fix(api): accept OpenAI-style multimodal message content for vision - #563
fix(api): accept OpenAI-style multimodal message content for vision#563seonghobae wants to merge 5 commits into
Conversation
_validate_messages required every message's content to be a plain
string, so any vision-capable caller sending the standard content-parts
array (`[{"type": "text", ...}, {"type": "image_url", "image_url":
{"url": "data:...;base64,..."}}]`) was rejected with invalid_message --
the same "channel silently degrades to unavailable" failure this
codebase's pluggable-client discipline exists to prevent everywhere
else. A concrete caller: LineageWeave's image OCR/captioning channel,
which needs a real vision round trip through this gateway, not a
placeholder.
_validate_message_content now accepts a validated content-parts list
alongside plain text. Routing/complexity-hint code (_latest_user_text,
_needs_workflow, the mock provider) never received a list before, so
those now go through a new _message_content_text helper that extracts
just the text parts for routing purposes -- the image itself is opaque
to routing and reaches the provider verbatim in the actual request.

PR #563's Semgrep gate was failing on 5 findings, all pre-existing code untouched by this PR: 3 raw-SQL-concatenation warnings in cost_ledger.py and 2 (unverified SSL context, dynamic urllib use) in orchestrator.py. Each already carried a `# nosec` comment explaining why it's safe (fixed placeholder characters and column names, never attacker-controlled; SSL verification opt-out is explicit and dev-only; the urlopen request URL is validated before this call) -- but `# nosec` is Bandit's suppression syntax, and the CI gate runs Semgrep, which does not recognize it. Added matching `# nosemgrep: <rule-id>` comments (verified locally against the exact rule IDs the CI gate reported: each rule fires without the comment and is silently suppressed with it, confirmed by toggling each suppression on/off and rerunning `semgrep --config r/<rule-id>` directly). Full suite still green (302 passed). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

…er validation
Strix flagged _validate_provider (MEDIUM, CVSS 4.7): its is_private/
is_loopback/is_link_local/is_multicast/is_reserved checks omit
ip_address.is_unspecified, and its report claimed "none of the current
checks return True" for 0.0.0.0/[::], letting them bypass the
non-public-address rejection.
Verified this specific factual claim directly before trusting it:
`ipaddress.ip_address("0.0.0.0").is_private` is actually already True
in CPython (0.0.0.0/8 is classified private per RFC 6890's IANA
registry, which the stdlib's is_private implements) -- so 0.0.0.0 and
[::] were already rejected before this change; Strix's report was
wrong on that specific point.
Added the explicit is_unspecified check anyway: relying on
is_private's incidental coverage of the unspecified range is fragile
and non-obvious to a reader (or a future refactor), whereas checking
is_unspecified directly says what is actually meant. New regression
test asserts both addresses are rejected. Full suite green (302
passed).

CodeRabbit review on this PR (accept OpenAI-style multimodal message content for vision): conduct()'s generated step prompts are built from `_latest_user_text`, which is text-only by design (routing/complexity heuristics only, per its own docstring). Every step message was then synthesized as a plain string, so a vision request that falls into the conduct workflow path (e.g. triggered by an "analyze" hint) silently lost its image_url part before ever reaching a provider -- defeating this PR's own purpose for exactly the request shape most likely to need a multi-step workflow (an image analysis task). New _message_image_parts() extracts the original user message's non-text content parts once, before the step loop; each step's user message becomes a content-parts list (synthesized text + original image parts) instead of a plain string whenever the original request had any. Plain-text requests are unaffected (image_parts is empty, so the content stays a plain string exactly as before). New regression test proves every step in a generated workflow receives the original image_url part, and fails on the pre-fix code (confirmed by reverting the fix locally and re-running). Full suite green (304 passed). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
