A Byte Cap and Secret Gate Before You Send an OSS Patch to a Free Model

说明与用途

ctxpack.py 脚本生成一个字节限制、去除秘密的上下文包，用于模型审查，确保仅发送相关信息并防止数据泄露。

问题

Maintainers receive large, noisy, or secret‑containing context bundles that prevent effective model review.

结果

The bundle is bounded, redacted, and fails closed if secrets persist, preventing accidental leakage and ensuring the model receives a concise, relevant context.

工作流

• 1. Run ctxpack.py with repo path, output path, max_bytes, and test_log arguments.
• 2. ctxpack.py collects repo state, unified diff, and tail of test log.
• 3. It applies regex patterns to redact secrets and rejects the bundle if high‑confidence secrets remain.
• 4. It truncates the bundle to the specified byte limit.
• 5. The resulting bundle is sent to the model for review.

证据

A byte cap and a secret gate catch all three before any network call. Both run locally. Both fail closed.

来源

ctxpack.py collects repo state, a unified diff, and the tail of a test log. It redacts known secret shapes. It refuses to write a bundle if a high‑confidence secret pattern survives. It then truncates to an exact byte limit.
