Capture Session

Extract everything worth persisting from the current conversation and write it to the project's LEARNINGS.md file and auto-memory. This is the session-end counterpart to /capture-learning (which captures a single item). /capture-session sweeps the entire conversation.

When to Use

• Before ending any conversation where decisions were made, context was discovered, or work was done
• When the user says "wrap up", "that's it for now", "save this", or similar
• Proactively suggest this when the session has been substantive (30+ minutes, multiple tool calls, stakeholder context discussed)

Arguments

• --dry-run — Show what would be captured without writing anything

What to Extract

Review the FULL conversation and extract items in these categories:

1. Decisions (with rationale)

Things that were decided and WHY. These prevent future sessions from re-litigating settled questions.

• Code architecture choices
• Classification rules, business logic
• What to include/exclude from scope
• Tool or approach selections

2. Action Items

Work that needs to happen but hasn't been done yet. Include owner if known.

• Bug fixes identified but not implemented
• Follow-ups with stakeholders
• Things to verify next month/sprint
• Changes to propagate to other scripts/files

3. New Context

Information discovered during the session that wasn't previously known to the project. This is the most commonly lost category.

• Stakeholder preferences, workflows, pain points
• External systems or processes mentioned
• Business rules clarified
• Constraints or requirements surfaced

4. Bugs & Issues

Problems discovered, whether fixed or not.

• What was broken and how it manifested
• Root cause (if identified)
• Fix applied (if any)
• Remaining risk or edge cases

5. Deferred Investigations

Ideas, hypotheses, or potential improvements that came up but weren't pursued. Worth revisiting later.

• Performance improvements
• Feature ideas
• Refactoring opportunities
• "What if we..." discussions

Process

Capture Session Progress:
- [ ] Step 1: Review conversation for extractable items
- [ ] Step 2: Draft extraction (present to user)
- [ ] Step 3: User confirms/edits
- [ ] Step 4: Write to LEARNINGS.md
- [ ] Step 5: Update auto-memory for cross-session items
- [ ] Step 6: Confirm

Step 1: Review Conversation

Scan the full conversation history. For each category above, identify concrete items. Be specific — include file names, line numbers, amounts, names, dates. Vague entries are useless.

Good: "Kay confirmed EXEMPT FOOD tax group should only apply to CF-produced items; 3rd party non-taxable food gets NONTAXABLE (2026-04-02 call)"

Bad: "Tax group codes need to be reviewed"

Step 2: Present Draft

Show the user what you plan to capture, organized by category:

SESSION CAPTURE — DRAFT
=======================
Session: {brief description of what was done}
Date: {today}

DECISIONS (N items)
1. {decision} — Rationale: {why}

ACTION ITEMS (N items)
1. {item} — Owner: {who} — Due: {when, if known}

NEW CONTEXT (N items)
1. {context}

BUGS & ISSUES (N items)
1. {issue} — Status: {fixed/open/deferred}

DEFERRED INVESTIGATIONS (N items)
1. {idea}

Write to LEARNINGS.md? [Y/n]

Use AskUserQuestion to confirm. If --dry-run, stop here.

Step 3: User Confirms

If user says yes (or modifies), proceed. If user removes items, respect that. If user adds items, include them.

Step 4: Write to LEARNINGS.md

File location: LEARNINGS.md is always created/updated at PROJECT_ROOT (not feature directories), since learnings apply project-wide. To determine PROJECT_ROOT: if current directory matches */features/*, go up two levels; otherwise use current directory.

If LEARNINGS.md doesn't exist, create it:

# Session Learnings

> Persistent knowledge extracted from AI coding sessions.
> Captures decisions, context, action items, and insights that should survive between sessions.
> Add entries with `/capture-session` (full sweep) or `/capture-learning` (single item).

## Decisions

## Action Items

## Context

## Bugs & Issues

## Deferred Investigations

Append entries under the appropriate section. Each entry format:

- **[YYYY-MM-DD]** {content} *(source: {conversation/stakeholder/code review/etc.})*

For action items, use checkbox format:

- [ ] **[YYYY-MM-DD]** {action item} — Owner: {who}

Step 5: Update Auto-Memory

For items that are broadly relevant across sessions (not just task-specific), also write to auto-memory:

• New Context about stakeholders, external systems, or business rules → type: project or type: user memory
• Decisions that affect how future sessions should behave → type: feedback memory
• Don't duplicate — check existing memory files first

Skip this step if the project doesn't use auto-memory (no .claude/projects/ memory directory).

Step 6: Confirm

SESSION CAPTURED
================
Written to LEARNINGS.md:
  - {N} decisions
  - {N} action items
  - {N} context items
  - {N} bugs/issues
  - {N} deferred investigations

{If auto-memory updated}
Auto-memory updated:
  - {list of memory files created/updated}
{/If}

This context will be available in future sessions.

CLAUDE.md Integration

For the skill to be effective, the project's CLAUDE.md should include:

@LEARNINGS.md

This ensures future sessions load the learnings at startup. If CLAUDE.md exists but doesn't reference LEARNINGS.md, suggest adding it.

Guidance for Extraction Quality

Include if:

• It would save a future session from re-discovering something (> 5 min saved)
• A stakeholder said it (their words carry weight)
• It contradicts a prior assumption
• It affects multiple files or future work
• Someone would ask "why did we do it this way?"

Exclude if:

• It's obvious from reading the code or git log
• It's a temporary debugging step that's already resolved
• It's general programming knowledge
• It's already captured in CLAUDE.md, PROJECT_STATUS.md, or existing memory

Convert relative dates: "next month" → "May 2026", "Thursday" → "2026-04-03"

Error Handling

Situation	Action
No substantive items found	Report "Nothing to capture — session was exploratory or all items are already documented"
LEARNINGS.md is very large (>200 lines)	Warn user, suggest archiving older entries to LEARNINGS_ARCHIVE.md
No auto-memory directory	Skip Step 5, note in output
User cancels	Stop gracefully, no writes
