What it does

Spark Recipe Invitation Manager is an agent skill from readdle/spark-cli-skills. Process pending calendar invitations: check availability and present a decision list with recommendations.

Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The licence is MIT.

Example prompts

  • “/spark-recipe-invitation-manager”

Workflow steps

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

  1. List pending invitations
  2. Read each invitation
  3. Check availability for each
  4. Present a decision list
  5. Check invitation responses

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 Invitation Manager loads about 608 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 249 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~608

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: Invitation Manager

Process pending calendar invitations by checking availability for each and presenting a decision list with recommendations.

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

Access level required: read-only.

Steps

Step 1: List pending invitations
bash
spark emails Inbox --filter "category:invitation"

Collect all pending invitations. Note the senders, subjects, and IDs.

Step 2: Read each invitation

For each invitation, read the thread to understand the meeting details:

bash
spark thread <id>

Note the proposed time, attendees, and purpose.

Step 3: Check availability for each

For each invitation's proposed time, check whether the user is free:

bash
spark events --today

Or for a specific date range:

bash
spark events --start 2026-04-14 --end 2026-04-14

For a broader view:

bash
spark availability --start 2026-04-14 --end 2026-04-14
Step 4: Present a decision list

Summarize each invitation with a recommendation:

  • Accept - the user is free at the proposed time
  • Conflict - the user has an overlapping event (name the conflict)
  • Needs discussion - the user is technically free but the meeting needs clarification
Step 5: Check invitation responses

Review any invitation responses the user has received:

bash
spark emails Inbox --filter "category:invitation_response"

Report who accepted, declined, or proposed alternative times.

Tips

  • Process invitations daily - they're time-sensitive and forgetting one can mean missing an important meeting.
  • Use availability to quickly check free slots rather than scanning through events manually.
  • Invitation responses (category:invitation_response) are a separate category - check them to see who RSVPed.
  • For recurring meeting invitations, read the thread to check if the pattern works long-term, not just the next occurrence.
  • When there's a conflict, suggest an alternative time by checking availability around the proposed date.
  • Combine with recipe-schedule-meeting when an invitation leads to rescheduling.
