Gemini for Indie SaaS (Gemini long-context)

Whole-codebase reasoning in the Indie SaaS (Gemini long-context) stack. 2M+ token context lets you paste the entire repo (or 'git ls-files | xargs cat') as part of every prompt. Best when changes span many files.

Where Gemini fits in the workflow

Dump the repo

From your terminal: `git ls-files | xargs cat > /tmp/repo.txt`. Paste that as one block into Gemini.

Prompt · Whole-repo architectural change

I'm pasting my entire repo below as one block. Each file starts with a "// path/to/file.ts" comment line.

Repo:
"""
{{paste repo dump}}
"""

The change I need:
"""
{{describe change in plain English, e.g. "swap the in-memory session store for Postgres-backed sessions, keep the public auth API stable"}}
"""

Output, in this order:
1. **Affected files** — bullet list with a 1-line "why" each.
2. **Migration order** — which files to change first so the build never breaks.
3. **Per-file diff** — unified diff for each file, in migration order.
4. **One thing I should NOT change** — even if it looks tempting in this diff.

Constraints:
- Match existing style (imports, naming, error handling).
- No new dependencies unless explicitly necessary.
- If you spot a real bug while reading the repo, mention it at the END as "Side observation", do not silently fix it.

Voice mode for debugging
Same as the recommended stack. Gemini's voice mode is fine here; the value is thinking out loud, not the LLM.
