What it does
Write Tests is an agent skill from atherio-danp/cde-dotnetcc. Write and run tests for the .NET API following a plan's exact test list and our testing conventions — unit (domain/handlers) and integration (endpoint→DB), exact pass/fail/skip counts, never weakening a test. Use when adding or changing tests under apps/api/tests. Preloaded by the testing-expert agent.
Its SKILL.md is about 820 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 Test generation and API testing. It works with .NET. The repository describes itself as: Claude Code harness for .NET developers.
When your agent uses it
- Changing tests under apps/api/tests
- Tasks that involve Test generation
- Tasks that involve API testing
Example prompts
- “/write-tests”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep, Edit, Write, Bash, Skill, 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
5 steps, taken from the first numbered list in SKILL.md.
- Implement the plan's "Exact test list" verbatim — each named test asserts exactly what the plan says it
- Write the .cs test files via Serena.
- Run the suite and report EXACT counts — e.g. passed 42 / failed 0 / skipped 1, never "tests pass".
- Never weaken, skip, disable, or delete a test (or disable an analyzer) to get green. A failing test that
- Note any "Known coverage gap" the harness cannot verify.
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:
ReadGlobGrepEditWriteBashSkillmcp__serena__initial_instructionsmcp__serena__get_symbols_overviewmcp__serena__find_symbol
…and 14 more on the same allowed-tools line.
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
Write Tests loads about 818 tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 301 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, Edit, Write, Bash, Skill, mcp__serena__initial_instructions, mcp__serena__get_symb
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 301 words (~818 tokens).

Write Tests is an agent skill from atherio-danp/cde-dotnetcc.NET API following a plan's exact test list and our testing conventions — unit (domain/handlers) and integration (endpoint→DB), exact pass/fail/skip counts, never weakening a test.
When should I use Write Tests?
Write Tests fits situations like: changing tests under apps/api/tests; tasks that involve Test generation; tasks that involve API testing.
How do I install Write Tests in Claude Code?
Run `npx skills add atherio-danp/cde-dotnetcc --skill write-tests -a claude-code`. Or copy the skill folder (.claude/skills/write-tests in atherio-danp/cde-dotnetcc) into .claude/skills/write-tests in your project. Claude Code loads it when a task matches its description.
How do I install Write Tests in Codex?
Run `npx skills add atherio-danp/cde-dotnetcc --skill write-tests -a codex`. Or copy the skill folder (.claude/skills/write-tests in atherio-danp/cde-dotnetcc) into .agents/skills/write-tests in your project. Codex loads it when a task matches its description.
Can I use Write Tests 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 write-tests -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/write-tests, .gemini/skills/write-tests, .github/skills/write-tests and .opencode/skills/write-tests in your project.
What does Write Tests need to run?
SKILL.md names no scripts, command-line tools or credentials: Write Tests is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Glob, Grep, Edit, Write, Bash, Skill, 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 Write Tests 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 Write Tests 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 Write Tests use?
No licence was found for Write Tests or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Write Tests use?
About 818 tokens (SKILL.md is roughly 3.3k 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 Write Tests?
Skills that share tags, products or a category with Write Tests: Find Untested Sources (dotnet/skills, 5.6k stars), ScottPlot Test Runner (ScottPlot/ScottPlot, 6.8k stars), BiSheng E2E Test Generator (dataelement/bisheng, 12k stars) and Raven Test Triage (marinasundstrom/raven, 108 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
