buildOne report1 publisher Swapping the scaffold moved Claude Opus 4.5 from 42% to 78% on CORE-Bench
The same model scored twice under two scaffolds. A dev.to post uses that gap to argue the dividing line in AI coding is whether the model can run your repo's own commands and read the failure.

buildOne report1 publisher A co-authored-by search for Cursor's name returned 10,033,042 public commits
The trailer Cursor actually writes keys on an address, so a search on the display name pulls in every co-author who shares it. Switching to addresses moved one developer's Claude count by seven commits.

Grok 4 fails half its patch attempts on Codex's edit format
Coding-agent failures cluster in the plumbing between knowing what to change and changing it. One harness builder measured what that costs and published the failure rates for Grok 4 and GLM-4.7.

buildOne report1 publisher Claude Code picks up Monday from the correction card Codex wrote on Saturday
klypix-mcp keeps a team's changing decisions in a brain.klypix file inside the repo, where a correction supersedes a stale card and keeps its history. How much it helps depends on whether the host actually calls the tools.

buildOne report1 publisher A compiler gate in a shadow worktree decides which LLM patch reaches the repo
Sergi Corruchaga reports his D-Engine harness produced the same diff as DeepSeek's official agent on 42 times fewer tokens, by letting the model propose SEARCH/REPLACE blocks and a local runtime apply them.

buildOne report1 publisher The archrule glob makes your package tree the architecture spec
The New Stack's case for moving architecture rules out of the wiki and into pytest holds up on mechanism. The two sample rules also show the bill: enforcement runs on module-name globs, and the domain-purity check bans two libraries where its own docstring promises an allowlist.

buildOne report1 publisher The compatibility probe wore the one User-Agent the CDN rule allowed
A CDN rule aimed at AI crawlers matched the Vendor/Language User-Agent shape that the official OpenAI and Anthropic SDKs send by default. The harness meant to catch it sent an allowlisted string of its own and reported green.

buildOne report1 publisher Harness choice moved token use 83-fold with the model held constant
The spread traces to two numbers you can read off your own logs: the tokens a harness spends before any work starts, and how many turns it takes. Together they predicted total token use with an R-squared of 0.99.

Four leaderboards, four denominators: what you buy when you standardize on a coding agent
Token traffic, survey reach and production-model ledgers rank different vendors because they count different things. The autonomy figures say the hard part is still unbought.

Hermes Agent treats the runtime as the durable asset and the model as a swappable input. The lock-in moves into your own repo, and the administrator's job moves with it.

buildOne report1 publisher Your Coding Agent Reads .env, And .gitignore Was Never The Control
A dev.to writeup makes a point worth stealing: the secret leaves your machine in a prompt, not a commit. The proposed fix is a local proxy that masks values before egress.
