dotnet-sherlock-mcp: Instructions file for Codex

AGENTS.md

dotnet-sherlock-mcp AGENTS.md is an instructions file for Codex, OpenCode from jcucci/dotnet-sherlock-mcp. It costs 886 tokens per session, scanned A, original, MIT.

Repository instructions for a .NET 9 project called dotnet-sherlock-mcp. They describe its folders, C# coding conventions, build and test commands, and how to run or install the tool.

In plain words
What is it for?
Use them when developing in the repository, running its build or tests, changing C# code, starting the MCP server, or installing the command-line tool.
Why use it?
They give contributors a shared way to build, test, format, and organize the project. This reduces mistakes when changing the server, runtime, tests, or examples.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is jcucci/dotnet-sherlock-mcp's own configuration. It tells Codex and OpenCode how to work on dotnet-sherlock-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything dotnet-sherlock-mcp configures →

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-sherlock-mcp AGENTS.md 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 22d 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.

Repository Guidelines

Project Structure & Module Organization

  • src/Sherlock.MCP.slnx: Solution file (XML format).
  • src/server: MCP server (Sherlock.MCP.Server) and entry point.
  • src/runtime: Core analysis services and contracts (Sherlock.MCP.Runtime).
  • src/unit-tests: xUnit tests (e.g., MemberAnalysisServiceTests.cs).
  • src/integration-tests: End-to-end MCP stdio protocol tests that launch the server.
  • src/benchmarks: BenchmarkDotNet benchmarks (run on demand; see src/benchmarks/README.md).
  • src/example: Minimal console example.
  • src/docs: Roadmap and supporting docs.

Build, Test, and Development Commands

  • dotnet restore && dotnet build src/Sherlock.MCP.slnx: Restore and build (net8.0, net9.0 and net10.0).
  • dotnet run --project src/server/Sherlock.MCP.Server.csproj: Run MCP server over stdio.
  • dotnet test src/unit-tests/Sherlock.MCP.Tests.csproj: Run unit tests.
  • dotnet test --collect:"XPlat Code Coverage": Run tests with coverage (coverlet).
  • ./tool-install.sh / ./tool-uninstall.sh: Pack and install/uninstall the global tool (sherlock-mcp).

Coding Style & Naming Conventions

  • Multi-targets .NET 8, 9 and 10; nullable enabled, implicit usings on; prefer file‑scoped namespaces.
  • Indentation: 4 spaces; wrap at ~120 chars where practical.
  • Naming: PascalCase for types/methods/properties; camelCase for locals/parameters; interfaces start with I.
  • Prefer expression-bodied members when clear; use named parameters when argument meaning isn’t obvious.
  • Keep code self‑documenting; avoid redundant inline comments. Braces optional for single‑line blocks if readability holds.

Whitespace & Formatting

  • Use a single blank line between the using block and the file‑scoped namespace.
  • Use a single blank line after the file‑scoped namespace before the first type/member.
  • Keep exactly one blank line between consecutive members inside a type (methods, properties, events, nested types) to separate logical units.
  • Within longer methods, group related steps and separate them with a single blank line (setup, processing, return) — no multiple consecutive blank lines.
  • Ensure files end with a trailing newline; avoid trailing whitespace on lines.
  • Maintain one top‑level type per file; nested types are allowed within their parent file.

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.
