dotnet-techne-synopsis

dotnet-techne-synopsis is a skill for Claude Code from Metalnib/dotnet-episteme-skills. It costs 70 tokens per session (2,672 once invoked), scanned A, original, MIT.

A static-analysis tool for .NET workspaces. It scans C# code, maps how parts depend on one another, and answers questions about the impact of changes across projects or repositories.

In plain words
What is it for?
Use it to explore dependency graphs, call relationships, endpoint and data paths, breaking changes, and the likely blast radius of a proposed .NET change.
Why use it?
It helps you see what a change may affect before editing or deploying it. A long-running mode can keep analysis available for workspaces with multiple repositories.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

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.

Security

Grade A, and why

dotnet-techne-synopsis scanned grade A with 1 finding 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 12d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/detect-tool.ps1, scripts/detect-tool.sh, scripts/install.ps1, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 257 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Synopsis - .NET Workspace Dependency & Blast-Radius Explorer

Static analysis tool that scans .NET workspaces via Roslyn, builds a dependency graph, and answers blast-radius and breaking-change queries. Supports both one-shot CLI use and long-running daemon mode for multi-repo workspaces.

Requirements

No SDK or manual installation needed. The detect script auto-downloads the correct binary on first use.

Platform Binary Downloaded from
macOS Apple Silicon bin/osx-arm64/synopsis GitHub Release synopsis-osx-arm64.tar.gz
macOS Intel bin/osx-x64/synopsis GitHub Release synopsis-osx-x64.tar.gz
Windows x64 bin/win-x64/synopsis.exe GitHub Release synopsis-win-x64.zip
Windows arm64 bin/win-arm64/synopsis.exe GitHub Release synopsis-win-arm64.zip
Linux x64 bin/linux-x64/synopsis GitHub Release synopsis-linux-x64.tar.gz
Linux arm64 bin/linux-arm64/synopsis GitHub Release synopsis-linux-arm64.tar.gz

External dependencies for auto-download:

  • macOS/Linux: curl (pre-installed) or wget
  • Windows: PowerShell 5+ (built-in System.Net.Http)

When a .NET 10 SDK is installed, the detect script downloads the slim framework-dependent build (synopsis-<RID>-slim, ~7x smaller) instead of the self-contained one. No SDK - self-contained build, no difference in behaviour.

Install (optional - build from source)

Only needed if you want to rebuild or no GitHub Release is available. Requires .NET 10+ SDK.

Bash (Linux/macOS):

./skills/dotnet-techne-synopsis/scripts/install.sh

PowerShell (Windows):

.\skills\dotnet-techne-synopsis\scripts\install.ps1

When to use this skill

Use when the user asks to:

  • Analyze blast radius of a code change
  • Map dependencies across .NET repos
  • Find what endpoints/services are affected by a change
  • Trace call chains from controller to database
  • Review cross-repo boundaries
  • Audit ambiguous/unresolved dependencies
  • Compare architecture between two snapshots (diff)
  • Classify breaking changes between two snapshots
  • Scope a PR's impact via git diff
  • Run a persistent daemon serving multiple repos under one graph
  • Find all callers of an HTTP endpoint across repos (endpoint_callers)
  • Find which services depend on a NuGet package and at what version (package_dependents)
  • Find HTTP endpoints that write to a specific database table (table_entry_points)
  • Get a service-to-service HTTP call dependency map (repo_dependency_matrix)

What ships with it

Changes

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.
