Session Documentation

Complements beads (task-level tracking) and skills (pattern-level knowledge) with session-level context - capturing decisions, rationale, and user thoughts that connect individual tasks.

Philosophy

• Beads tasks track what was done
• Skills capture how to do recurring things
• Session docs capture why decisions were made and user intent

Don't duplicate - reference beads task IDs, create issues for actionable items.

Session Storage

Sessions are stored in .beads/sessions.jsonl with this structure:

{
  "id": "session-<short-id>",
  "date": "2025-12-30",
  "title": "Brief descriptive title",
  "summary": "1-2 sentence overview",
  "decisions": [
    {
      "topic": "What was decided",
      "choice": "The decision made",
      "rationale": "Why this over alternatives",
      "alternatives_considered": ["alt1", "alt2"]
    }
  ],
  "user_thoughts": "Captured user intent, preferences, or ideas expressed during session",
  "problems_encountered": ["Problem 1 and how it was resolved"],
  "related_tasks": ["kapan-xxx", "kapan-yyy"],
  "created_issues": ["kapan-zzz"]
}

Writing Good Close Reasons

When closing beads tasks, write close reasons that capture rationale, not just actions:

Weak Close Reasons

• "Done"
• "Fixed the bug"
• "Created the component"

Strong Close Reasons

• "Fixed by adding null check - root cause was async race condition where user data loaded before auth completed"
• "Created StickySection component using Intersection Observer for performance over scroll listeners"
• "Kept hooks separate - they serve different purposes (swap tx data vs quote-only) despite similar names"

Pattern: [What was done] - [why this approach / what was learned]

When to Write Session Summaries

Write a session summary when:

• Significant planning discussion occurred (like architecture decisions)
• Multiple related tasks were completed as part of a larger effort
• User expressed preferences/intent worth preserving
• Problems were solved in non-obvious ways

Don't write summaries for:

• Quick single-task sessions (the beads task itself is enough)
• Sessions that only involved exploration/reading

Capturing User Planning Discussions

When the user is thinking through a problem or making decisions:

1. Listen for expressed preferences - "I want...", "I prefer...", "Let's do X over Y"
2. Note the rationale they give - even partial reasoning is valuable
3. Extract actionable items - create beads issues for concrete next steps
4. Summarize their thought process - helps future sessions understand intent

Example Flow

User says: "I'm thinking we should store this in beads rather than a separate folder - keeps things together, and we already have the tooling. Though I'm not sure about the schema yet."

Capture as:

{
  "decisions": [{
    "topic": "Session docs storage location",
    "choice": ".beads/sessions.jsonl",
    "rationale": "Consolidates tooling, avoids separate system",
    "alternatives_considered": ["docs/devlog/", "extend interactions.jsonl"]
  }],
  "user_thoughts": "User prefers consolidation over separation. Schema details still open."
}

If there's a concrete next step, create a beads issue.

Template: Writing a Session Summary

# 1. Review what happened
beads list  # see tasks touched this session

# 2. Write the session entry (append to sessions.jsonl)
# Include: decisions made, user intent captured, any new issues created

# 3. Link back - mention session ID in related task close_reasons if helpful

Don't Over-Document

• Keep summaries brief (aim for <200 words)
• Skip sessions that don't have meaningful decisions
• One session = one entry (don't split or combine artificially)
• Reference beads tasks instead of re-describing work
