Substrate fix for the intent-echo hook trap. The Mac codex install ships
~/.codex/hooks.json with intent-echo.sh on UserPromptSubmit; long prompts
containing destructive verbs or scope-limiters trigger a HIGH-STAKES
preamble that captures as the assistant message. Non-interactive `codex
exec` then produces no real output.
team-runner.sh:226 is the load-bearing dispatcher behind /swarm, /crank,
/evolve, /codex-team, /red-team — patching it once propagates the fix to
every team-runtime skill. Mirror on the dry-run echo at :195.
smoke-test-codex-skills.sh prompts contain "only" (line 175); validate
prompt contains "only" (line 61). Both trigger today.
test-sandbox-mode.sh and test-structured-output.sh patched defensively
for drift resistance.
