git-env-branchesgit-env-branchesA command line that shows, for a list of feature branches, which environment branches such as DEV, ACC and master each one has been merged into.independent, general
Shows which feature branches reached which environment branch
A team that does not keep one long-lived branch per environment has no environment branches for it to compare feature branches against. What it reports is the merge state of branches in Git, so it says nothing about whether a merged change has been built or deployed to the environment.

CAP Developers - Call to Action to mitigate and Apply Solution provided in SAP Note 3747787CAP Developers - Call to Action to mitigate and Apply Solution provided in SAP Note 3747787Four malicious npm package versions published on 29 April 2026 that exfiltrate credentials and propagate into adjacent repositories, and what a CAP developer should check. A security advisory rather than a technique, and dated precisely for that reason.Yogananda, published 2026-05-01
CAP: The Road Ahead - Simplicity in an AI EraCAP: The Road Ahead - Simplicity in an AI EraDevtoberfest 2026 session CAP10, from the head of SAP's Cloud Application Programming Model: forty minutes of live building rather than slides, on the argument that the cheapest code in an AI project is code nobody has to generate. Claude Code builds an invoice-matching workspace from cds init onwards, and each step is one the framework answers rather than the agent: a 42-line domain model that @sap/cds serves as OData and Fiori elements with a status flow, data privacy and change-tracking annotations that produce audit log entries in the console and would reach the SAP Audit Log service once deployed, an imported S/4HANA supplier data product, and semantic matching from a local embedding model after @cap-js/ai is added. The last three steps are annotations: @mcp beside @odata turns the service into an MCP server that a second Claude session queries through @cap-js/mcp, an agent annotation adds the A2A protocol with an agent card and an audit log entry for the agent task, and a skill file gives the agent the matching policy.SAP Developers, published 2026-09-25

Transactional processing of asynchronous and periodic CAP events
If you need sub-second fan-out to external consumers this is the wrong layer — reach for [Event Mesh](artifact:btp-event-mesh) or Kafka. Without [Redis](external:redis), periodic processing still works but instant dispatch degrades to polling.

It walks through OAuth 2.0 client-credentials authentication and the generated client's Jobs API, listing, creating and reading jobs with their cron schedules, and lists what the service's error statuses (400, 401, 404, 409, 429, 503) mean to a caller.

Building a SaaS Multitenant Application Using SAP CAP Framework — Without a DatabaseBuilding a SaaS Multitenant Application Using SAP CAP Framework — Without a DatabaseMultitenancy with the database taken out, which is a useful way to see what is left: the approuter and its tenant host pattern, the XSUAA instance in shared tenant mode, and the SaaS Registry binding that makes a subscription happen. Everything here is subscription lifecycle and routing, so the parts that are usually entangled with HDI container provisioning are visible on their own.DebashishDas, published 2026-05-06
Custom Business Logic Extensibility in CAP (CDS-Oyster)Custom Business Logic Extensibility in CAP (CDS-Oyster)A Devtoberfest 2026 session walking @sap/cds-oyster — at version 0.55, with 1.0 stated for Q4 — end to end on a multitenant xtravels, from the application developer's side and the extension developer's side. The application developer adds a submit-for-review action to the status flow and opens exactly one surface for custom code: a separate extension service marked as extensible code, holding a no-op validate action and two read-only helper entities, which the host application calls before the status change; nothing else is extensible, because the annotation defaults to false. The extension developer works in a project whose base model came from cds pull, with test data, a server.js and types from @cap-js/cds-typer added so the UI and code completion work, debugs the handler locally and pushes it as an @sap/cds-mtxs extension, after which the next request rejects a travel over the policy limit without a restart — the code having been stored as an annotation in the tenant's model and run in a Rust WebAssembly sandbox with no database connection, whose queries go back to the CAP runtime as CQL strings, which is tenant extensibility extended from fields to logic.published 2026-10-09

When user-dependent responses are cached without user-aware or explicit operation keys, or translated responses share keys across locales. These cases require key isolation; locale-aware keys are off by default.
CAP in the age of AI #5 - agents wrap-upCAP in the age of AI #5 - agents wrap-upThe agents topic closed out on what sits around the agent rather than inside it, now that the documentation has moved into capire. The chat preview's session is persisted in the database rather than kept in memory, traces go out through @cap-js/telemetry to a self-hosted MLflow under the OpenTelemetry conventions for generative AI, and the panel is explicit that @agent reuses the MCP adapter's code programmatically without serving an MCP endpoint. It ends in the xtravels sample, where a travel agent delegates to a hotel-service sub-agent and reaches a separately started flight service over MCP through the service binding CAP resolves anyway. Earlier in the hour the same agent answers from a model running on the presenter's laptop, reached as an OpenAI-compatible endpoint.published 2026-10-02
