Shaybush /sync-context — Compound Project Context
Sync what was learned this session into the project's context files so the next session starts smarter.
Arguments: "$ARGUMENTS"
Step 1: Detect or set up context structure
Check which context directories exist at the project root:
ls docs-claude/core/ docs-claude/people/ docs-claude/projects/ 2>/dev/null
If none exist, ask the user if they want to set up the compounding-context structure. Default: create docs-claude/core/, docs-claude/people/, and docs-claude/projects/ directories. The user may want a subset (e.g., only docs-claude/core/ for a solo project without stakeholders) or different folder names to match existing project conventions — adapt accordingly.
If a subset already exists, use what's there. Don't create missing folders unless the user asks.
Once the structure exists (or has been created), proceed to Step 2.
Step 2: Read current context
Read all existing context files to understand what's already captured:
# List all context files
find docs-claude/core/ docs-claude/people/ docs-claude/projects/ -name "*.md" -type f 2>/dev/null
Read each file to understand the current state of captured knowledge.
Step 3: Review the session
Analyze this conversation for new information that should persist. Look for:
Knowledge updates (docs-claude/core/):
- Business decisions or constraints learned
- Technical decisions made
- New requirements or scope changes
- Platform, tool, or vendor evaluations
- Domain knowledge that was clarified
People updates (docs-claude/people/):
- Stakeholder preferences revealed ("she wants it simple", "he pushed back on X")
- Communication style observations
- Decisions a person made and why
- New open questions for a stakeholder
- Answers to previously open questions (close them)
Project updates (docs-claude/projects/):
- New workstreams identified → create a folder with a README.md
- Research or analysis done → save as an artifact in the relevant project folder
- Decisions made within a workstream
- Status changes or blockers
Step 4: Propose updates
Present ALL proposed changes to the user in a clear format:
## Context Updates
### docs-claude/core/business.md
- ADD: [what to add and why]
### docs-claude/people/stakeholder.md
- UPDATE preferences: [what was learned]
- CLOSE question: [question that was answered]
- ADD decision: [decision made and date]
### docs-claude/projects/platform-selection/
- CREATE: research-notes.md with [summary of what was discussed]
Group by file. Show what changes and why. Be specific — quote the conversation where relevant.
Step 5: Apply approved updates
After the user approves (they may modify or reject some), apply the changes using the Edit tool. For new files, use Write.
Rules:
- Never remove existing content unless it's clearly wrong or superseded
- Add to existing sections rather than rewriting them
- Date-stamp decisions:
- [YYYY-MM-DD] Decided to use vendor X for Phase 1 - Keep files scannable — use headers, short bullets, tables where appropriate
- If a docs-claude/people/ file has placeholder fields (like "Communication style:"), fill them in rather than adding a new section
Step 6: Commit context updates
git add docs-claude/core/ docs-claude/people/ docs-claude/projects/
git diff --cached --stat
If there are changes, commit them:
git commit -m "sync-context: update [list of files changed]"
Notes
- This skill is about persistent context, not session notes. Don't save ephemeral details (what commands were run, debugging steps tried). Save what matters for the next session.
- Bias toward updating existing files over creating new ones.
- If nothing meaningful was learned this session, say so. Don't force updates.
- Works in any project with a docs-claude/core/, docs-claude/people/, docs-claude/projects/ structure — or any subset that fits the project.
