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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00089 | $0.02129 |
| Opus 5 | $0.00044 | $0.01064 |
| Sonnet 5 | $0.00018 | $0.00426 |
| Haiku 4.5 | $0.00009 | $0.00213 |
Grade A, and why
cron-task-creator 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 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.

The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create and manage octo cron tasks
octo runs an agent prompt on a schedule. Each task is a JSON file in
~/.octo/tasks/, loaded by the scheduler inside octo serve. When a task
fires, the scheduler runs one agent turn with the task's prompt and reuses the
same session across runs, so the task accumulates history from earlier runs.
Each run is bounded by a 30-minute wall-clock timeout (the only hard cap on
a run).
Task schema
| Field | Required | Meaning |
|---|---|---|
name |
yes | Human-readable task name |
cron |
yes | Schedule expression — see format below |
prompt |
yes | The prompt sent to the agent on each run |
model |
no | Model override; defaults to the server's model |
agent |
no | "general" or "coding" |
directory |
no | Working directory the run executes in |
notify |
no | IM chats to push each run's final reply (or failure) to — see the notify table |
enabled |
yes | Whether the schedule is active |
id, created_at, last_run, session_id, session_group_id are
server-managed — never set them by hand except id in the file-write fallback
below.
Every run creates a fresh session (titled by the run's local date and time) and files it under a per-task session group named after the task, so a task's runs cluster together in the sidebar. The group is created with the task and renamed/deleted along with it. Runs never share a session — each starts from a clean transcript.
Cron expression — 6 fields, seconds first
The scheduler uses robfig/cron with a seconds field. A standard 5-field crontab line is invalid — always prepend a seconds field:
seconds minutes hours day-of-month month day-of-week
| Want | Expression |
|---|---|
| Every day at 09:00 | 0 0 9 * * * |
| Every hour | 0 0 * * * * |
| Weekdays at 18:30 | 0 30 18 * * 1-5 |
| 1st of each month at 08:00 | 0 0 8 1 * * |
Descriptors also work: @hourly, @daily, @weekly, @every 90m. Times are
in the server's local timezone.
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.
- 9d ago First seen · 163 lines · 89 tokens per session scan A bde60e603cb1
cron-task-creator is a skill published in the GitHub repository open-octo/octo-agent (97 stars, last pushed yesterday), licensed MIT. It adds 89 tokens to every session and 2,129 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
