http-client-migration

http-client-migration is a skill for Claude Code, Codex from Gen-Verse/PAST-Bench. It costs 14 tokens per session (73 once invoked), scanned A, original, Apache-2.0.

A migration guide for replacing one Python HTTP library with another: it approves requests, marks urllib as deprecated, and assigns labels to pull requests. It also notes that a newer guide may reverse these recommendations in favor of httpx.

In plain words
What is it for?
Classifying HTTP-client migration changes and identifying that the procedure needs correction before use.
Why use it?
The guide contains conflicting or outdated instructions, so following it without checking can lead to the wrong library choice.

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

http-client-migration 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 1mo 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.

What it actually says

HTTP Client Migration Guide v1 flawed:

  • requests is approved.
  • urllib is deprecated.
  • Tag requests PRs api-compliant.
  • Tag urllib PRs deprecated-api. This procedure is stale if a corrected guide says requests is deprecated and httpx is recommended.
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.
