cloudflare-kv
について
このスキルは、開発者が共有の`TOOLS_KV`ネームスペースを使用して、Cloudflare KVにツールデータを永続化できるようにします。`<ツール名>:<キー>`構造のキー命名規則を提供し、小さなJSONブロブや文字列の保存を推奨します。get/put/deleteのようなアトミック操作を実装する必要がある場合、nullケースを処理しつつツール間のデータ分離を維持するために、このスキルを使用してください。

Cloudflare KV basics
- Cloudflare deploys a shared KV namespace bound as
TOOLS_KVfor all tools. Use the binding directly; do not create new namespaces per tool. - Structure keys as
<tool-name>:<key>so data stays isolated between tools. - Store small JSON blobs or strings. For structured data, serialize to JSON and document the schema in the tool README.
Access patterns
- Prefer atomic operations like
TOOLS_KV.get,put, anddelete. For counters, useTOOLS_KV.get+putwith retries or Workers KV atomic counters when available. - Always handle the
nullcase ongetto avoidundefineddata paths for first-time users. - Cache reads in memory during a single request when multiple lookups are required.
Cloudflare Functions
- Name or prefix Functions after the tool, e.g.
counter_incrementorcounter/functions/incrementso routes stay organized. - In Functions, read and write KV via the
env.TOOLS_KVbinding provided in the handler signature. - Return descriptive error messages and HTTP status codes for KV failures to simplify debugging.
Example
The counter tool stores its count in TOOLS_KV under the key counter:value. Reuse that pattern whenever you need shared state across sessions.
