Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 30 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00141 | $0.03474 |
| Opus 5.5 | $0.00056 | $0.01390 |
| Sonnet 5.5 | $0.00028 | $0.00695 |
| Haiku 4.5 | $0.00014 | $0.00347 |
Grade A, and why
migrate-xunit-to-mstest scanned grade A with 0 findings 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 1mo ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
xUnit -> MSTest Migration
Convert xUnit.net v2 or v3 tests to MSTest v4 without changing the target framework or test platform. A successful migration builds, discovers the same tests, and preserves pass/fail results and execution semantics.
Scope
Use this skill only when the project contains xUnit packages or source and the user wants MSTest. If the project already uses MSTest and contains no xUnit tests, report that no framework migration is needed and make no changes.
Do not combine this framework conversion with a target-framework upgrade or VSTest/MTP migration. Complete and verify one migration before starting another.
Workspace Contract
- Continue after skill activation. Search the current working directory for the staged project and source; never look for user files under this skill's base directory.
- Open the literal paths returned by glob/search. If one reader or patch tool rejects a path that was just found, retry with another available tool. Do not ask the user for a path until current-workspace discovery is exhausted.
- Classify by the requested deliverable: "convert this project" means edit, build, and test; "give me a plan" or "how would I convert it?" means answer. Do not replace execution with "please provide the files" when files are present.
- The final response must state the source xUnit version, preserved runner, changed files, each high-risk semantic mapping applied, and actual test counts. Assertions about fixture lifetime, Owner mapping, cancellation, or parallelization must be visible in the resulting source, not only prose.
Response Mode
- Full migration request: inspect the project, make the edits, build, and run tests. Do not stop after giving a plan.
- Focused compile error or API question: inspect the relevant code and apply only that mapping. Do not narrate the entire workflow.
- Unsupported target framework: stop before changing packages. MSTest v4 requires .NET 8+ or .NET Framework 4.6.2+ for test applications; offer a separately approved TFM upgrade or MSTest v3 as the intermediate target.
What ships with it
2 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.
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.

migrate-xunit-to-mstest is a skill published in the GitHub repository managedcode/dotnet-skills (490 stars, last pushed 3d ago), licensed MIT. It adds 141 tokens to every session and 3,474 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
