Compaction cannot remove or +reorder the action messages the flow viewer indexes, or the MCP results it finds by call ID. + +Before each provider request, including the first, the worker checks the projected context size. +It reserves the larger of 20% of the model window and the configured maximum output tokens. +At the remaining input budget it summarizes an older prefix, retaining up to 20K estimated tokens +of recent complete exchanges (at most half the input budget on smaller models). +The newest exchange is always retained. A user prompt stays with its +first response; later tool rounds can be compacted within a single turn, but a call and its results +are never split. A prefix containing only an earlier summary is not summarized again. + +The summarization request carries no tools; its tool exchanges are rendered as text because +Bedrock rejects tool blocks without definitions. A dedicated system instruction asks for a factual +handoff from a labelled transcript, keeping the compaction instruction outside that transcript; +media parts remain available. Its output cap matches the reserved summary budget, +and its temperature and reasoning settings are independent of the step's answer settings. +A replacement is built separately and installed only if it reduces projected context and fits +the estimated input budget. An empty, oversized or failed summary leaves the context and its +usage measurement untouched; compaction never evicts messages. Three consecutive failed attempts +disable summary requests for the run. Estimates schedule compaction but do not reject model calls. + +The projection uses normalized `TokenUsage::input_tokens` from the last request plus a `bytes/4` +estimate of appended messages. Without usage, or after rewriting context, it estimates the whole +prompt including tools. S3 descriptors get a nominal attachment allowance; actual attachment costs +and tokenizer differences remain approximate. Provider parsing owns usage normalization: Anthropic +and Bedrock report cached input separately, while OpenAI-shaped providers include it in input tokens. +If a provider explicitly rejects the context size, the worker summarizes all older complete +exchanges and retries that request once if a usable replacement was produced. This also recovers +from undercounted attachments loaded from a previous run, without provider-specific tokenizers. +Unrelated errors are not retried this way. The newest exchange is still retained, so a request +that cannot fit even after recovery fails; estimates do not guarantee every first request fits. + +If recovery fails or the retry is rejected, the provider error is returned without saving changed +memory.

Persistence independently checks +serialized memory against the database's 100KB limit (`MAX_MEMORY_SIZE_BYTES`), +when `memory_storage_capacity_bytes` reports one. System messages and tool definitions are not +stored, so they do not count towards this byte limit. If oversized, it requests one checkpoint +of all older exchanges, then measures bytes again. If memory still cannot fit, persistence saves +the largest suffix of complete exchanges that fits and starts with a user message, dropping +older exchanges and logging that loss. This selection changes neither model context nor the +returned execution record. +If no user-starting suffix fits, the write is skipped and the flow log explains that the +next run will load the previous saved memory. The completed answer succeeds in either case. +If object storage fails and falls back to the database, an oversized compaction write is +rejected without changing existing memory; the flow log reports the failed save. +There is no model-window compaction after the final answer unless storage needs +it.

The implicit iterator is the iteration counter, so 'flow_input.iter.value' equals 'flow_input.iter.index' (0, 1, 2, ...) and never carries state. To carry state across iterations, a step reads its own previous-iteration result via 'results.' with a first-iteration fallback - the loop's stop_after_if must then be on that inner step (a plain single-step body with stop_after_if on the loop module does not resolve 'results' across iterations and never terminates); plain counters can instead be derived from 'flow_input.iter.index', which works in every configuration. stop_after_if is evaluated after each iteration - on the loop module 'result' is the last iteration's result","properties":{"modules":{"type":"array","description":"Steps to execute in each iteration","items":{"$ref":"#/components/schemas/FlowModule"}},"skip_failures":{"type":"boolean","description":"If true, iteration failures don't stop the loop.
