modelRegistry

modelRegistry is a skill for Claude Code from AlirezaSoltaniJazi/Skillnir. It costs 140 tokens per session (2,330 once invoked), scanned A, original, MIT.

A maintenance guide for an AI model registry: a list of model names, aliases, tiers, defaults, and backend command-line setup hints. It requires checking current authoritative sources because model offerings change.

In plain words
What is it for?
Use it when adding or retiring models, correcting model metadata, updating backend install or login help, or checking that the picker and tests agree.
Why use it?
It helps prevent outdated or incorrect model identifiers and login instructions from reaching a model picker or installation guide.

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

modelRegistry 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-model-registry.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Before You Start

Read LEARNED.md first. It records which sources were reachable, account/tier limits found on this machine, and past corrections. Entries there override defaults here.

Announce skill usage. Say "Using: modelRegistry skill" at the very start of your response before doing any work.

Never answer model questions from memory. Model IDs are exact strings and the lineup changes often; a remembered ID is how a broken model reaches the picker. Always check a live source first — see model-sources.md.

When to Use

  1. Checking whether the model selection list is still current
  2. Adding a newly released model, or retiring one
  3. Fixing a wrong/missing model ID, alias, tier, or default
  4. Reviewing or updating the CLI install / login / verify hints
  5. Auditing that the picker, CLI, and tests all agree

Do NOT Use

  • Changing which model a run uses right now — that's the Settings page or the Switch Model dialog, not a code change.
  • Adding a new skill scope or prompt template — use skillnir (different registry, different file).
  • Backend behavior (effort, thinking, subprocess flags) — use backendEngineer; this skill owns the catalog data, not the execution path.

What This Skill Owns

Concern File
Model selection list (all 4 backends) src/skillnir/backends.py → BACKENDS[...].models
Default model + alias resolution src/skillnir/backends.py → default_model, resolve_model_id()
CLI install / login / verify hints src/skillnir/ui/components/welcome_dialog.py → _CLI_SETUP_INFO
Alias + catalog invariants (tests) tests/test_backends.py

What ships with it

9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
