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. python verify.py prints a code for passing test gates; self-reported checkpoints require --attest ID after the lesson questions. Each recorded checkpoint earns 10 points, a completed course badge adds 50, and the capstone earns 200.
Honest evidence. Objective checkpoints are gated by test suites; attested checkpoints are self-reported. Both are shown as self-reported evidence — never a certificate.
