Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00017 | $0.00338 |
| Opus 5 | $0.00009 | $0.00169 |
| Sonnet 5 | $0.00003 | $0.00068 |
| Haiku 4.5 | $0.00002 | $0.00034 |
Grade A, and why
cron-scheduling 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 9d 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.
What it actually says
Cron Scheduling
Use this skill when the user asks to schedule, reschedule, or cancel reminders/tasks for later.
Before creating a schedule, confirm:
- exact schedule timing (cron expression),
- timezone (IANA, for example
America/Los_Angeles), - task message content.
If the request is ambiguous, ask a follow-up question before adding a schedule.
Commands
Use the embedded CLI. It talks to the backend schedule service and stores schedules in SQLite.
middleman schedule add \
--cron "0 9 * * 1-5" \
--message "Remind me about the daily standup" \
--description "Daily standup reminder" \
--timezone "America/Los_Angeles"
One-shot schedule (fires once at the next matching cron time):
middleman schedule add \
--cron "30 14 * * *" \
--message "Check deployment status" \
--description "One-time deployment check" \
--timezone "America/Los_Angeles" \
--one-shot
Remove a schedule:
middleman schedule remove \
"<schedule-id>"
List schedules:
middleman schedule list
Override manager context manually when needed:
middleman schedule list --manager "manager"
Output
All commands return JSON:
- Success:
{ "ok": true, ... } - Failure:
{ "ok": false, "error": "..." }
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.

cron-scheduling is a skill published in the GitHub repository SawyerHood/middleman (181 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 17 tokens to every session and 338 once invoked, about $0.0001 per session on Opus 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 2026-08-30.

foundry-config-setup
Resolve missing setup caused by a hardcoded Foundry project endpoint or model in a sample. Use when a sample fails because it uses a placeholder/hardcoded projectendpoint (for example "https://your-project.services.ai.azure.com") or a hardcoded model instead of reading them from the environment.
deploy-docker-compose
Run the Omnigent server as a Docker compose stack (server + Postgres) on any Docker host — your laptop, a VPS, EC2 by hand, or as the base layer of any container-platform deploy. Invoke when the user wants to build the image, bring up the compose stack, debug the stack on a host they already have, or extend the stack…
