The seed prompt below is the published Anthropic example this template was derived from; your skill should generalize it for repeated, hands-off use. ## Outcome Claude in Chrome reads your calendar, pulls context from email threads, flags which meetings need prep, and books rooms for the ones missing them. TODO: Restate the outcome for YOUR context in one sentence: who runs this, on what input, producing what artifact, how often. ## Seed prompt (verbatim from source, © Anthropic PBC) ```text Look at my calendar and help me get ready for tomorrow. For each meeting: Tell me if it's internal or external (check the attendee domains). Find any recent email threads with those attendees about this topic. Flag if the meeting is missing a room (for in-person) or a video link (for remote). If it is, assign one to the meeting. For external meetings, note anything I should review beforehand, like relevant docs attached to the meeting or related emails. Give me a quick prep summary for the day, finding what needs my attention before I show up. ``` ## Required context and inputs - Google Calendar open showing tomorrow's date, logged in - Gmail open in another tab, logged in - TODO: exact file paths / folders / message formats this skill should expect - TODO: domain context the model cannot infer (naming conventions, thresholds, house style) ## Tools, connectors, APIs, and authentication - Claude in Chrome extension - Gmail - Google Calendar - TODO: confirm which connectors are enabled in the runtime that will execute this skill - Authentication: connectors authenticate via their own OAuth flows — this skill must NEVER ask for, store, or echo credentials, tokens, or API keys. If auth is missing, stop and tell the user which connector to enable. ## Permissions and sensitive actions - Reads: TODO (folders, channels, records this skill may read) - Writes: TODO (what it may create/modify, and where) - Held back for the primary agent / human: sending external communications, financial transactions, deleting or overwriting originals, submitting web forms, and ANY click that finalizes state on a third-party site (browser-use skill: show a review step first) ## Workflow 1. Describe the task 2. Give Claude context 3. What Claude creates 4. Follow up prompts 5. Tricks, tips, and troubleshooting TODO: adapt the steps above (from the source page) into imperative instructions for the executing agent, including what to do between steps. ## Decision points - TODO: list each point where the skill must choose between paths, with the rule to apply - Default rule: prefer the reversible option; when two readings of the input are plausible, surface both rather than picking silently. ## Validation criteria - Output matches the outcome statement above (spot-check against the seed prompt's asks) - Every factual claim is traceable to a provided input, connector record, or cited source - Nothing is submitted/saved on a website without showing the user a review step first - Site actions limited to the domains named in the workflow - TODO: add one domain-specific check a reviewer in your org would apply ## Failure modes and fallbacks - Connector unavailable or unauthenticated → pause, tell the user exactly which connector to enable and why; offer a degraded run from uploaded files - Page fails to load or selector drifts → retry once, then stop and report; never guess at form fields - Ambiguous or missing input → ask one targeted question; if unattended, state the assumption inline and proceed - Any step would take a sensitive/irreversible action → stop and hand back to the user (see Delegation) ## Delegation Apply the repo's delegation policy (`docs/delegation-policy.md` — bundle or restate it if you install this skill outside the repo). Defaults for this template: - Run single-agent unless a step fans out over independent items (files, records, vendors, channels). Only independent work parallelizes. - Each delegated task must ship with: the minimal context slice it needs, an explicit output contract, a validation check the primary agent runs on the result, and a fallback if it returns empty or fails. - Final review, synthesis, and every sensitive action listed above stay with the primary agent. - TODO: name the concrete subtasks (if any) that qualify for delegation here. ## Attribution Derived from [Prepare and plan from your calendar](https://claude.com/resources/use-cases/prepare-and-plan-from-your-calendar) (retrieved 2026-07-26).
