Open Multi-Agent Files

Added

• Added runImage() for image generation and editing across an ordered chain of image models, with per-model retries that honor Retry-After, fallback on non-retryable failures, an optional validate check on each returned image, and a record of every provider call through result.attempts and onAttempt.
• Added the ImageModelAdapter interface and four built-in adapters that call provider HTTP APIs directly and honor egressPolicy: OpenAIImageAdapter (OpenAI Images API and OpenAI-compatible endpoints), SeedreamImageAdapter (Seedream on Volcengine Ark), OpenRouterImageAdapter (OpenRouter /images, sending input images as input_references), and BlackForestLabsImageAdapter (FLUX models, submit/poll/download).
• Added ImageModelError with normalized ImageModelErrorType values; isRetryableError() returns its retryable flag, its optional params carries details of already-accepted provider work such as a task ID and cost into the failed attempt record, and ImageCallOptions.maxRetryAfterMs tells an adapter that waits internally the longest Retry-After runImage() allows.
• Image adapters classify safety or moderation rejections, including upstream rejections forwarded in error.metadata, as non-retryable content_policy, fail rather than drop input they cannot use, and report the media type read from the returned image bytes.

Changed

• Enabling thinking without budgetTokens now sends adaptive thinking on Claude Opus 4.7, Sonnet 5, and later, which previously rejected the request with HTTP 400; pre-adaptive models keep the 1024-token budget default.
• The task profiler omits temperature for Claude models that reject non-default sampling parameters, avoiding HTTP 400 routing failures on Opus 4.7, Sonnet 5, and later.
• The bash tool description now states that it is not confined to the agent's working directory, prefers the file tools, grep, and glob for file work, and reports a non-zero exit code; built-in tool descriptions now match glob's path output, and the synthesis prompt no longer carries an unscoped JSON-only instruction.
• create-oma-app is republished as a patch so its templates pin the new core version exactly; otel is unchanged and keeps its semver range against core.

Fixed

• Enabling thinking without budgetTokens no longer produces HTTP 400 on current Claude models (Opus 4.7, Sonnet 5, and later); those models now receive adaptive thinking instead of an explicit budget.
• The task profiler no longer sends temperature to Claude models that reject non-default sampling parameters, fixing HTTP 400 routing failures on Opus 4.7, Sonnet 5, and later.

Compatibility

• No breaking changes: core public API changes are additive exports only, no export was removed, renamed, or narrowed, and no engines floor or published dependency major changed; isRetryableError() gains an answer for ImageModelError while all pre-existing error classes keep their prior answers, and no import path changes.
• Callers that pass an explicit thinking.budgetTokens on Claude Opus 4.7 or Sonnet 5 must still omit it; passing it explicitly still emits budget_tokens and is rejected with HTTP 400.
• Callers that relied on the implicit 1024-token thinking budget on Claude 4.6-generation models now get adaptive thinking and should re-check maxTokens and thinking-cost assumptions.
• If a model ID is routed through a proxy, alias, or non-canonical suffix, verify thinking and temperature behavior against that endpoint before upgrading: the legacy-model list in anthropic-models.ts is closed, and unknown IDs default to adaptive thinking and no temperature.
• For the new image adapters, supply credentials via apiKey or the environment (OPENAI_API_KEY, OPENROUTER_API_KEY, ARK_API_KEY, BFL_API_KEY); providerOptions keys that carry the request itself (prompt, model, n, input image fields, mask, response_format where applicable) are rejected with a TypeError at construction. A request's size overrides a providerOptions size default; Seedream watermark is set on the adapter, with providerOptions watermark overriding the adapter's watermark option. It has no per-request override.
• An egressPolicy allowlist used with the Black Forest Labs adapter must include the poll and download hosts in addition to the API origin.
• create-oma-app republishes as a patch so its templates pin the new core version exactly; already-generated projects keep working and can upgrade core independently.
• otel stays at its current version with its existing semver range against core; it is not republished and remains compatible with the new core.
