Remove dynamic x-anthropic-billing-header lines from Claude system prompts
when translating to OpenAI format to keep prompt prefixes stable and improve
prompt cache hits.

convertOpenAIToolChoice mapped {type:"function"} verbatim and cloakClaudeTools
left tool_choice.name unsuffixed, both rejected by Claude on the cc/ path.
Map forced-function to {type:"tool",name}, allowlist Claude-valid types, and
suffix tool_choice.name when it targets a renamed client tool.
Fixes#1592

Kiro requires a non-empty currentMessage tools array whenever history
references any tool use, else returns "Improperly formed request" (400).
Clients trip this by omitting tools on follow-ups after client-side
compaction.
- flattenToolInteractions(): no client tools -> collapse tool_use/result
to text so the "tools required" rule never fires
- reconcileOrphanedToolResults(): client tools -> salvage orphaned
results as text, keep matched ones, guard co-located tools array
- safeJSONParse(): guard tool-call argument parsing against bad JSON
- merge consecutive user userInputMessageContext; null-guard
currentMessage for assistant-only input

* fix: sanitize Read tool args to prevent retry loops from non-Anthropic models
* fix: sanitize invalid Read pages from tool args
Non-Anthropic models sometimes emit optional Read args like pages: "" for
non-PDF files, which Claude Code rejects before the tool runs. Drop invalid
pages values, keep valid PDF page ranges, and coerce numeric string bounds
before clamping limit/offset.

Some OpenAI-compatible providers emit optional string tool parameters
as empty strings (e.g. pages: "") instead of omitting them. Claude
Code rejects pages: "" as invalid, breaking the Read tool for
non-PDF files routed through 9router.
Add sanitizeToolArguments() that parses tool-call arguments and
removes known optional empty-string fields before emitting
input_json_delta back to Claude format. Currently handles the
Read tool pages field specifically.
Includes regression test.
Fixes#1278

## Features
- Add Vercel AI Gateway provider support (#1183)
- rtk: Kiro format tool result compression — handle conversationState.history & currentMessage, preserve error results, ~13.6% savings (#1194)
## Fixes
- openclaw: normalize agent.model object form `{primary, fallbacks}` before .startsWith → fix TypeError & 'not configured' status (#1216)
- Usage Details pagination: stay inside mobile viewport <640px (#1218)
- Fix test model error
- Fix MIMO provider in Codex
- Disable log file creation when using MITM AG
Deepseek API (and likely other providers) reject messages with
role: 'developer' — only accept system, user, assistant, tool.
filterToOpenAIFormat() normalizes content blocks but never touched
message roles, so developer passed through unmodified and caused
400 errors (issue #773).
Fix: add one-line developer → system mapping in filterToOpenAIFormat()
before role-specific logic. This is the common normalization point
called for all targetFormat=openai providers (Deepseek, Groq, Mistral,
Perplexity, Together, Fireworks, Cerebras, xAI, NVIDIA, etc.)
Closes#773
Add input_audio and audio_url content type handlers to
convertOpenAIContentToParts() in geminiHelper.js, converting
OpenAI audio format to Gemini inlineData format.
Also add audio types to VALID_OPENAI_CONTENT_TYPES in
openaiHelper.js so they are not stripped by filterToOpenAIFormat().
Fixes#912
- BaseUrlSelect: add cloud endpoint option, custom URL local state, always
default to first option; new cliEndpointMatch helper; CLI tool cards refactor
- API: new /v1/audio/voices and /v1/models/info; /v1/models filters disabled
models, drop unused timestamp
- initializeApp: guard tunnel/tailscale auto-resume to once-per-process
- geminiHelper: ensureObjectType for schemas with properties but no type
- skills: minor SKILL.md tweaks (chat/embeddings/image/stt/tts/web-*)
- Refactored handleChatCore to include Caveman functionality, allowing for terse-style system prompts to reduce output token usage.
- Updated APIPageClient to manage Caveman settings, including enabling/disabling and selecting compression levels.
- Adjusted AntigravityExecutor to consolidate function declarations for compatibility with Gemini.
- Removed unnecessary console logs during translator initialization across multiple routes.
- github.js: split thinking vs reasoning_effort stripping
- thinking (Claude-native format) still stripped for all Claude on Copilot
- reasoning_effort now passed through for Opus 4.6 and Sonnet 4.6
- still stripped for Haiku 4.5 and Opus 4.7 (rejected upstream)
- reasoning_effort "none" stripped for all models (not all support it)
- openai-to-claude.js: map reasoning_effort → thinking.budget_tokens
for direct Anthropic backend (none→skip, low→4096, medium→8192,
high→16384, xhigh→32768)
Previously reasoning_effort was stripped for ALL Claude models,
meaning Opus 4.6 via Copilot never received thinking configuration.
AI-generated commit by Claude Opus 4.6 (Anthropic)
Remote HTTP(S) image URLs are fetched and inlined as base64 data URIs
in a new prefetchImages() step run before super.execute(), so the body
sent to Codex contains resolved image bytes instead of URLs the backend
cannot access.
Scope is limited to the Codex executor — base executor and other
providers are untouched.

Closes#433
Made-with: Cursor
Apply fix from PR #354 by @tannk4w to properly signal tool_calls finish_reason
when model emits tool calls, allowing OpenAI-compatible clients to continue with
tool result processing instead of stopping prematurely.
Refactored finish_reason logic into computeFinishReason() helper to eliminate
duplication and improve maintainability across flush and completion paths.
