Tools: Code Is All You Need

> try completing a GitHub task with the GitHub MCP, then repeat it with the gh CLI tool. You'll almost certainly find the latter uses context far more efficiently and you get to your intended results quicker.

This is spot on. I have a "devops" folder with a CLAUDE.md with bash commands for common tasks (e.g. find prod / staging logs with this integration ID).

When I complete a novel task (e.g. count all the rows that were synced from stripe to duckdb) I tell Claude to update CLAUDE.md with the example. The next time I ask a similar question, Claude one-shots it.

This is the first few lines of the CLAUDE.md

    This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

    ## Purpose
    This devops folder is dedicated to Google Cloud Platform (GCP) operations, focusing on:
    - Google Cloud Composer (Airflow) DAG management and monitoring
    - Google Cloud Logging queries and analysis
    - Kubernetes cluster management (GKE)
    - Cloud Run service debugging

    ## Common DevOps Commands

    ### Google Cloud Composer
    ```bash
    # View Composer environment details
    gcloud composer environments describe meltano --location us-central1 --project definite-some-id

    # List DAGs in the environment
    gcloud composer environments storage dags list --environment meltano --location us-central1 --project definite-some-id

    # View DAG runs
    gcloud composer environments run meltano --location us-central1 dags list

    # Check Airflow logs
    gcloud logging read 'resource.type="cloud_composer_environment" AND resource.labels.environment_name="meltano"' --project definite-some-id --limit 50
