What it does

Health Check is an agent skill from codewithmukesh/dotnet-claude-kit. Multi-dimensional health assessment for .NET projects with letter grades (A-F) using Roslyn MCP tools. Evaluates 8 dimensions: build health, code quality, architecture, test coverage, dead code, API surface, security posture, and documentation. Produces a structured report card with actionable recommendations. Load this skill when: "health check", "how healthy is this", "project health", "code quality report", "grade this project", "assess codebase", "quality audit", "technical assessment", "codebase review"…

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/grading-rubric.md`).

It sits in Development, covering Code quality, Test coverage and MCP servers. It works with .NET. The repository describes itself as: Make Claude Code a .NET 10 Expert. The licence is MIT.

When your agent uses it

  • Tasks that involve Code quality
  • Tasks that involve Test coverage
  • Tasks that involve MCP servers

Example prompts

  • “health check”
  • “how healthy is this”
  • “project health”
  • “/health-check”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Choose Scope
  2. Run the Dimensions
  3. 5: Triage Gate (before any grade is assigned)
  4. Grade and Aggregate
  5. Report

What it can do on your machine

Read from SKILL.md and the folder at commit 2330089. 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

    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

Health Check loads about 1.6k tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 136 tokens; SKILL.md has 645 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~136
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.1k

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.

/health-check — 8-Dimension Project Assessment

What

Runs a data-driven health assessment across 8 dimensions, each graded A-F with the specific data points that produced the grade, and rolls them into a GPA. Gut feeling is not a grade: every dimension uses MCP tools or CLI commands, and every grade below A comes with specific, prioritized, effort-estimated fixes — "add test classes for OrderService, PaymentProcessor, ShippingCalculator" is actionable; "improve test coverage" is not.

This skill owns the canonical grading system for the kit. The full rubrics, GPA scale, and report template live in references/grading-rubric.md — load that file when running an assessment.

Tone is diagnostic, not punitive: a C grade is an improvement path, not a failure.

When

  • Onboarding to an unfamiliar or new project — set the baseline
  • "How healthy is this?", "grade this project", "codebase review", "report card"
  • Pre-release quality gate, or monthly/quarterly maintenance review
  • After a cleanup sprint (/de-sloppify) — re-grade to show progress
  • Tech-debt prioritization — lowest grades get the next sprint's attention

How

Step 1: Choose Scope
ScenarioDimensions
Full assessment (onboarding, pre-release, monthly review)All 8
Quick health (mid-sprint checkpoint, before a demo, after a merge)1-4 only
After major refactor1 (Build), 3 (Architecture), 4 (Tests)
Post-dependency update1 (Build), 7 (Security)
After cleanup sprintRe-grade only the cleaned dimensions
Step 2: Run the Dimensions

Read references/grading-rubric.md for the grade thresholds, then collect data per dimension. For deep code-quality dimensions, delegate to the code-reviewer agent with the code-review skill.

#DimensionData source
1Build Healthdotnet build --no-restore — errors + warnings
2Code QualityMCP detect_antipatterns — read summary, grade high-confidence only
3ArchitectureMCP get_project_graph + detect_circular_dependencies (projects AND types)
4Test CoverageMCP get_test_coverage_map — check applicable first (structural, not line coverage)
5Dead CodeMCP find_dead_code(scope: "solution") — grade high-confidence; ignore conventionFiltered
6API SurfaceMCP get_public_api + find_references — overexposure, return-type consistency
7Security Posturedotnet list package --vulnerable --include-transitive + secrets/auth spot check (deep dive: /security-scan)
8DocumentationXML doc coverage on public APIs + README currency

Step 2.5: Triage Gate (before any grade is assigned)

Detector output is evidence, not a grade. Pass every finding through this gate first — it is what stops a noisy count becoming a wrong letter.

  1. Read summary, not the violation list. summary.byId is complete even when the list is truncated. Never sample a truncated list and extrapolate.
  2. Drop suppressed. Record the count and summary.suppressionConfig in the report so suppression stays visible.
  3. Set aside medium. These are review items, not grade inputs. Summarise them by category; do not fix or count them.
  4. Grade high only. These are wrong regardless of context.
  5. Check invariants. If a signal contradicts something the target repo's CLAUDE.md documents as deliberate, the invariant wins — verify before grading.
  6. Read before asserting. Never describe a finding you have not opened. If you cannot open all of them, report the ones you did and say so.

Fill in the triage table from references/grading-rubric.md as you go. If the table cannot be filled, the dimension is not ready to grade.

Step 3: Grade and Aggregate

Apply the rubric thresholds exactly — never grade on a curve ("pretty good for a project this size" is how standards erode; 15 warnings is a C regardless of project size). Convert to GPA (A=4.0 … F=0.0), averaging only the dimensions actually graded — a dimension marked "Not assessed" is excluded from the GPA, never scored as an F.

Step 4: Report

Produce the report card from the template in references/grading-rubric.md: grades table with key findings, overall GPA, and priority recommendations — each with named types/files, priority order, and effort estimates. If a previous report exists, append the trend comparison table.

Example

User: /health-check

Claude: Running full 8-dimension assessment...

| Dimension | Grade | Key Finding |
|-----------|-------|-------------|
| Build Health | A | 0 errors, 2 warnings |
| Code Quality | B | 3 high-confidence findings in 4.2K lines; 31 medium untriaged |
| Architecture | A | Clean direction, 0 cycles |
| Test Coverage | Not assessed | Integration-driven suite — structural metric invalid |
| Dead Code | B | 5 unused methods (79 convention-discovered, not counted) |
| API Surface | B | 2 overexposed service types |
| Security | A | 0 vulnerable packages |
| Documentation | D | 12/30 public APIs documented |

Overall GPA: 3.1 (B) — averaged over 7 graded dimensions.

Triage: 44 AP005 raw → all log-and-rethrow wrappers (medium); 2 AP004 real.

Priority: (1) `SystemSeeder` → `TimeProvider`, ~15 min; (2) XML docs on the 8
endpoint classes, ~1 day; (3) review the 44 catch blocks or suppress by path.
  • references/grading-rubric.md — canonical rubrics, GPA scale, report template
  • /de-sloppify — cleanup pipeline for the issues a health check surfaces
  • /security-scan — deep 6-layer scan behind Dimension 7
  • /code-review — per-change review (this skill grades the whole project)
  • /verify — pass/fail pipeline for a change set, not a graded assessment
