## What I do I drive the `cds upgrade` CLI, interpret its findings, and walk the developer through each migration item with concrete fix instructions and links to the official CAP migration documentation on capire. ### What `cds upgrade` does `cds upgrade` is a deterministic command-line tool shipped with `@sap/cds-dk`. It is the foundation this skill works on top of. With `--fix` it: - Updates CDS-related dependencies in `package.json` to the target version - Runs `npm install` - Rebuilds the project with the new compiler - Sets compatibility flags that preserve previous behaviour where applicable Without flags it scans only — no changes to project sources or dependencies (the report files below are still written). With `--dry` nothing is written to disk at all — all output goes to stdout. In every mode it scans the project for breaking-change patterns and produces: - `findings.json` — structured per-rule matches with file positions, guidance, severity, compat flags, OpenRewrite recipes, and coverage signals - `UPGRADE_REPORT.md` — human-readable report grouping findings by scope - `UPGRADE_OVERVIEW.md` — short summary with scan numbers and quick wins ### What this skill adds The CLI's outputs are dense — many rules, many matches per rule, many of which may be false positives in any given codebase. This skill: - Filters false positives using per-rule `guidance` and generic FP rules - Reads source files to verify ambiguous matches - Searches for occurrences the
