Stage 1 got you a team, explained and corrected in plain English. Stage 2 turns that into something that actually runs — checked, not guessed, every step of the way. The result is a Python program.
This exact team, described, explained, and corrected in Stage 1. It ended with one file — a hand-off file that is a program template — with two kinds of blanks still open.
Stage 1 writes this file automatically the moment its conversation ends. Every worker's name, job description, and message shape from that conversation is already in it — but which real, registered source or sink each one maps to is still open.
registered_as=None — what's left? Match it against the registry, or register something new if nothing fits (next).
The same file also marks every worker's actual code or prompt as unapproved, until it's tested.
approved=False — what's left? Verify that this worker can be trusted, one test at a time.
The quoted phrase below is Pat's own words from Stage 1 — carried straight through into the hand-off file as this worker's description, not written by whoever does this matching step.
"Nothing fits" is a normal, common outcome here — not a failure. And
it's rarer than the built-in list alone suggests: mcp_source/mcp_sink can
already reach any server in the MCP Registry
(500+ community servers — Google Drive, Notion, Postgres, Discord, and more), so check there before
concluding it's unsupported. What's left, if truly nothing fits? Specify and register a new source or
sink — a small Python class, following an existing entry's pattern, not a redesign. See
phase3_source_sink_matching.md's "When nothing fits" for the full order of checks.
Here's the accountant, tested alone: one message in, and everything it does before answering.
This is the worker Stage 1's correction changed — it now checks current holdings first, exactly as asked. Only after a real test like this does it get approved.
The first command writes office.md and one file per worker. Then it builds, then it runs.
This isn't another isolated test — it's the whole office, actually running, start to finish.
The fee correctly grows from what the club already held each period — exactly the correction from Stage 1, now provably true, not just described.
