ai-workshop: Instructions file for GitHub Copilot

.github/instructions/snapshot-code.instructions.md

ai-workshop snapshot-code.instructions.md is an instructions file for GitHub Copilot from dotnet-presentations/ai-workshop. It costs 360 tokens per session, scanned A, original, MIT.

A set of instructions for maintaining committed .NET workshop code snapshots. A snapshot is the checked-in result of following a lab's README, including its commands, packages, settings and observable behavior.

In plain words
What is it for?
Use it when changing .NET sample projects, package references, configuration, README steps or the build and validation process for workshop material.
Why use it?
It prevents the teaching instructions and sample code from drifting apart. It also keeps secrets, generated deployment files and build outputs out of snapshots.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is dotnet-presentations/ai-workshop's own configuration. It tells GitHub Copilot how to work on ai-workshop 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 ai-workshop 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

ai-workshop snapshot-code.instructions.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 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.

What it actually says

Workshop code snapshots

  • Treat each snapshot as the result of following its lab README, not as an independent sample. Keep commands, package references, configuration names, source code, and observable behavior aligned in both directions.
  • Preserve the workshop's scaffold-first flow. Projects taught as generated must begin with the documented dotnet new command; record required package updates as explicit attendee steps.
  • Read the affected project files and docs/instructor/DEPENDENCY_POLICY.md before changing package versions. Preserve security overrides, compatibility boundaries, coordinated sets, and cross-project consistency documented by the surrounding lab.
  • Store credentials in user secrets or the configuration mechanism taught by the lab. Never add real endpoints, keys, generated .azure/ state, or deployment output to a snapshot.
  • Do not commit bin/, obj/, .vs/, or TestResults/ directories.
  • Build every affected target in Release and treat warnings as regressions. Use .github/workflows/dotnet-build.yml for the authoritative SDK and target list.
  • Use the workshop-testing skill when the task requires reproducing a snapshot from the README or validating the lab as an attendee.
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.
