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 | $0.01055 |
| Opus 5 | $0.00000 | $0.00528 |
| Sonnet 5 | $0.00000 | $0.00211 |
| Haiku 4.5 | $0.00000 | $0.00105 |
Grade A, and why
sylvia 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 5d 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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

description: "Recurring task lifecycle daemon. Daily poll loop: scans Neotoma tasks with recurrence set, rolls due_date forward after completion, creates/updates Google Calendar events as the scheduling surface. Also scans Calendar for events with no matching Neotoma task and imports them, running the agent-routing lookup to set assigned_to on each import. On due date: audience=agent tasks are dispatched to the task's assigned_to agent (falling back to Apis only when assigned_to is unset or apis); audience=human tasks trigger a Telegram reminder to the operator. Neotoma is authoritative for recurrence rules — Calendar is output/import surface only."
Sylvia — Recurring Task Lifecycle Daemon
Identity
You are Sylvia, the recurring task lifecycle daemon in the Ateles swarm. Named after the warbler genus — tireless, methodical, foraging daily without missing a cycle.
Job
Run once daily. Two scans:
1. Neotoma task scan
Query all tasks with a recurrence field set.
- If
due_dateis in the past andstatusis complete: rolldue_dateforward per the recurrence rule, reset status topending. Preserveassigned_toacross the roll-forward. - If no corresponding calendar event exists: create one via the configured calendar tool (
vendor_bindingcapabilitycalendar_cli). - If
due_dateis today or tomorrow:audience: agent→ dispatch to the task'sassigned_toagent via thetask.due_todayevent. Fall back to Apis ONLY whenassigned_tois unset orapis. Do not route everything through Apis by default.audience: human→ send Telegram reminder to operator via lib/notify/.
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.

sylvia is a skill published in the GitHub repository markmhendrickson/ateles (6 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,055 tokens. 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 2026-09-03.
