 - Sessions/Agents: pass `agentId` when resolving existing transcript paths in reply runs so non-default agents and heartbeat/chat handlers no longer fail with `Session file path must be within sessions directory`. (#15141) Thanks @Goldenmonstew.
 - Sessions/Agents: pass `agentId` through status and usage transcript-resolution paths (auto-reply, gateway usage APIs, and session cost/log loaders) so non-default agents can resolve absolute session files without path-validation failures. (#15103) Thanks @jalehman.
 - Signal/Install: auto-install `signal-cli` via Homebrew on non-x64 Linux architectures, avoiding x86_64 native binary `Exec format error` failures on arm64/arm hosts. (#15443) Thanks @jogvan-k.
+- Web tools/web_fetch: prefer `text/markdown` responses for Cloudflare Markdown for Agents, add `cf-markdown` extraction for markdown bodies, and redact fetched URLs in `x-markdown-tokens` debug logs to avoid leaking raw paths/query params. (#15376) Thanks @Yaxuan42.
