SI Synthesise
Two phases:
- Interactive: Confirm project, scope, and meetings to process
- 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 runIS_DELTA — true/falsePRIOR_SYNTHESIS_PATH — path to existing cross-synthesis.md if delta run, null if first runPEOPLE_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).
