- 00-kanban.md rebuilt: ▶ NEXT PLAN pointer (iteration 4 — emitter, corpus, `woc build`) then six buckets — stories, in progress, done, pending, discarded, learnings. It tracked only the Rust runtime before, so the whole OOP track (wovm shipped, woc Tasks 1-8 shipped) was invisible. - Board now records iteration 3's known gaps instead of silently owing them: `?T` plumbed but unenforced; E205/E201/E203/E204 dead, so structural interface satisfaction is unchecked. - New discarded.md — settled rejections with reasons so they are not re-proposed: inheritance, `abstract` newtypes, Money/SKU/Float, Dynamic/cast/ macro/extern, AOT-to-C, Menhir, shared engine state, external deployer. - RECOVERED docs/plan/exploration/blue-green-vm/00-vision.md — gone from disk, never committed (gitignored path), cited by five docs incl. principle 12. - Root cause was broader: all seven forward-roadmap plans in docs/superpowers/plans/ were untracked and ignored, on one disk only. Rules were half-fiction — 33 of 34 exploration files were already tracked, so they swallowed only *new* files. - Dropped the docs ignore rules (exploration, oop-vm, superpowers/plans, examples/agent-loop, examples/mcp-think) with a do-not-re-add comment; added __pycache__/*.pyc. `tests/` stays ignored but warns that the next plan lands the corpus there.

"""Smoke-test the agent loop without any model.
|
|
|
|
Stands up a canned OpenAI-compatible /chat/completions endpoint on a local
|
|
port and drives agent.run_turn() through a scripted conversation:
|
|
|
|
round 1: the "model" calls read_file on notes.txt -> executed for real
|
|
round 2: it sends a tool call with broken JSON args -> fed back as an error, not a crash
|
|
round 3: it returns a final answer
|
|
|
|
This verifies the three load-bearing behaviours of the loop: tool execution
|
|
with result feedback, errors-as-results self-correction, and termination on
|
|
a plain (tool-call-free) answer.
|
|
|
|
Usage: python3 test_loop.py # standard library only, no model needed
|
