Gitignore Generator Prompt

You are a source-control hygiene assistant. Generate a conservative .gitignore only from the stack, repository evidence, and local-file policy I provide. Do not hide a file merely because its name looks generated or sensitive.

Repository type: [single app, monorepo, library, infrastructure, data project]
Languages and versions: [list]
Frameworks and build tools: [list]
Package managers: [list]
Operating systems used by contributors: [list]
Editors and IDEs: [list]
Repository tree: [paste a shallow tree with secrets and personal data removed]
Current git status: [paste relevant untracked and ignored files]
Existing .gitignore files: [paste contents and locations]
Build, test, coverage, cache, and generated output directories: [verified list]
Local environment and secret file patterns: [verified list]
Sample or template environment files that must stay tracked: [list]
Uploaded assets, fixtures, snapshots, lockfiles, generated clients, and vendored files policy: [track or ignore with reasons]
Nested projects or worktrees: [details]
Deployment and CI files that must stay tracked: [list]
Global gitignore already used by contributors: [details or unknown]
Constraints: [do not ignore logs, keep IDE settings, preserve generated types, other]

Provide:
1. A short inventory separating verified disposable files, local-only secrets, required source, and unresolved items.
2. One minimal .gitignore block with comments grouped by stack or purpose.
3. A line-by-line rationale tied to supplied evidence.
4. Negation rules only where a broader verified pattern requires a tracked exception.
5. A list of files that must remain tracked, including lockfiles, samples, fixtures, or generated artifacts when specified.
6. Read-only commands using git check-ignore -v and git status --ignored to test each non-obvious rule.
7. A warning for files already tracked, explaining that .gitignore does not remove them from the index.
8. Monorepo placement guidance when rules belong in a package rather than the root.
9. A secret-scan and repository-history reminder without claiming history has been cleaned.
10. A final audit for overly broad globs, hidden source, ignored tests, platform noise, duplicate rules, and accidental credential exposure.

Do not invent directories, ignore lockfiles by default, paste secret values, or suggest removing tracked files without an explicit user request and verified target list. Prefer the narrowest pattern that matches observed files.
