Note Taking

Maintain posts/{post}/discussion.md — an audit trail of decisions, Claude's contributions, and outcomes. Two audiences: Claude (quick context to avoid repetition across sessions) and the user (trace why any decision was made).

Note: The SessionEnd hook at .claude/hooks/session-wrap.sh auto-appends a session entry and commits when a session closes with uncommitted posts/ changes. Invoke this skill explicitly when a major decision is made mid-session and you want it captured in the AUDIT TRAIL (not just the session log) — or when the user asks.

Core principle

Attribute clearly: what Claude did → what user decided → why → what happened. A session entry without attribution is narrative filler.

File structure

# Discussion Notes: [Project Name]

## AUDIT TRAIL: Key Decision Points
[Decisions with attribution — added as they happen]

## WHAT CLAUDE DID (Contributions)
### Research / Writing / Quality Control / Technical
[Bullet lists, updated on milestones]

## WHAT WORKED / DIDN'T WORK
### Worked Well ✅
| What Claude Did | User Decision | Outcome |
### Didn't Work ❌
| What Claude Did | Problem | Lesson |

## SESSIONS (Chronological Detail)
[Session-by-session entries — appended; oldest stays at top]

Before writing

Read the existing discussion.md first. Extract decisions already made (don't re-debate), coverage (don't repeat), and failures (don't retry).

Session entry template

Append at the bottom of the SESSIONS section:

## Session N: [Short Title] (YYYY-MM-DD)

### Context
[Why this session happened — 1–2 sentences]

### What Claude Did
- Research: [what]
- Analysis: [what]
- Writing: [what drafted/revised]
- Tools: [scripts/automation]

### User Decisions
- [What was decided and why]

### Outcomes
- ✅ Worked: [successes]
- ❌ Didn't: [failures]
- Files modified: [list]

### Next Steps
[What comes next]

Keep under ~40 lines. Terse beats thorough — the audit trail is the load-bearing record.

One entry per session. If a session runs long, update its entry rather than appending (cont. N) sub-entries — eight individually-compliant sub-entries once made a 369-line file. When SESSIONS passes ~250 lines, compress everything older than the last three sessions into the AUDIT TRAIL and WHAT WORKED/DIDN'T tables, which is what those sections are for.

discussion.md is public

posts/ ships to a public GitHub repo, and published posts link back to their folders. Everything written here is published, including working notes. Never record: names the user has not agreed to publish, private message content from third parties, or anything framed as "don't put this in the post." Adding a name later is one edit; removing it from git history is not.

Decision entry template

Use for significant decisions only (framing, scope, major revisions). Add to the AUDIT TRAIL section at the top:

### Decision: [Title] (YYYY-MM-DD, Session N)

**Claude's Analysis:**
- [Research/analysis performed; options presented]

**Claude's Recommendation:**
[What Claude suggested and why]

**User Decision:**
[What the user actually decided — may differ from recommendation]

**Rationale:**
[Why the user made this choice]

**Outcome:**
✅/❌ [What happened as a result]

If Claude had no recommendation (presented options equally), state that explicitly. Do not invent one.

When to invoke this skill explicitly

The SessionEnd hook handles routine session logging. Use /note-taking for:

• Major decisions that need to land in AUDIT TRAIL (not just SESSIONS)
• Series milestones (a part published, direction pivot)
• When discussion.md doesn't exist yet and you're creating it from scratch
• When the user asks

Don't use this skill to re-record what the hook already committed. Check git log -- posts/{post}/discussion.md first.

For series work

Add these sections when working on Part N of a series:

## WHAT'S BEEN COVERED
### Part 1 established: [bullets]
### Part 2 established: [bullets]

## SERIES STATE
- Part 1: PUBLISHED (date)
- Part 2: DRAFT
- Part 3: KIV

## SERIES LESSONS
- ✅ [What worked across parts]
- ❌ [What to avoid repeating]

Good vs. bad

Good: "Decision: use '150+ hours' (Session 2). Claude found 79 commits across 36 days → revised from 600 to 150. User approved. Outcome: ✅ more credible."

Bad: "We decided to use 150 hours instead of 600." (Missing: what Claude did, why, what happened.)
