From Skills to Talent: Organising Heterogeneous Agents as a Real-World Company

106 upvotes · Yu et al. · Paper

OneManCompany (OMC) transforms multi-agent systems from fixed pipelines into self-organizing AI companies that can hire, fire, and restructure themselves. The framework introduces portable "Talents" (agents with skills), a community marketplace for recruiting new capabilities on-demand, and an Explore-Execute-Review loop that mirrors corporate feedback cycles. On PRDBench, OMC achieved 84.67% success rate—15.48 percentage points above state-of-the-art—while providing formal guarantees against deadlocks and infinite loops.

ReVSI: Rebuilding Visual Spatial Intelligence Evaluation for Accurate Assessment of VLM 3D Reasoning

59 upvotes · Zhang et al. · Paper

Current 3D reasoning benchmarks for vision-language models are systematically broken due to annotation artifacts from point-cloud data and assumptions about full-scene access. ReVSI fixes this by re-annotating 381 scenes across 5 datasets using professional 3D tools and generating QA pairs that are actually answerable from sparse video frames (16-64 frames). The benchmark reveals failure modes in both general and domain-specific VLMs that were previously hidden by flawed evaluation protocols.

Recursive Multi-Agent Systems

54 upvotes · Yang et al. · Paper

RecursiveMAS extends the recursive scaling principle from single models to multi-agent collaboration, where agents iteratively refine their joint computation through latent-space loops rather than text exchanges. The framework delivers 8.3% average accuracy improvement over baselines while achieving 1.2-2.4× speedup and 35-76% token reduction across mathematics, science, and code generation benchmarks. The key insight: agent collaboration itself can be scaled through recursive computation, not just individual model depth.

🛠 Tools

mattpocock/skills — Professional AI agent skills for real engineering

7321 stars/day · Repo

Matt Pocock's collection of Claude/Codex skills designed for actual engineering work, not "vibe coding." The 40k-star repo includes composable skills for triaging issues, creating specs, and managing development workflows that work across different AI models. The skills emphasize small, adaptable components that give developers control while preventing common agent failure modes—a practical alternative to heavyweight process frameworks.

Alishahryar1/free-claude-code — Free Claude Code access via terminal and VSCode

1741 stars/day · Repo

A Python tool that provides free access to Claude Code functionality through terminal, VSCode extension, or Discord integration, similar to existing openclaw implementations. The project offers an alternative access method for developers who want Claude's coding capabilities without direct API costs, though specifics about the implementation approach aren't clear from the basic description.

abhigyanpatwari/GitNexus — Zero-server code intelligence with knowledge graphs

1607 stars/day · Repo

GitNexus creates interactive knowledge graphs of any codebase entirely in the browser, analyzing dependencies, call chains, and execution flows without requiring a server. The 33k-star TypeScript project includes a built-in Graph RAG agent for code exploration and integrates with AI tools like Cursor and Claude Code through CLI/MCP to give agents deep architectural context. It's positioned as going beyond code understanding tools like DeepWiki by focusing on relationship analysis rather than just descriptions.

Quoting OpenAI Codex base_instructions

28th April 2026 · Post · tags: openai, system-prompts, prompt-engineering

Simon shares a curious system prompt instruction from OpenAI's Codex base instructions for GPT-5.5: "Never talk about goblins, gremlins, raccoons, trolls, ogres, pigeons, or other animals or creatures unless it is absolutely and unambiguously relevant to the user's query." While brief, this oddly specific constraint hints at either training data contamination issues or attempts to prevent certain types of anthropomorphic reasoning patterns in code generation contexts.

What's new in pip 26.1 - lockfiles and dependency cooldowns!

28th April 2026 · Post · tags: packaging, python, security, supply-chain

Python's default pip tool gets major upgrades with proper lockfiles (generating detailed pylock.toml files) and dependency cooldowns for supply-chain security. The --uploaded-prior-to PXD option lets developers specify minimum package age to avoid newly-uploaded malicious packages—a practical defense against supply chain attacks. These features bring pip closer to modern package managers like npm and cargo while addressing real security concerns in Python dependency management.
