toolscore

claude

Correct tool calls are not enough: audit MCP servers (lint, scorecard, effect probes), turn agent traces into tool-call tests, check that an agent told the truth about what its tools did, and pin MCP servers against drift in CI.

api-platform

wso2/agent-skills 6

Idiomatic Go architecture and design. Teaches Claude the five design instincts that separate Go code from translated Java/Python: zero-value construction, consumer-defined interfaces, embedding over inheritance, typed constants, and stdlib-first development. Proven: 10% to 60% interface usage rate, non-coder with skill beats CS-dev without.

Human-Frontier-Labs-Inc/human-frontier-labs-marketplace 6

Set up and use the OpenCode 'zen' model harness in any project — route agent work to cheaper models by capability (fast=kimi-k2.6, reasoning-heavy/code-generation=glm-5.2) to save Claude's token budget, with Claude orchestrating and validating. One-command setup writes ~/.config/vinay-agent/config.toml and tests both models end-to-end; ask.sh calls a profile; /opencode-harness command included. Built by dogfooding — measured routing findings included. Use when integrating OpenCode, offloading reasoning/codegen to a cheap endpoint, or deciding which model a task should go to.
