dotnet-skills: Instructions file for Codex

AGENTS.md

dotnet-skills AGENTS.md is an instructions file for Codex, OpenCode from Postpartum-genushyacinthus29/dotnet-skills. It costs 9,366 tokens per session, scanned A, original, MIT.

A rulebook for maintaining a catalogue of .NET development skills, coordinating coding agents, and updating the catalogue from official .NET releases and documentation. .NET is Microsoft's platform for building applications and libraries.

In plain words
What is it for?
It helps maintain .NET skill entries, repository-owned agents, release-monitoring automation, and the rules for where executable code may live.
Why use it?
It keeps the repository focused on distributing and maintaining skills instead of becoming an unrelated application, while defining how its parts fit together.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: reads ~/.codex or $CODEX_HOME, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is Postpartum-genushyacinthus29/dotnet-skills's own configuration. It tells Codex and OpenCode how to work on dotnet-skills 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-skills 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-skills AGENTS.md 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 11d 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.

Purpose

This file defines how AI agents work in this repository.

  • Root AGENTS.md holds the global workflow, repository structure, release and automation policy, and skill-catalog maintenance rules.
  • This repository currently uses only the root AGENTS.md; add a nearer local AGENTS.md only when a subtree needs stricter or more specialized rules.
  • The repository has three equally important responsibilities:
    1. Maintain a high-quality skills/ catalog for modern and legacy .NET.
    2. Maintain repo-owned orchestration agents/ that route broader tasks into the right skills or narrower agents.
    3. Maintain automation that watches official upstream releases and documentation so the catalog can be refreshed when the ecosystem changes.

If this repository contains executable code, it must exist only to distribute or install the skill catalog itself, for example as a publishable dotnet tool. Do not turn this repository into a general application or unrelated tooling codebase.

All repository-facing documentation and skill content should be written in English. Follow official or documented agent standards where they exist; do not present a repo-local adapter as if it were a universal standard.

Solution Topology

  • Solution root: .
  • Areas with specialized responsibilities:
    • agents/: top-level orchestration agents that sit above the skill catalog, one folder per agent
    • skills/: canonical skill catalog
    • tools/ManagedCode.DotnetSkills/: publishable dotnet-skills installer tool
    • scripts/: catalog generation and upstream-watch automation
    • .github/workflows/: CI, release, and scheduled automation
  • Local AGENTS.md files currently present: none

Rule Precedence

  1. Read the root AGENTS.md first.
  2. If a local AGENTS.md is later added for a subtree, read the nearest one before editing that area.
  3. Apply the stricter rule when both files speak to the same topic.
  4. Local AGENTS.md files may refine or tighten root rules, but they must not silently weaken them.
  5. If a subtree needs a durable exception, document it explicitly in the nearest local AGENTS.md or another canonical repo document.

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.
