Create your file under: thoughts/shared/handoffs/{session-name}/YYYY-MM-DD_HH-MM_description.yaml, where:
{session-name}is from existing handoffs (e.g.,open-source-release) orgeneralif none exist
YYYY-MM-DDis today's date
HH-MMis the current time in 24-hour format (no seconds needed)
descriptionis a brief kebab-case description
Examples:
thoughts/shared/handoffs/open-source-release/2026-01-08_16-30_memory-system-fix.yaml
thoughts/shared/handoffs/general/2026-01-08_16-30_bug-investigation.yaml
2. Write YAML handoff (~400 tokens vs ~2000 for markdown)
CRITICAL: Use EXACTLY this YAML format. Do NOT deviate or use alternative field names.
The goal: and now: fields are shown in the statusline - they MUST be named exactly this.
---
session: {session-name from ledger}
date: YYYY-MM-DD
status: complete|partial|blocked
outcome: SUCCEEDED|PARTIAL_PLUS|PARTIAL_MINUS|FAILED
---
goal: {What this session accomplished - shown in statusline}
now: {What next session should do first - shown in statusline}
test: {Command to verify this work, e.g., pytest tests/test_foo.py}
done_this_session:
- task: {First completed task}
files: [{file1.py}, {file2.py}]
- task: {Second completed task}
files: [{file3.py}]
blockers: [{any blocking issues}]
questions: [{unresolved questions for next session}]
decisions:
- {decision_name}: {rationale}
findings:
- {key_finding}: {details}
worked: [{approaches that worked}]
failed: [{approaches that failed and why}]
next:
- {First next step}
- {Second next step}
files:
created: [{new files}]
modified: [{changed files}]
Field guide:
goal:+now:- REQUIRED, shown in statusline
done_this_session:- What was accomplished with file references
decisions:- Important choices and rationale
findings:- Key learnings
worked:/failed:- What to repeat vs avoid
next:- Action items for next session
DO NOT use alternative field names like session_goal , objective , focus , current , etc. The statusline parser looks for EXACTLY goal: and now: - nothing else works.
3. Mark Session Outcome (REQUIRED)
IMPORTANT: Before responding to the user, you MUST ask about the session outcome.
Use the AskUserQuestion tool with these exact options:
Question: "How did this session go?"
Options:
- SUCCEEDED: Task completed successfully
- PARTIAL_PLUS: Mostly done, minor issues remain
- PARTIAL_MINUS: Some progress, major issues remain
- FAILED: Task abandoned or blocked
After the user responds, index and mark the outcome:
# Mark the most recent handoff (works with PostgreSQL or SQLite)
# Use git root to find project, then opc/scripts/core/
PROJECT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || echo "${CLAUDE_PROJECT_DIR:-.}")
# First, index the handoff into the database
cd "$PROJECT_ROOT/opc" && uv run python scripts/core/artifact_index.py --file thoughts/shared/handoffs/{session_name}/{filename}.yaml
# Then mark the outcome
cd "$PROJECT_ROOT/opc" && uv run python scripts/core/artifact_mark.py --latest --outcome <USER_CHOICE>
IMPORTANT: Replace {session_name} and {filename} with the actual values from step 1.
These commands auto-detect the database (PostgreSQL if configured, SQLite fallback).
Note: If indexing fails, the marking step will show "Database marking was not available" - this is acceptable for the first handoff but indicates the indexing step was skipped.
4. Confirm completion
After marking the outcome, respond to the user:
Handoff created! Outcome marked as [OUTCOME].
Resume in a new session with:
/resume_handoff path/to/handoff.yaml
##. Additional Notes & Instructions
- more information, not less. This is a guideline that defines the minimum of what a handoff should be. Always feel free to include more information if necessary.
- be thorough and precise. include both top-level objectives, and lower-level details as necessary.
- avoid excessive code snippets. While a brief snippet to describe some key change is important, avoid large code blocks or diffs; do not include one unless it's necessary (e.g. pertains to an error you're debugging). Prefer using
/path/to/file.ext:linereferences that an agent can follow later when it's ready, e.g.packages/dashboard/src/app/dashboard/page.tsx:12-24
