Python developer toolchain with agents

Ship like an engineer: a real pytest suite that catches seeded bugs, a packaged CLI, and a verified web API — built with your agent, proven by verify.py.

TL;DR

Who it is forLearners who finished the free foundation path and want real engineering skills.
What you finish withYou can write a test suite that actually catches bugs, package and release a CLI, and ship a verified API endpoint — the toolchain every Python project needs.
The badgeToolchain Builder — every required module claimed; a fork counts once you finish either side. Self-reported evidence, never a certificate.

The map

From start to badge

Follow the rail down. A fork is a pick-one choice — your agent, your call; both sides stay claimable as bonus practice.

    Badge: Toolchain Builder

    Every required module claimed, capstone included — a fork needs either side, not both. Self-reported evidence, not a certificate.

Evidence

Points come from recorded claim codes

Checkpoint claims. Each course checkpoint prints a deterministic claim code via python verify.py progress — 10 points per checkpoint, +50 per completed course badge, 200 for the capstone.

Honest evidence. Objective checkpoints are gated by test suites; attested checkpoints are self-reported. Both are shown as self-reported evidence — never a certificate.
