Nokia SR (SR OS & SR Linux) router skill

Helps you inspect and operate Nokia's two network operating systems:

• SR OS (SROS) - the classic 7750 SR / 7250 IXR / 7950 XRS TiMOS-based OS.
• SR Linux (SRL) - the newer Linux-based, fully YANG-modelled OS.

They share concepts (YANG-driven config, NETCONF/gNMI) but differ in CLI, config syntax, models, and tooling. Work in this order, loading the one reference you need.

Step 1: Which NOS is it?

If you don't already know, identify SR OS vs SR Linux first - it decides every later step (models, CLI, syntax). See references/global/detecting-nos.md.

If detection is inconclusive or you are not sure, stop and ask the user to confirm which NOS it is rather than guessing - picking the wrong NOS sends you to the wrong models, CLI, and syntax.

Step 2: Get the release, then the YANG models

Rule for any config / "how do I X" question (e.g. "how do I configure X on SR OS?"): do not answer from memory. First ask the user for the software version (or confirm it from the device/config), then verify the exact paths, keywords, and syntax against the YANG models for that version before giving an answer. Paths are case-sensitive and version-dependent, so an answer that is not checked against the pinned models is a guess.

YANG paths are case-sensitive and version-dependent, so pin the release first.

• SR OS version - references/sros/version-detection.md
• SR Linux version - references/srlinux/version-detection.md

Then fetch the matching models on demand (the script is NOS-aware - first arg is the NOS, second is the version):

"${CLAUDE_PLUGIN_ROOT}/skills/nokia-sr/scripts/ensure-yang.sh" sros 25.10.R4
"${CLAUDE_PLUGIN_ROOT}/skills/nokia-sr/scripts/ensure-yang.sh" srlinux 25.10.3
"${CLAUDE_PLUGIN_ROOT}/skills/nokia-sr/scripts/ensure-yang.sh" sros latest   # newest release

SR OS needs an explicit revision (25.10.R4, not bare 25.10); SR Linux needs the three-part version (25.10.3); latest resolves the newest release from GitHub. It prints the local YANG release directory (downloading from Nokia's GitHub only if not already cached). How it works and how to search the models: references/global/yang-models.md.

Where to look

Global (both NOSes)

You need to...	Read
Tell SR OS and SR Linux apart (file, config, live device)	references/global/detecting-nos.md
Obtain / search YANG models for a release	references/global/yang-models.md
Render a YANG path tree or validate device data offline (pyang / yanglint)	references/global/yang-tooling.md
Set up the srpls language server / VS Code extension	references/global/language-server.md

SR OS (SROS)

You need to...	Read
Get the SR OS release from a device or config file	references/sros/version-detection.md
Understand info vs info flat vs info json output	references/sros/config-format.md
Push/diff config over NETCONF or navigate MD-CLI	references/sros/operate.md

SR Linux (SRL)

You need to...	Read
Get the SR Linux release from a device or config file	references/srlinux/version-detection.md
Understand SR Linux config (braced vs set flat, platform)	references/srlinux/config-format.md
Operate over gNMI / JSON-RPC / CLI	references/srlinux/operate.md

Key reminders

• Identify the NOS before anything else; SR OS and SR Linux share almost no CLI or model names.
• For any config or "how do I X" question: ask for the version first, then verify against the YANG model for that version before answering - never answer from memory.
• Pin the YANG release to the device's actual version before writing filters or templates.
• Before proposing a commit, always propose running the compare/diff first to confirm the change: SR OS compare / md-compare, SR Linux diff / commit validate. See each NOS's operate reference.
• SR OS only: check configuration-mode (classic / mixed / model-driven) before NETCONF candidate edits, and set nc:operation explicitly. See references/sros/operate.md.
• Both NOSes have a flat config form that round-trips as valid input (info flat).
