token-provider-exceptions

token-provider-exceptions is a cursor rule for Cursor from airweave-ai/airweave. It costs 0 tokens per session (1,070 once invoked), scanned A, original, MIT.

Rules for converting authentication failures from outside services into clear source-connection errors. They define different cases, such as expired credentials, revoked tokens, missing credentials, and deleted accounts.

In plain words
What is it for?
Use them when implementing or reviewing token providers, OAuth refresh handling, authentication failures, and source-connection error messages.
Why use it?
They preserve the original cause while giving the rest of the application an actionable error to handle.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

token-provider-exceptions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Token Provider Exceptions → Source Connection Actionability

Three exception layers

OAuth2 token endpoint / Auth provider API
        ↓ raises typed domain exceptions
OAuthRefreshServerError, OAuthRefreshTokenRevokedError, ...     (domains/oauth/exceptions.py)
AuthProviderAccountNotFoundError, AuthProviderAuthError, ...    (platform/auth_providers/exceptions.py)
        ↓ token providers catch + translate
TokenCredentialsInvalidError, TokenProviderAccountGoneError, ... (domains/sources/token_providers/exceptions.py)
        ↓ each carries:
        .provider_kind  ("oauth" | "auth_provider" | "static")
        .source_short_name
        .__cause__  (original exception)

Token provider exception hierarchy

TokenProviderError (SourceError)
├── TokenExpiredError                    — token is known-dead, cannot be refreshed (fast abort)
├── TokenCredentialsInvalidError         — token/refresh_token expired or revoked
├── TokenProviderAccountGoneError        — external record deleted (Composio/Pipedream)
│     .account_id
├── TokenProviderConfigError             — fundamental misconfiguration
├── TokenProviderMissingCredsError       — response missing required fields
│     .missing_fields
├── TokenProviderRateLimitError          — upstream rate-limiting
│     .retry_after
├── TokenProviderServerError             — 5xx / timeout / connection error from credential source
│     .status_code
└── TokenRefreshNotSupportedError        — static token / no refresh_token

TokenExpiredError is raised by get_token() when the provider knows the token is dead and refresh is impossible (e.g. the refresh_token itself is revoked). Callers should treat it as a permanent failure and surface NEEDS_REAUTH immediately without retrying.

How the SC domain makes this actionable

Connection status expansion

class SourceConnectionStatus(str, Enum):
    ACTIVE = "active"
    PENDING_AUTH = "pending_auth"
    SYNCING = "syncing"
    PENDING_SYNC = "pending_sync"
    NEEDS_REAUTH = "needs_reauth"   # ← credentials expired/revoked, user must re-authenticate
    ERROR = "error"                 # ← config/permanent errors
    INACTIVE = "inactive"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
