MERCADOPAGO V2 GOES LIVE, BUFFA AUDIT CLEARS CODEGEN DEBT
By RepoJournal · Filed · About Anthropic
MercadoPago plugin ships consolidated v2 architecture with HTTP MCP endpoints and smarter hook gating, while Buffa's codegen passes style audit with redundant clone removal across 6 sites.
The mercadopago plugin pins to 63ff263c, completing the v2 migration that replaces the keychain-read wrapper with a plain HTTP MCP entry and collapses 13 skills into 4 orchestration skills [1] [2]. That same SHA includes the May 19 PreToolUse hook fix that stops the hook from running on unrelated projects, cutting noise in agent bundles. Over in Buffa, the codegen audit wrapped up with two follow-up PRs clearing unnecessary Option/Result wraps and redundant clones [3] [4] [5]. The team also shipped linked descriptor types and dedup feature resolution in the descriptor module [6], laying groundwork for runtime reflection in subsequent PRs. Meanwhile, financial-services fixed 9 failing marketplace loader syncs by synthesizing proper YAML frontmatter across 29 vertical-plugin SKILL.md files [7] [8], and stamped metadata.anthropic_cookbook on managed-agent deploys for BigQuery attribution [9] [10]. Claude Agent SDK rolled to v0.2.83 with CLI 2.1.146 bundled in [11] [12] [13], and Claude Code Action hit v1.0.128 with matching CLI and SDK bumps [14] [15].
