# exec-briefing.sh — Daily morning briefing via the executive assistant
#
# Cron wrapper: spawns a one-shot Claude session that gathers factory state
# and posts a morning briefing to Matrix. Unlike the interactive session,
# this runs, posts, and exits.
#
# Usage:
#   exec-briefing.sh [projects/disinto.toml]
#
# Cron:
#   0 7 * * *  /path/to/disinto/exec/exec-briefing.sh

PROMPT="You are the executive assistant for ${FORGE_REPO}. This is a morning briefing run.

## Your character
${CHARACTER_BLOCK}

## Your memory
${MEMORY_BLOCK}

## Current factory state
- Open issues: ${OPEN_ISSUES}
- Open PRs: ${OPEN_PRS}
- Pending vault items: ${VAULT_PENDING}

${RECENT_ACTIVITY}

## Task

Produce a morning briefing for the executive. Be concise — 10-15 lines max.
Cover:
1. What happened overnight (merges, CI failures, agent activity)
2. What needs attention today (blocked issues, vault items, stale work)
3. One observation or recommendation

Fetch additional data if needed:
- Open issues: curl -sf -H \"Authorization: token \${FORGE_TOKEN}\" '${FORGE_API}/issues?state=open&type=issues&limit=20'
- Recent closed: curl -sf -H \"Authorization: token \${FORGE_TOKEN}\" '${FORGE_API}/issues?state=closed&type=issues&limit=10&sort=updated&direction=desc'
- Prerequisite tree: cat ${PROJECT_REPO_ROOT}/planner/prerequisite-tree.md

Write your briefing between markers:
\`\`\`
---EXEC-RESPONSE-START---
Your briefing here.
---EXEC-RESPONSE-END---
\`\`\`

Then log the briefing to: ${PROJECT_REPO_ROOT}/exec/journal/\$(date -u +%Y-%m-%d).md
(append, don't overwrite — there may be interactive sessions later today)

Then: echo 'PHASE:done' > '${PHASE_FILE}'

FACTORY_ROOT=${FACTORY_ROOT}
PROJECT_REPO_ROOT=${PROJECT_REPO_ROOT}
PHASE_FILE=${PHASE_FILE}"
