Skill: Services Review

Use this skill when reviewing or implementing changes in src/services/.

Objectives

• Preserve single-responsibility boundaries between services.
• Check whether a change belongs in an existing service before adding a new one.
• Confirm that changes to fragment structure, encryption format, or JSON index semantics are documented.

Checklist

1. Identify which exported service owns the behavior.
2. Confirm whether public API or constructor signatures change.
3. Update or add Jest tests under __tests__/.
4. Update docs/API.md or docs/ARCHITECTURE.md when behavior changes.

Repository Facts

• VideoFragmenter reads files in chunks via streams.
• FragmentEncryptor uses AES-256-GCM and wallet-derived keys per fragment index.
• EthereumWallet derives keys from a mnemonic and BIP44 path.
• IPFSUploader uses ipfs-http-client.
• IndexManager persists fragment metadata and status.
