CAPVAL: A project is bornpublishedThis second CAPVAL post announces CAPVALcapvalReplaces the message a failed input validation annotation returns, and adds @validation.handler, which names a class that runs a check of the developer's own.independent, cap version 2.0, made compatible with CAP v8 after breaking changes there, with the fix shown as a custom
cds.middlewares.after error handler. It restates the plugin's @validation.message annotation alongside standard annotations such as @mandatory as the input validationInput validationRejecting bad input before it reaches the database. While this can be done manually inside a handler, there are solutions in place to derive type, range, enum and mandatory checks from the model definitions.SAP and community, unassessed mechanic the project builds on, and the release otherwise adds automated tests and release-automation GitHub Actions rather than new annotations.Input validationSat 24

Building Code-Based AI Agents on the BAIPpublishedA Devtoberfest 2026 session on writing the agent yourself rather than configuring one, which is the agent toolingAgent toolingBuilding an agent into your own application — the tools it may call, the state it keeps between turns, and the framework it runs in. Distinct from MCP servers, which expose an application to somebody else's agent, and from agent guidance, which is knowledge handed to a coding agent.SAP and community, unassessed edge: an agent is a model with tools, skills, memory and context around it, and the session reads the code of one built in CAP as a LangGraph state graph, with an agent node that calls the model, a tools node holding the MCP clients, and the edge between them looping until no tool is needed. It then shows the shorter route, a CDS service annotated for the agent protocol with its instructions and skills in an agent.md file. SAP AI CoreSAP AI CoreSAP's AI service on BTP: the runtime for AI assets, and through the Generative AI Hub inside it the access to foundation models, the orchestration service with its templating, masking, filtering and grounding modules, the Prompt Registry and Document Grounding.sap official, btp carries both, with the CAP service in front of it as middleware so the credentials never reach the browser, and that is what cap-agent-ui5-webuicap-agent-ui5-webuiGives a CAP agent a UI5 web interface out of the box, so an agent built in the service has somewhere to be talked to without a separate frontend project.independent, cap is demonstrated against: added as a dependency, it gives the annotated service a UI5 chat interface that can be deployed rather than only previewed. A Python multi-agent application on Cloud Foundry, where an orchestrator delegates to per-stack specialists so no single model sees every tool, closes the session.Agent tooling
SAP Meets the Agentic Web: CAP MCP - UI5 WebMCPpublishedA Devtoberfest 2026 session (CAP-42) that puts MCP and WebMCP side by side: MCP exposes a backend to an agent, WebMCP exposes the tools of a web page to whatever agent arrives at it, and only Chrome behind a flag and Cloudflare's Kite browser support the second one today. The CAP half starts with two agents scraping a Fiori elements app with PlaywrightPlaywrightA library that drives Chromium, Firefox and WebKit from code, written for end-to-end browser testing. For the things here it is the browser a tool starts itself, to get through an SAP login or to load a page headless and photograph it. and browser dev tools, then annotates the catalogue service with the MCP protocol through @cap-js/mcp@cap-js/mcpA CAP plugin that serves an @mcp-annotated service over MCP with three generated tools, describe, query and call_action, and writes its endpoint into the local agent's configuration in development.sap official, cap, after which the agent calls the generated describe tool instead of parsing pages. The UI5 half registers a search-authors tool on the browser's model context API inside the same app, with the cross-origin isolation header the API requires, and lists it through the WebMCP Chrome extension — the agent run against it ends on an exhausted Gemini key rather than a result.Serve your application over MCP

A bookshop gets an MCP endpoint beside its OData one from a single annotation, with the plugin writing the coding agent's configuration itself; in the xt-travels sample five services that know nothing about each other are served over MCP and an agent does the orchestration the hand-built UI and its value helps used to do. Hutzel then annotates a service as an agent so the ReAct loop and the choice of model move into the CAP service, and finally drops MCP for a skill that teaches the agent CQL instead, which is where the edges to Serve your application over MCPServe your application over MCPExposing selected application data and business operations to an AI agent through the Model Context Protocol.

secondsky/sap-skillstype properties, flavors revisedRead today in the two plugins that answer the CAP and the UI5 door, which the ABAP pass had not opened. The sap-cap-capire skill's frontmatter states that it covers Node.js and Java runtimes, so CAP's two flavors rest on the maintainer's sentence where the entry previously answered in both by the serves-another-door fallback, which is the same reading off an absence. The sapui5 skill's frontmatter names freestyle apps and Fiori elements apps in one clause, so freestyle is stated, and fiori-elements moves onto that sentence from the README line about which request activates sap-fiori-tools, which said what triggers a plugin rather than what it covers. Nothing read names UI5 Web Components, so that flavor stays unstated. Stating freestyle changes an answer: the entry answered no there while it stated one UI5 flavor and now answers yes, which a reader comparing that flavor's options will see. The ABAP pair is unchanged.Agent guidance
Werkbankprovides revisedWhat Werkbank adds for ABAP, CAP and UI5 is its catalog of development skills; the workspace itself is not specific to any of those stacks. Agent workspaces is narrowed back to BTP.Agent guidance

CAP in the age of AI #4 - more on agentspublishedAsking a human first, and telling the agent how to behave. Ordering a book through @cap-js/agents@cap-js/agentsSAP's own CDS plugin for building agents inside a CAP service, wired to audit logging and telemetry through peer dependencies rather than leaving observability to the author.sap official, cap happens without a question being asked; the human-in-the-loop annotation on the action turns the same request into an approve-or-reject step, which the episode follows down to the A2A status update that stores the task in an input-required state in the database — A2A itself being JSON-RPC 2.0 over HTTP with server-sent events for the stream. The rest is instructions on disk: an
agents.md in the service's own folder removes the question about how many copies to order, a skill under a skills folder is advertised by its description and read only when the agent decides the case applies, and either file makes the plugin build a deep agent instead of the plain one.Agent toolingCAP in the age of AI #6 - vector embeddingspublishedVector embeddings put to work in the incident managementcapire/incidents-appThe Incident Management reference application — the one SAP's own tutorial paths build, step by step, and the model cds add incidents-sample drops into a project.sap official, cap sample, answering whether this problem has been seen before.

@cap-js-community/business-metricsdescription revisedTelemetry curation for the CAP door. The README opens by calling it an extension library for @cap-js/telemetry and lists telemetry enabled in the application configuration as a prerequisite, and the graph held no edge between the two. Read against the README at commit eee01d0.Telemetry
@cap-js-community/commonprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. The edge rested on a link with no quoted sentence, and the README states both halves a reader needs: the apps in the app folder with a ui5.yaml come from the file system and everything else is proxied to the remote repository, with the configuration file in the approuter folder as the prerequisite.Caching
@cap-js/agentsdescription, provides, requires revisedHow the agent reaches a model was nowhere on the entry, while the Java module of the same plugin already carried the edge. capire's configuration table states that aicore is the default for the production and hybrid profiles and connects to SAP AI Core, with auto and mock as the development kinds, so the requirement is conditional and the condition names the alternatives.Agent tooling
@cap-js/aiprovides[llm-integration] revisedRe-read for the capability's impact assessment. The page still carries the claim, now in a longer sentence that also names the automatic service-binding resolution and the tenant-aware resource groups and deployments the coverage paragraph leans on, so the quote is the full sentence and the date is today's.LLM integration
@cap-js/telemetrydescription revisedTelemetry curation for the CAP door. The entry carried no paragraph and no property values, so the capability's comparison had nothing from the runtime's own answer on Node.js. Read against the README at commit e97874b, the 2.1.0 release, and capire's plugins page.Telemetry
@dxfrontier/cds-ts-dispatcherprovides[typescript-patterns] revisedThe edge said only that the package answers the capability. It now says what it contributes — decorators binding handlers, the three layers its documentation recommends, injection between them and the draft decorators — and states the four comparison facets the capability declares, each on the README sentence it rests on.TypeScript patterns
@dxfrontier/cds-ts-repositoryprovides[typescript-patterns] revisedThe edge carried no sentence. It now says which half of the arrangement the package answers, names the two ways its own documentation shows it being used, and states the persistence value of the capability's layers facet. draft_events is left unstated on purpose: BaseRepositoryDraft reads and writes the draft entity, which is not a place to handle the draft events, and stating the flag here would make the two look like the same fact.TypeScript patterns
@jerome-benoit/sap-ai-providerprovides[llm-integration], description revisedThe page opened with its index line alone, which left two facts a reader of this capability needs unsaid: that there are two routes into SAP AI Core and that only the model is replaced, not the SDK around it.LLM integration
@mi8y/cap-agents-memoryprovides revisedcapability:agent-tooling declared four comparison properties on 2026-10-15. Three are answered from the README's own opening and CAP notes, re-read the same day and unchanged, scoped to the node flavor: the package holds state between turns, it is written against LangGraph's Store API, and that state is rows in the CAP database under the request's tenant. The approval property is left out: the README says nothing about it.Agent tooling
@mi8y/cds-langgraph-persistenceprovides revisedThe entry stated the capability with nothing behind it while the README says exactly what the package holds. Read on 2026-10-15: checkpoints are short-term, thread-scoped state used to resume workflows, retain conversation history and support time travel, backed by CDS, requiring @sap/cds >= 10. capability:agent-tooling declared its comparison properties the same day, so the edge now answers three of them, scoped to the node flavor. The README's sentence about what to prefer for a new application has been reworded since 2026-09-21 — it now reads 'This package remains available for its existing CDS checkpointer implementation' — and the claim the page already carries is unchanged, so only the quote on the edge is new.Agent tooling
@neoimpulse/cap-js-bootstrapprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. The edge was a bare reference: the one capability this package answers carried no sentence and no source, which rule 10 does not allow. The package's own npm text names what it starts, cds watch per service and the router through cds bind --exec, and is quoted in its own language. Read through registry.npmjs.org because npmjs.com refuses the fetcher.Local development
@sang2x/captoolsprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. Its own command description states that it writes the resolved VCAP_SERVICES into default-env.json, which is the documented difference against cds bind, where only the place the credentials can be fetched from is stored on the machine. Stated as a fact about the file, with the consequence for a project named in when_not_to_use rather than as a judgement on the tool.Local development
@sanjay-sde/cap-js-log-controlprovides revisedTelemetry curation for the CAP door. The edge carried no sentence, and what the plugin does here is narrow: it lowers the verbosity of the telemetry logger and of the OpenTelemetry DiagLogger rather than producing or exporting a signal, so it states no signal and no destination. Read against the README at commit 587455e. Whether this entry belongs under telemetry or under logging is left open for review.Telemetry
@sap-ai-sdk/foundation-modelsprovides[llm-integration] revisedcapability:llm-integration declared model_access and response_streaming on 2026-10-15. The package's own chat-completion page, read the same day, states that its chat client streams over server-sent events, which is the fact that decides whether a chat surface can show an answer as it is written; the edge rested on the repository README alone before.LLM integration
@sap-ai-sdk/orchestrationprovides[llm-integration] revisedcapability:llm-integration declared model_access and response_streaming on 2026-10-15. The orchestration chat-completion page, read the same day, states that the model is the name property of the promptTemplating configuration and that the harmonised API behind it lets a different model be used without the client code changing, and that the client streams over server-sent events. Both facts decide something for a reader and neither was on the edge.LLM integration
@sap-ux/telemetryprovides revisedTelemetry curation for the CAP door. The entry stood among the options a reader compares for observing a running CAP service, and its own README places it elsewhere: a library SAP Fiori tools use to collect anonymous usage data. The sentence is recorded so the page states what it is; whether the edge, the cds-plugin type and the CAP door are right is left for review rather than changed here.Telemetry
@sap/cds-dkprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. The edge named the hybrid profile without naming cds bind, and the capability's new comparison columns need the sourced answers here: the parts of the local stack this starts, that it binds cloud services, and that only the location of the credentials is stored on the machine, which is the difference against a helper that writes them into a file.Generators
@sap/joule-studio-clidescription, provides, links revisedCurrent npm README for 2.0.4, published 2026-10-07, says "Installing
@sap/joule-studio-cli gives you two commands:" and lists joule and jl. SAP Help now installs this package for the new Studio workflow. The historical alpha package stays separately indexed; no unverified rename or lineage relationship is inferred.Agent tooling@saptarishi/cds-plugin-llmprovides revisedcapability:llm-integration declared the same two properties on 2026-10-15. This is the one option behind the CAP door whose README names providers on both sides of the SAP AI Core boundary, and the streaming value rests on the
stream method in the interface the README's own opening sentence lists. Both values are scoped to the node flavor, which is the only one this plugin states.LLM integrationcap-agent-ui5-webuidescription revisedThe README has grown well past what the page carried, and the entry stated the capability with no source at all. Read on 2026-10-15: it serves a freestyle SAPUI5 TypeScript chat client same-origin from the CDS server against the services carrying @agent, renders a picker for more than one agent where switching starts a new conversation, speaks nothing but A2A as @cap-js/agents serves it, pins that package to exactly 0.9.1 and says to expect breakage on upgrade, and ships a scripted LLM because the bundled mock can never call an action and leaves an @agent.hitl gate unreachable. The dependency on @cap-js/agents is what the plugin is written against, so it is a required edge rather than a sentence.Agent tooling
cap-handler-frameworkprovides[typescript-patterns] revisedThe edge carried no sentence while the artifact's own description carried the detail. It now says what the package contributes to this capability — method names as the binding, the generated index the service reads, the separate draft hooks and the shared context — and states handler_binding, dependency_injection and draft_events on the README sentences they rest on. The layers facet is left unstated: the feature list read today names no layer above the handlers.TypeScript patterns
cap-java/cds-aiprovides[llm-integration], description revisedThe 0.0.2-alpha coordinates are a fact about Maven Central and not a statement by the maintainer. capire's plugin list, read on 2026-10-15, says in SAP's own words that the Java version of the AI plugin is currently in alpha, which is the declaration a reader choosing between the two runtimes needs; it is quoted rather than paraphrased and the coordinates stay beside it.LLM integration
cap-llm-pluginprovides[llm-integration] revisedThe edge that names this entry's own home capability carried nothing: no sentence, no source, and no room for the comparison property the capability declared on 2026-10-15. The README at 1.5.1, re-read the same day, names the chat-completion method and the orchestration service's harmonised APIs, and both run through SAP AI Core, which is what the property states. response_streaming is left absent: the README's feature list says nothing about streaming, and absent is not no.LLM integration
cap-mcp-guardprovides revisedTelemetry curation for the CAP door. The edge said nothing about what the plugin contributes, and the README's own statement is narrow and conditional: one span per agent request, emitted into an OpenTelemetry SDK the application configures, with no exporter of its own. Read against the README at the master branch, last pushed 2026-08-14.Telemetry
cap-ui-telemetrydescription revisedTelemetry curation for the CAP door. This is the one option in the corpus answering the boundary the core states, that traces begin when a request arrives, and the entry did not say how it does it or that its records are logs rather than spans. Read against the README at commit 78e5d75.Telemetry
capire/skillsflavors, provides revisedThe edge carried one source and no quote. Re-read both eval files on 2026-10-15: the fixture path, the expected-output field, the named assertions and the stack marker are now quoted, and the capability's two comparison properties are answered from the same sentences.Agent guidance
cds-agentsdescription, provides revisedcapability:agent-tooling declared four comparison properties on 2026-10-15. Both brings values rest on their own sentence — CAPToolkit is the raw-tool layer and the production default, CAPAgent a ready-made ReAct agent for demos and small apps — and the protocol is the one its own executor names as a client, not a protocol it serves. The state and approval properties are left out: the README says nothing about either.Agent tooling
cds-plugin-handlersprovides[typescript-patterns] revisedThe edge carried no sentence. It now says how the plugin decides where a handler goes, which is by folder and file name rather than by a decorator, and states the handler_binding and layers values of the capability's comparison, each on the README sentence it rests on. dependency_injection and draft_events are left unstated: the README mentions neither.TypeScript patterns
cds-plugin-typescriptprovides[typescript-patterns] revisedThe edge carried no sentence. It now says what the plugin does at build time and that it says nothing about the arrangement of the code it compiles. Whether the edge belongs on typescript-patterns is an open editorial question recorded with the capability's review: capire now ships a cds build task for TypeScript in @cap-js/cds-typer, which puts this plugin beside the core's toolchain answer rather than beside the arrangement options. No facet values are stated, because the capability's four facets ask about the arrangement and the README answers none of them.TypeScript patterns
cds-routing-handlersprovides[typescript-patterns] revisedThe edge carried no sentence. It now says what the package binds and where it stops, and states the handler_binding and layers values of the capability's comparison on the README sentences they rest on. No lifecycle field was added: the README read today carries no statement by its maintainer about the package's end, and the predecessor sentence in the one-liner is another author's reading, already attributed as such.TypeScript patterns
cds2typeslifecycle, provides[typescript-patterns] revisedThe edge carried no sentence. It now says what the tool produces and that it says nothing about the arrangement of the code around it. Whether this edge belongs on typescript-patterns at all is an open editorial question recorded with the capability's review: generating types from a model is the typing concern, and this pass does not move the edge.TypeScript patterns
Cloud Identity Servicesprovides[capability:authentication] revisedThe only sentence about this service was its one-liner, so the capability page listed it beside the OAuth server with nothing to tell the two apart. SAP's trust and federation page states what the service is and what a tenant's own policies cover, and the default identity provider page states the corporate identity provider behind it, which is the property the BTP door now compares on.Authentication
com.sap.cds:cds-adapter-agentdescription, provides revisedcapability:agent-tooling declared four comparison properties on 2026-10-15. All four values are scoped to the java flavor, the only one this module states, and the last two are stated negatives rather than absences: capire states that conversation history sits in volatile memory and that @agent.hitl is not yet supported by CAP Java. The harness property is left out: neither page names an agent framework underneath the Java adapter.Agent tooling
com.sap.cds:cds-maven-pluginprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. The edge said the goal rebuilds and restarts and left out that whether it restarts or reloads depends on Spring Boot Devtools, and that on Windows it does not work without them, which is the difference a reader on this flavor meets first.Generators
com.sap.cds:cds-services-bomprovides revisedThe entry carried the Fiori draft lifecycle and not the annotations the same guide documents for Java. Capire's Serving SAP Fiori UIs guide names the Java configuration for the Fiori preview and one annotation the Java runtime reads itself, @cds.java.descendants.aggregate for a hierarchy view over aggregates. Without this edge the java flavor of capability:fiori-annotations had no provider of its own, although CAP Java serves the same annotated metadata. @http.CacheControl, which the same guide states is supported only on the Java runtime, is a response header rather than a rendering instruction and is left to capability:pagination-and-streaming.Configuration
DanKromp/skillOverflowprovides revisedThe entry's own prose said the collection covers UI5 and Fiori work and the edge cited only the total count. The UI5 pass needed to know what that coverage is, because this entry states no flavor and so answers in all of a door's flavors; the two rows name the skills the fallback rests on, which is what the capability's freestyle and web-components readings now cite.Agent guidance
dev-approuterprovides[capability:local-development] revisedcapability:local-development curation on 2026-10-15. The capability now compares its options by the part of the local stack each one starts, and this package's own description states the part. Nothing was entered for the two flags: the registry page carries no README, so whether it resolves a cloud binding itself is not stated anywhere read here.Local development
Joule Studioecosystem, artifact type, links revisedThe browser builder and managed runtime do not establish a separately subscribed and bound BTP service. Keep CAP and BTP as served views: the product overview names CAP development, and the current SAP Help tutorial requires "An SAP S/4HANA system configured with an SAP BTP destination." The architecture chapter is titled "Building AI Agents with SAP Joule Studio on SAP BTP" while distinguishing the SAP-managed runtime from Bring Your Own Agent in a customer subaccount. The CLI link is backed by the current npm README, which now ships both joule and jl; its atlas record is revised in the same batch. The positive basis for web-tool is SAP’s description of a visual browser-based builder with no local setup. It identifies the hosted development interface, including provisioned access; it does not classify the runtime as an unbound or customer-hosted service.Agent tooling
SAP Authorization and Trust Management serviceprovides[capability:authentication] revisedThe edge said only that the service answers authentication, so the page could not say which part of the concern it answers. SAP's architecture page states the three: the trust, the assertion it receives, and the token it signs. The two properties the BTP door now compares options on are stated from the same page: a token with no user present, and a corporate identity provider behind it.Authentication
SAP Power for Kiroprovides, description revisedThe entry said it is packaged as a Kiro power and not how it gets there or which Kiro it needs; the README read on 2026-10-15 states both.Agent guidance
secondsky/sap-skillslinks, flavors, requires, provides, description revisedThe same correction as description.what_it_solves, on the edge that carries this artifact's answer to the capability, so the two do not state the repository's evidence model differently. The rewording also removes the two em dashes the prose scan reported in this field.Agent guidance
ui5-cap-ai-featuresprovides[llm-integration], requires[sap-ai-sdk-orchestration] revisedThe edge read as an unconditional prerequisite while this entry's own when_not_to_use already said the package is an optional peer. The README states it in one sentence, quoted now: a frontend-only install does not need it and a backend project installs it explicitly, which is the distinction a reader deciding what to add to package.json needs. The edge to the HTML5 Application Repository is untouched; nothing was read for it in this pass.LLM integration
Werkbankecosystem revisedThe project homepage describes "A small, curated shelf of MCP servers and SAP development skills." Its own catalog spans ABAP (ARC-1 and ABAP Cloud), CAP (CAP Upgrade), and UI5 skills; the workspace is not specific to one stack. This intake follows the maintainer’s explicit request after the September source sweep passed it over for lacking a workspace capability; that concern now exists as Agent workspaces. The served views describe which users the project-owned install catalog addresses. Werkbank provides the workspace; each selected connector or skill supplies the stack-specific behavior. No SAP implementation capability is attributed to Werkbank itself.Agent guidance

Each specialist authenticates to its MCP server over Streamable HTTP with OAuth 2.1, and a shared module centralises the SAP AI CoreSAP AI CoreSAP's AI service on BTP: the runtime for AI assets, and through the Generative AI Hub inside it the access to foundation models, the orchestration service with its templating, masking, filtering and grounding modules, the Prompt Registry and Document Grounding.sap official, btp GenAI Hub model setup behind two credential layouts, one for local runs and one for the Cloud Foundry service binding, the LLM integrationLLM integrationCalling a language model from application code with the tenant, destination and credential handling already solved instead using an SDK call with a hand-rolled key.SAP and community, narrow by design side of the rewrite. Tool lists per agent drop from well over a hundred to a dozen or two, and routing failures become separable from tool-misuse failures by reading the trace.Serve your application over MCP

@sap/cdsprovides[service-integration] revisedThe option states the protocols it speaks for this concern, from its documentation's sentence (docs/concepts/design-roles-and-interfaces.md, P2). Both facets cite the published capire pages, and each value carries the sentence that names it. What it serves rests on cds.protocols, which names OData V4 and REST outright. What it consumes rests on the Remote Services page, which names OData and plain REST, and, for the OData versions, on the Consuming Services guide, the one capire page that enumerates them; that guide says it is outdated and kept for archival purposes, so the entry dates the reading. HCQL, which CAP-level Service Integration calls CAP's native protocol, is not in the atlas's protocol list and stays out until it is.Configuration

Multitenant SaaS Application using CAPparts, areas, edges revisedThe record states what its source draws around and between the parts (docs/concepts/reference-architectures.md §9.2): the provider and consumer subaccounts, the users and API clients, and the flow of subscription, data and authentication as the architecture page states it. On the checker's reading of the first draft: only the application is placed in the provider subaccount, since the page places nothing else there; the registration with the SaaS Provisioning service is the stated direction, not events the service raises; and API Management's policies are stated with no path, so no arrow.Multitenancy
SAP Document AIinterfaces revisedAn interface may be named and stays a field (docs/concepts/design-roles-and-interfaces.md §3.2, P7): the hub's catalogue states the two APIs' titles, versions and states, and SAP's Help pages name the channels and the workspace, so a design's arrow can say which surface it lands on and a reader has the page to open. The inbound channels read mail: SAP's Help page names mail as the only channel type, so the SharePoint folders the reference architecture mentions are its claim and not the maker's. No status is entered: the hub's state is a crawled claim reported beside the interface.Document extraction
SAP Document AIparts, areas, edges, roles, edges[client to docai] revisedThe ingestion page links the upload operation of document_information_extraction_api_v2 as the API-based integration, and the service now names that surface (docs/concepts/design-roles-and-interfaces.md §3.2, P7), so the arrow says which API it lands on and wears its protocol.Document extraction
