Reviewed all 20 open PRs — happy to help with the review queue

[Solaris-star]

Hi all 👋

I went through every open PR in the queue this week and left detailed reviews on all 20. A few patterns I noticed that might help with triage:

Urgent / security:

• fix(deserialization): replace pickle.loads with JSON across all sinks #2709 (pickle → JSON) is an RCE fix that has been open since April. The approach is sound (JSON-first with pickle fallback for reads). Worth prioritizing.

Ready to merge (pending maintainer sign-off):

• fix(spec): warn on unknown fields in AgentSpec instead of dropping them silently #3118, refactor(tools): home the tool abstractions in ag2.tools.types #3117, feat(middleware): add describe() so middleware can report its configuration #3120 (marklysze's own PRs) — clean, well-tested, just need a second pair of eyes
• feat(perplexity): add X-Pplx-Integration attribution header #2903 (Perplexity header) — small, correct, well-tested
• feat: add Kilo Code support and model selection to ACP configurations #3101 (Kilo Code + model selection) — straightforward wiring fix

Needs discussion before merge:

• agent memory: LongShortTermMemoryStorage #2568 (LongShortTermMemory) — 81 files, +2645/-4271. The design is solid but the scope makes it very hard to review safely. Suggested splitting into 3 PRs.
• Feat/elevenlabs live #3086 (ElevenLabs live) — 22 files. The provider abstraction is great, but the dependency handling needs clarification.

Middleware trilogy (#2531, #2532, #2533):
These three together are a clean replacement for the old GovernanceMiddleware. All well-structured and well-tested. The overlap with #2968 (TealTiger) and #3071 (cost accounting) should be documented so users know when to use which.

I'm particularly interested in the middleware system, MCP/tool integration, and the A2A protocol. Happy to keep helping with reviews, triage, and bug fixes in those areas.

If there's a process for regular contributors to get more involved (review permissions, issue triage, etc.), I'd love to know how to get there.

Cheers!
