feat(cli): replace Docker-based get-sync-token with native Obsidian API call

[aliasunder]

Summary

• Replace the Docker-based get-sync-token with a direct fetch to api.obsidian.md/user/signin — the same endpoint the obsidian-headless CLI uses. Removes the 2 GB Docker Desktop prerequisite from token capture.
• The new flow prompts for email, password, and MFA code (when 2FA is enabled) via clack prompts, with a 30s timeout, spinner feedback, and per-failure-mode error messages.
• init --mode remote now always offers "Generate the token now?" regardless of Docker status — the token capture no longer needs Docker at all.
• Remove runObsidianLogin from DockerRunner, buildObsidianLoginArgs, and all test stubs — dead code after this change.
• Update CLI README, deploy guides (Railway, Render, remote), and the get-sync-token program description.

Design

The API contract was verified from obsidian-headless v0.0.14 source:

• POST https://api.obsidian.md/user/signin with { email, password, mfa } and Origin: https://obsidian.md header
• Success: { token, name, email } — no error field
• MFA required: 200 with { error: "...2FA code..." } — prompt and retry
• Wrong MFA: { error: "...2FA code is incorrect..." } — no retry
• Wrong password: { error: "Invalid email or password" }
• Server error: HTTP non-200

The MFA detection mirrors the exact logic from the ob CLI's login command.

fetchFn: typeof fetch is injected via DI (same pattern as init.ts's existing fetchFn), making the API call fully testable without mocking globals.

Test plan

• 15 unit tests for captureObsidianToken and runGetSyncToken — success, MFA flow, wrong MFA, wrong password, HTTP 500, HTTP 429, network error, timeout, non-JSON response, missing token field, --dir write, --dir missing .env
• 10 init tests updated — confirm always offered, auto-capture uses mock fetch, fallback uses mock fetch error
• 3 buildObsidianLoginArgs tests removed (dead code)
• Full suite: 3,063 tests pass, zero lint errors, clean build
• Manual: npx vault-cortex@latest get-sync-token with no Docker installed (beta publish)

🤖 Generated with Claude Code

Summary by CodeRabbit

  • Remote initialization offers automatic token capture regardless of Docker availability.

• Documentation

  • Deployment guides now recommend Node.js and npx for token setup, with Docker as an optional fallback.
  • CLI descriptions now reflect the direct account sign-in process.

Update AGENTS.md to describe the API-based token capture
Medium severity · tests · high confidence

AGENTS.md:1 — beyond the diff's line ranges, in code the changes touch or depend on.

AGENTS.md's structure tree description for cli/src/get-sync-token.ts reads 'Get-sync-token subcommand (Sync token auto-capture via volume mount)', which is now false: this PR replaces the Docker volume-mount capture with the native Obsidian API call. The conventions doc that agents consult to understand the codebase would mislead an editor of this module.

Failure scenario: An agent or contributor reading AGENTS.md to work on get-sync-token.ts is told capture happens via a volume mount and Docker, when the implementation now calls api.obsidian.md/user/signin directly — the description drifts from the code.

Suggested fix

Update the AGENTS.md entry to describe the new mechanism, e.g. 'Get-sync-token subcommand (Obsidian Sync token capture via the Obsidian signin API)'.

📝 Walkthrough

Walkthrough

The CLI now captures Obsidian Sync tokens through the Obsidian API. The flow supports credentials, MFA, request errors, token output, and .env updates. Remote initialization no longer requires Docker, and deployment documentation uses Node.js with Docker as an optional fallback.

Changes

Sync token API migration

Layer / File(s)	Summary
API sign-in and token capture cli/src/get-sync-token.ts, cli/src/docker.ts	The command posts credentials to the Obsidian signin API, supports MFA and timeout handling, and removes Docker login helpers.
Command and remote-init wiring cli/src/init.ts, cli/src/main.ts, cli/src/program.ts, cli/src/messages.ts	CLI wiring passes fetch to token capture and offers API authentication without a Docker availability check.
Authentication and initialization tests cli/src/__tests__/get-sync-token.test.ts, cli/src/__tests__/init.test.ts, cli/src/__tests__/command-stubs.ts	Tests cover successful sign-in, MFA, API failures, token validation, .env handling, remote prompts, and manual fallback.
CLI and deployment documentation AGENTS.md, cli/README.md, deploy/railway/README.md, deploy/remote/README.md, deploy/render/README.md	Documentation describes API-based token capture through Node.js and retains Docker as an optional fallback.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 36ee4

The PR retains redundant type assertions in tests that trigger lint warnings and conflict with repository style guidance; this is a small, localized cleanup with no stated runtime impact.

Handle timeouts specially in the MFA retry catch
Low severity · correctness · high confidence

cli/src/get-sync-token.ts:363 — beyond the diff's line ranges, in code the changes touch or depend on.

When an AbortSignal.timeout aborts the second (MFA-verification) request, the retry catch reports it as 'Could not sign in: The operation was aborted' with no remediation guidance. The initial-signin path has a dedicated TimeoutError branch, but the retry path is missing the same. The error string is also incorrect for a plain network drop during retry, which produces 'Could not sign in: fetch failed' inside MFA retry.

Failure scenario: User with 2FA enabled enters a correct code; the verify request times out after 30s. The output shows 'Could not sign in: The operation was aborted' with no timeout message; the user gets no indication they can simply retry the code.

Suggested fix

Route retryError through a function that maps a TimeoutError to the 'Request timed out — check your internet connection and try again.' message (matching the initial-signin branch).

The AGENTS.md entry was updated in the first commit of this PR — it already reads:

get-sync-token.ts                  # Get-sync-token subcommand (Sync token capture via Obsidian API)

The rootfs/usr/local/bin/get-sync-token entry (line 59) is a separate file — the shell script inside the container for the manual docker exec flow, which is unchanged.

[aliasunder]

Re: MFA retry timeout handling — warnSigninError is a shared function called by both the initial signin and MFA retry catch blocks (line 151: warnSigninError(retryError, prompts, true)). It checks error.name === "TimeoutError" first, regardless of the isMfaRetry flag, so the MFA retry path already produces "Request timed out — check your internet connection and try again." The bot didn't trace through the shared function.

Read OBSIDIAN_AUTH_TOKEN presence from the kept .env on re-init
High severity · correctness · high confidence

cli/src/init.ts:1 — beyond the diff's line ranges, in code the changes touch or depend on.

When re-running init --mode remote over an existing deployment and declining 'Generate the token now?', the flow marks the deployment token-missing and suppresses the start offer even when the kept .env holds a valid OBSIDIAN_AUTH_TOKEN. The run reads PUBLIC_URL and PORT from the on-disk .env but derives obsidianTokenMissing and startStatus only from the captured value, so a user with a working token is told to fill one in and is never offered to start.

Failure scenario: A user re-runs npx vault-cortex@latest init --mode remote in a directory whose .env already carries a valid OBSIDIAN_AUTH_TOKEN, consents to re-running setup, and selects 'No' on 'Generate the token now?' (the token already exists; the kept .env is accepted by default). The connect message prints 'Fill in OBSIDIAN_AUTH_TOKEN in

/.env, then start the server' and the start offer is skipped even with the container runtime running — the user must run start --dir ... manually despite a valid configuration.

Suggested fix

Derive token-missing from the on-disk .env the same way PUBLIC_URL and PORT are read: compute `obsidianTokenMissing = captured === '' && !readEnvObsidianToken(envFilePath)` (a kept file with a token is not missing one) and base the startStatus gate on that combined state so an existing token allows the start offer.

Add a test for declined capture with an existing on-disk token
Medium severity · tests · high confidence

cli/src/__tests__/init.test.ts:1 — beyond the diff's line ranges, in code the changes touch or depend on.

The new runRemoteInit fallback branch — token capture declined while the on-disk .env already holds an OBSIDIAN_AUTH_TOKEN — has no test, even though that branch drives the start-offer gate and the obsidianTokenMissing flag. The kept-existing-.env test accepts capture (true), so the sole-token-source-from-disk path is never exercised.

Failure scenario: A regression in hasExistingToken (say, dropping the readEnvObsidianToken fallback) makes a re-init that declines capture suppress the start offer and print 'Fill in OBSIDIAN_AUTH_TOKEN in

/.env' even though the kept .env has a valid token — and no test fails, because no it() seeds a kept .env, declines capture, and asserts the start offer fires.

Suggested fix

Add an it() seeding a kept .env with OBSIDIAN_AUTH_TOKEN=persisted-tok, answering `false` to the 'Generate the token now?' prompt, and asserting the connect message does not contain 'Fill in OBSIDIAN_AUTH_TOKEN' and the 'Start the server now?' offer fires.

Add unit tests for readEnvObsidianToken edge cases
Medium severity · tests · high confidence

cli/src/scaffold.test.ts:1 — beyond the diff's line ranges, in code the changes touch or depend on.

readEnvObsidianToken is a new exported function shipped without any unit test, while every sibling env reader (readEnvPort, readEnvPublicUrl, readEnvVaultPath, patchEnvObsidianToken, detectMode) has one. Its edge cases are the subtle part: an empty OBSIDIAN_AUTH_TOKEN= line must return undefined and a commented # OBSIDIAN_AUTH_TOKEN=... line must not match — the exact distinction that differs from detectMode's empty-value-matches behavior.

Failure scenario: A future edit makes the regex match the commented line (e.g. dropping the ^ anchor) or treats a whitespace-only value as a token; no test fails because no test exercises the reader, so a kept-.env re-init could stop offering the server start and mislabel the deployment as token-missing.

Suggested fix

Add tests in scaffold.test.ts covering: missing file → undefined, an active non-empty line → the token, an empty `OBSIDIAN_AUTH_TOKEN=` line → undefined, and a commented `# OBSIDIAN_AUTH_TOKEN=` line → undefined, asserting each exact value.

Match docker --env-file's last-wins precedence for OBSIDIAN_AUTH_TOKEN
Medium severity · correctness · high confidence

cli/src/scaffold.ts:1 — beyond the diff's line ranges, in code the changes touch or depend on.

readEnvObsidianToken reads the FIRST active OBSIDIAN_AUTH_TOKEN line while docker --env-file treats the LAST duplicate as the effective value, and patchEnvObsidianToken replaces only the first active line. On a .env with duplicate token lines, get-sync-token --dir patches the line the container ignores, and a re-init that declines capture can regenerate the file carrying the stale first value.

Failure scenario: A user's .env has OBSIDIAN_AUTH_TOKEN=old followed by OBSIDIAN_AUTH_TOKEN=newer (a hand-edit appended a line). docker --env-file reads newer, so the container authenticates with newer; running npx vault-cortex@latest get-sync-token --dir ./vault-cortex replaces only the first line, so the container keeps authenticating with the old value the user intended to rotate — the update reports success but has no effect.

Suggested fix

Mirror the last-wins convention this module already uses elsewhere: in readEnvObsidianToken, collect all active lines with `matchAll(/^OBSIDIAN_AUTH_TOKEN=(.*)$/gm)` and return `matches.at(-1)?.[1].trim() || undefined`; in patchEnvObsidianToken, replace every active line (`/^OBSIDIAN_AUTH_TOKEN=.*$/gm`) so no stale duplicate survives.

Correct the misleading comment in the init always-offer test
Low severity · correctness · high confidence

cli/src/__tests__/init.test.ts:1 — beyond the diff's line ranges, in code the changes touch or depend on.

The new test comment in init.test.ts claims 'the Docker-not-installed warning fires too' when token generation is declined without Docker. With hasExistingToken=false the flow forces startStatus to 'not-started' and never calls offerDockerRun — the only emitter of buildDockerNotInstalledMessage — so no such warning can fire; the comment states behavior the code path cannot produce.

Failure scenario: An editor reads the comment, believes a declined token capture with no Docker emits the install guidance, and later restructures the flow to rely on that assumption; the actual behavior (no warning, no start offer when the token is blank) is the opposite of the documented claim.

Suggested fix

Rewrite the comment to state only what happens: 'Token generation is always offered (uses the API, not Docker); with a blank token (capture declined) the start offer is skipped regardless of Docker status.'

Invert Railway and Render token capture to lead with the npx CLI
Low severity · conventions · medium confidence

deploy/railway/README.md, deploy/render/README.md:1 — beyond the diff's line ranges, in code the changes touch or depend on.

The Railway and Render guides still present Docker Desktop as the required lead path to capture the token ('Install and open Docker Desktop… The login runs inside a throwaway container, so Docker has to be running'), with the native no-Docker npx command relegated to an aside — contradicting this PR's removal of that prerequisite. Because the diff content is not shown in full, this is verified against the prior-review quotes rather than the current file text.

Failure scenario: A user who has Node.js but not Docker follows the 'Getting your Obsidian Sync token' section top-to-bottom: step 2 tells them to install Docker Desktop (~2 GB) before they reach the final 'Already have Node.js?' line that says no Docker is needed. The section's recommended method is the hardest available path and the instructions contradict each other for that reader.

Suggested fix

Invert the order: make `npx vault-cortex@latest get-sync-token` the main steps (terminal + command + copy token) and move the `docker run --rm -it --entrypoint get-sync-token …` command into a 'No Node.js?' fallback branch. Apply the same restructure to both deploy/railway/README.md and deploy/render/README.md.

Consolidating umm-actually PR-level comments

Several PR-level findings duplicate inline threads already resolved with replies, and the remaining new findings are false positives. Addressing each:

Duplicates of resolved inline threads:

• "Add a test for declined capture with existing on-disk token" — test exists at line 770 (preserves existing token and offers start when capture is declined on re-init). Inline thread replied + resolved.
• "Add unit tests for readEnvObsidianToken edge cases" — 5 tests exist at scaffold.test.ts:481-521. Inline thread replied + resolved.
• "Match docker --env-file's last-wins precedence" — follows established scaffold.ts first-match convention (same as readEnvPort, readEnvVaultPath, readEnvPublicUrl). Inline thread replied + resolved.
• "Correct the misleading comment in the init always-offer test" — comment at line 580 already reads correctly. Inline thread replied + resolved.

New findings (false positives):

• "Read OBSIDIAN_AUTH_TOKEN presence from the kept .env on re-init" — the code already does this: readEnvObsidianToken(join(targetDir, ".env")) at line 456, combined via Boolean(capturedToken ?? existingEnvToken). The test at line 770 proves the start offer fires when capture is declined but the kept .env has a token.
• "Invert Railway and Render token capture to lead with npx CLI" — the guides already lead with npx (steps 2-3), Docker is in a collapsible "Don't have Node.js?" fallback. The bot noted it compared against prior-review quotes, not the current files.

Previously addressed:

• "Update AGENTS.md" — already updated in the first commit of the PR. Replied twice (once from a prior session, once from this monitoring session).
• "Handle timeouts in MFA retry" — warnSigninError handles TimeoutError for both paths; test at line 197 proves it. Replied in a prior comment + inline thread.
