Subject: [PATCH 01/33] feat: add country selection for AT/DE support

Add a `set-country <code>` command (at/de) that switches the API
endpoint between marktguru.at and marktguru.de. The login command
also uses the configured country so the extracted API key matches
the correct domain. Defaults to "at" for backward compatibility.

Subject: [PATCH 21/33] chore: lint with eslint and prettier, drop oxlint (#12)

Same setup as cdk-ec2-key-pair: typescript-eslint with type-checked and
stylistic rules, prettier enforced through eslint, and a Makefile that CI
calls. The config is ported to ESM, since this package is type: module.

Rule exceptions: quoted object properties keep their case (HTTP headers),
variables may be PascalCase (class from a dynamic import), and
prefer-nullish-coalescing ignores strings and numbers, where `||` is meant
to catch empty values too.

Fixes the type-aware findings: JSON.parse and response.json() are typed
instead of any, commander action handlers get typed parameters, the two
floating search promises are awaited via parseAsync, and fetchFirstOk
rethrows an Error rather than an unknown.

 ## Query Syntax (Observed)
+
 The API appears to accept a Lucene/Elasticsearch-style query string, not SQL.
 
 Supported:
+
 - `OR` for boolean OR
 - `*` wildcard (e.g., `kell*`)

 - `AND`, `NOT`, `~`, `^`
 
 ## Notes on `login`
+
 - Uses HTTP requests (no browser automation).
 - Scans entry HTML and boot scripts for embedded API keys and validates them.
 - May break if the website changes.

Subject: [PATCH 22/33] fix: keep --version in sync with the released version
 (#13)

The version passed to commander was hardcoded, so the CLI would keep reporting 0.1.0 after any release. Annotate the line with x-release-please-version and list src/cli.ts as an extra-file, so release-please bumps it along with package.json.

Subject: [PATCH 23/33] chore: cache npm downloads in CI and stop automerging
 majors (#14)

The test workflow relied on setup-node's cache, which never matched the
cache directory make install writes to (--cache .npm), so every run
started cold. Cache .npm explicitly, like cdk-ec2-key-pair does.

Also adds the concurrency group and bash shell defaults from the same
reference setup, and stops Renovate from automerging major updates.

+# AGENTS.md
+
+Guidance for coding agents working in this repository.
+
+## Commands
+
+The Make targets are exactly what CI runs (`.github/workflows/test.yml`), so
+prefer them:
+
+```bash
+make install          # npm clean-install --prefer-offline --cache .npm
+make eslint           # lint
+make format           # prettier --write .
+make test             # build, then run the test suite
+make validate-package # npm pack and assert the tarball contents
+```
+
+Running the CLI locally — the `--` separator is required to pass flags through
+npm:
+
+```bash
+npm run dev -- --help    # tsx, straight from TypeScript
+npm start -- --help      # from dist/, needs a build first
+```
+
+Single test file / single test case:
+
+```bash
+npm run build && node --test tests/query.test.js
+npm run build && node --test --test-name-pattern "<name>" tests/query.test.js
+```
+
+## Architecture
+
+ESM throughout (`"type": "module"`), TypeScript compiled to `dist/` with
+`NodeNext` resolution — relative imports must carry the `.js` extension.
+
+`src/cli.ts` is the Commander entry point and the `bin` target. It delegates to
+a command module in `src/commands/`, which calls `ensureApiKey` (reads
+`src/config.ts`, falls through to `src/auth.ts` when no key is stored), then
+`search()` in `src/api.ts`, then renders through `formatResultsText` or
+`simplifyOffer` in `src/commands/search.ts`. `src/query.ts` is pure and
+I/O-free, which is why it carries most of the test coverage.
+
+Results go to stdout; `--explain` and every warning go to stderr, so `--json`
+output stays pipeable.
+
+## Constraints
+
+These are the things that are easy to break without noticing.
+
+- **Tests run against `dist/`.** `tests/*.test.js` import `../dist/*.js`, so a
+  stale build silently tests old code. `npm test` runs `npm run build` first for
+  exactly this reason — never invoke bare `node --test`.
+- **release-please owns the version.** `src/cli.ts` carries
+  `.version('0.1.0') // x-release-please-version`; the trailing comment is
+  load-bearing and matches `extra-files` in `release-please-config.json`. Never
+  hand-edit the version in `package.json`, `src/cli.ts`, or
+  `.release-please-manifest.json`.
+- **Country validation is a security guard.** The country code is interpolated
+  into a hostname, so `getApiBase()` and `extractApiKey()` hard-validate against
+  `VALID_COUNTRIES` before building a URL. Do not relax this. Only `at` and `de`
+  exist.
+- **API keys are country-scoped.** `set-country` deliberately clears `apiKey`
+  when the country actually changes, and `search` auto-logs-in using the
+  configured country.
+- **`login` is scraping, not an account login.** It fetches the public site,
+  regex-scans the HTML and boot scripts for an embedded key, and brute-force
+  validates candidates against the live search endpoint. It makes real network
+  requests, cannot be unit-tested offline, and breaks whenever Marktguru ships a
+  new frontend bundle.
+- **The key is stored in plaintext** at `~/.marktguru/config.json`. The `config`
+  and `login` output truncates it — preserve that.
+- **`--retailer` filters client-side** on `advertisers[].name`, which is why
+  `runSearch` over-fetches 100 results and rewrites `totalResults` to the
+  post-filter count.
+- **Two different default limits:** 10 in `src/commands/search.ts`, 20 in the
+  `search()` fallback in `src/api.ts`.
+- **ESLint covers only `src/` TypeScript** via the `tsconfig-lint.json` project.
+  The JS tests are not linted, and a new `.ts` file outside `src/` makes
+  type-aware linting fail.
+- **Exact dependency versions only** — no `^` or `~`.
+- **`make validate-package` asserts a hardcoded file list.** Extend it when a
+  new shipped entrypoint is added. It currently omits `dist/commands/*.js` even
+  though those ship.
+
+## Release flow
+
+PRs are squash-merged, so the **PR title must be a Conventional Commit** — it
+becomes the changelog entry, and `pr-conventional-title.yml` enforces it.
+Renovate forces `chore:` for dependency bumps and does not automerge majors.
+release-please opens a release PR on every push to `main`; a Monday 09:00 UTC
+cron automerges the single PR labeled `autorelease: pending`, so releases go out
+weekly rather than per merge. The resulting `v*` tag triggers
+`npm publish --provenance` via npm trusted publishing (no `NPM_TOKEN`).
+
+## Keep in sync
+
+`SKILL.md` documents *using* the CLI for agents that consume it; `README.md`
+documents the same surface for humans. Changing a command or flag means updating
+both.

Subject: [PATCH 28/33] chore: drop header-generator dependency (#18)

* chore: drop header-generator dependency

The marktguru site serves identical responses with static headers, so generated browser fingerprints add nothing. Removing it also drops the deprecated lodash.isequal (via ow@0.28) that warned on install.

Release-As: 1.0.1

* test: add live end-to-end tests for login and search

Runs the built CLI against marktguru.at and marktguru.de with an isolated HOME, so search has to auto-login by scraping. Catches the scraper breaking when Marktguru ships a new frontend.
