disinto/predictor/predictor-run.sh

#!/usr/bin/env bash
# =============================================================================
# predictor-run.sh — Cron wrapper: predictor execution via SDK + formula
#
# Synchronous bash loop using claude -p (one-shot invocation).
# No tmux sessions, no phase files — the bash script IS the state machine.
#
# Flow:
#   1. Guards: cron lock, memory check
#   2. Load formula (formulas/run-predictor.toml)
#   3. Context: AGENTS.md, ops:RESOURCES.md, VISION.md, structural graph
#   4. agent_run(worktree, prompt) → Claude analyzes, writes to ops repo
#
# Usage:
#   predictor-run.sh [projects/disinto.toml]   # project config (default: disinto)
#
# Cron: 0 6 * * * cd /path/to/dark-factory && bash predictor/predictor-run.sh

PROMPT="You are the prediction agent (goblin) for ${FORGE_REPO}. Work through the formula below.

Your role: abstract adversary. Find the project's biggest weakness, challenge
planner claims, and generate evidence. Explore when uncertain (file a prediction),
exploit when confident (file a prediction AND dispatch a formula via an action issue).

Your prediction history IS your memory — review it to decide where to focus.
The planner (adult) will triage every prediction before acting.
You MUST NOT emit feature work or implementation issues — only predictions
challenging claims, exposing gaps, and surfacing risks.
Use WebSearch for external signal scanning — be targeted (project dependencies
and tools only, not general news). Limit to 3 web searches per run.
