    This skill should be used when the user mentions "setup", "getting started", "install dependencies", "dev environment", "onboarding", "won't run", "version mismatch", "devcontainer", "env vars", "works on my machine", or a failing local install/build. It maps where a repo declares its runtime needs

Slash commands (4)

  • /codebase-navigator:build-explain

    Decode the build system and show how to build or test one package fast

  • /codebase-navigator:dev-env-bootstrap

    Get an unfamiliar repo running locally and emit a verified SETUP.md

  • /codebase-navigator:locate-change

    Given a task, find the exact files and functions to edit plus tests to update

  • /codebase-navigator:trace-flow

    Trace a user action end-to-end through the real call graph with a diagram

Subagents (3)

  • change-locator

    Use this agent when someone knows WHAT to change but not WHERE in the codebase to change it, task-scoped localization that returns the precise files, functions, and tests to edit. Trigger on "where do I add ...", "which file handles ...", "where is X implemented", "what do I need to touch to ...", "

  • env-doctor

    Use this agent when a repository won't run locally and you need it bootstrapped and green, detecting the required runtime/tooling versions and services, running the setup, and diagnosing failures. Trigger on "get this running", "set up the dev environment", "the install is failing", "wrong Node/Pyth

  • flow-tracer

    Use this agent when you need to understand what actually happens end-to-end when a request or user action runs, following routing, middleware, handlers, services, and data access across the real call graph. Trigger on "trace this request", "what happens when a user clicks X", "walk me through the lo

Twelve structured monitoring and evaluation document reviews: logframes, theories of change, indicators, evaluation TORs, M&E plans, proposals, sampling plans, surveys, baseline reports, progress reports, data quality assessments, and evaluation reports. Each returns section-by-section PASS/PARTIAL/FAIL ratings, a summary verdict, and prioritized recommendations.

Builds up to a goal in a field you have no expertise in: splits it into the foundations that goal actually needs, mobilizes what you already hold, learns what is missing, and leaves every solved path behind for the next goal. Nothing is called done until a check passes.
