Sach1ng Knowledge Updater
Update knowledge layer documents (knowledge/) with automatic snapshotting. Before any update, the current version is saved to memory/knowledge-snapshots/ so the retrospective agent can track how strategy evolved over time.
When to Use
- Updating
knowledge/files (strategy, segments, metrics, competitive landscape) - After quarterly planning when strategy shifts
- After significant market or competitive changes
- When asked "update my strategy", "refresh knowledge docs", or "knowledge update"
Process
1. Identify What's Changing
Ask if not clear:
- Which knowledge doc(s) are being updated?
- What changed? (new strategy, updated segments, revised metrics, competitive shift)
- Why? (quarterly planning, market shift, exec direction, experiment results)
2. Snapshot Current State
Before making any changes, save the current version:
- Create a timestamped snapshot directory:
memory/knowledge-snapshots/YYYY-MM-DD/ - Copy the file(s) being updated into that directory with their original names
- Add a
_changelog.mdfile to the snapshot:
# Knowledge Snapshot — YYYY-MM-DD
**Reason for update:** [what triggered this change]
**Files updated:** [list]
## Changes Summary
- [File 1]: [what changed and why]
- [File 2]: [what changed and why]
3. Make the Update
Edit the knowledge file(s) in knowledge/{product}/ with the new content. Ensure:
- Format matches the existing template structure
- Changes are clearly reflected in the content
- No orphaned references (e.g., removing a segment that's referenced elsewhere)
4. Log as a Decision (optional)
If the knowledge update reflects a significant strategic shift, suggest logging it as a decision trace using the decision-logger skill.
Output
- Updated knowledge file(s) in
knowledge/{product}/ - Snapshot of previous version in
memory/knowledge-snapshots/YYYY-MM-DD/ - Changelog documenting what changed and why
Over time, snapshots enable:
- Drift detection: How has stated strategy evolved quarter over quarter?
- Decision coherence: Do knowledge updates align with decision traces?
- Retrospective analysis: The retrospective agent compares current knowledge to snapshots to surface gradual shifts
