I built TokenSafe after a $400 monthly API bill made me check what my coding agents were sending on every turn.
For a 10-line edit, the model was pulling 2,000 lines of unrelated code and lockfiles.
When other engineering teams started testing it with Cursor and Claude Code, the bill turned out to be the smaller problem. Drowned in context noise, agents forgot imports and looped on the same broken fix.
Prompt rules in .cursorrules wore off deep into a session too. Agents still tried to hardcode credential fallbacks, disable TLS checks (verify=False), pass raw SQL strings, or run git add . with .env files in the repo.
TokenSafe runs locally with Cursor, Claude Code, Codex, and Antigravity. Your coding agents read only the code each task needs and keep prompt caches intact across turns, so your team fixes fewer broken edits and keeps secrets out of git.
I'm a solo founder, and like many of you, I've had my share of frustration.The most painful one was spending money on ads, getting a decent amount of clicks, but seeing almost no conversions. It's a feeling of throwing money into a black hole.
