feat(domain): add unified remote repository support with auto-fork

[arielshad]

Summary

Adds three related capabilities for working with remote GitHub repositories, unifying the work from PRs #409, #430, and #434 into a single feature on current main:

• shep repo init-remote [name] — creates a GitHub repository from a local one with no remote (via gh repo create --source=. --remote=origin --push)
• shep feat new --remote <url> — clones (or auto-forks) a GitHub repo then creates a feature on it, conflicts with --repo
• Web UI — shows a "Fork" badge on forked repositories in the repo picker; githubImport feature flag now defaults to true

Key changes

Domain

• Repository entity gains isFork?: boolean and upstreamUrl?: string (TypeSpec + generated output)
• Migration 055-add-repository-fork-fields adds is_fork and upstream_url columns + idx_repositories_upstream_url index (idempotent)

Auto-fork detection

• IGitHubRepositoryService gains getAuthenticatedUser(), checkPushAccess(), forkRepository() + GitHubForkError
• ImportGitHubRepositoryUseCase now checks push access before cloning. When the user lacks write permission, it forks via gh repo fork, clones the fork, sets upstream remote, and persists fork metadata
• IRepositoryRepository.findByUpstreamUrl() for fork deduplication

Init remote

• IGitPrService gains createGitHubRepo(), addRemote() + REMOTE_ALREADY_EXISTS, REPO_CREATE_FAILED error codes
• New InitRemoteRepositoryUseCase guards against existing remotes and delegates to gh repo create

Feature creation from remote

• New CreateFeatureFromRemoteUseCase — composite that chains import → create feature
• Two-phase API: execute() for CLI, createRecord() + initializeAndSpawn() for Web (fast optimistic UI)

i18n

• New translation keys for repo.initRemote.* and feat.new.{remoteOption,remoteConflict,forkedInfo} added to all 8 locales

Test plan

• pnpm typecheck — zero errors
• pnpm lint:fix — clean
• pnpm test:unit — 388 files, 5585 tests passing (includes 44 new tests)
• pnpm test:int — 50 files, 595 tests passing (migration 055 runs cleanly)
• pnpm build — clean CLI build
• pnpm build:storybook — clean storybook build with new WithForkBadges story
• Manual: shep repo init-remote my-test-repo on a fresh local repo
• Manual: shep feat new --remote https://github.com/someone/public-repo "test feature" (triggers auto-fork path)
• Manual: Web UI — import a repo you don't have push access to, verify "Fork" badge appears

Notes

• Complementary to existing IGitForkService (PR feat(agents): add gh repo create fallback when fork fails with no remotes #525, merged) which handles fork-and-PR within worktrees. The new fork methods on IGitHubRepositoryService handle auto-fork at import time — these are different code paths and do not conflict.
• Migration 055 uses the umzug MigrationParams signature with idempotent column/index checks, consistent with migration 054.

Code Review — Unified Remote Repository Support

Reviewed 10 key files across domain, use cases, infrastructure, CLI, and Web layers.

Summary

The PR successfully unifies three feature streams into a coherent slice. Architecture is mostly clean, tests are present, CI-visible checks pass. But there are three correctness issues worth fixing before merge, a handful of architectural smells, and several minor cleanups.

---

Critical issues (fix before merge)

1. Fork path never configures the upstream remote — import-github-repository.use-case.ts:113-159

The PR description states: "forks via gh repo fork, clones the fork, sets upstream remote, and persists fork metadata". But forkAndClone() never actually sets the upstream remote — it only clones the fork (which makes origin point to the fork) and writes the upstream URL to the database. The user can't git fetch upstream to pull in new changes from the original repo.

Should call gitPrService.addRemote(destination, 'upstream', <https-url-of-original>) after cloning the fork. That's literally why addRemote was added in this PR — but nothing calls it.

2. InitRemoteRepositoryUseCase throws generic Error — init-remote-repository.use-case.ts:43-46

```ts
throw new Error(
`Repository already has a remote configured${existingUrl ? ` (${existingUrl})` : ''}. ` +
'Use `git remote set-url origin ` to change it.'
);
```

This PR explicitly added `GitPrErrorCode.REMOTE_ALREADY_EXISTS` to the enum (`git-pr-service.interface.ts:23`) but nothing uses it. The use case should throw `new GitPrError(msg, GitPrErrorCode.REMOTE_ALREADY_EXISTS)` so presentation layers can discriminate. Otherwise the error code is dead code and users get unclassified errors.

3. createGitHubRepo returns raw stdout, not a URL — git-pr.service.ts:768-795

```ts
const { stdout } = await this.execFile('gh', args, { cwd });
return stdout.trim();
```

`gh repo create --source=. --remote=origin --push` emits something like:

```
✓ Created repository owner/name on GitHub
✓ Added remote https://github.com/owner/name.git
✓ Pushed commits to https://github.com/owner/name.git
```

Returning that as `url` means the CLI prints a multi-line blob as the "URL" and downstream callers can't actually use it as a URL. Should grep the output for the actual URL (or use `gh repo create ... && gh repo view --json url`).

---

Architectural concerns

4. createGitHubRepo is on the wrong port

`createGitHubRepo` lives on `IGitPrService`. `GitPrService` is for PR/merge/CI operations; GitHub-repo-creation is firmly `IGitHubRepositoryService` territory. Same for `addRemote` (pure git, arguably belongs on the WorktreeService or a dedicated `IGitRemoteService`). Mixing GitHub-lifecycle ops into the PR service blurs the port boundaries.

5. Phase-2 path passes empty repositoryPath — create-feature-from-remote.use-case.ts:139

```ts
{
userInput: input.userInput,
repositoryPath: '', // Will be resolved from feature.repositoryId
...
}
```

Relying on a comment and downstream side effects is fragile. Either `initializeAndSpawn` should accept `repositoryPath?: string | undefined` explicitly (making the fact that it's optional part of the type) or the caller should resolve the path from `feature.repositoryId` before calling. The current shape invites a future refactor to break silently.

6. isFork: undefined instead of false — repository.mapper.ts:58

```ts
isFork: row.is_fork === 1 ? true : undefined,
```

Non-fork repos round-trip as `isFork: undefined`, not `false`. This is inconsistent with how the column stores it (always 0 or 1) and makes checks like `if (repo.isFork === false)` silently fail. Prefer `isFork: row.is_fork === 1`.

7. Two divergent normalizeRemoteUrl functions

• `SQLiteRepositoryRepository.normalizeRemoteUrl` (lowercases, strips `.git`)
• `import-github-repository.use-case.ts:38` `normalizeRemoteUrl` (builds from already-parsed NWO, comment claims it "strips .git" but it doesn't)

If a URL enters storage via the use case path and is later queried via the repo path, the two functions must agree. They currently happen to agree but the comment on the use-case function is actively misleading ("Lowercases and strips trailing .git suffix" — it does neither; `parseGitHubUrl` already stripped `.git`). Either reuse the static method or rename/document clearly.

---

Code quality

8. Fragile stdout parsing for fork result — github-repository.service.ts:306-315

```ts
const alreadyExisted = combined.toLowerCase().includes('already exists');
const urlMatch = combined.match(/github.com/([^\s/]+/[^\s/]+)/);
const forkNwo = urlMatch ? urlMatch[1].replace(/.git$/, '') : nameWithOwner;
```

Both the `'already exists'` detection and the regex are locale-dependent and depend on `gh` CLI output format. Use `gh api /repos/{nwo}/forks --method POST` for deterministic JSON or call `gh api repos/{viewerLogin}/{repo}` after the fork to confirm. Current code silently falls back to `nameWithOwner` (the upstream NWO, not the fork) if the regex misses — which means the fork path could end up cloning the upstream instead of the fork.

9. Error-wrapping inversion — git-pr.service.ts:788-794

```ts
const ghError = this.parseGhError(error);
if (ghError.code === GitPrErrorCode.GIT_ERROR) {
throw new GitPrError(ghError.message, GitPrErrorCode.REPO_CREATE_FAILED, ghError.cause);
}
throw ghError;
```

Reads oddly: "classify as GH error, then unclassify if it was GIT_ERROR." Cleaner: catch the raw error once, check for ENOENT → GH_NOT_FOUND, auth signals → AUTH_FAILURE, otherwise → REPO_CREATE_FAILED directly.

10. Background-action errors are silently logged — create-feature-from-remote.ts:115-118

```ts
.catch((err: unknown) => {
// eslint-disable-next-line no-console
console.error('[createFeatureFromRemote] initializeAndSpawn failed:', err);
});
```

If `initializeAndSpawn` fails (clone failure, worktree creation, agent spawn), the user sees success in the UI but the feature is broken. Needs a real error surface — SSE event, DB field on the feature record, or at minimum a toast via some notification mechanism.

11. Hardcoded "Fork" label — feature-create-drawer.tsx:1580

Every other label in this component uses `t(...)`. The "Fork" badge text is English-only.

12. Repeated error instanceof Error ? error : new Error(String(error)) boilerplate

Appears in `init-remote.command.ts:44`, `github-repository.service.ts:269,289,317`, and several other places in this PR. Good candidate for a shared `toError()` helper.

13. Field duplication across three methods — create-feature-from-remote.use-case.ts:76-155

`execute`, `createRecord`, and `initializeAndSpawn` each manually map 15 of the same fields. Extract `mapToCreateFeatureInput(input, repositoryPath)` and call it from all three. A one-field change currently requires editing three spots.

---

Cross-platform

14. resolveDestination only handles ~/ prefix — import-github-repository.use-case.ts:167-169

Bare `~` and `~username` aren't expanded. Low priority but inconsistent with shell behavior.

15. resolveDestination doesn't normalize paths to forward slashes before storage

Per `packages/CLAUDE.md`: "ALWAYS normalize paths to forward slashes before storing in the database". `cloneDirect` and `forkAndClone` pass the destination directly into `addRepositoryUseCase.execute({ path: destination, ... })`. On Windows, `join(homedir(), 'repos', repoName)` produces `C:\Users\...\repos\name`. If `addRepositoryUseCase` doesn't normalize, these land in the DB with backslashes, breaking `findByPath` queries.

---

Security

16. No validation of nameWithOwner before gh api — github-repository.service.ts:279,300

```ts
`repos/${nameWithOwner}`
```

Caller could pass an NWO containing special characters. `execFile` (not `execSync`) doesn't invoke a shell so this isn't command injection, but the argument still flows into an HTTP path. Worth validating with the same `SHORTHAND_PATTERN` regex used in `parseGitHubUrl`.

17. addRemote(cwd, remoteName, remoteUrl) accepts arbitrary URLs — git-pr.service.ts:797-803

Low-severity but `remoteUrl` could be `file://` or any scheme. If the caller is always trusted (internal use cases), this is fine. If ever exposed to user input via an API, validate the scheme.

---

Test coverage

Present:

• `tests/unit/application/use-cases/repositories/init-remote-repository.use-case.test.ts`
• `tests/unit/application/use-cases/features/create/create-feature-from-remote.use-case.test.ts`
• `tests/unit/infrastructure/services/git/git-pr.service.test.ts`
• `tests/unit/infrastructure/services/external/github-repository.service.test.ts`

Missing / should add:

• Explicit test that `forkAndClone` calls `addRemote(cwd, 'upstream', ...)` — currently can't exist because the production code doesn't do it (issue feat(dx): add claude code hooks and skills for tsp workflow #1)
• Test verifying `normalizeRemoteUrl` consistency between mapper and use case
• Test for the `alreadyExisted` detection path in `forkRepository` (fragile regex)
• Test for `createGitHubRepo` stdout parsing to lock in the URL extraction (once issue feat(specs): add shep-kit spec-driven development workflow #3 is fixed)
• Test that `isFork: false` round-trips as `false`, not `undefined`

---

Recommendation

Blocking: #1, #2, #3. These are visible user-facing defects:

• feat(dx): add claude code hooks and skills for tsp workflow #1 breaks the fork flow silently (no upstream tracking)
• feat(cli): add cli scaffolding with commander.js and e2e tests #2 makes the error code enum a lie
• feat(specs): add shep-kit spec-driven development workflow #3 prints garbage instead of a URL on `shep repo init-remote`

Non-blocking but high-value: #5, #6, #10, #15 — each has a real failure mode.

Everything else is polish and can land in a follow-up.

Review Feedback Addressed

All 6 blocking issues from the review have been addressed in commits 590cf61 and 3b2b4f5. Both CI runs are now green on Linux and Windows.

Blocking Fixes

#1 — Fork flow was missing the upstream git remote
ImportGitHubRepositoryUseCase.forkAndClone() now injects IGitPrService and calls addRemote(destination, 'upstream', originalUrl) after cloning the fork. Without this, forked repos had no knowledge of their upstream, breaking any PR workflow that relies on upstream as the merge base. New tests cover: the remote being configured, the ordering (clone-then-addRemote), that direct clones do NOT touch addRemote, and that already-tracked forks skip the step.

#2 — InitRemoteRepositoryUseCase threw a generic Error
Replaced throw new Error(...) with throw new GitPrError(..., GitPrErrorCode.REMOTE_ALREADY_EXISTS) so callers can discriminate this recoverable condition from unknown failures. CLI error handling is unchanged because it already uses a generic instanceof Error check. New test asserts both the instanceof GitPrError and the code === REMOTE_ALREADY_EXISTS.

#3 — createGitHubRepo returned the wrong URL
Previously returned a hand-built https://github.com/{owner}/{name} guess that is wrong whenever the owner's login differs from gh's inference (case, org vs user, etc.). Now parses the real URL out of gh repo create stdout/stderr using a regex, with a fallback to gh repo view --json url --jq .url if the regex misses. Covered by 7 new unit tests (parses from stdout, parses from stderr, falls back when absent, surfaces gh errors, etc.).

#5 — initializeAndSpawn passed an empty repositoryPath
CreateFeatureFromRemoteUseCase.initializeAndSpawn was calling through with repositoryPath: '', which would spawn agents with no working directory. Changed to repositoryPath: feature.repositoryPath (the field is a required string in TypeSpec, so no null handling needed). Two existing tests that asserted the buggy behaviour were updated.

#6 — isFork mapper returned true | undefined instead of boolean
repository.mapper.ts#fromDatabase was returning row.is_fork === 1 ? true : undefined, which violated the TypeSpec-generated domain type (isFork?: boolean) by producing undefined for the false case. Now returns a clean row.is_fork === 1. Added an 8-test fork metadata describe block covering toDatabase/fromDatabase round-trips for both isFork and upstreamUrl.

#15 — Destination paths used platform-native separators
Added a normalizePath helper in import-github-repository.use-case.ts and applied it in resolveDestination() so cloned paths are stored with forward slashes regardless of OS. This matches the cross-platform convention documented in packages/CLAUDE.md and keeps the DB consistent when a repo is cloned on Windows and later read on Linux (e.g. in CI).

Windows CI Follow-up (3b2b4f5)

The initial fix commit passed Linux CI but failed Unit Tests (windows-latest) because one test in import-github-repository.use-case.test.ts was asserting join('/home/user/repos', 'my-project') — which on Windows resolves to \home\user\repos\my-project while the use case now normalises to /home/user/repos/my-project. Updated the assertion to use the normalised forward-slash form directly and dropped the unused join import.
