Why

Usage → Limits shows no OpenCode Go row for people on OpenCode 2. OpenCode 2 stores credentials in the credential table of opencode.db and no longer writes them to auth.json, so readOpenCodeGoUsageLimits found no key and reported unsupported.

What changed

When auth.json has no opencode-go key, the probe reads the active opencode-go API key row from opencode.db (read-only), then falls back to OPENCODE_API_KEY as before. A failed or missing database falls through quietly.

docs/user/usage.md now says Limits needs a Go API key.

Scope

Console OAuth logins have no Go API key. Supporting them needs the undocumented /console/api/go/status endpoint, which #14983 leaves as a maintainer decision, so it's not included here.

Refs #14983. Overlaps the docs-only #15664.

Verification

  • Typecheck and lint pass for the touched files.
  • Ran the probe against a temp opencode.db holding a Console OAuth row, an inactive Go key and an active Go key: it sent the active key and returned all three windows.
  • Added a matching test in OpenCodeProvider.test.ts. It couldn't run here: vp test fails on every it.effect file on clean main in this checkout (two vite-plus instances, Node 26 against ^24.13.1). CI should run it.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The production path now reads an OpenCode API credential from a local SQLite database and uses it for a networked usage request, changing sensitive credential-source and precedence behavior. An unresolved high-severity concern covers stale inactive credentials masking the environment fallback, so human review is warranted.

Not approved because:

📝 Walkthrough

Walkthrough

OpenCode Go usage lookup now reads eligible API credentials from OpenCode 2’s SQLite database. Inline auth content skips that lookup. Otherwise, a stored key takes precedence over auth.json, with the environment key as a fallback.

Changes

OpenCode Go credential lookup

Layer / File(s) Summary
Read and decode Go credentials
apps/server/src/provider/openCodeUsageLimits.ts
The helper opens opencode.db read-only and looks up the newest eligible opencode-go credential. It excludes inactive rows and prefers active rows over rows with a NULL active value. It uses only nonblank decoded keys and returns no stored key on database or decode errors.
Select and verify the Go credential
apps/server/src/provider/openCodeUsageLimits.ts, apps/server/src/provider/OpenCodeProvider.test.ts, docs/user/usage.md
Inline OPENCODE_AUTH_CONTENT skips the database lookup. Otherwise, a stored key takes precedence over auth.json, and OPENCODE_API_KEY remains the fallback. A test checks that an active database key is selected over competing credentials. The documentation states the local-run and Go API-key requirements and that Console-only sign-in is insufficient.

Merge Risk

Merge Risk: ⚪ Minimal · up to 49c29

This change lets OpenCode Go usage limits work with OpenCode 2 credentials stored in its database. No actionable merge-blocking risk was identified from the supplied review context.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 29cca

The change is limited to selecting a locally stored API key for the existing usage request. External-server isolation and the request destination remain unchanged. No security vulnerability was established, but database compatibility and protection of local credential storage remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated credential flow involves the server process, the selected local OpenCode credential store, and the Go account associated with the selected bearer token. No new destination or cross-service credential propagation was established; isolation between users sharing a deployment remains unverified.

Trust Boundaries and Controls

  • observed — The existing local-versus-external ownership boundary remains: disabled instances and nonempty external server URLs return before local credential access. The selected key is sent to https://opencode.ai/zen/go/v1/usage, not to the configured external server.
  • inferred — The database becomes an additional trusted authority for account selection. Redirecting that authority would require control over the credential database or the environment used to resolve its location; such control was not established for an untrusted remote caller.

Resilience and Maintainability Implications

  • observed — Read-only access and connection cleanup contain the lookup’s effect on OpenCode-owned credential state. Database failure does not trigger credential writes or migrations and instead permits the existing file and environment selection path.

- Around line 48-50: Update the API-auth decoding helper used by decodeApiAuth
to treat a blank or whitespace-only key as Option.none(), so the
OPENCODE_API_KEY fallback remains available; preserve valid nonblank keys.
- Line 45: Update the SQL query in the credential lookup to filter for active
credentials with `active = 1` before ordering by `time_updated` and limiting to
one result. This ensures an inactive `opencode-go` credential is not selected
when falling back to `OPENCODE_API_KEY`.
