When your agent uses it

  • Tasks that involve Email management

Example prompts

  • “/spark-recipe-inbox-zero”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Scan by category (use recipe-inbox-by-category)
  2. Review and act on each email
  3. Batch process notifications and newsletters
  4. Verify

What it can do on your machine

Read from SKILL.md and the folder at commit cb20383. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    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

Spark Recipe Inbox Zero loads about 627 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 217 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~627

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); files beside SKILL.md are not scanned.

Recipe: Inbox Zero

Process the inbox to zero using category-first triage. Work through categories in priority order, then take action on each email.

Prerequisite: Read the use-spark base skill for command reference and filter syntax.

Access level required: triage.

Steps

Step 1: Scan by category (use recipe-inbox-by-category)

Process inbox in priority order:

bash
spark emails Inbox --filter "category:priority is:unread"
spark emails Inbox --filter "category:personal is:unread"
spark emails Inbox --filter "category:invitation"
spark emails Inbox --filter "category:notification is:unread"
spark emails Inbox --filter "category:newsletter newer_than:7d"
Step 2: Review and act on each email

For emails that need attention, read the thread:

bash
spark thread <id>

Then decide the action:

Archive - handled or informational, no further action needed:

bash
spark action archive <id>

Move to folder - needs filing:

bash
spark action moveToFolder <id> --folder "user@example.com:Projects"

Mark as done - completed/resolved:

bash
spark action markAsDone <id>

Pin - important, need to come back to:

bash
spark action pin <id>

Snooze - not relevant now, revisit later:

bash
spark action snooze <id> --date 2026-04-10

Set aside - save for later review:

bash
spark action setAside <id>
Step 3: Batch process notifications and newsletters

For categories with many items, batch archive:

bash
spark action archive <id1> <id2> <id3> <id4>
Step 4: Verify
bash
spark emails Inbox --filter "is:unread"

Confirm the inbox is clear or report what's left.

Tips

  • Work through categories in order - don't jump to newsletters before handling people mail.
  • Batch archive is efficient for notifications: list them, confirm with the user, then archive all at once.
  • Pin or snooze items that need future attention rather than leaving them unread.
  • If an email needs a reply, use spark draft --reply-to <id> and then archive - the draft keeps the task alive.
  • If you spot miscategorized contacts while triaging, use spark contact-action changeCategory* to reclassify all future mail from that sender.
