refactor: move onto the official Go SDK - #5
Conversation
Replace internal/api with github.com/spoo-me/spoo-go v0.3.0. The auth store implements spoo.TokenSource so the SDK owns refresh and rotation; the device flow keeps the loopback listener and delegates the protocol. Removes the keys commands (dashboard-only now), streams exports, maps update flags onto the tri-state PATCH, and surfaces claim tokens.

Make token rotation atomic.
rotate validates the presented refresh token, releases the mutex, and then calls issue, which re-acquires it. Two concurrent refresh requests that present the same valid token can both pass the check and both issue a new pair. The first caller then receives a pair that is already rotated out, which produces a spurious 401 in the CLI refresh path.
Keep the whole check-and-issue sequence under one lock.

Set Content-Type before WriteHeader.
w.WriteHeader(http.StatusCreated) commits the response headers. The Content-Type that writeJSON sets afterwards is discarded, so the 201 response carries a sniffed content type instead of application/json. Every other handler in this file returns the header correctly.
Set the header before the status code.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Guard demoLinks mutation with a mutex.
urlHandler writes l.Status into the shared demoLinks backing array from a request goroutine. urlsHandler, statsHandler, linkByAlias, linkByID, and the root redirect handler read the same elements from other request goroutines. net/http serves each request in its own goroutine, so this is an unsynchronized read-write pair on shared memory.
The TUI issues list and stats fetches concurrently with edits, so the race is reachable. Add a package-level sync.RWMutex and take it in the lookup helpers and in this write.

Preserve the rotated pair when keyring writes fail.
Save writes the rotated pair to credentials.json after keyring.Set fails. Load later prefers any existing keyring value. If the keyring contains the previous pair and recovers, the next request loads the rotated-dead pair and ends the session.
Track the active storage backend, or otherwise make Load select the newest persisted credentials. Add a recovery test with an old keyring pair and a newer fallback-file pair.

Add an explicit expiry-clear path to the TUI.

Post-merge review — this landed and shipped as v0.4.0 three minutes later, so everything below is already in users' hands via homebrew and scoop rather than sitting behind a gate. Framing the findings accordingly.
The port itself is good. It's the cleanest of the three SDK ports: the TokenSource adaptation is the right seam, the tri-state PATCH mapping is correct, and the branch caught and fixed an SDK regression mid-flight instead of shipping around it. Verified locally — go build ./... and go test ./... are both green, and every claim below was traced to the line that implements it.
Should-fix: server-controlled filename is an arbitrary file write
internal/cmd/export.go:84-88:
name := file.Filename
if output != "" {
name = output
}
out, err := os.Create(name)file.Filename comes from the response's Content-Disposition, and spoo-go's ContentDispositionFilename returns the raw header param — mime.ParseMediaType does not strip path separators. I checked all three forms against the stdlib:
attachment; filename="../../../evil.json" -> "../../../evil.json"
attachment; filename="/tmp/absolute-evil.json" -> "/tmp/absolute-evil.json"
attachment; filename*=utf-8''%2e%2e%2f%2e%2e%2fesc.json -> "../../esc.json"
All pass through verbatim, including the RFC 5987 percent-encoded form, and os.Create happily accepts absolute paths. So a response header is enough to truncate and overwrite any file the user can write.
Reachability. Production spoo.me never sends this — the aggregate filenames are constants in services/export/formatters.py and the per-link name comes from _link_filename. The trigger is a hostile or compromised API base: SPOO_API_URL pointing at a self-hosted instance, which is a documented path, and one that can be plain http:// (the mock runs on http://localhost:8080), where the header is also injectable on the wire.
This is pre-existing — the deleted internal/api/export.go did exactly the same thing, so the port didn't introduce it. It matters more now for a different reason: the port moved that logic into a public library, so the missing sanitization is no longer one CLI's problem, it's every spoo-go consumer's.
Fix belongs in both places:
spoo-go—ContentDispositionFilenameshould returnfilepath.Base(name)and reject empty,.,.., or anything still containing a separator. A library handing back a path-shaped string that consumers will pass toos.Createhas to defend that itself.spoo-cli—filepath.Baseon the server name anyway, and consider refusing to clobber an existing file without-oor a--force. Right nowspoo exporttwice in a row silently overwrites, because the aggregate filename is a constant.
Should-fix: the 451 affordance has no consumer
The bump commit (f815022) says it picks up "the 451 blocked predicate". Nothing uses it — grep for IsBlocked and ErrLinkBlocked across the tree returns zero hits outside the SDK.
humanize (internal/cmd/root.go:73-80) handles ErrSessionExpired and ErrLinkPasswordProtected and stops. So a blocked link falls through to the raw API message, which is exactly the case where CLI-owned wording earns its keep: "this link was taken down for safety" is a different conversation from "404". The predicate was added to the SDK for this; wire it up.
Should-fix: changed counts flags that serialize to nothing
internal/cmd/links.go:142-149:
if cmd.Flags().Changed("alias") {
params.Alias = alias
changed++
}UpdateURLParams.LongURL and .Alias are plain string with omitzero, not Opt[string]. So spoo links update <id> --alias "" increments changed, passes the "no changes" guard, sends {}, and reports success having done nothing.
Password, max-clicks and expires all correctly route the empty spelling through Opt[T]/Null[T](). These two are the only fields where an explicit empty value is silently swallowed, which makes the inconsistency easy to miss. Either reject the empty string for these two flags, or don't count them as a change.
Should-decide: the claim token goes to stderr on the piped path
internal/cmd/shorten.go:119 and :157 print the claim token to stderr even when stdout is piped. The reasoning for stderr is right — stdout stays exactly the short URLs — but the token is a bearer credential, and stderr is precisely what CI captures into build logs. On a public repo those logs are public, and anyone reading one can claim that link into their own account.
--json already carries claim_token for programmatic use, so gating the human notice on stderr being a terminal would keep the interactive value without writing a credential into logs that outlive the run. Your call on the trade-off — an interactive user redirecting stdout to a file would stop seeing it — but the CI-log path is the part worth deciding deliberately rather than inheriting.
Nits
export.go:43—if _, err := d.store.Load(); errors.Is(err, auth.ErrNotLoggedIn)discards every other error. A corrupt credentials file or a keyring failure falls through, the export runs anonymously, and the user gets a 401 instead of the actual problem.root.go:75-78—humanizereturnserrors.New(...), dropping the cause. That takes the SDK error'sRequestIDwith it, which is the one field that makes a support report actionable.fmt.Errorf("…: %w", err)keeps both.internal/auth/device.go— the callback handler doesn't read theerrorquery param, so a user who clicks Deny on the consent screen gets "authorization failed: callback carried no code" rather than being told they denied it.internal/auth/store.go:79— the SDK callsTokenSource.Token(ctx)before every request (client.gocredentials(), no caching), andTokendoes a fullkeyring.Get. Sequential bulk stdin shortening is one keyring read per line. The old client did the same thing per request, so this is not a regression — but the port restructured exactly this code, and a memo cache for the process lifetime is nearly free.
What's notably good
clientTag()validatesVersionagainst^[A-Za-z0-9._-]{1,16}$, which is the backend's own_CLIENT_TAG_REgroup-2 shape (shared/client_tag.py:16). A malformed or overlong version degrades to barecliinstead of sending a tag the parser drops wholesale. That's a detail almost nobody gets right.- The goreleaser ldflag was actually moved —
internal/api.Version→internal/cmd.Version. A stale-Xpath fails silently and would have made every released binary reportcli/dev, poisoning client attribution with no error anywhere. Worth a release-time assertion that the version isn'tdev, since nothing would catch the next drift either. - Catching the SDK's export regression inside the PR. spoo-go 0.3.0 had
ExportLinkon the aggregate route, which loses the alias in the download name and makes two links' exports collide on disk. The branch bumped to 0.4.0 and added a test pinning the per-link path. Fixing it upstream and pinning it downstream is the right response to a library bug, rather than working around it locally. - The tri-state PATCH mapping —
Changed()gating omission, sentinel spellings mapping toNull[T](), with the reasoning in a three-line comment. Correct against the API, which accepts0ornullto clearmax_clicks. resolveTargetannouncing the public-stats fallback on stderr, and distinguishing an explicit--domain(hard error) from the default domain (soft fallback). That's the distinction a user actually cares about.- The 869-line mock with device-token exchange, rotating refresh, bearer enforcement on owner endpoints, claim outcomes and password-gated public stats is an asset well beyond this PR — it makes the regression checklist runnable offline.
- Deleting 1906 lines while adding capability, and moving
inspect's HEAD probe out ofinternal/apibecause it probes the redirect edge rather than the API — right call, right reason.
Release posture
v0.4.0 is out, so the file-write finding is live in released binaries. It only bites users pointed at a non-spoo.me base, which is a small population, and the fix is a one-liner in each place — but it's the one I'd cut a v0.4.1 for rather than let ride to the next feature release, mostly because the SDK half affects consumers who have nothing to do with this CLI.

file.Filename is the raw Content-Disposition param and lands straight in os.Create. spoo-go's ContentDispositionFilename doesn't sanitize — verified against the stdlib:
attachment; filename="../../../evil.json" -> "../../../evil.json"
attachment; filename="/tmp/absolute-evil.json" -> "/tmp/absolute-evil.json"
attachment; filename*=utf-8''%2e%2e%2f%2e%2e%2fesc.json -> "../../esc.json"
All three pass through verbatim, and os.Create accepts absolute paths — so one response header truncates any file the user can write. Production never sends this (the filenames are constants in services/export/formatters.py); the trigger is a hostile or compromised SPOO_API_URL, which is a documented path and can be plain http://.
Pre-existing — the old internal/api/export.go did the same. What changed is that the port moved it into a public library, so it's now every spoo-go consumer's problem too. Fix ContentDispositionFilename to return filepath.Base and reject .., and filepath.Base defensively here as well.
Separately: this silently clobbers. The aggregate filename is a constant, so spoo export twice overwrites without asking.

The bump commit says it picks up "the 451 blocked predicate", but IsBlocked / ErrLinkBlocked have zero hits anywhere in the tree. humanize stops at session-expiry and password-protected, so a safety takedown surfaces the raw API message.
That's the case where CLI-owned wording matters most — "this link was taken down" is a different conversation from a 404. The predicate exists for exactly this.

UpdateURLParams.Alias (and .LongURL) are plain string with omitzero, not Opt[string]. So --alias "" increments changed, clears the "no changes" guard, serializes to {}, and the command reports success having done nothing.

The claim token prints to stderr even on the piped path. stderr is the right channel for keeping stdout clean, but the token is a bearer credential and stderr is exactly what CI captures into build logs — public ones on public repos, where anyone reading can claim the link into their own account.
--json already carries claim_token for programmatic use, so gating this notice on stderr being a terminal would keep the interactive value without writing a credential into logs that outlive the run. Trade-off is an interactive user redirecting stdout stops seeing it — your call, but worth deciding rather than inheriting.

This only branches on ErrNotLoggedIn and drops every other error. A corrupt credentials file or a keyring failure falls through, the export runs anonymously, and the user gets a 401 instead of the actual cause.
