SI Synthesise

Two phases:

1. Interactive: Confirm project, scope, and meetings to process
2. Background: Full analysis → cross-synthesis.md → per-person standing brief updates

---

Phase 1 — Confirm Scope

Step 1 — Print:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  CROSS-SYNTHESISE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Step 2 — Project. Read [workspace-root]/.current-session to identify the active project (parse left of / if portfolio). Look up the folder path in projects.md. Show the project name. Confirm with user (Y/N or just Enter).

Step 3 — Check for prior synthesis. Look for [PROJECT_ROOT]/intelligence/cross-synthesis.md.

• Found: Read its frontmatter. Extract last-synthesised. Show: Last synthesis: [date]. Running in delta mode — only new meetings will be re-read; prior synthesis used as baseline.
• Not found: Show: No prior synthesis found. First run — all meetings will be processed.

Step 4 — Scope meetings. Glob all subdirectories under [PROJECT_ROOT]/intelligence/meetings/. For each, check for a synthesis.md and read only its frontmatter (first 20 lines) to get the date field.

• Delta mode: Include only synthesis files with date newer than last-synthesised.
• First run: Include all synthesis files found.

Display:

Meetings to process:
  [YYYY-MM-DD]  [topic from frontmatter]
  ...
  [N] meeting(s)

If delta run, also show: [M] prior meeting(s) carried forward from last synthesis — will not be re-read.

If delta mode and no new meetings found: say No new meetings since last synthesis ([date]). Nothing to do. and stop.

Step 5 — Confirm. Ask: Run synthesis? (Y/N). Wait for response.

Step 6 — Hand off.

Say: Got it. Running cross-synthesis in the background — you can keep working.

Spawn background agent (run_in_background: true). Pass:

• PROJECT_ROOT — e.g. projects/acme-corp-launch/
• MEETINGS_DIR — [PROJECT_ROOT]/intelligence/meetings/
• NEW_MEETING_FILES — list of full paths to synthesis.md files to process this run
• IS_DELTA — true/false
• PRIOR_SYNTHESIS_PATH — path to existing cross-synthesis.md if delta run, null if first run
• PEOPLE_DIR — root-level people/ directory path (e.g. people/)
• OUTPUT_PATH — [PROJECT_ROOT]/intelligence/cross-synthesis.md

Tell the agent: Read .claude/skills/ctx-synthesise/BACKGROUND.md for full instructions. Do not ask questions — proceed through all steps. After writing cross-synthesis.md, also update the Stakeholder Dynamics section of [PROJECT_ROOT]/context/current-state.md if it exists. Use the cross-synthesis findings to populate: Current read (2-3 sentences), Key positions, Tensions, Who to watch. Update the section's _Last updated:_ line and the file frontmatter (last-updated, updated-by: ctx-synthesise).
