Comparing implementations
- Validating a hot-path optimization
Example prompts
- “/microbenchmarking”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep, Bash, mcp__serena__initial_instructions, mcp__serena__get_symbols_overview, mcp__serena__find_symbol, mcp__serena__find_referencing_symbols, mcp__serena__find_declaration, mcp__serena__find_implementations, mcp__serena__search_for_pattern, mcp__serena__get_diagnostics_for_file, mcp__serena__list_dir, mcp__serena__find_file, mcp__serena__create_text_file, mcp__serena__replace_symbol_body, mcp__serena__insert_after_symbol, mcp__serena__insert_before_symbol, mcp__serena__replace_content, mcp__serena__rename_symbol, mcp__serena__safe_delete_symbol
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Plan — pick the use case (coverage suite / investigation / change-validation / throwaway) and the
- Implement — [Benchmark] methods that return their result (so the JIT can't elide them); init in
- Validate — --job Dry to confirm it compiles/runs → one representative case at defaults → full suite.
What it can do on your machine
Read from SKILL.md and the folder at commit c72a3f9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrepBashmcp__serena__initial_instructionsmcp__serena__get_symbols_overviewmcp__serena__find_symbolmcp__serena__find_referencing_symbolsmcp__serena__find_declarationmcp__serena__find_implementations
…and 11 more on the same allowed-tools line.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
dotnet
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
Microbenchmarking loads about 979 tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 345 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Glob, Grep, Bash, mcp__serena__initial_instructions, mcp__serena__get_symbols_overview, mcp__s
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 345 words (~979 tokens).
“Use this to turn a perf claim (often from dotnet-performance-review) into measured evidence. C# (.cs) benchmark files are written via Serena.”

Questions about Microbenchmarking
What does Microbenchmarking do?
Create, run, configure, and interpret BenchmarkDotNet microbenchmarks in the .NET API — measure and compare approaches, runtime configs, or package versions. Microbenchmarking is an agent skill from atherio-danp/cde-dotnetcc.NET API — measure and compare approaches, runtime configs, or package versions.
When should I use Microbenchmarking?
Microbenchmarking fits situations like: proving a performance change; comparing implementations; validating a hot-path optimization.
How do I install Microbenchmarking in Claude Code?
Run `npx skills add atherio-danp/cde-dotnetcc --skill microbenchmarking -a claude-code`. Or copy the skill folder (.claude/skills/microbenchmarking in atherio-danp/cde-dotnetcc) into .claude/skills/microbenchmarking in your project. Claude Code loads it when a task matches its description.
How do I install Microbenchmarking in Codex?
Run `npx skills add atherio-danp/cde-dotnetcc --skill microbenchmarking -a codex`. Or copy the skill folder (.claude/skills/microbenchmarking in atherio-danp/cde-dotnetcc) into .agents/skills/microbenchmarking in your project. Codex loads it when a task matches its description.
Can I use Microbenchmarking in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add atherio-danp/cde-dotnetcc --skill microbenchmarking -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/microbenchmarking, .gemini/skills/microbenchmarking, .github/skills/microbenchmarking and .opencode/skills/microbenchmarking in your project.
What does Microbenchmarking need to run?
Going by SKILL.md and its folder, Microbenchmarking needs the command-line tools its instructions call (dotnet). Its frontmatter pre-approves these tools: Read, Glob, Grep, Bash, mcp__serena__initial_instructions, mcp__serena__get_symbols_overview, mcp__serena__find_symbol, mcp__serena__find_referencing_symbols, mcp__serena__find_declaration, mcp__serena__find_implementations, mcp__serena__search_for_pattern, mcp__serena__get_diagnostics_for_file, mcp__serena__list_dir, mcp__serena__find_file, mcp__serena__create_text_file, mcp__serena__replace_symbol_body, mcp__serena__insert_after_symbol, mcp__serena__insert_before_symbol, mcp__serena__replace_content, mcp__serena__rename_symbol, mcp__serena__safe_delete_symbol.
Does Microbenchmarking access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Microbenchmarking safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Microbenchmarking use?
No licence was found for Microbenchmarking or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Microbenchmarking use?
About 979 tokens (SKILL.md is roughly 3.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Microbenchmarking?
Skills that share tags, products or a category with Microbenchmarking: Microbenchmarking (dotnet/skills, 5.6k stars), Microbenchmarking (rodri-oliveira-dev/Dapper-FluentMap, 453 stars), Code Review (dotnet/macios, 2.9k stars) and Profiling (managedcode/dotnet-skills, 486 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
