## Why Codex Apps tools can mark arguments with `openai/fileParams`, but the execution path resolved and opened those files directly on the host. That bypassed the selected turn environment and prevented annotated file arguments from working with remote environments. ## What changed - resolve annotated file arguments against the primary turn environment - read file metadata and contents through that environment's sandboxed `ExecutorFileSystem` - reject files over the 512 MiB limit from metadata before reading or transferring them - retain the buffered upload-size check as defense in depth - make the OpenAI upload API accept a filename and buffered contents instead of owning local filesystem access - describe the model-visible argument as a path in the primary environment This builds on #27927, which added `size` to internal filesystem metadata. ## Testing - `just test -p codex-api upload_openai_file_returns_canonical_uri` - `just test -p codex-mcp tool_with_model_visible_input_schema_masks_file_params` - `just test -p codex-core mcp_openai_file` - `just test -p codex-core codex_apps_file_params_upload_environment_files_before_mcp_tool_call`

codex-api
Typed clients for Codex/OpenAI APIs built on top of the generic transport in codex-client.
- Hosts the request/response models and request builders for Responses and Compact APIs.
- Owns provider configuration (base URLs, headers, query params), auth header injection, retry tuning, and stream idle settings.
- Parses SSE streams into
ResponseEvent/ResponseStream, including rate-limit snapshots and API-specific error mapping. - Serves as the wire-level layer consumed by
codex-core; higher layers handle auth refresh and business logic.
Core interface
The public interface of this crate is intentionally small and uniform:
-
Responses endpoint
- Input:
ResponsesApiRequestfor the request body (model,instructions,input,tools,parallel_tool_calls, reasoning/text controls).ResponsesOptionsfor transport/header concerns (conversation_id,session_source,extra_headers,compression,turn_state).
- Output: a
ResponseStreamofResponseEvent(both re-exported fromcommon).
- Input:
-
Compaction endpoint
- Input:
CompactionInput<'a>(re-exported ascodex_api::CompactionInput):model: &str.input: &[ResponseItem]– history to compact.instructions: &str– fully-resolved compaction instructions.
- Output:
Vec<ResponseItem>. CompactClient::compact_input(&CompactionInput, extra_headers)wraps the JSON encoding and retry/telemetry wiring.
- Input:
-
Memory summarize endpoint
- Input:
MemorySummarizeInput(re-exported ascodex_api::MemorySummarizeInput):model: String.raw_memories: Vec<RawMemory>(serialized astracesfor wire compatibility).RawMemoryincludesid,metadata.source_path, and normalizeditems.
reasoning: Option<Reasoning>.
- Output:
Vec<MemorySummarizeOutput>. MemoriesClient::summarize_input(&MemorySummarizeInput, extra_headers)wraps JSON encoding and retry/telemetry wiring.
- Input:
All HTTP details (URLs, headers, retry/backoff policies, SSE framing) are encapsulated in codex-api and codex-client. Callers construct prompts/inputs using protocol types and work with typed streams of ResponseEvent or compacted ResponseItem values.
