What it does

Email Triage is an agent skill from borghei/Claude-Skills. Classify a batch of emails into action categories (reply now, reply later, archive, delete, unsubscribe) and surface unsubscribe candidates. Use after a busy week, running inbox zero, or triaging email overload.

Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts, reference files and assets (for example `assets/gmail_filter_template.md`, `references/inbox_zero_method.md` and `scripts/email_classifier.py`).

It sits in Productivity & Automation, covering Email management. It works with Gmail. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.

When your agent uses it

  • Tasks that involve Email management

Example prompts

  • “/email-triage”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Export inbox to CSV with columns: subject,sender,snippet,received_at
  2. Run: python scripts/email_classifier.py inbox.csv
  3. Review action buckets; act on each in order

What it can do on your machine

Read from SKILL.md and the folder at commit 4a698e8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Email Triage loads about 928 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 397 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~928
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Email Triage

Classify a batch of email subjects + senders into action buckets and surface inbox-zero candidates.

Keywords

email, inbox, inbox zero, triage, unsubscribe, mailing list, mailbox, gmail, outlook, productivity

Clarify First

Before triaging, confirm these inputs. If any is unknown or vague, ASK — do not assume:

  • Inbox export fields — subject, sender, snippet drive classification accuracy; missing columns degrade the buckets
  • Priority / VIP senders — who always routes to reply_now regardless of content
  • Unsubscribe tolerance — purge all marketing vs keep newsletters you value; sets how aggressive the unsubscribe/delete buckets are

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Quick Start

  1. Export inbox to CSV with columns: subject,sender,snippet,received_at
  2. Run: python scripts/email_classifier.py inbox.csv
  3. Review action buckets; act on each in order

Core Workflows

Workflow 1: Weekly Inbox Triage
  1. Export the past week's inbox
  2. Run classifier
  3. Action in order: reply-now → reply-later (move to follow-up folder) → archive → unsubscribe → delete
  4. Apply Gmail filters (see assets/gmail_filter_template.md) so future similar emails route automatically

Time Estimate: 30-45 minutes for a busy week.

Workflow 2: Unsubscribe Pass
  1. Run classifier; review unsubscribe candidates
  2. Unsubscribe in batch (most senders honor unsubscribe links within ~10 days)
  3. For senders that don't honor, set Gmail filter to auto-delete

Time Estimate: 15 minutes per pass.

Show full SKILL.md (168 more words)Show less
Workflow 3: Inbox-Zero Reset
  1. Apply the full inbox-zero method from references/inbox_zero_method.md
  2. Move every email older than 30 days to archive (you'll find 1% later via search)
  3. Triage the remaining recent emails using the classifier

Time Estimate: 1-2 hours one-time; then 20 min/week to maintain.

Tools

email_classifier.py

Classifies email rows into action buckets using rule-based pattern matching on sender domain, subject line, and snippet.

bash
python scripts/email_classifier.py inbox.csv
python scripts/email_classifier.py inbox.csv --json

Action buckets:

  • reply_now — direct addressing, time-sensitive language, named-person sender
  • reply_later — informational threads, longer non-urgent
  • archive — receipts, confirmations, completed transactions
  • unsubscribe — newsletters, marketing, promotional
  • delete — spam patterns, low-signal senders
  • review — couldn't classify confidently

Reference Guides

  • references/inbox_zero_method.md — Method, daily routine, common pitfalls

Templates

  • assets/gmail_filter_template.md — Common Gmail filter recipes for the action buckets above

Best Practices

  • The 2-minute rule: if a reply takes < 2 minutes, do it now.
  • Don't archive instead of unsubscribing. Recurring senders compound — kill the source.
  • Process in batches. Constant inbox checking destroys focus more than email itself.
  • Inbox is not a to-do list. Move action items to a real task tool.
