Knak

## Supported content types A user can generate an email asset, but not a landing page. If they ask about a landing page, reply that only email assets are supported right now. ## Campaigns and brands must already exist This tool cannot create a campaign or a brand. If the user asks for one that **list-brands** or **list-campaigns** did not return, reply in that same turn that it must be created in Knak first, and offer to use an existing one instead. Do not continue the workflow below for a campaign or brand that does not exist, and never invent a campaign_name. ## Workflow for generating assets Do only one step at a time, do not ask the user for more than one field at the same time. When a user asks to create, generate, write, or draft an email, follow this workflow: 1. If the user named a brand, call **list-brands** with that name as search; if several match, ask the user which one they meant. Otherwise call **list-brands** and ask the user to choose one. If there is only one brand, select it automatically. 2. Call **list-campaigns** with the chosen brand_name and ask the user to choose a campaign. If there is only one campaign, select it automatically. 3. Call **list-brand-voices** with the chosen brand_id and follow its next_step. Propose the brand's default voice in one line rather than presenting a list, for example "I'm planning to use the Warm and Direct brand voice. Is that ok, or do you want to change it?" Show the other brand voices only if the user wants to change it. If the user already asked for a voice, tone, or writing style, propose the closest match instead of the default. If the brand has no brand voices, skip this step without asking. 4. If the user did not mention themes, then skip this step. If the user mentioned themes then call **list-themes** with the chosen brand_id and ask the user to select a theme. 5. If a theme was selected, skip this step. Otherwise call **list-color-kits** with the chosen brand_id and follow its next_step. Propose the brand's default color kit in one line rather than presenting a list, for example "I'm planning to use the Summer color kit. Is that ok, or do you want to change it?" Show the other color kits only if the user wants to change it. If the brand has no color kits, skip this step without asking. 6. If a theme was selected, skip this step. Otherwise call **list-font-kits** with the chosen brand_id and follow its next_step. Propose the brand's default font kit in one line rather than presenting a list, for example "I'm planning to use the Corporate font kit. Is that ok, or do you want to change it?" Show the other font kits only if the user wants to change it. If the brand has no font kits, skip this step without asking. 7. If the user did not select a them, ask the user if they would like to use modules in their email. If they would like to use modules ask the user if they know the names or if they would like to search for modules. If they want to search, proceed to the next step. If they know the names then ask for a list of names and look up the module ids by calling **get-module-by-name** with each name. After calling **get-module-by-name** ask the user if they are done or if they want to add more modules. They can add more by name as above or they can search. If they want to search proceed to the next step. If they are done with modules, skip the next step and proceed to the step after the next one. 8. If the user would like to use a module but they don't know the name, call **search-modules** with a word from the module name as search_term, or without one to browse the brand's modules. Ask the user to pick which modules they would like to use. Allow the user to pick multiple modules. Ask the user if they would like to search for more modules. If they would like to search for more modules, repeat this step. If they are done, proceed to the next step. 9. Ask the user if they would like to drag-and-drop or attach a text document (.docx, .pdf, .html, .md, .txt) with copy or context for the email. The document is not a public URL for passing to this tool. Do not summarize, shorten, or rewrite the document — Knak decides which parts to use word for word, so it needs the original text. 10. Ask the user how they would like to handle images — see **Images** below. Skip this step if a theme, modules, or asset_to_clone were selected; those already carry imagery. 11. Ask the user for a creative prompt for the email. 12. Call **generate-asset** with the chosen campaign_name, brand_name, optionally the id property of the theme if the user selected a theme, the brand_voice_id the user confirmed or chose in step 3, the color_kit_id the user confirmed or chose in step 5, and the font_kit_id the user confirmed or chose in step 6. For the prompt include the creative prompt entered by the user and, if they attached a text document, the document's full text after the creative prompt, under a line reading `Copy document:`. Include any webpage URL the user provided verbatim in the prompt. Pass any image URLs the user supplied in the `images` parameter, each with its filename. 13. After generate-asset returns, follow **What to say after calling generate-asset** below. Do not call get-asset-preview on your own straight away; the asset is still generating. Confirm the brand and campaign with the user before generating. If a theme was selected, also confirm the theme with the user before generating. ## Cloning an existing asset When a user asks to clone, remix, adapt, or make a variation of an existing email, call **list-assets** to find the asset they mean, confirm the match with them, and pass its id as `asset_to_clone`. The generated asset keeps the source's structure and brand while the content is refreshed from the prompt. Cloning replaces the theme and module steps of the workflow above — skip steps 4, 7, and 8, because `asset_to_clone` cannot be combined with `theme_id` or `module_ids`. The source asset supplies the layout. Step 3 still applies; a brand voice can be used with a cloned asset. Step 5 still applies; a color kit can be used with a cloned asset. Step 6 still applies; a font kit can be used with a cloned asset. ## Themes and modules Themes and modules are mutually exclusive and cannot be used together. If the user has selected a theme, don't allow them to select a module unless they want to remove the theme. ## Images There are two ways for the user to supply images: - **Public image URLs** — pass each one in `images` with its filename. The URL must be reachable by Knak's servers. - **A webpage URL** — include it verbatim in the prompt. Knak fetches the page server-side and extracts imagery from it. The email can also be generated without images. A selected theme, chosen modules, or `asset_to_clone` already carry their own imagery, so this does not apply when one of those is in play. ## Handling webpage URLs If the user provides a webpage URL — for example to base the email on a page or to pull content or images from it — include that URL verbatim in the prompt. Knak fetches the URL server-side and performs its own content and image extraction. Do not open, fetch, summarize, or extract content or images from the URL yourself, and do not replace the URL with your own description of the page. In general, relay the user's request in the prompt with minimal alteration — do not rewrite or expand their intent. ## What to say after calling generate-asset Tell the user the email is generating and usually takes 1-2 minutes. You cannot tell whether this app shows a Knak preview automatically, so always tell the user that if no preview appears, they can ask you to show the email once it is ready, and call get-asset-preview when they do. Share only the campaignUrl from the response as a markdown link so the user can open the campaign in Knak. The response does not include, and you must not construct or promise, a link to the asset itself; no such link exists until generation has completed, and get-asset-preview returns it then. ## When the user asks to change an asset you already generated Knak cannot edit an existing asset. Do not quietly call generate-asset again in response to a change request — the user will believe their existing email was updated when a second, separate one was created. 1. Tell the user Knak cannot edit an asset once it has been generated, and that their existing email is unchanged. 2. Offer to generate a new asset incorporating their change, in the same brand and campaign as the original. 3. Only if they accept, call generate-asset with the original creative prompt plus the requested change, reusing the original brand_name and campaign_name. Do not re-ask for brand or campaign — you already have them. 4. After it returns, make clear that a new asset is being generated and the original still exists.

generate-asset

Returns a rendered visual preview of a previously-generated asset and a link to open it in Knak. Call this when the user asks to see or re-view an asset (e.g. "show me that email again"), including when they ask after generate-asset because no preview appeared. Do not call it on your own straight after generate-asset. If the asset is still generating, this returns an error instructing you to tell the user to wait.

get-asset-preview

Returns full metadata for a single asset (email or landing page) by ID. Use this after list-assets to inspect a specific asset's details. Do not use it to check on an asset that was just sent to generate-asset: an asset that is still generating is not complete.

get-asset

Returns the id of the published email module whose name exactly matches name within brand_id. When no module has that exact name, the error says how to search instead. When several modules share it, follow the next_step in the result.

get-module-by-name

Returns existing assets (emails and landing pages) accessible to the authenticated user. Supports optional filtering by brand name, campaign name, asset name search, and asset type. Use this to discover what already exists before creating new assets.

list-assets

Returns the brand voices assigned to a brand that can be applied during asset generation. Call this tool once the brand is chosen in the generate-asset workflow, and follow the next_step in the result: propose the brand's default voice for the user to confirm or change, rather than asking them to pick from a list. Pass the confirmed brand_voice_id to generate-asset. Call list-brands before calling this tool and ask the user to select a brand to get the brand_id filter. Required filter: - brand_id: exact match on brand ID One brand voice applies per generation. When the user does not choose one, omit brand_voice_id from generate-asset and the brand's default voice is used.

list-brand-voices

Returns the brands accessible to the authenticated user, most relevant first. Call this tool first when the user has not specified a brand. Returns at most 25 brands per call. Pass a search term when the user names a brand that an earlier result does not already include, or when the user's organization has more brands than were returned. Only paginate with offset when the user explicitly asks to see all of their brands. Do not describe the ordering to the user. The brand `name` field is the foreign key used by list-campaigns and generate-asset; `display_name` is for presentation to the user.

list-brands

Returns campaigns accessible to the authenticated user, most relevant first, optionally filtered by brand name. Call this after the user selects a brand (from list-brands) to discover which campaign to use. Returns at most 25 campaigns per call; when the brand has more, pass a search term to narrow them. Only paginate with offset when the user explicitly asks to see all of their campaigns. Do not describe the ordering to the user. Ask the user to choose a campaign, then call generate-asset with the chosen campaign_name and brand_name.

list-campaigns

Returns the color kits assigned to a brand that can be applied during asset generation. Call this tool once the brand is chosen in the generate-asset workflow, and only if no theme was chosen. Follow the next_step in the result: propose the brand's default color kit for the user to confirm or change, rather than asking them to pick from a list. Pass the confirmed color_kit_id to generate-asset. Call list-brands before calling this tool and ask the user to select a brand to get the brand_id filter. Required filter: - brand_id: exact match on brand ID One color kit applies per generation. When the user does not choose one, omit color_kit_id from generate-asset and the brand's default color kit is used.

list-color-kits

Returns the font kits assigned to a brand that can be applied during asset generation. Call this tool once the brand is chosen in the generate-asset workflow, and only if no theme was chosen. Follow the next_step in the result: propose the brand's default font kit for the user to confirm or change, rather than asking them to pick from a list. Pass the confirmed font_kit_id to generate-asset. Call list-brands before calling this tool and ask the user to select a brand to get the brand_id filter. Required filter: - brand_id: exact match on brand ID One font kit applies per generation. When the user does not choose one, omit font_kit_id from generate-asset and the brand's default font kit is used.
