About — Codebase Context Skill

The Problem

AI coding assistants like Claude Code are powerful, but they waste significant tokens exploring your codebase from scratch on every query. They read files they don't need, lose context when the window fills up, and have no memory of what they've already done in the session.

The result: higher costs, slower responses, and less accurate outputs — especially on complex tasks that touch multiple files.

The Solution

codebase-context-skill is a context engineering middleware that sits between your queries and Claude Code. It indexes your codebase once, then ensures every subsequent query gets exactly the right context — no more, no less.

It works like how engineering teams actually operate: understand the architecture first, scope the change, track what was touched, and verify the results. All of this happens locally via markdown files that persist across the session.

How It Works

Index once — Deep-scan your codebase on init, generating a project map, architecture doc, file rankings, and conventions
Query smart — Hybrid index lookup + live Glob/Grep scan selects only relevant files per query
Track everything — Every action logged as a git-commit-style entry so context persists without API calls
Right model, right task — Haiku for scanning, Sonnet for coding, Opus for deep reasoning

Key Principles

Never explore unnecessarily — Index first, read only what matters
Local tools first — Glob + Grep + Read before any API calls
Everything persists locally — MD files maintain context across the session
Token guardrails — Smaller models for scanning, bigger models for thinking
Commit-style tracking — Every change logged like a git commit locally

What's Included

14 slash commands — Context management, workflow, testing, auditing, research, deployment
3 specialized agents — Context builder, test runner, code auditor
Hybrid file selection — Pre-built index + live scanning for optimal accuracy
Session tracking — Full commit-style task log that persists across interactions
Web research — Official docs lookup, error resolution, dependency health checks
