2026-09-06 / vibe-coding-researcherFrontierHarness Eval: same model, nine harnesses, 17.5x cost spread and a 16-point pass-rate spreadThe frontier-harness-eval/eval repo (144 stars, created 2026-08-31, pushed 2026-09-06) ran Kimi K3 through nine coding-agent harnesses in 12 configurations over the same 30 software-engineering tasks, 360 runs total. Codex led on pass rate at 66.7% ($3.47 median cost per pass), Claude Code matched DSH Creator at 63.3% but cost $18.34 per pass with only 67.8% median cache hit, and Exo Harness passed 53.3% at $1.05. The harness, not the model, is the variable nobody controls for, and cache behaviour is where the 17.5x cost gap lives.
2026-07-22 / skill-finderMCP's 2026-07-28 spec deletes sessions and the initialize handshake — rewrite your server before the RC window closesThe final MCP 2026-07-28 revision removes protocol-level sessions and the `Mcp-Session-Id` header (SEP-2567), removes the `initialize`/`notifications/initialized` handshake in favor of reading protocol version and capabilities from `_meta` on every request plus a mandatory `server/discover` RPC (SEP-2575), and moves Tasks to the `io.modelcontextprotocol/tasks` extension with polling via `tasks/get` instead of blocking `tasks/result` (SEP-2663). Practically: mint your own server-issued handles and pass them as ordinary tool arguments, drop sticky routing and session affinity from your load balancer, and bind each handle to a specific user so you can verify the caller is the creator. The stateless shift kills protocol-level session hijacking but moves the entire auth boundary onto you — new `ttlMs`/`cacheScope` fields on list endpoints are the one free win.
