/session-start — Cold session start

Quick context entry. Gather state, propose focus.

Step 1: Gather context

Do NOT re-read MEMORY.md — already in system prompt via claudeMd loader.

If a workstream argument is provided — skip to Step 3.

MEM="${CLAUDE_PLUGIN_ROOT}/scripts/memory.js"
PROJ_KEY=$(pwd | tr '/.' '-' | sed 's/^-//')
MEM_DIR="$HOME/.claude/projects/-${PROJ_KEY}/memory"

# Latest handoff (global; per-workstream fetched in Step 3)
node "$MEM" --dir="$MEM_DIR" handoff

# Latest dated note
ls -t "$MEM_DIR/notes/"*.md 2>/dev/null | head -1 | xargs -I{} head -30 {}

# Workstreams sorted by aggregate weight
node "$MEM" --dir="$MEM_DIR" workstreams

# Top-3 brief inline
for WS in <top-3 from sorted list>; do
  node "$MEM" --dir="$MEM_DIR" workstream "$WS" --brief | head -15
done

Decision tree — source of focus candidates:

The workstreams table in Step 1b is always rendered in Step 4 — it's the session's map, not a fallback. The decision tree only controls where focus candidates come from.

Step 1b: Workstreams table (always rendered)

Render as table. Top-3 rows show synthesized "What's in" from --brief; rest show keywords. ➕ row is mandatory.

**Workstreams** (sorted by aggregate weight)

| # | Workstream | Last touched | What's in / Keywords |
|---|---|---|---|
| 1 | <name> | <date> | <synthesized 1-line for top-3> |
| ... | | | <keywords for rest> |
| N | ➕ Create new | | |

If user picks ➕ — ask name + keywords, then:

node "$MEM" --dir="$MEM_DIR" add-workstream <name> <keyword1> <keyword2> ...

Step 2: Git status

git status; git log --oneline -5; git branch --show-current

• Uncommitted changes → ask: "Commit or continue on top?"
• Last commit >5 days ago → note it
• Commits: synthesize last 2-3 into 1 line about the theme. Don't list verbatim.

Branch ↔ workstream check: does branch name contain any keyword from workstreams.json?

• Match → skip "Current branch" block in Step 4
• No match → run git log <branch> --oneline -10 + git diff $(git merge-base HEAD origin/main)...HEAD --stat. Synthesize phase (review iteration / new feature / hotfix). Grep notes/ for branch name. Surface in Step 4 as branch block + extra focus candidate.

If handoff has lastCommit ref: show git log <ref>..HEAD --oneline (changes since session-end).

Step 3: Workstream brief

node "$MEM" --dir="$MEM_DIR" handoff <name>      # per-workstream handoff if available
node "$MEM" --dir="$MEM_DIR" workstream <name> --brief

Show: open/done task counts, blockers, pickable now. Do NOT read full files — full context loads only after task pick in Step 4.

Step 4: Render & propose

Use the user's preferred language (from profile/language.md if present, else English). Translate labels and prose; keep markdown structure, identifiers, code refs as-is.

Required format — clean bold headers, no emoji, --- between every block, blank line after each header before content.

## Session YYYY-MM-DD

**Git:** branch `<branch>` / <N> uncommitted / last commit <days> days ago
**Commits:** <1-line synthesis>

---

**Workstreams**

[table from Step 1b]

---

**Task plan ({active workstream})**

{1-line context}
- [ ] {open task} ({SP})
- [ ] {open task} — {blocker}

---

**Current branch `{branch}`** _(only if no workstream match)_

{1-2 sentences: theme, phase, side task vs portfolio}

---

**Focus candidates**

1. **{task}** — {why now} → **{Model}** ({reason})
2. **{task}** — {why now} → **{Model}** ({reason})
3. **{task}** — {why now} → **{Model}** ({reason})

---

My hypothesis: focus on **{candidate #1}** because {reasoning grounded in handoff/git/recency}. Recommendation: **{Model}**.

Agree, pick another candidate, or **start a new workstream**?

Close with a hypothesis, not a menu. Users iterate on a proposal faster than they pick from a list. Candidates 2-3 stay visible for quick override.

MANDATORY: the closing line must keep "start a new workstream" as an explicit option. Never omit it — the hypothesis frame hides existing workstreams, so the escape hatch to create a new one has to be surfaced every time. If the user picks it, run Step 1b (workstream creation).

Model selection: Opus = planning/architecture/exploration. Sonnet = execution by plan, refactoring, review. Haiku = routine/translation/pattern copy.

Step 5: Session label

node "$MEM" --dir="$MEM_DIR" note "SESSION_START branch:$(git branch --show-current) workstream:<chosen> focus:<task>"

(Auto-routed to sessions.log, not notes.)

Rules

• Max 3 focus candidates
• Skip blocked tasks (waiting on mockups/backend) from candidates — note them separately
• Workstream argument → go straight to Step 3
• Previous session ended with compact → check via /session-restore
