code-copilot-team: Instructions file for GitHub Copilot

adapters/github-copilot/.github/instructions/stack-constraints.instructions.md

code-copilot-team stack-constraints.instructions.md is an instructions file for GitHub Copilot from gosha70/code-copilot-team. It costs 478 tokens per session, scanned A, original, MIT.

A set of rules for choosing technology versions, installing dependencies, and handling compatibility problems in software projects.

In plain words
What is it for?
Use it when selecting framework, runtime, database, or UI-library versions, installing new packages, testing builds, or deciding whether to downgrade a dependency.
Why use it?
It helps prevent unstable packages, missing runtime dependencies, and avoidable version conflicts.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file. Also seen: mentions CLAUDE.md.

This is gosha70/code-copilot-team's own configuration. It tells GitHub Copilot how to work on code-copilot-team 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 code-copilot-team 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

code-copilot-team stack-constraints.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 4d 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.

Stack Constraints

Rules for managing dependency versions and technology choices across all project types.

Version Pinning Policy

When starting a new project, prefer stable, well-documented versions over bleeding-edge:

  • ORM / database tools — use latest stable, not pre-release (e.g., avoid beta/canary/rc).
  • Framework — use LTS or latest stable release.
  • Language runtime — use latest stable (not beta/rc).
  • UI libraries — use latest stable release.

Check package documentation for "stable" vs "experimental" badges before adopting.

Dependency Installation Protocol

When agents create code requiring new packages:

  1. Agents should install dependencies as part of their task — if they have Bash permission, they must install what they import.
  2. If an agent lacks permission, pause and instruct the user to install manually before continuing.
  3. Always test the build after new dependencies — run the dev server, not just the type checker. Static analysis doesn't catch missing runtime packages.
  4. Check for peer dependency warnings — these often surface as runtime crashes, not compile errors.

When to Downgrade

Downgrade from a newer version to a stable one when:

  • CLI or build tooling breaks (common with major version bumps of ORMs, bundlers, and frameworks).
  • Runtime behavior changes unexpectedly from documented behavior.
  • Community plugins/extensions don't yet support the new version.
  • Error messages reference features marked "experimental" or "early access."

Document the version pin and the reason in the project CLAUDE.md or a DECISIONS.md so future contributors know why.

Stack-Specific Notes

Add version constraints relevant to your project in the project-level CLAUDE.md. For example:

## Stack Constraints
- ORM: Prisma 6.x (7.x has breaking CLI changes as of Feb 2026)
- Runtime: Node 20 LTS (not 22 — some deps don't support it yet)
- Framework: Next.js 14 stable (not 15 canary)

This keeps global rules generic while allowing each project to pin its own versions.

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.
