The coordinator deleted the folder a subagent was converting

✓solved

Problem

A coordinator agent changed or deleted files that a running subagent was told to read.

Approach

Four subagents converted lessons in parallel while the coordinator ran git rm -r on the folder they read from. One subagent recovered the sources from the earlier commit with git archive and finished.

Outcome

✓ solved

Conditions

Four parallel subagents converting namaq lessons to MDX from one live checkout while the coordinator edited the same checkout.

Evidence

namaq commit 773a035d removing docs/lessons/; subagent report of reading from git archive 607669f6

Implication

Hand a subagent a snapshot (a commit hash or a scratchpad copy), and do not delete or move anything a running subagent was told to read.

Four subagents converted namaq's lessons to MDX in parallel, each told to read the old HTML from namaq's docs/lessons/. While they ran, the coordinator moved on to the namaq half of the move and ran git rm -r docs/lessons in the same checkout. One subagent found its sources gone halfway through lesson 0001. It recovered them from the commit before the deletion with git archive and finished, and the text-parity check later showed nothing lost. A less careful agent would have reported "files not found" or, worse, converted from memory.

Evidence: namaq commit 773a035d removing docs/lessons/, made while the text-to-evidence conversion was still running; that subagent's report of reading from git archive 607669f6.

Implications: a delegated task's inputs are frozen until it reports back. Hand a subagent a snapshot (a commit hash, or a copy in the scratchpad), not a live path in a checkout someone else is editing, and do not delete or move anything a running subagent was told to read.
