When no providers are available, reduce all cooldowns by 1 minute.

[letanloc1998]

Context

Fallback recovery: When no providers are available, reduce all cooldowns by 1 minute.
This allows the next adjustActiveHandler() call to potentially find an available provider without waiting for the full cooldown duration.

Implementation

When all providers are unavailable.
Reduce each provider's cooldown by 1 minute to progressively unblock them.
This creates a "soft recovery" mechanism where providers gradually become available rather than waiting for full cooldown expiry.

Current setCooldown Usage

setCooldown() is now only used in error handling (line 101-115):

• Rate limit errors (429): 10min cooldown → switch provider → retry
• Other errors: 10min cooldown → rethrow (not all errors are provider-related) => recovers via reduceCooldown when no handlers available

Lines 101 to 115 in 112574a

	if (this.isRateLimitError(error) || this.isOverloadError(error)) {
	// Set cooldown for the current provider
	await this.usage.setCooldown(this.activeProfileId, 10 * 60 * 1000)
	// Switch to a different provider
	await this.adjustActiveHandler("Retryable Error")
	// Retry the request with the new provider
	yield* this.createMessage(systemPrompt, messages, metadata)
	return
	}
	// For non-rate limit errors, set cooldown and rethrow
	await this.usage.setCooldown(this.activeProfileId, 10 * 60 * 1000)
	throw error

This is a solid idea.
