Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00000 | $0.09787 |
| Opus 5 | $0.00000 | $0.04894 |
| Sonnet 5 | $0.00000 | $0.01957 |
| Haiku 4.5 | $0.00000 | $0.00979 |
Grade A, and why
schedule-crons scanned grade A with 1 finding 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 2d 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.

Schedule Crons
Re-create all session cron jobs for Sutando. Run this on startup or after a session restart.
Usage: /schedule-crons
How It Works
Jobs are defined per host in <workspace>/hosts/<hostname>/crons.json — per-host, synced + backed up via the vault (carried as part of the hosts/*/ per-host subtree (#1717), which is hostname-qualified so it never collapses across hosts; see docs/workspace-hosts-convention.md and docs/workspace-per-host-paths.md). <hostname> is bash scripts/sutando-config.sh host-label — the canonical per-host label ($SUTANDO_HOST_LABEL > scutil LocalHostName > short hostname), matching the sync layer's host slug. (Do NOT use a bare hostname | sed 's/\..*//': a DHCP lease can drift the hostname (e.g. Comcast → Chis-MBP) and split per-host paths from the stable label; #1745.) A template is in crons.example.json (in this skill dir, version-controlled). Copy it on first setup:
WS="$(bash scripts/sutando-config.sh workspace)"; H="$(bash scripts/sutando-config.sh host-label)"; mkdir -p "$WS/hosts/$H"
cp skills/schedule-crons/crons.example.json "$WS/hosts/$H/crons.json"
(Migrated from the old skills/schedule-crons/crons.json, which lived in the code checkout — misfiled per the workspace contract, and per-host-but-unsynced. The new path is proper per-user state: backed up + visible across hosts, each host keeping its own cron set.)
Each entry has:
name— unique identifier (used to avoid duplicates)cron— 5-field cron expressionprompt— the prompt to run (direct text)prompt_skill— OR a skill to invoke (e.g. "morning-briefing" →/morning-briefing)loop(optional, value"dynamic") — declares a dynamic (self-pacing) loop using the built-in/loopprimitive. An entry with no interval (nocronfield) +loop: "dynamic"is run by schedule-crons as/loopwithout an interval (see step 3) — which is exactly the built-in adaptive mode: the loop self-paces via ScheduleWakeup, deciding each next delay by its own judgment. Optionalloop_hint(free text) guides that pacing (e.g. "~10 min when owner active, ~40 min quiet"). Durable because schedule-crons re-launches it every boot; adaptive because that's what/loop-no-interval already is. No min/max/signal schema and no custom gate — the built-in does the pacing. Example:{name:"inbox-score", prompt_skill:"inbox-score", loop:"dynamic", loop_hint:"…"}.execution(optional, value"codex-task") — opt this entry into the durable OS-backed Codex runner instead of session cron registration. Codex entries may also settimezone(IANA name, defaultAmerica/Los_Angeles),delivery: "proactive",retry_minutes(default 15),max_attempts(default 3), andactive_stale_minutes(default 60). Jobs require this explicit opt-in except for the canonicalmain-loopwhile the selected runtime is Codex; the runtime-specific exception is described below.launchd(optional bool) — whentrue, the entry is owned by the OS-level cron-runner (src/cron-runner.py, installed viasrc/install-cron-runner-launchd.sh), NOT by this session skill./schedule-cronsskips these so the two schedulers never double-fire. Use it for daily-deliverable crons that must fire even when no Claude session is idle (the reliability fix for the 2026-07-02 silent 6am-digest miss).monitor(optional object) — declares a persistent Monitor-based driver, NOT a cron: the entry is armed via theMonitortool and re-armed on every/schedule-crons, so it survives restarts the way the task watcher (step 1.5) does. Shape:{"command": "<shell to run>", "description": "<one-line>", "match": "<argv substring that detects a running instance>"}. It is NOTCronCreated and NOT counted in the stamp'sregistered(it is not a session cron). Armed in step 5.4. Use it for a continuous event-emitting driver (e.g. the content-loop) that must re-arm across restarts.artifact(optional string) — the filename STEM of the dated output this job produces, e.g."fleet-growth"forfleet-growth-2026-08-18.mp4. Read byhealth-check.py'sdaily-cron-punctualityprobe. Without it the probe infers a stem from the last hyphenated token of the job name, sotalk-events-nightlylooks fornightly-<date>.*, never observes the real artifact, and reports the job UNCHECKED forever. Declare it whenever the name does not already equal the stem.conditional(optional bool) — settruewhen the job runs on schedule but produces output only if there is new input (a nightly render with no new beats). The punctuality probe then treats "no artifact today" as evidence of nothing rather than a miss; lateness is still measured from the artifacts that do exist. On macOS, the Codex core launcher automatically reconciles ordinary fixed-interval entries to this owner because Codex has no sessionCronCreatesurface. It preservesmain-loop, dynamic loops, and entries already owned byexecution: "codex-task", and initializes the runner boundary before changing ownership so activation never replays an old action backlog.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

schedule-crons is a skill published in the GitHub repository sonichi/sutando (392 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 9,787 tokens. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
