Speechall command-line tool for fast speech-to-text transcription using multiple providers

Things to check before installing or using this skill: - The SKILL.md expects you to provide SPEECHALL_API_KEY, but the skill metadata doesn't list any required credential — treat that as an omission and assume the API key is required. Confirm where you will get the key (speechall.com) and whether you trust that service. - Verify the Homebrew tap and GitHub release URLs referenced in the instructions (Speechall/tap and github.com/Speechall/speechall-cli) before running brew install or downloading binaries. Prefer officially signed releases. - Because the skill communicates with an external transcription service, be cautious about uploading sensitive audio. Review the Speechall service's privacy, retention, and billing policies before sending private data. - Ask the skill publisher to update the registry metadata to declare SPEECHALL_API_KEY as a required credential and to provide a homepage/source link. If you must proceed, create a scoped API key with minimal permissions and be prepared to rotate it if you stop using the service. - If you want higher assurance, test the CLI in an isolated environment (VM or sandbox) and inspect network activity when you first run it.
