About

Email triage system that handles both one-time setup and recurring triage in a single skill. Auto-detects state: if no knowledge base exists at ${WORKSPACE}/Email/, runs an 8-section onboarding interview (grill-me discipline, one question at a time) to build a 7-file personalized KB, then offers to run triage immediately. If the KB already exists, skips setup and goes straight to triage — searches recent emails, classifies them via the user's taxonomy, researches new senders, generates TAKE IT/WORTH/PASS/FLAG recommendations, drafts replies (NEVER sends), delivers a report, and updates the KB. Use with 'update' argument to refresh preferences. Setup triggers: 'set up my inbox', 'configure inbox triage', 'set up my email system', 'configure email triage', 'build my email knowledge base', 'initialize email management'. Triage triggers: 'triage my inbox', 'inbox triage', 'check my email', 'run email triage', 'process my inbox', 'what's new in my email', 'handle my email', 'email triage'.

# Inbox — Email Triage System

Self-contained email triage skill. Handles setup and recurring triage in a single command. Detects its own state and routes accordingly — no need to remember which mode to run.

## State Detection (Always First)

Before anything else, check for the KB:

| State | Route |
|---|---|
| Argument is `update` | → **Update Mode** |
| `${WORKSPACE}/Email/email-taxonomy.md` does NOT exist | → **Setup Mode** |
| `${WORKSPACE}/Email/email-taxonomy.md` exists | → **Triage Mode** |

**Edge cases:**
- User says "set up my inbox" but KB exists → acknowledge, ask: "run triage / update preferences / both?"
- User says "triage my inbox" but no KB → "No knowledge base found. Running setup first, then triage immediately after." → Setup → Triage
- Partial KB (some files missing) → list which files are missing, ask: "run full setup / fill in only the missing sections?"

---

## SETUP MODE — Build the Knowledge Base

Runs when no KB exists.

### Conduct Discipline

**Do NOT generate all files at once.** Walk through the 8 sections one at a time. Each section commits its file(s) before moving on. Partial completion (user drops off mid-interview) still produces a usable partial KB.

- **One question per turn.** Never bundle — even across section boundaries.
- **"Why I'm asking" on every question** — users answer better when they know what's at stake.
- **Forcing format where possible.** Multi-choice > open-ended.
- **Dependency-ordered.** Section N informs Section N+1.

See `references/grill_me_section_walk.md` for the 8-section discipline detail.

### Knowledge Base — 7 Files to Produce

Write to `${WORKSPACE}/Email/`:

| File | Purpose | Required? |
|---|---|---|
| `email-taxonomy.md` | Classification system + report preferences | **Yes** |
| `email-patterns.md` | Reply voice, tone, templates, hard rules | **Yes** |
| `evaluation-framework.md` | Decision tree for opportunity emails | Only if user receives pitches/opportunities |
| `rate-card.md` | Pricing, terms, negotiation posture | Only if user has pricing |
| `blocklist.md` | Auto-skip senders + learned decline patterns | **Yes** (seeded, grows over time) |
| `tracker.md` | Active follow-ups, overdue items, deadlines | **Yes** (starts mostly empty) |
| `triage-log/` | Directory for per-run logs | **Yes** (created empty) |

### Stop Condition

~25–31 questions total across 8 sections. Hard ceiling: 35 questions including sub-clarifications. Section 4 (Evaluation Framework) is skipped entirely when Section 1 surfaced no opportunity-email category. After Section 8's confirmation + handoff message, intake is closed — to change preferences, use `update` mode.

### Section 1: The Big Picture

Six grill-me questions, one at a time:

- **S1.Q1:** "What do you do? Give me your role and business in 1–2 sentences. *Why I'm asking:* Context shapes what email patterns to expect — a solo creator's inbox looks nothing like an enterprise PM's."
- **S1.Q2:** "What dominates your inbox? Pick the top 1–2: sales pitches / client work / internal team / newsletters / customer support / financial / other. *Why I'm asking:* Dominant categories drive the taxonomy."
- **S1.Q3:** "Rough volume split — e.g., '60% business inquiries, 20% ops, 20% noise'. *Why I'm asking:* The split tells me where to focus triage effort."
- **S1.Q4:** "Which email address(es) should triage cover? *Why I'm asking:* If multiple, I'll set up per-address taxonomies."
- **S1.Q5:** "Run frequency: once daily / 2x daily / 3x daily / on-demand only? *Why I'm asking:* Drives the default search window in triage (9h overlap for 2x/day)."
- **S1.Q6:** "Anyone helping manage email — assistant, VA, team — or solo? *Why I'm asking:* Persona handling differs for delegated inboxes."

**Action:** Build mental model. Do NOT write files yet. Note whether opportunity emails are a category (drives S4 skip-logic).

### Section 2: Email Categories

Propose 5–7 categories based on Section 1 — pre-recommend a subset:

- New Opportunities
- Active Conversations
- Action Required
- Financial
- Important/Personal
- Informational
- Ignore/Low Priority

Three forcing questions, one at a time:

- **S2.Q1:** "Here's my proposed taxonomy: [list]. Does this match your inbox reality — yes / mostly / no? *Why I'm asking:* If 'no', I need to redo the taxonomy before any other section makes sense."
- **S2.Q2:** "Missing categories? List them. (Skip if none.) *Why I'm asking:* Missing categories produce uncategorized emails downstream, which hurts triage quality."
- **S2.Q3:** "Which category takes the MOST time per email? *Why I'm asking:* That's where draft-reply effort needs to focus most."

**Action:** Generate `email-taxonomy.md` with categories, signals, and default actions per category.

### Section 3: Reply Style & Voice

Six grill-me questions plus the critical sample request:

- **S3.Q1:** "Register: formal / casual / in-between? *Why I'm asking:* Calibrates default voice; we'll refine from samples next."
- **S3.Q2:** "Three communication pet peeves — phrases you hate, openings you avoid. *Why I'm asking:* I treat these as forbidden tokens in drafts."
- **S3.Q3:** "Phrases or sign-offs you always use — list as many as come to mind. *Why I'm asking:* These are your voice fingerprints."
- **S3.Q4:** "Different persona for different contexts — e.g., assistant replies as you? *Why I'm asking:* Persona context changes pronoun + signature handling."
- **S3.Q5:** "Typical reply length — one-liner / short paragraph / longer? *Why I'm asking:* Length is the easiest voice signal to get wrong."
- **S3.Q6:** "Hard rules — never X / always Y? *Why I'm asking:* Hard rules are enforced as non-negotiable in every draft."

**S3.SAMPLES (highest-quality input):**

> **Paste 3–5 real sent emails from your inbox.**
>
> *Why I'm asking:* Self-description of voice is unreliable. Real samples are the best signal — use `scripts/voice_sample_analyzer.py` to extract patterns.

**Action:** Generate `email-patterns.md`. See `references/voice_calibration.md` for the sample-extraction discipline.

### Section 4: Evaluation Framework (Conditional)

**Skip if Section 1 surfaced no opportunity emails.** Otherwise six grill-me questions:

- **S4.Q1:** "First thing you check when pitched something — give me your gut filter. *Why I'm asking:* That's the top of the decision tree."
- **S4.Q2:** "Three instant deal-breakers. *Why I'm asking:* These become PASS-auto signals."
- **S4.Q3:** "Three things that make you immediately interested. *Why I'm asking:* These become TAKE-IT signals."
- **S4.Q4:** "Standard pricing / terms — or 'no fixed pricing'? *Why I'm asking:* If you have a rate card, I'll generate one."
- **S4.Q5:** "Negotiation posture: firm / flexible / depends on context? *Why I'm asking:* Drives draft tone on counter-offers."
- **S4.Q6:** "VIP senders or organizations that always get engagement. *Why I'm asking:* VIP list bypasses normal PASS filters."

**Action:** Generate `evaluation-framework.md` + `rate-card.md` (if pricing exists).
