api-versioning-strategy

api-versioning-strategy is a skill for Claude Code from curiositech/windags-skills. It costs 74 tokens per session (3,540 once invoked), scanned A, original, no licence file.

A guide to choosing and running a way to version HTTP APIs, which are web interfaces that programs use to communicate. It covers date-based versions, version notices, URL and header choices, and converting between versions.

In plain words
What is it for?
Use it when designing an API versioning policy, changing existing endpoints, planning deprecations, or keeping different client versions working.
Why use it?
It helps prevent changes to an API from unexpectedly breaking existing client programs. It also explains how to warn clients before an old version is removed.

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

api-versioning-strategy 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.

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 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.
