mcp-code-execution skillA

mcp-code-execution is agent-read markdown (skill) from athola/claude-night-market: Routes multi-tool workflows through MCP servers for large datasets and pipelines. Use when Bash tool overhead is limiting throughput on data-heavy tasks..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# MCP Code Execution Hub

## Quick Start

This skill is an orchestration hub, not a CLI. It activates
inside a Claude Code session when one of the trigger keywords
below appears, or when invoked explicitly:

```
Skill(conserve:mcp-code-execution)
```

The hub then routes to the relevant sub-skill modules
(`mcp-subagents`, `mcp-patterns`, `mcp-validation`) based on
the detected workflow shape. There is no separate install
step or CLI entry point.

## When To Use
- **Automatic**: Keywords: `code execution`, `MCP`, `tool chain`, `data pipeline`, `MECW`
- **Tool Chains**: >3 tools chained sequentially
- **Data Processing**: Large datasets (>10k rows) or files (>50KB)
- **Context Pressure**: Current usage >25% of total window (proactive context management)

> **MCP Tool Search (Claude Code 2.1.7+)**: When MCP tool
> descriptions exceed 10% of context, tools are automatically
> deferred and discovered via MCPSearch instead of being loaded
> upfront. This reduces token overhead by ~85% but means tools
> must be discovered on-demand. Haiku models do not support tool
> search. Configure threshold with `ENABLE_TOOL_SEARCH=auto:N`
> where N is the percentage.
