Buffa bounds Any nesting; Claude Security Plugin v0.11.0 lands

By RepoJournal · Filed · About Anthropic

Three serialization-bound patches land in buffa while the official Claude plugins ship security release v0.11.0.

The Claude Security Plugin for claude-plugins-official shipped v0.11.0 [1], merged by Tobin South [2]. Also updated is /frontend-design SKILL.md to address "manatee slop measures" [3]. In buffa, two independent patches now bound recursion through nested google.protobuf.Any. Serializing a nested Any no longer expands each level without limit; [4] the reflective JSON serializer now threads a RECURSION_LIMIT (100) budget through to_json() to prevent a sub-megabyte input from overflowing the stack, which was an uncatchable abort [5]. Separately, buffa-build adds Config::exclude_package, matching protoc-gen-buffa's existing exclude_package knob since v0.6.0, for when directory globbing or --include_imports pulls in option-only packages like buf/validate/validate.proto [6]. Three more buffa fixes: repeated message values in one map entry now merge in view and reflective decoders, matching protobuf semantics [7]; Api, Type, and SourceContext join the JSON-mappable WKT set [8]. Meanwhile claude-agent-sdk-python released v0.2.151 and v0.2.150, both bumping the bundled CLI to 2.1.258 and 2.1.257 [9][10]; claude-code-action followed with v1.0.213 and v1.0.212, each carrying corresponding Agent SDK bumps [11][12].
