openstory: Skill for Claude Code

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

update-model-versions is a skill for Claude Code from openstory-so/openstory. It costs 125 tokens per session (2,725 once invoked), scanned C, original, MIT.

A maintenance routine for checking whether the project’s configured AI models have newer successor versions.

In plain words
What is it for?
Use it to find verified model replacements and prepare focused updates for text, image, video, audio, and BytePlus model registries.
Why use it?
It helps prevent the project from continuing to use outdated model versions or mismatched identifiers for different service routes.

This is openstory-so/openstory's own configuration. It tells Claude Code how to work on openstory itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything openstory configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 C, and why

update-model-versions scanned grade C with 2 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Update model versions

Our model registries are the single source of truth:

Class File Export
Text (OpenRouter) src/models/models.config.ts SCRIPT_ANALYSIS_MODELS
Image (fal.ai) src/models/models.ts IMAGE_MODELS
Video / motion (fal.ai) src/models/models.ts IMAGE_TO_VIDEO_MODELS
Audio (fal.ai) src/models/models.ts AUDIO_MODELS
BytePlus Ark ids src/models/models.ts byteplusId fields

A model with a native BytePlus route (#1157) carries two ids under one key: the fal endpoint id AND a byteplusId (Ark model id). A version bump must move BOTH — bumping only the fal id silently routes Ark traffic to the older model (and vice versa), and the pricing alias (applyBytePlusRouteAliases) would quote the wrong rate for whichever id was left behind.

The goal each run: detect newer versions → verify each is a real successor → open a focused PR that bumps it → leave everything green.

npm dependencies are out of scope. Bumping @tanstack/ai* (or any other npm package) is Dependabot's job, not this routine's — the detector no longer checks the npm registry. Don't open model-freshness PRs or issues for package versions.

1. Detect candidates

bun models:check          # human-readable report
bun models:check --json   # { ok, errorCount, hasUpdates, models[] }

scripts/check-model-updates.ts reads the registries and queries public, unauthenticated catalogs (fal.ai /api/models, OpenRouter /api/v1/models). BytePlus Ark ids are checked offline against the installed @tanstack/ai-byteplus model catalog — Ark publishes no unauthenticated catalog, so the adapter's lists are the freshness source. Everything else is HTTP-only so it runs anywhere — no FAL_KEY or MCP needed. Behind a proxy it routes through curl (Bun's fetch can't traverse a TLS-intercepting proxy), so curl must be on PATH in that case.

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.

update-model-versions is a skill published in the GitHub repository openstory-so/openstory (607 stars, last pushed yesterday), licensed MIT. It adds 125 tokens to every session and 2,725 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
