gitnexus-exploring

GitNexus Exploring is a codebase-comprehension skill that helps an AI assistant answer questions like "How does authentication work?", "What calls this function?", or "Show me the payment flow" by navigating a pre-indexed model of a repository rather than reading source files blindly. It solves the problem of understanding unfamiliar or large codebases, where grepping and guessing about execution paths is slow and error-prone, by giving the agent structured overviews, symbol relationships, and traced execution flows.

The skill defines a fixed workflow over a set of `gitnexus://` MCP resources and two tools. It reads a repo context resource (stats plus a staleness warning), then uses a `query` tool to find execution flows related to a concept (returning named processes such as CheckoutFlow or RefundFlow with their symbols and file locations), and a `context` tool to get a 360-degree view of a single symbol — its incoming and outgoing calls and the processes it participates in. Additional resources expose functional clusters with cohesion scores and step-by-step process traces. Each resource is annotated with an approximate token cost, and the skill includes a checklist and a worked payment-processing example. If the index is stale it instructs the user to re-run the analyzer from the terminal.

It targets developers and AI coding agents working with the GitNexus plugin who need to onboard onto a codebase, trace flows, or locate implementation details quickly. It is read-only exploration tooling: it inspects an index and source, and does not modify code.
