What is schedule-add?

A guided setup tool for running OneBrain skills automatically at chosen times. It helps configure schedules such as daily, weekly, monthly, or custom times without requiring knowledge of cron, a scheduling format.

Use it to choose a skill, set its frequency and time, review the schedule, and register it for automatic runs.

It removes the need to hand-edit configuration files or learn cron syntax.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00037	$0.02406
Opus 5	$0.00018	$0.01203
Sonnet 5	$0.00007	$0.00481
Haiku 4.5	$0.00004	$0.00241

Measured 6d ago against content hash 4b23ac9f190f, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-05, from the pricing page.

Security

Grade A, and why

schedule-add scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/schedule-add — Interactive scheduler wizard

Purpose

For users who don't want to hand-edit onebrain.yml or learn cron syntax. Walks through:

Which skill to schedule
How often (Daily/Weekly/Monthly/Custom)
What time
Confirms cron preview
Writes to onebrain.yml + runs onebrain schedule register

Skill flow

Step 0: First-run preset detection (skip if schedule already has entries)

Read onebrain.yml. Check if the schedule: key exists AND its value is a non-empty list.
- If schedule: is missing, null, or [] → continue with this step (preset selector).
- If schedule: has one or more entries → skip Step 0 entirely; go straight to Step 1.
Read the canonical preset tier table from .claude/plugins/onebrain/skills/_shared/schedule-presets.md. The four tiers are defined there — never duplicate them inline in this skill file.
Show preset selection via AskUserQuestion:
- Tier 1 — Minimal (1 entry: /daily 09:00 every day)
- Tier 2 — Essentials (Recommended) (3 entries: /daily, /weekly Friday, /recap Sunday)
- Tier 3 — Maintenance Plus (6 entries: Essentials + /doctor monthly + /tasks daily + onebrain search reindex Sunday command-mode entry)
- Tier 4 — Custom (skip presets, go to manual wizard)
Apply the chosen tier:
- Tier 1, 2, or 3: atomically write the preset entries (verbatim from _shared/schedule-presets.md) to onebrain.yml schedule: block (load → mutate → write entire file; use a tmp file + rename). Then run onebrain schedule register. Confirm: ✓ Installed Tier N preset (M entries).
- Tier 4 (Custom): fall through to Step 1 (the existing skill picker wizard).
On Tier 1/2/3 success → the skill exits here. The user has scheduled entries. Subsequent invocations of /schedule-add will see schedule: is non-empty and skip Step 0, falling straight into the manual wizard for adding additional entries.

Edge cases

onebrain.yml missing entirely → wizard creates it with the preset entries as the only content of a new schedule: block.
onebrain.yml has schedule: as a comment or YAML null → treat as empty; proceed with preset selector.
Atomic write failure → rollback (do not leave partial state); report the YAML error and exit.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
