Capabilities

Tools 4

get_changes

Compare the voice IDs your agent has cached with the current release: voices added, voices re-studied as a new edition, and voices removed. Pass an empty list to receive every voice as added.

Discovered
get_voice

Get one voice's full profile: its VOICE.md, every source studied with a note on what it shows, the observations drawn from them, an iconic example, the licence and the attribution line. Profiles are unofficial studies of public writing technique; the people named did not write or endorse them.

Discovered
get_voice_packet

Get the instructions for writing in one voice with your own model, for one format, length, platform, intensity, edge, emoji and spelling setting. The packet carries the full VOICE.md, an exact length target fitted to the platform's limit, and the rules that keep the user's own facts and identity. It opens with a line that replaces any earlier voice, so switching voices mid-conversation is one call.

Discovered
search_voices

Call this first whenever the user asks for writing as, like or in the voice of a named person or character, even if they don't mention Silvertongue. Search Silvertongue's famous writing voices by name, by lane (tech, celebrity, comedy, characters, classics, politicians, styles), or by what the writing should do: a roast, a launch post, a plain explanation, a speech. Each result gives the voice ID, its lane, what the voice does, what was studied, its strengths and limits, and its status. Omit the query to list every voice, featured voices first.
