| description | 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).
Section 5: Blocklist & Patterns
- S5.Q1: "Senders or domains to always skip. (Skip if none.) Why I'm asking: Auto-blocklist saves the most time per run."
- S5.Q2: "Patterns in emails you always delete. Why I'm asking: Patterns let triage auto-skip variants without exact-match maintenance."
- S5.Q3: "Specific companies / recruiters / newsletters wasting time. Why I'm asking: These seed the blocklist; triage will add more as you override decisions."
Action: Generate blocklist.md.
Section 6: Current State
- S6.Q1: "Active threads you're tracking — list with one-line context each. (Skip if none.) Why I'm asking: These become tracker entries so triage knows existing context."
- S6.Q2: "Overdue replies? Why I'm asking: Triage flags these as priority every run until resolved."
- S6.Q3: "Time-sensitive items with deadlines? Why I'm asking: Tracker enforces deadlines and surfaces them as overdue at the right time."
Action: Generate tracker.md + create empty triage-log/ directory.
Section 7: Report Preferences
- S7.Q1: "Delivery format: email draft to self / file in workspace / chat summary only. Why I'm asking: The triage report goes here every run."
- S7.Q2: "Detail level: 30-second scan / detailed breakdown / both. Why I'm asking: Affects report length."
- S7.Q3: "Anything always shown first — e.g., overdue payments, VIP messages? Why I'm asking: Custom top-of-report rules surface what you care about above standard sections."
Action: Append report preferences to email-taxonomy.md.
Section 8: Confirmation & Handoff
List every file created with a one-sentence summary. Run scripts/kb_validator.py --workspace ${WORKSPACE} to confirm the 7-file contract is satisfied.
Then ask:
Your triage system is ready. Run triage now?
- Yes — process my inbox immediately
- No — I'll invoke it separately
If yes → transition directly to Triage Mode below.
Privacy Boundary
Never persist passwords, full account numbers, SSNs, or other sensitive credentials in KB files. If volunteered during the interview, acknowledge but don't store — write [stored separately by user] in the relevant file.
TRIAGE MODE — Recurring Email Triage
Runs when KB exists. Light-intake by design.
DRAFTS ONLY — Never Send
This skill creates drafts. It NEVER sends.
Non-negotiable. The scripts/draft_safety_validator.py enforces it post-run. Any send-shaped tool call in the action log fails validation. See references/drafts_only_safety.md.
Step 0: Grill-Me Intake (0–2 Optional Override Questions)
Q1 (only when on-demand run is outside normal cadence):
Override the default 9-hour search window? yes (specify hours) / no.
Why I'm asking: If you're running outside your normal cadence, you may want a wider or narrower window.
Q2 (only when user invokes with category-skip intent):
Skip any categories this run? E.g., "skip newsletters".
Why I'm asking: Sometimes you just want to scan opportunities or clear active threads.
Max 2 questions. Default invocations skip both and run with KB-default preferences.
Step 1: Determine Search Window
Use scripts/search_window_calculator.py --cadence <CADENCE> --now <ISO>:
| Cadence (from email-taxonomy.md) | Default window |
|---|
| once daily | 26h |
| 2x daily | 9h |
| 3x daily | 6h |
| on-demand only | 24h (asks Q1) |
Step 2: Email Search
Two queries:
- Primary: Inbox + sent after
window_start
- Secondary: Starred unread (catch flagged items missed in primary)
Collect per email: sender, subject, date, snippet, thread ID, labels.
Provider adapter:
| Provider | Tool |
|---|
| Gmail | Gmail MCP |
| Outlook / Microsoft 365 | Outlook MCP |
| IMAP (Fastmail, ProtonMail, etc.) | IMAP MCP if available; halt otherwise |
| (no email tool available) | Halt: "No email tool registered for this session." |
Step 3: Classification
Apply taxonomy from email-taxonomy.md. For lowest-priority category (newsletters/automation/spam): skip thread reads entirely. For everything else: read full thread.
Step 4: Sender Research
For senders not in tracker / blocklist / prior logs:
- Check
blocklist.md → if matched, auto-skip
- Check
tracker.md → if known thread, note existing context
- For opportunity senders: web search for legitimacy, social presence, intermediary status
Skip entirely for: known senders, internal email, automated notifications, obvious low-priority.
Step 5: Recommendations
Apply evaluation-framework.md (skip this step entirely if file doesn't exist):
| Category | When | Output |
|---|
| TAKE IT | Meets criteria | Recommend engaging; draft reply (Step 6) |
| WORTH CONSIDERING | Has potential, needs user judgment | Surface context; draft for user to edit |
| PASS | Doesn't meet criteria | Brief "why" (1–3 sentences); draft polite decline |
| FLAG FOR REVIEW | Unusual; needs direct user decision | Surface fully; NO draft |
See references/triage_decision_framework.md for the framework canon.
Step 6: Drafts
Draft using email-patterns.md voice rules. NEVER call any send operation. Only create drafts.
Draft body must honor:
- Voice register + forbidden tokens (S3.Q2 pet peeves)
- Sign-off patterns + persona context
- Hard rules (S3.Q6 — non-negotiable)
- Reply length per
email-patterns.md
Do NOT draft for: newsletters, automation, FYI threads, already-replied threads, blocked senders.
Tone by recommendation:
- TAKE IT → engaged + concrete next step
- WORTH → curious + 1–2 clarifying questions
- PASS → polite decline + brief reason (no hedging promises)
- FLAG → NO draft
Step 7: Report Delivery
Honor preference from email-taxonomy.md. Default: email draft to self.
Subject: Inbox Triage — [Day], [Month Date] ([Run Label])
Sections (in order):
- Overview — 2–3 sentences. What happened? Anything urgent?
- Stats — Processed / drafts created / action needed / skipped
- Action Needed — Overdue items, decisions, drafts to review, deadlines
- Quick Reference — One line per email:
**Sender** — summary + recommendation
- Detailed Cards — Opportunities, active threads, flags. No draft text previews.
- Footer — Timestamp + KB update summary
HTML formatting (if applicable): inline CSS only (Gmail strips <style>). Color-coded: green → TAKE IT, amber → WORTH CONSIDERING, red → PASS, purple → FLAG FOR REVIEW, blue → active conversation.
Step 8: Knowledge Base Update
blocklist.md: append new declined senders + patterns; remove if user overrode.
tracker.md: append new follow-ups, update existing, mark resolved, flag overdue, remove resolved items older than 30 days, add entry to update log.
After 5+ runs, suggest KB improvements: "You always decline emails from X — add as auto-skip?"
Step 9: Internal Log
Save to ${WORKSPACE}/Email/triage-log/[YYYY-MM-DD]-[run-label].md:
- Emails processed with classifications
- Recommendations made
- Drafts created (with thread refs)
- KB updates made
- Notable observations
Audit trail for scripts/draft_safety_validator.py.
Step 10: Empty Inbox Handling
Even with zero new emails:
- Check
tracker.md for items due today or overdue
- Generate minimal report: "No new actionable emails since last run"
- Flag overdue items
Skip Steps 3–6 entirely on empty inbox.
UPDATE MODE — Refresh Preferences
Triggered by /notion inbox update or "update my inbox preferences."
- Detect existing files at
${WORKSPACE}/Email/
- For each file, ask: replace / merge / skip
- Walk only the sections whose files the user chose to update
- Skip sections whose files the user kept
Critical Rules
- DRAFTS ONLY — NEVER SEND. Non-negotiable.
- Privacy. No passwords / credentials in KB files.
- Accuracy over speed. When unsure, flag for review.
- Respect the KB. Documented preferences are source of truth. Don't override with judgment.
- Transparency. Note every KB change in the triage log.
- First runs need oversight. Document this expectation for the user.
Error Handling
| Situation | Behavior |
|---|
| No KB + triage invoked | Run setup first, then triage |
| KB exists + setup invoked | Acknowledge; offer triage / update / both |
| Partial KB (missing files) | List gaps; offer full setup or fill missing sections only |
| Workspace inaccessible | Stop; tell user where files would go; ask for path |
| Email tool unavailable | Halt with clear message |
| User refuses voice samples | Use self-description; flag in patterns file that calibration may need iteration |
| User drops off mid-interview | Honor partial KB; committed files are usable |
| 100+ new emails | Flag volume; offer to focus on priority categories only |
| Sender in both blocklist and tracker | Tracker wins; note inconsistency in log |
Portability
- Claude Code CLI: Native — writes markdown files directly to filesystem, uses Gmail/Outlook MCP.
- Claude.ai web: Generate files as artifacts; instruct user to save to workspace.
Tooling
| Script | Role |
|---|
scripts/kb_validator.py | Validates the 7-file KB after setup (required files present, conditional files match sections run, headers + structure correct). |
scripts/section_progress_tracker.py | JSON-backed walk state across the 8 interview sections. |
scripts/voice_sample_analyzer.py | Extracts voice patterns from pasted sent-email samples. |
scripts/kb_reader.py | Reads + validates the 7-file KB at triage start. Halts on missing required files. |
scripts/search_window_calculator.py | Computes window_start from cadence + current time. Returns run_label. Honors Q1 override. |
scripts/draft_safety_validator.py | Post-run scan of action log for any send-shaped tool call. FAIL if detected. |

Anti-Patterns To Reject
- Sending emails — drafts only, non-negotiable
- Generating all KB files at once instead of walking sections
- Asking all questions in one batch (breaks grill-me discipline)
- Persisting sensitive credentials in KB
- Operating triage without KB files
- Skipping KB updates at end of triage run
- Overriding user's documented preferences with own judgment
- Skipping the "why this question matters" on setup questions
- Including draft text previews in triage report (drafts are already in email client)
- Provider lock-in without adapter pattern
