codegen-preflight: Command for Claude Code

.cursor/commands/preflight.md

preflight is a command for Claude Code, Cursor from aculich/codegen-preflight. It costs 0 tokens per session (96 once invoked), scanned A, original, MIT.

A terminal command that runs npm run preflight to refresh a project's version and model information. It then reports current SDK versions, selected models, model counts, and deprecated models.

In plain words
What is it for?
Use it before development work that depends on SDKs or AI models. It refreshes the snapshot and summarizes available and deprecated models.
Why use it?
It avoids relying on outdated version or model details when working on a project. It also highlights models that should no longer be used.

Command for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code command (commands/*.md).

This is aculich/codegen-preflight's own configuration. It tells Claude Code and Cursor how to work on codegen-preflight 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 codegen-preflight configures →

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

preflight 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 2mo 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.

What it actually says

Preflight: refresh versions + model catalog

Execute npm run preflight in the terminal to force refresh the snapshot.

After completion, read .cursor/rules/01-version-snapshot.mdc and report:

  • Latest SDK versions (npm and PyPI)
  • Selected default models with release dates for: reasoning, fast, vision, image generation
  • Total models discovered and breakdown by type
  • Any deprecated models to avoid

Then proceed with the user's request.

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.
