A tool for creating, listing, and deleting cron schedules that send instructions to an agent at set times. Cron is a system for running recurring tasks, such as every day or every 30 minutes.

Use it to schedule recurring messages for configured agents, inspect existing schedules, or remove schedules that are no longer needed.

It removes the need to remember or manually repeat routine agent tasks.

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	$0.00080	$0.01164
Opus 5.5	$0.00032	$0.00466
Sonnet 5.5	$0.00016	$0.00233
Haiku 4.5	$0.00008	$0.00116

Security

Grade A, and why

schedule 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/schedule.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Schedule Skill

Manage cron-based scheduled tasks that deliver messages to the tinysdlc incoming queue. Each schedule fires at a cron interval and writes a routed message (@agent_id <task>) to queue/incoming/, where the queue processor picks it up and invokes the target agent.

Commands

Use the bundled CLI scripts/schedule.sh for all operations.

Create a schedule

scripts/schedule.sh create \
  --cron "EXPR" \
  --agent AGENT_ID \
  --message "Task context for the agent" \
  [--channel CHANNEL] \
  [--sender SENDER] \
  [--label LABEL]

--cron — 5-field cron expression (required). Examples: "0 9 * * *" (daily 9am), "*/30 * * * *" (every 30 min), "0 0 * * 1" (weekly Monday midnight).
--agent — Target agent ID (required). Must match an agent configured in settings.json.
--message — The task context / prompt sent to the agent (required).
--channel — Channel name in the queue message (default: schedule).
--sender — Sender name in the queue message (default: Scheduler).
--label — Unique label to identify this schedule (default: auto-generated). Use a descriptive label for easy management.

List schedules

scripts/schedule.sh list [--agent AGENT_ID]

Lists all tinysdlc schedules. Optionally filter by --agent to show only schedules targeting a specific agent.

Delete a schedule

scripts/schedule.sh delete --label LABEL
scripts/schedule.sh delete --all

Delete a specific schedule by label, or delete all tinysdlc schedules.

Workflow

Confirm the target agent ID exists (check settings.json or ask the user).
Determine the cron expression from the user's description (e.g., "every morning" → "0 9 * * *").
Compose a clear task message — this is the prompt the agent will receive.
Run scripts/schedule.sh create with the parameters.
Verify with scripts/schedule.sh list.

What ships with it

2 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.

Changes

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 is a skill published in the GitHub repository Minh-Tam-Solution/tinysdlc (10 stars, last pushed 8mo ago), licensed MIT. It adds 80 tokens to every session and 1,164 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
