Rapid Codebase Onboarding Tour

Turns a pasted directory tree into a guided tour of an unfamiliar codebase, aimed at whoever is starting fresh or inheriting legacy code. - Identifies the architecture pattern, entry points, and the 5 most important files - Traces data flow, external dependencies, and maintenance red flags - Points to exactly which files to open first for a stated task - A follow-up step explains any single pasted file in depth: role, dependents, gotchas

Prompt
Analyze this codebase structure:

{{directory_tree}}

Tell me:
1. Architecture: What pattern is this? (MVC, microservices, monolith, etc.)
2. Entry points: Where does execution start?
3. Core modules: What are the 5 most important files/folders?
4. Data flow: How does data move through the system?
5. Dependencies: What external services/APIs does this rely on?
6. Red flags: What looks concerning from a maintenance perspective?
7. Where to start: If I need to {{specific_task}}, which files should I look at first?

Explain like I'm a senior dev who's never seen this codebase.

Then paste key files and ask:

Now explain {{file_name}} in detail:
- What does it do?
- What depends on it?
- What does it depend on?
- What are the gotchas?

Coding

Database schema design assistant

Describe a feature in plain language along with your database engine, expected scale, and existing tables to get a second opinion before writing migrations that are painful to undo. Returns proposed tables, keys, and indexes with the reasoning behind each normalization or denormalization decision, flags which constraints belong at the database level instead of application code, and stress-tests the design against one likely future change.

Git commit message writer

Takes a pasted diff plus a short note on why the change was made, and returns a commit message ready to paste into git: an imperative summary line under 72 characters, followed by an optional body covering rationale and tradeoffs. It skips line-by-line narration in favor of describing intent and impact, and flags diffs that look like they're bundling unrelated changes that should be split into separate commits.

Regex generator and explainer

Describe a matching pattern in plain language, list a few strings it must reject, and name the language or regex engine, and get back a working regular expression. It comes with a token-by-token breakdown of what each part does, a callout of edge cases it might mishandle like unicode, empty strings, or catastrophic backtracking, and three example strings that should match plus three that shouldn't.
