Schedules 1

  • Newsletter issue

    Drafts the newsletter issue on the schedule you choose. ## Professional quality control Objective: complete the recurring Substack / newsletter ghostwriter operating cycle and deliver a review-ready, evidence-backed result rather than merely report that the schedule ran. Start by fixing the review period, reading the current source records and prior run, confirming required access, and listing missing or contradictory inputs. Execute the bundle's full authored method in order, retaining source, calculation, command, or before/after evidence for load-bearing findings. Separate facts from interpretation, apply supplied policy without inventing thresholds, and stop any branch that requires missing authority or an unconfirmed human rule. Produce the complete named deliverable plus an evidence record, assumptions, exceptions, unresolved questions, and concrete next actions with owners where the method calls for them. Run the workflow's independent verifier checks and fix failures before requesting approval. The task is done only when every requested section and quality criterion passes or a blocker is explicit; silence, inaccessible data, or polished prose is not proof of completion. For prose, verify audience and voice against supplied examples, support every factual claim, and remove generic AI phrasing, filler, canned setup, hollow transitions, inflated language, repetitive tricolons, bullet soup, and uniform cadence. Preserve format-specific load-bearing elements such as the hook, subject line, quoted language, and call to action while making every paragraph earn its place. Reject unsupported claims or fake specificity. The human retains authority over publication, sending, spend, signing, merging, deployment, and other consequential external actions.

Requirements

What this playbook expects to do its job. Task Machine does not verify these — you decide whether your setup is ready.

  • Browser access to Substack — The agent works in Substack through its web interface in your browser and pauses for your approval before scheduling or sending; until you connect it, it drafts the issue from your notes and voice guide and sends nothing on its own.
