Morgana: Skill for Claude Code

.claude/skills/model-catalog-update/SKILL.md

model-catalog-update is a skill for Claude Code from mdesalvo/Morgana. It costs 66 tokens per session (2,055 once invoked), scanned A, original, Apache-2.0.

A skill for updating Morgana's catalogue of AI models, providers, and prices from the vendors' official information. It covers model availability, pricing, and deprecation data.

In plain words
What is it for?
Use it to refresh provider model lists and prices and to check that every served model has current pricing information.
Why use it?
It helps prevent model entries from becoming outdated when vendors add, change, promote, or retire models.

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

model-catalog-update 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

model-catalog-update

Every provider plugin embeds a mandatory pricing.json listing the models it serves with their prices. MorganaLanguageModel reads it and turns those dollars into dust. A tier whose model is missing from its provider's pricing.json does not start. Keeping the files current is periodic maintenance: vendors add models, change prices, end promotions and retire models.

Ollama's catalogue holds only the cloud models that ollama.com hosts and bills per token. A local model costs nothing to Ollama's account, so it is never catalogued and a tier running one declares its own Pricing, zero or the deployment's hosting cost. The same holds for any provider that hosts models under names its customers choose (Azure OpenAI deployments, for instance). A deployment that needs a model before the next release catalogues it, or pays a negotiated price, declares Pricing on its tier too: the catalogue is the default that such a tier overlays. Where a source URL has moved, follow the vendor's redirect. Prices and model ids come only from these official pages, never from memory, third-party aggregators or gateways.

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.
