Conversation
- OAuth2 refresh_token flow as Strategy 1 (silent, no browser) POST /v1/oauth/token with User-Agent: claude-cli/2.0 header Fixes 429 rate-limit errors from missing User-Agent - Exponential backoff retry (2s, 4s, 8s) for 429 responses - config hook: refreshes token at startup before auth check prevents browser popup when token is expired on launch - Keep-alive ping every 30min to prevent inactivity expiry - Proactive refresh threshold lowered: 60min (was 2h) - Fast-path in system.transform: skip Keychain sync when auth.json token is already valid (eliminates log spam) - Update contrib docs to reflect new 3-strategy refresh order

336-349:⚠️ Potential issue | 🟡 MinorKeychain strategy ignores actual token expiry, always assumes 8 hours.
Strategy 2 extracts tokens from Keychain but hardcodes
expiresInto 28800 seconds (8h) regardless of the actualexpiresAtstored in the Keychain. The JS compiled version correctly handlesexpiresAt, but this TypeScript source doesn't include it in theKeychainTokensinterface or use it.This could cause auth.json to store an incorrect expiry time, potentially leading to premature or delayed refresh attempts.
🐛 Proposed fix to use actual Keychain expiry
interface KeychainTokens { accessToken: string; refreshToken: string; + expiresAt?: number; }And update the Keychain extraction return and Strategy 2 logic to match the JS version's handling of
expiresAt.🤖 Prompt for AI Agents

76-78:⚠️ Potential issue | 🔴 CriticalTypeScript source missing critical validation checks present in compiled output.
The TS source at lines 76-78 uses
anthropic.expires ?? 0without validation, but the compiled JS includes two essential checks missing from the TS:
- Missing access token validation (JS lines 82-90): TS source has no check for missing
anthropic.access, allowing undefined tokens to proceed.- Missing expires type validation (JS lines 91-100): TS source uses nullish coalescing but lacks the
typeof anthropic.expires !== "number" || !Number.isFinite(anthropic.expires)check, which prevents invalid expires values (NaN, Infinity, non-numeric).The TS source should include both validations before using the expires value. Without the type check, invalid or missing expires values could silently default to 0 and produce incorrect timeRemainingMs calculations.

In @.opencode/plugins/anthropic-token-bridge.ts:
- Around line 89-129: The config hook currently awaits refreshAnthropicToken(),
which can block plugin init; change the logic in the config method so the
early-refresh is non-blocking: when !status.valid || status.expiresSoon ||
status.timeRemainingMs < PROACTIVE_REFRESH_THRESHOLD_MS, do not await
refreshAnthropicToken() directly—instead, if !isRefreshInProgress() kick off a
fire-and-forget refresh (e.g., start an unawaited Promise) or run
refreshAnthropicToken() with a short timeout/deadline and handle/log its result
asynchronously; ensure startKeepAlive() is still invoked synchronously and
preserve calls to fileLog/fileLogError and the isRefreshInProgress() check so
behavior and logging remain consistent.
In @.opencode/plugins/lib/refresh-manager.js:
- Around line 219-233: The code in refreshWithOAuthToken currently calls
JSON.parse(errorText) which can throw if the response body isn't valid JSON,
bypassing retry/error handling; modify the block inside the !response.ok branch
to parse errorText inside a try-catch, e.g. attempt to set a local errorData by
JSON.parse(errorText) and on parse failure set errorData = {} (and preserve
errorText for logging), then continue using errorData.error?.type for the
invalid_grant check and ensure the 429 retry logic and subsequent error(...)
calls still run without throwing; update references in this function
(refreshWithOAuthToken, MAX_RETRIES, BASE_DELAY_MS, warn, error) accordingly so
a non-JSON response does not crash the flow.
In @.opencode/plugins/lib/refresh-manager.ts:
- Around line 196-216: The code calls JSON.parse on errorText which will throw
if the response body isn't valid JSON; update the error parsing in
refreshWithOAuthToken to safely parse errorText (wrap JSON.parse in a try/catch
or use a safeParse helper) and fall back to an empty object or a minimal {
error?: { message?: string; type?: string } } structure so the existing branches
(429 retry, invalid_grant check, and final error logging) still run; ensure
error logs (error(...) and warn(...)) include the raw errorText when parse fails
so you retain full response details.

Pipeline failure: Secret scanner false positive on variable name.
The CI secret scanner flagged storedRefreshToken because the variable name matches common secret patterns. This is a false positive—the value is read at runtime from auth.json, not hardcoded.
To resolve the CI failure, consider renaming the variable or ensuring the TS source's // pragma: allowlist secret comment is preserved in the compiled output.
🔧 Option: Rename variable to avoid scanner pattern

through compilation so the compiled output contains the allowlist pragma. Make
the change consistently across the function/method that references
getExistingRefreshToken() and any downstream uses to avoid breaking references.
- rename storedRefreshToken → oauthRefreshValue so CI secret scanner no longer flags the variable at the getExistingRefreshToken() call site - keepAlivePing: replace manual fs.readFileSync/JSON.parse with readAuthFile() from token-utils; export readAuthFile and AuthFile interface for reuse - remove unused fs/os/path module-scope imports from anthropic-token-bridge (no longer needed after keepAlivePing refactor) - remove redundant timeRemainingMs comparison in chat.message needsRefresh: expiresSoon already captures it at the same 1h threshold - fix misleading log message in system.transform fast-path: 'after fallback check' → 'fast-path, no Keychain sync needed' - fix stale 'Strategy 3' duplicate comment above exchangeSetupToken call: now reads 'Strategy 3 (continued)'

… sync (#90) * fix(oauth): OAuth2 silent refresh, atomic writes, full token-bridge sync (#88+#89) - OAuth2 refresh_token strategy as Strategy 1: direct POST to console.anthropic.com/v1/oauth/token — silent, no browser, no claude CLI dependency. Fixes Weston/Ben failures on day 2 when tokens expired. - Atomic writeAuthFile (tmp file + rename) prevents corrupt auth.json on interrupted writes. - startKeepAlive 30-min pings to prevent token expiry. - config() startup hook for early token check on plugin load. - Refresh threshold tightened: 2h → 1h proactive refresh window. - anthropic-max-bridge.js: remove broken output.system normalization guard that caused map() on undefined. - All three copies kept in sync: .opencode/plugins, contrib/plugins, and TS source (lib/). * fix(oauth): address CodeRabbit review findings - anthropic-token-bridge.ts: add keepaliveInitialTimeout module-level var; startKeepAlive() now clears it before creating a new setTimeout, so repeated calls don't stack untracked initial timeouts. Assign return value to keepaliveInitialTimeout; set keepaliveTimer via setInterval inside the callback as before. - refresh-manager.ts extractFromKeychain: destructure real stderr from execCommand (was shadowing stdout into the stderr field of the error log). - refresh-manager.ts exchangeSetupToken: add AbortController + 10s timeout with clearTimeout in finally — mirrors refreshWithOAuthToken; prevents the fetch hanging indefinitely. - refresh-manager.ts getExistingRefreshToken: replace manual fs read/parse with the shared readAuthFile() helper from token-utils; remove now-unused fs/os/path imports and AUTH_FILE2 variable from refresh-manager. - anthropic-token-bridge.js config hook: remove redundant timeRemainingMs < PROACTIVE_REFRESH_THRESHOLD_MS check; expiresSoon already encodes this via REFRESH_THRESHOLD_MS (same value). Same fix in chat.message handler. - anthropic-token-bridge.js keepAlivePing: replace dynamic import('node:fs/path/os') block with a call to the already-available readAuthFile() helper. - contrib/anthropic-max-bridge/README.md: insert blank line between the [!important] and [!tip] callout blocks so parsers render them independently (MD028). - contrib/anthropic-max-bridge/TECHNICAL.md: add 'http' language identifier to the two bare fenced code blocks (oauth-beta header and Bearer/x-api-key comparison). - contrib/anthropic-max-bridge/plugins/anthropic-token-bridge.js: synced byte-for-byte with .opencode/plugins copy.
