→ To do: audit your own overhead once: check your session's token count before typing anything (in Claude Code, /cost after one trivial message). Then prune — every MCP server, skill and tool definition you keep loaded is paid on every session, whether used or not.
A production migration to GPT-5.6, with numbers: 2.2× faster, 27% cheaper. Rare non-benchmark data — a team moved a production agent and published latency and cost deltas instead of vibes (251 points on HN). ) annotated 63,000+ steps across 1,794 CLI coding-agent trajectories, seven frontier models, three harnesses (OpenHands, MiniSWE, Terminus2). Findings: failures usually start in the first few execution steps, stay hidden until recovery is impossible, and are dominated by epistemic errors — the agent not knowing what it doesn't know.
→ To do: stop logging only pass/fail. Keep full trajectories, and put your one human checkpoint early (after the first commands run), not at the end — by the time the final answer looks wrong, the paper says it was usually unrecoverable long before.
Long-horizon benchmark lands, and nobody passes: 29 of 46 tasks unsolved.
→ To do: minimum bar even without new tools: run agents under a separate OS user with no SSH keys and no cloud credentials in env. A VM or container is better; your main account is worse.
The verifier business is now a unicorn. PI raised at a $1B+ valuation with $100M ARR, selling verifiers — the machinery that scores whether an agent's output is right. The market priced the bottleneck: evaluation, not generation. ); GPT-5.6 is simultaneously fresh in builders' hands.
→ To do: rare week where you can benchmark two frontier models on your own workload at low cost. Run the comparison now; both windows close.
Under the radar
(9★) — local-first, project-aware memory MCP server for Claude Code/Codex, with Obsidian sync. → One install gives all your agents shared memory across projects, on your disk not a SaaS.
— one issue a week, every item ends with something you can do, and if a week is slow I say so.↗ Original-Artikel auf dev.to lesenVollständiger Original-BerichtAusführliche Details, Code-Beispiele & Hersteller-Stellungnahme auf dev.to.
