model-registry-refresh

model-registry-refresh is a skill for Claude Code from VincentChuWaiChow/vanguard-frontier-agentic. It costs 79 tokens per session (1,878 once invoked), scanned A, original, Apache-2.0.

A procedure for checking and updating the list of approved AI model names and reasoning settings in a repository. It uses official documentation as evidence for each entry.

In plain words
What is it for?
Use it when a model is missing from the registry, when a provider changes its models, or when the registry has not been reviewed for about three months.
Why use it?
It avoids failed policy checks and prevents model names or settings from being accepted based only on guesses or outdated information.

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-registry-refresh 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 2d 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.

Model Registry Refresh

Doctrine

catalog/model-registry.json is the single source of truth scripts/model-policy.mjs fails closed against. Every model name and reasoning-effort value it accepts must trace to official documentation with a citation — never to memory, never to a plausible-sounding guess at a slug. This skill is the repeatable workflow for keeping that registry accurate without letting research cost dominate the orchestrator's context.

When to run

  • npm run model-policy:check fails with an error naming a model "not in the verified model registry" — the registry is missing a model the policy (or an operator) wants to use.
  • A provider (OpenAI, Anthropic, Cursor) ships new models or retires old ones and the catalog needs to reflect current reality.
  • Quarterly staleness check — last_refreshed in catalog/model-registry.json is more than ~3 months old.

Step 1 — delegate research to Haiku Explore agents

Fan out one Haiku Explore agent per harness (or per namespace, for codex) using the Context7 MCP tools (mcp__Context7__resolve-library-id then mcp__Context7__query-docs) plus official docs URLs already cited in the registry. Each research task must:

  • Ask for exact slugs/IDs, not families — gpt-5.5 not "the gpt-5 line".
  • Ask for reasoning-effort support per model, not per harness — some models in a family predate newer effort levels (see o1/o3/o4-mini lacking none/minimal/xhigh in the current registry).
  • Ask for failure-mode evidence — what error shape a bad model name or unsupported effort actually produces (HTTP status, error code/type), so docs/model-policy-matrix.md's failure table stays accurate.
  • Require a source citation per claim — a Context7 library ID + section, or an official docs URL. A finding without one is not actionable.
  • Require an explicit UNVERIFIED flag on anything the agent could not confirm from a primary source (e.g. inferred from a changelog mention, or contradicted between two docs). Do not let an agent silently round an uncertain claim into a confident one.
