The result-interception hook (#41202) is a place to redact secrets or strip injected instructions out of untrusted MCP output before it enters context, which is the missing seam in every MCP setup I've built. Also: a configurable grace period for discovering tools from optional MCP servers (#41199), plugin catalogs combining per-repo config while reporting invalid project marketplaces without hiding valid plugins (#41208), nested subagent token usage counted toward root goal budgets (#41183), and stale Guardian classifications no longer authorizing actions after permission state changes (#41196).

Released 01:58 UTC on September 1, demoting update_plan to opt-in, so you need tools.update_plan.enabled = true in config to get planning back (GitHub). It also adds output_token_limit per individual MCP tool with truncation that survives session resume, allows :, @, / and . i...
Three things happened this month that only make sense together. Agent Plugins 1.0 shipped co-signed by six competitors: AWS, Anysphere, Microsoft, OpenAI, Vercel and Google (GitHub Changelog). It makes skills-plus-MCP bundles portable across clients. OpenAI's August 11 Codex c...
Language packs like samber/cc-skills-golang, 1,600-plus cross-tool libraries, harnesses like DeerFlow with built-in skills, even Google's Workspace CLI bundling agent skills. The unit of reuse shifted from prompts and MCP tools to portable markdown skills that travel across Cl...
EchoVault solves the "agent amnesia" problem — coding agents forgetting everything between sessions. It runs as an MCP server giving agents three tools: memory_context (load prior decisions), memory_search (find specific memories), and memory_save (persist learnings). Storage...
The most under-hyped tool of the week is a single Rust binary with zero dependencies that sits between your coding agent and your terminal, compressing command outputs before they hit the context window. rtk (Rust Token Killer) intercepts common dev commands — cargo test, git...
rust-v0.150.1, published August 27, fixes remote compaction ignoring retained images when computing token budget; it now trims older images as needed (GitHub). Sessions passing screenshots to a vision-capable agent were budgeting as though those images cost nothing, which prod...
