Cut Your Coding Agent's Cost and Context

This skill reads the user's own Claude Code sessions from LangWatch, runs one check per recommendation below, and reports only the recommendations their data supports. Every recommendation names the evidence, the exact setting and an expected saving, and says whether that saving was measured in a controlled run or estimated from token counts. It is read-only on the platform and leaves one report file behind.

Step 1: Set up the LangWatch CLI

Use the langwatch CLI for everything: documentation (langwatch docs ..., langwatch scenario-docs ...) and platform operations (prompts, scenarios, evaluators, datasets, monitors, traces, analytics). Install it once with npm install -g langwatch, then run the langwatch binary directly; an unpinned npx langwatch re-resolves the package from the registry on every run.

Coding-agent sessions live in the user's personal LangWatch workspace by default. langwatch login --device signs this machine in; add --project <slug> on every read command when the sessions live in a team project instead.

Use langwatch docs <path> to read documentation as Markdown. Some useful entry points:

langwatch docs                                    # Docs index
langwatch docs integration/python/guide           # Python integration
langwatch docs integration/typescript/guide       # TypeScript integration
langwatch docs prompt-management/cli              # Prompts CLI
langwatch scenario-docs                           # Scenario docs index
