preflight

preflight is a skill for Codex from ConnorGriffin/skills. It costs 50 tokens per session (1,089 once invoked), scanned A, original, no licence file.

A preparation check for a plan, specification, work order, or process document before review or execution. It verifies the facts, tests the first hour of work, and gathers rules in one place.

In plain words
What is it for?
Use it to prepare a draft for review or implementation by grounding its facts, testing its opening steps, and consolidating its rules.
Why use it?
It prevents review from starting with unverified assumptions or unclear instructions. Early practical checks reveal whether the proposed work can actually get started.

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 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 4d 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
