output-dev-upgrade-prompt-models

output-dev-upgrade-prompt-models is a skill for Claude Code from growthxai/output. It costs 81 tokens per session (1,727 once invoked), scanned A, original, Apache-2.0.

A tool for updating the model version named in .prompt files to the newest stable version within the same provider and model family.

In plain words
What is it for?
Use it for periodic project-wide model refreshes or after a long pause between framework updates.
Why use it?
It prevents prompt files from continuing to use outdated model versions while preserving deliberate choices such as provider and model tier.

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

output-dev-upgrade-prompt-models scanned grade A with 1 finding 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

**Bail loudly on a failed snapshot.** If the snapshot fetch itself returned nothing — network down, gateway shape changed, `curl` or `jq` missing — abort the run before Step 5. Do **not** continue with an empty snapshot

How it starts

The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Upgrade Prompt Models In-Place

Walks every .prompt file in a project (or scoped subtree), classifies each model into its provider+family bucket, looks up the latest stable model in that bucket via the output-dev-model-selection snapshot, and rewrites the model: line. Provider and family tier are preserved — a Haiku stays a Haiku, an Anthropic stays an Anthropic.

This skill explicitly does not swap providers or escalate tiers (eg Haiku → Sonnet). Those are deliberate human decisions handled separately.

When to invoke

  • A periodic refresh: "upgrade all my prompt models to the latest"
  • After a long break between framework updates, where dated snapshot IDs (eg claude-sonnet-4-20250514) have aged out
  • Right after creating a new project from the CLI scaffolder, to pull every templated default forward to the current best

Workflow

Step 1 — Discover

Find every .prompt file under the target scope. Default scope is the project's src/ tree; the user may scope to a single workflow.

Step 2 — Parse current model

For each file, read the YAML frontmatter (between the first pair of --- lines) and pull out provider: and model:.

Step 3 — Classify family

Match the existing model into a family bucket. Family is preserved across the upgrade.

Pattern Family
claude-opus-* anthropic-opus
claude-sonnet-* anthropic-sonnet
claude-haiku-* anthropic-haiku
gpt-*-pro openai-pro
gpt-*-mini openai-mini
gpt-*-nano openai-nano
gpt-N.M (no suffix) openai-default
gemini-*-flash-lite* google-flash-lite
gemini-*-flash* google-flash
gemini-*-pro* google-pro

If a model doesn't match any pattern, skip the file and log a warning. Do not guess.

Step 4 — Look up latest in family

For each prompt, find the latest stable model in the same family by following output-dev-model-selection — fetch its snapshot, apply its filter rules (skip preview/alpha/beta, prefer unversioned aliases), and translate the chosen id to prompt-file form.

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.
