# What is built

Each row says what is built and what is specified but not built yet.

| Feature | Status |
|---|---|
| Command help | Built: every command has `--help` with examples, `jadpo help [command]` explains one, and `jadpo help --json` describes them all. |
| Project path | Built: every command finds the project by walking up to `app.jadpo`, so a path is optional; run from outside the project, printed paths start with the project as typed. |
| Scaffold | Built: `jadpo new <name>` writes the fixed root on this `jadpo`'s release line with its project token, the `hello` domain (one route, its action, its policy line, its API record and a route test), `AGENTS.md`, `.gitignore` and `.gitattributes`, passing `check`, `fmt --check` and `test` as written, and refuses a folder that holds anything, with `--json`. The line an app declares is checked: `application { jadpo: "0.1" }`, with `toolchain.version_newer`, `toolchain.version_older` and `toolchain.version_invalid` ([The root](the-root.md)). |
| Which jadpo runs | Built in 0.1.0: every `jadpo` runs the release a project's line or `jadpo.lock` pin names, kept in the cache or fetched from GitHub's releases, its archive checked against its published SHA-256 and its GitHub artifact attestation (Sigstore's verifier, with the public-good trusted root carried in the binary) before it runs, and refuses with `toolchain.version_newer` or `toolchain.version_older` when it can't; `jadpo toolchain` lists, removes, pins and unpins, and `JADPO_TOOLCHAIN=local` runs everything with the `jadpo` started. The trusted root is the one this release was built with: no TUF refresh. |
| Formatter | Built: one member per line, one blank line between declarations, and `fmt --check` counts the files it read; it keeps `use` lines at the top, sorted, fixes imports inside a project, `--layout` makes promotion moves, and it writes each file's declarations before their use, the primary declaration last. |
| Error messages | Built: one error per mistake, in the field order [Error messages](error-messages.md) gives, `impact` only when it says something, edits on the next step where one exists, and help links to each error's page on the site. |
| JSON output | Built: every command takes `--json` and prints one envelope (`schemaVersion` 2) with project-relative paths and `data.root`, line and column beside byte offsets, and camelCase keys; `jadpo test --json` is described in [Testing](testing.md) and under `testReport` in `jadpo help --json`. |
| `build/` | Built: `jadpo check` writes `build/manifest.json` and the catalogues in `build/catalogue/`; `jadpo test` keeps its last run in `build/test/`. Not built yet: the reports, OpenAPI and the monitoring rules in `build/`. |
| Commands | Built: each command [The `jadpo` command](the-jadpo-command.md) and the topics after it describe, apart from those in their "Not built yet" notes. |
| Language server | Built: diagnostics; hover, with a query's SQL and a route's full path; go to definition, from a `use` line too; find references; completion; formatting as `jadpo fmt`; quick fixes from each error's edit, promotion among them; and the code actions under [Editor support](editor-support.md). Not built yet: rename, which waits for `jadpo rename`. |
| VS Code extension | Built: starts `jadpo lsp`, formats on save, highlights, a status item naming the `jadpo` running, "Open Generated File", and packaging and publishing on each release, switched off until the Marketplace and Open VSX are set up. |
| Agent tools | Partly built: the catalogues and the similar-helper check, a declinable error, are built; `migrate` is built; `impact`, `domain`, `rename` and `seed` are not built yet, nor are the agent skill and generated CI. |
| Suggestions | Built: `jadpo suggest` with its six signal kinds and taught signals, the catalogue, accepted findings, `ignore`, `found`, `share`, `suggestions { }` and the committed taught record, `share` against a fake of Jadpo HQ (HQ itself comes later). |
| Review and sign-off | Not built yet: `jadpo approval`, which comes with [Records and manifest](records-and-manifest.md). |
| Build-only errors | Built: `jadpo build` for the one deployable an app that declares none has and for declared deployables, with their `toolchain.target_*` errors; its `settings` line, and a Worker's `secrets: { required: [ ] }`, name every setting a deployable reads, its connections' included. |
