A tool's own minimum provider confidence belongs in its definition, or in the definition of its collection, not here. - `app/MindWork AI Studio/Tools/ToolCallingSystem/ToolSettingsOptionSources.cs` when a tool setting offers a fixed choice the app maintains, such as languages.

Tool settings need no code to be centrally manageable: an organization addresses them by `"."` in `DataTools.LockedToolSettings` or `DataTools.DefaultToolSettings`. Tool implementations must treat model-provided arguments as untrusted input. Validate settings and arguments, protect secrets with `SensitiveTraceArgumentNames`, use `ToolExecutionBlockedException` for intentional policy blocks, and check provider confidence before returning sensitive data to the model. +A tool which belongs to a preview feature returns false from `IToolImplementation.IsAvailable` while the preview is switched off; the registry then leaves it out of every list, every request, and the token count, so no component has to check that preview for the tool. Every tool declares in `IToolImplementation.OutboundData` where its arguments go: a chat which read from a mailbox keeps the tools whose data goes further than the mailbox allows from being offered and from running, see `ToolSelectionRules.IsOutboundDataAllowed`. A tool which brings content of a mailbox into the chat raises `ToolExecutionResult.RequiredOutboundDataRestriction`, next to `RequiredProviderConfidence` and `RequiredDataSecurity`. "Searching Mailboxes" in `documentation/Tools.md` explains the mail tools. + A tool which offers itself from the context of a chat instead of being selected, such as `semantic_search`, sets `Activation = ToolActivation.CONTEXT` and tailors its function to each request in `ResolveFunctionAsync`. Code which decides something on behalf of a request — whether the classic RAG process steps back, say — asks `ToolRegistry.GetOfferBlockReasonAsync` or `ToolRegistry.GetEffectiveRetrievalModeAsync` with the provider settings of the request (`IProvider.CreateSettingsProvider`), never a check of its own: two answers which drift apart leave a chat searching nothing or twice. ## Model Capabilities @@ -221,6 +224,56 @@ RAG is available as a beta preview feature.

AI Studio keeps a local index of your mails, and the AI can search, read, and count them. It works with every mail provider that offers IMAP, among them Gmail, GMX, WEB.DE, iCloud Mail, and an Exchange server of your organization with IMAP switched on. Microsoft 365 and Outlook.com follow later because they require a sign-in with Microsoft. To try it, open the app settings, allow preview features down to prototype, and enable both RAG and mailboxes. +- Added the number of indexed mails to the information page, next to the number of indexed files. +- Added tool collections for tools that only make sense together. Search Mails, Read Mail, and Count Mails appear as one entry, Mailboxes: you select them together, they require one confidence level, and IT departments switch them off together. +- Added organization-wide management for mailboxes. IT departments can prevent users from adding mailboxes, and they can rule out the less strict choices of where a chat may send data after reading mails. +- Added the mail servers of your organization to the setup of a mailbox. IT departments can name them in a configuration, and the mailbox dialog lists them before the public mail providers, with a hint on the username and a link to their instructions. +- Added a way for IT departments to allow mailboxes only on the mail servers of your organization. AI Studio then connects to no other server, and the AI no longer reads a mailbox somebody added elsewhere. +- Improved the Read Web Page tool. When you have not allowed the AI to choose web addresses freely, the tool now refuses every address that does not appear in your chat or in what the tools returned, instead of only asking the AI not to read it. +- Fixed a warning about the confidence level that stayed in the dialog for adding a local data source, even after you chose an embedding provider that meets it. The dialog now checks again whenever you change either of them, so a warning also appears when you switch to a provider that falls short. +- Fixed two confidence levels sharing the same name in the German user interface. Moderate is called "Mäßig" again, and Medium stays "Mittel". +- Fixed renaming an external data source (ERI server) leaving its secret behind under the old name in the keychain of your operating system. \ No newline at end of file diff --git a/app/MindWork AI Studio/wwwroot/images/provider-icons/README.md b/app/MindWork AI Studio/wwwroot/images/provider-icons/README.md index 4bf0d75b..0f9b501f 100644 --- a/app/MindWork AI Studio/wwwroot/images/provider-icons/README.md +++ b/app/MindWork AI Studio/wwwroot/images/provider-icons/README.md @@ -2,9 +2,12 @@ All provider icons are shipped with AI Studio and loaded locally.

The export reads saved, effective settings, including organization-managed values. It does not save settings or change the keyring. Missing values are omitted, explicitly empty non-secret values are preserved, and implicit runtime defaults are not added. Incomplete configurations can be exported so that you can finish them in Lua.

Wherever your configuration names tools — `DataTools.DisabledToolIds`, `DataTools.MinimumProviderConfidenceByToolId`, chat templates, and document analysis policies — use the ID of the collection for them. The ID of one of its tools counts for the whole collection, so naming it switches off the whole collection or sets its confidence; of several levels set for a collection and its tools, the highest applies.

AI Studio synchronizes it every 16 minutes and keeps a local index of it, which the tool collection `mailboxes` searches, reads, and counts. + +These settings decide how your organization uses them: + +| Setting | Effect | +|---|---| +| `DataApp.AllowUserToAddMailbox` | `false` keeps users from adding mailboxes. Mailboxes they added before stay. | +| `DataMailboxes.MinimumOutboundDataRestriction` | The least strict outbound data restriction a mailbox may have, see below. | +| `DataMailboxes.AllowOnlyOrganizationMailServers` | `true` allows mailboxes only on the mail servers you offer, see below. | +| `DataTools.DisabledToolIds` with `mailboxes` | Keeps the AI from reading any mailbox. | + +Every mailbox also requires a provider confidence of its own, from `VERY_LOW` to `HIGH`. The chat provider and the embedding provider have to meet it before they see a mail. An IMAP server whose certificate chains to your private root CA works with the same settings as HTTPS, see [Custom root certificates for Flatpak deployments](#custom-root-certificates-for-flatpak-deployments). + +### Where a chat may send data + +Mails come from strangers and may contain instructions meant for the AI. That is why each mailbox decides where a chat may still send data once it has read mails from it: + +| Value | What the chat may still do | +|---|---| +| `ONLY_CONFIGURED_SERVICES` | Use only services configured in AI Studio, such as the mailbox itself or your Confluence. New mailboxes start here. | +| `ONLY_LINKS_FROM_CHAT` | Also read web pages whose addresses stand in the chat, written by the user or returned by a tool. No web search, and no addresses the AI chooses itself. | +| `UNRESTRICTED` | Use every tool the user selected. | + +With `DataMailboxes.MinimumOutboundDataRestriction`, you rule out the less strict levels. A mailbox set to one of them gets your level whenever its mails reach a chat, and its dialog no longer offers them. A chat which read mails before keeps the level it got then, until it reads mails again. + +### Mail servers of your organization + +`CONFIG["MAILBOX_PROVIDERS"]` offers your own mail servers in the mailbox dialog, ahead of the well-known public providers. Each entry names the server with its host, port, and encryption, and may add a hint on the username and a link to your instructions; users still sign in with their own username and password. A configuration may define several mail servers, and those of all your configurations are offered together. `plugin.lua` lists the fields. + +With `DataMailboxes.AllowOnlyOrganizationMailServers`, AI Studio connects to no other IMAP server. Before every connection, it compares the host of the mailbox with the hosts of your mail servers; port and encryption make no difference. A mailbox somebody added on another server before stops synchronizing at once, the embeddings page says why, and the AI no longer reads it. Its local index stays, so the mailbox comes back as it was, should you allow its server again. Switch it on together with your first mail servers, and nobody gets to add a mailbox elsewhere at all. + ## Letting users provide their own API key Sometimes you want to hand out a preconfigured provider -- a fixed host, model, and instance name diff --git a/documentation/Tools.md b/documentation/Tools.md index a99c6af0..f5db06da 100644 --- a/documentation/Tools.md +++ b/documentation/Tools.md @@ -8,11 +8,13 @@ A tool is a single `IToolImplementation` class in `app/MindWork AI Studio/Tools/ The provider only sees local tools that are +- present in this installation, which a tool of a preview feature only is while the preview is switched on, and - available for the current component and - selected by the user or defaults, or offering themselves from the context of the chat, and - supported by the model and - configured correctly and - allowed by the provider confidence rules and +- allowed by the outbound data restriction of the chat and - able to offer something in this request. ## Provider API Shapes @@ -53,6 +55,8 @@ User-visible names, descriptions, and icons come from the implementation's own m Use stable lower-case IDs with underscores, and keep `Id`, `ImplementationKey`, and `Function.Name` identical unless there is a clear compatibility reason not to.

Searching mails without being able to read the ones found gets in the way, and reading them with less trust than the search asks for would protect nothing. Such tools form a collection: people select it as one entry, it needs one minimum provider confidence, and an organization switches it off as one. The model still sees each of its tools on its own and calls each by its name. + +A collection is an `IToolCollection` class next to its tools, registered in `Program.cs`. It states its `ToolCollectionDefinition`: its ID, the IDs of its tools in the order they are listed, its minimum provider confidence, and a description for a model which picks the tools of an assistant. Its name, description, and icon come from its own members, so they can be translated. Whether it exists right now follows from its tools: it disappears with the last of them, e.g., while their preview is switched off. `ToolRegistry` registers collections after the tools and leaves out what it cannot accept: a collection taking the ID of a tool, a tool which is not registered or which offers itself from the context of a chat, and a tool another collection claimed first. + +Every tool belongs to exactly one collection. A tool which belongs to no declared collection forms one of its own under its own ID. That is why the settings which used to name tools need no migration: `DisabledToolIds`, `MinimumProviderConfidenceByToolId`, the defaults of the components, chat templates, document analysis policies, and assistant plugins all name collections now, and the ID of such a tool is the ID of its collection. The ID of a tool in a declared collection stands for its whole collection wherever it appears. A selection stored before the tool joined the collection selects the collection, and an organization which names one tool of a collection switches the whole collection off or raises its confidence. Of several levels set for a collection and its tools, the highest applies, and the minimum a tool declares itself does not count once it belongs to a collection. + +Three methods of the registry translate between both views: + +- `ToolRegistry.NormalizeSelection` turns a selection into the collections which run.

Refuse a wrong one rather than guessing what it meant: a placeholder such as `0` is not a page, and reading it as "no page" does something the model did not ask for. The model reads the refusal and tries again, so the message has to name the argument and the value that arrived, say what would be valid, and, for an optional argument, that leaving it out is always possible. `ToolArgumentReader` reads strings, positive integers, and values out of a fixed choice, alone or as a list, and words the refusals so; `WebSearchTool` shows how a tool uses it. @@ -134,12 +165,23 @@ Every successfully retrieved page with readable content is also returned as a st `read_web_page.freeAddressChoice` decides whether the model may read addresses it chose itself. `OFF`, the default, tells the model to read only URLs which appear word for word in the conversation: in the system prompt, in a user message with the documents and data source content it carries, or in a tool result. When none fits and no other tool can find one, the model asks the user. `ON` lets it choose addresses as well. The values are the members of `FreeAddressChoice`, offered through `ToolSettingsOptionSources.FREE_ADDRESS_CHOICE`, and the setting follows the usual precedence of tool settings: a locked organization value, then the user's saved value, then an organization default. -Both values are instructions to the model, not a technical check of where a URL came from. Such a check would have to know every way an address reaches the model: attachments are read from disk only when a message is sent, pages link relatively, and servers redirect, so a URL the model reads correctly may still match no spelling in the conversation. A technical check is left for a change of its own. What the application enforces is the same either way: the network target restrictions of `WebPageRetrievalService` and the prompt-injection filter. +`OFF` is enforced as well: `read_web_page` refuses an address which was not given to the model, see `ChatThread.IsWebAddressGivenToTheModel`. Given means that the address stands in the system prompt the last request was sent with, in a user message or a document attached to it, or in the result of a tool. What the model wrote itself never counts, its earlier answers included. Each source is collected where its text exists in full: the system prompt in `PrepareSystemPrompt`, the attached documents in `ContentText.PrepareTextContentForAI`, since they are read from disk only when a message is sent, and the tool results in `ToolExecutor`. Relative links need no care of their own, because the page extraction makes every link absolute before the model sees it. Two addresses count as the same when they ask the server for the same, see `WebAddresses.CreateRequestKey`: scheme and host regardless of case, path and query exactly, the fragment not at all. A redirect may go anywhere, since the server rather than the model chose it. + +An address in a tool result counts only when it is no echo of the call: one which stands in the arguments, even as a part of one, is left out, because Semantic Search returns its query, and the model could otherwise turn any address it makes up into one a tool returned. The tool results are kept for the session only, like the results themselves, so after a restart a chat knows fewer addresses, never more. A refusal never repeats the address, for the same reason. On top of this, the network target restrictions of `WebPageRetrievalService` and the prompt-injection filter apply with both values. Links in a tool result count as given with both values, a link on a page read before included. Searching and then reading what was found is what these tools are for, and `search_confluence` opens its hits that way. Before this setting existed, the instructions forbade following a link which only retrieved content mentioned; that rule was dropped on purpose. Following a link word for word cannot carry anything out of the conversation. Putting parts of the conversation into an address could, so the instructions forbid that with both values. The instructions depend on the setting, so `read_web_page` words them per request through `ResolveSystemPromptInstructionsAsync`. Its registered instructions are those of `OFF`, and the token count below the message field counts with them. With `ON`, a request carries a shorter instruction, and the count comes out a few tokens high. +### After Reading Mails + +`read_web_page` contacts addresses the model chooses, so a chat which read from a mailbox would keep it from running. It keeps to the outbound data restriction itself instead, see `ReadWebPageTool.IsAllowedByOutboundDataRestriction`: + +- `ONLY_LINKS_FROM_CHAT` allows the addresses given to the model, by the same rule as the free address choice, and the pages of the Confluence wiki configured for `search_confluence`. +- `ONLY_CONFIGURED_SERVICES` allows the pages of that wiki only.

An address given to the model may be redirected anywhere, since whatever the redirect carries came from the server.

The classic RAG process, `AISrcSelWithRetCtxVal`, searches them with every message instead, using the message as the query. One place decides which of the two runs, `ToolRegistry.GetEffectiveRetrievalModeAsync`. Semantic search is the default, and the user can choose the other way per chat through `DataSourceOptions.RetrievalMode`.
