description	Authoritative reference to the upstream Nim language, compiler, and standard library (github.com/nim-lang/Nim). Use when you need ground-truth on Nim std modules, --mm:orc semantics, syntax, or pragmas for Maestro's TUI frontend.

Nim Upstream Skill

Ground-truth reference for the Nim language and standard library used by Maestro's frontend/.

Authoritative source

• Repo: [e-mail]:nim-lang/Nim.git — https://github.com/nim-lang/Nim
• Use it (via github_repo / fetch_webpage) to confirm std/* module APIs (json, strutils, os, streams, unittest), pragma behavior, and --mm:orc memory semantics.

When to apply

• Verifying a Nim std API signature or a language construct (templates, macros, proc/func).
• Questions about ORC memory management, value vs ref types, or defer lifecycle.
• Formatting/build questions: nph, nimble, Nim ≥ 2.0 features.

How to use it in Maestro

• Prefer local conventions first: the tatui-frontend skill and .github/instructions/nim-frontend.
• The frontend targets Nim ≥ 2.0 with --mm:orc; ignore pre-2.0 or GC-specific upstream guidance.
• Cite exact upstream paths/permalinks when relying on upstream behavior.

Guardrails

• The TUI is a thin renderer: no orchestration logic in Nim; the draw is a pure function of state.
• Frontend Nim only consumes Tatui widgets; it does not reimplement TUI primitives.
