Prompt Studio
Step-by-step prompt builder for Hermes Desktop (F4): option cards per step with AI suggestions, then an AI-written final prompt sent to or placed in the composer through host.composer (Hermes Desktop 0.21.5+). Tuned for Claude Opus 5.5, Claude Sonnet 5.5 and GPT-6 Astra. AI calls go through its own auxiliary task (auxiliary.prompt_studio) via the dashboard plugin API; sends no temperature. No external network beyond the configured provider; preferences in ctx.storage.
Good to know before installing
On opening in an existing chat (default on, toggle in Studio Settings) it reads the last 8 user/assistant turns (plus any compaction summary) of that session from state.db, redacts secrets and sends up to 8k chars to the configured auxiliary model for a short summary used in step suggestions; draft and form answers go to the same auxiliary model; no other network.

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install prompt-studio - Said no? Turn it on later:
hermes plugins enable prompt-studio - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
