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 | $0.00052 | $0.00978 |
| Opus 5.5 | $0.00021 | $0.00391 |
| Sonnet 5.5 | $0.00010 | $0.00196 |
| Haiku 4.5 | $0.00005 | $0.00098 |
Grade A, and why
mcaf-dotnet-code-analysis 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.

MCAF: .NET Code Analysis
Trigger On
- the repo wants first-party .NET analyzers
- CI should fail on analyzer warnings
- the team needs
AnalysisLevelorAnalysisModeguidance
Value
- produce a concrete project delta: code, docs, config, tests, CI, or review artifact
- reduce ambiguity through explicit planning, verification, and final validation skills
- leave reusable project context so future tasks are faster and safer
Do Not Use For
- third-party analyzer selection by itself
- formatting-only work
Inputs
- the nearest
AGENTS.md - project files or
Directory.Build.props - current analyzer severity policy
Quick Start
- Read the nearest
AGENTS.mdand confirm scope and constraints. - Run this skill's
Workflowthrough theRalph Loopuntil outcomes are acceptable. - Return the
Required Result Formatwith concrete artifacts and verification evidence.
Workflow
- Start with SDK analyzers before adding third-party packages.
- Enable or document:
EnableNETAnalyzersAnalysisLevelAnalysisMode- warning policy such as
TreatWarningsAsErrors
- Keep per-rule severity in the repo-root
.editorconfig. - Use
dotnet buildas the analyzer execution gate in CI. - Add third-party analyzers only for real gaps that first-party rules do not cover.
Bootstrap When Missing
If first-party .NET code analysis is requested but not configured yet:
- Detect current state:
dotnet --inforg -n "EnableNETAnalyzers|AnalysisLevel|AnalysisMode|TreatWarningsAsErrors" -g '*.csproj' -g 'Directory.Build.*' .
- Treat SDK analyzers as built-in functionality, not as a separate third-party install path.
- Enable the needed properties in the solution's MSBuild config, typically in
Directory.Build.propsor the target project file:EnableNETAnalyzersAnalysisLevelAnalysisModewhen needed- warning policy such as
TreatWarningsAsErrors
- Keep rule-level severity in the repo-root
.editorconfig. - Run
dotnet build SOLUTION_OR_PROJECTand returnstatus: configuredorstatus: improved. - If the repo intentionally defers analyzer policy to another documented build layer, return
status: not_applicable.
What ships with it
1 file 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.

mcaf-dotnet-code-analysis is a skill published in the GitHub repository managedcode/dotPilot (25 stars, last pushed 6mo ago), licensed MIT. It adds 52 tokens to every session and 978 once invoked, about $0.0002 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 2026-08-30.
