A [FILE:] marker in a user message is resolved analogously to [IMAGE:…]: local path, optional remote fetch gated by MultimodalFileConfig.allow_remote_fetch, data: URIs rejected. Resolution shape: - Extractable formats (PDF, TXT, CSV, MD) → FilePayload::Extracted — text inlined into the LLM payload, wrapped in [FILE-EXTRACTED: name="…" size="…" mime="…"]…[/FILE-EXTRACTED]. - Binary formats (ZIP, XLSX, DOCX, PPTX, generic) → FilePayload::Reference — metadata-only block: [FILE-ATTACHED: name="…" size="…" mime="…" sha256_prefix="…"]. Agent can mention the file without seeing raw bytes. Implementation notes: - pdf_extract::extract_text_from_mem wrapped in spawn_blocking + tokio::time::timeout(60s); on timeout / parse error / worker panic the file degrades to FilePayload::Reference so the chat turn still completes (avoids Sentry flood on hostile PDFs). - Extracted text truncated to MultimodalFileConfig.max_extracted_text_chars via .chars().take(N) with TEXT_TRUNCATION_SUFFIX byte-reserve to preserve the configured budget. UTF-8-safe at codepoint boundary. - detect_file_mime layers Content-Type header → extension table → magic bytes (%PDF-, PK\x03\x04) → UTF-8 sniff fallback. OOXML formats share the ZIP magic so the extension is authoritative for xlsx/docx/pptx vs plain zip. - Existing image pipeline untouched on the happy path; image-only callers see identical behavior. Image-marker tests remain green unmodified except for the prepare_messages_for_provider signature. - prepare_messages_for_provider now takes &MultimodalFileConfig as a third argument. The new param is threaded through run_tool_call_loop / run_simple_loop, AgentTurnRequest, and ChannelRuntimeContext so the call site at tool_loop.rs:450 can pass the user-configured value. - Files do NOT trigger the provider vision-capability gate at tool_loop.rs:427 — they inline as text and need no vision support. - Diagnostic logs use the stable [multimodal::files] prefix at debug/info/warn so traces are grep-friendly per CLAUDE.md. Module size note: multimodal.rs grows from 447 → ~880 lines, crossing the ~500-line soft cap. Splitting into a multimodal/ submodule is the intended follow-up — kept in one file here to keep the diff scoped and reviewable. --- src/openhuman/agent/bus.rs | 7 +

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds 16 unit tests covering the [FILE:…] pipeline introduced in the previous commit. Existing 8 image-marker tests stay green unmodified (backward-compat assertion). Coverage map: - parser: multi-marker extraction, empty-marker preservation, non-interference with [IMAGE:…] markers - extraction per format: TXT, CSV, MD (utf-8 decode + inline) and PDF (round-trips a hand-rolled minimal PDF skeleton; tolerant of pdf-extract degrading to Reference on hosts that cannot parse it, which still proves the file flowed through the extraction branch) - binary handling: ZIP magic (PK\x03\x04) → FILE-ATTACHED reference with sha256_prefix, no inlined text - rejection paths: oversized file, too-many files, unsupported MIME (error includes the supported list), remote URL when fetch disabled, data: URI for [FILE:…] (intentional rejection — not the data-URI contract images use) - safety: extracted text truncation respects the configured cap and the suffix-byte reserve so the final string stays inside the budget; UTF-8 chars never split mid-codepoint - regression: mixed image + file markers in one message both resolve; PreparedMessages.contains_images and .contains_files both true - helpers: file_mime_from_extension / file_mime_from_magic table coverage; MultimodalFileConfig.effective_limits clamps to bounds; case-insensitive MIME allowlist; FilePayload renders the …truncated suffix inside compose_multimodal_message PDF fixture is a 700-byte inline literal — no binary artifact in the git tree.

charset=UTF-8 Content-Transfer-Encoding: 8bit Production web-chat (Agent::turn) and other paths that go through the session loop in src/openhuman/agent/harness/session/turn.rs were bypassing the multimodal pipeline entirely — [IMAGE:…] / [FILE:…] markers from user messages were forwarded to the LLM verbatim instead of being resolved into data URIs / extracted text. The provider then sees prompts like "Read [FILE:/tmp/foo.txt]" with no way to act, and either confabulates or (with reasoning-v1) returns an empty response that the web channel renders as a generic error. This pre-existing gap also affected images attached via app/src/lib/attachments.ts whose docstring promised "the Rust backend parses these markers in parse_image_markers" — a promise the production turn loop never kept. The only call site of multimodal::prepare_messages_for_provider was tool_loop.rs, used by the bus.rs ad-hoc agent path (CLI / channel one-shots), not the session-based web chat. Fix: call prepare_messages_for_provider after to_provider_messages / budget-trim but before the provider request. Source the two configs from Agent::integration_runtime_config (populated for orchestrator sessions via build_session_agent_inner) and fall back to defaults otherwise. The clone cost per iteration is a few strings + four usizes — negligible against the provider RTT. The pipeline early- returns when the latest user turn has no markers, so this is a no-op for plain-text chats. Side effect: existing [IMAGE:…] markers now work end-to-end in web chat for the first time. No new public API; no new Agent / AgentBuilder fields; no test fixtures touched. --- src/openhuman/agent/harness/session/turn.rs | 24 +++++++++++++++++++++ 1 file changed, 24 insertions(+) diff --git a/src/openhuman/agent/harness/session/turn.rs b/src/openhuman/agent/harness/session/turn.rs index 82f77208d5..0a36d5a90e 100644 --- a/src/openhuman/agent/harness/session/turn.rs +++ b/src/openhuman/agent/harness/session/turn.rs @@ -678,6 +678,30 @@ impl Agent { } } + // Resolve [IMAGE:…] / [FILE:…] markers in user messages + // BEFORE the provider request.

Once the multimodal pipeline was wired into Agent::turn (C6) and exposed to long-running web-chat threads, this caused the per-turn caps (max_images, max_files) to drift upward over the conversation — turn N counted markers from turns 1..N-1 even though those messages had already been resolved in their original turns. Live-tested regression: a thread that attached 1 file per turn hit max_files=4 by turn 4 with errors like "multimodal file limit exceeded: max_files=4, found=13" even though the most recent user message contained a single marker. Fix: count markers only in the most-recent user-role message (extracted via a new latest_user_message helper). Matches user intent ("how many am I attaching THIS turn") and keeps the cap stable. Regression test asserts: - N markers in turn 1 + 1 marker in turn 3 → count_file_markers == 1 - Markers in history with plain-text current turn → count == 0 - Same per-turn semantics for the image counter (the original bug was symmetric across both pipelines) --- src/openhuman/agent/multimodal.rs | 28 ++++++++++++++------ src/openhuman/agent/multimodal_tests.rs | 34 +++++++++++++++++++++++++ 2 files changed, 54 insertions(+), 8 deletions(-) diff --git a/src/openhuman/agent/multimodal.rs b/src/openhuman/agent/multimodal.rs index fae8c56321..78fe080958 100644 --- a/src/openhuman/agent/multimodal.rs +++ b/src/openhuman/agent/multimodal.rs @@ -165,18 +165,29 @@ pub fn parse_image_markers(content: &str) -> (String, Vec) { (cleaned.trim().to_string(), refs) } +/// Count `[IMAGE:…]` markers in the **latest** user message only. +/// +/// Earlier versions summed markers across every user-role message in +/// the history, which made the per-turn `max_images` cap drift upward +/// over a long conversation: a thread that attached three images on +/// turn 1 already counted them again on turn 2 even when the new user +/// message had no attachments at all.

Mirror the triage-arm hardening: override multimodal_files at the per-turn application site with MultimodalFileConfig:: for_untrusted_channel_input() (max_files=0, allow_remote_fetch=false) regardless of operator default. The desktop / web-chat path (where the user owns the local filesystem) goes through a different turn builder and keeps the operator-supplied config. Also fix the pre-existing latent bug in prepare_messages_for_provider: effective_limits clamps max_files=0 up to 1, so a single [FILE:/etc/passwd] would slip through (1 > 1 is false). Add a pre-clamp gate that honours max_files=0 as the rejection sentinel, which is what the triage arm was already documented to rely on. Consolidate triage's existing inline {max_files: 0, ..Default} onto the new for_untrusted_channel_input() constructor so both untrusted paths route through one named hardening primitive.
