From b24b86723b21ba02b3d09f9a138841b47d33edcc Mon Sep 17 00:00:00 2001 From: Greg Gauthier Date: Sat, 28 Mar 2026 12:36:06 +0000 Subject: [PATCH] feat(analyze): implement educational project analysis with language prompts - Add Go-specific analysis prompt in .grokkit/prompts/go.md - Expand cmd/analyze.go to discover files, detect language, load prompts, build context, generate report via Grok, and handle output with preview/confirmation - Integrate analyzeCmd into root command - Introduce internal/linter/language.go for primary language detection - Add internal/prompts/analyze.go for loading analysis prompts from project or global locations --- .grokkit/prompts/go.md | 31 ++++++ cmd/analyze.go | 189 +++++++++++++++++++++++++++++++++--- cmd/root.go | 1 + internal/linter/language.go | 4 + internal/prompts/analyze.go | 32 ++++++ 5 files changed, 241 insertions(+), 16 deletions(-) create mode 100644 .grokkit/prompts/go.md create mode 100644 internal/linter/language.go create mode 100644 internal/prompts/analyze.go diff --git a/.grokkit/prompts/go.md b/.grokkit/prompts/go.md new file mode 100644 index 0000000..f9f30a7 --- /dev/null +++ b/.grokkit/prompts/go.md @@ -0,0 +1,31 @@ +You are an expert Go educator and code archaeologist. +Analyze this Go project for a developer or hobbyist who wants to deeply understand the codebase. + +Produce a single, well-structured Markdown report with these exact sections: + +# Project Analysis: {{Project Name}} + +## Tech Stack & Layout +- Primary language, version, build tools +- Key dependencies and why they were chosen +- Directory structure overview + +## Module / Package Relationships +- How packages depend on each other (import graph) +- Public APIs and their purpose + +## Function & Method Reference +For every exported function/method: +- What it does (clear English) +- How it works (key logic, patterns) +- Why it exists (design rationale) + +## Object & Data Flow +- Major structs/types and their relationships +- Any database/ORM mappings if present + +## Learning Path & Gotchas +- Recommended reading order +- Common pitfalls for newcomers + +Be educational, encouraging, and precise.
