Zylos is open-source infrastructure that gives an AI agent persistent memory, scheduled activity, communication channels, and the ability to maintain and extend itself. Individuals and teams use it with Claude Code or Codex through Telegram, Lark, or a web console. Its catalogue add-ons define settings, instructions, and skills for operating the agent.
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.

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 | $0.00036 | $0.00332 |
| Opus 5.5 | $0.00014 | $0.00133 |
| Sonnet 5.5 | $0.00007 | $0.00066 |
| Haiku 4.5 | $0.00004 | $0.00033 |
Grade A, and why
scheduler 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 2mo 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
Task Scheduler (C5)
Enables Claude to work autonomously by dispatching scheduled tasks via C4 comm-bridge.
How It Works
- Activity Monitor writes state to
~/zylos/activity-monitor/agent-status.json - Scheduler checks for pending tasks that are due
- If runtime is alive, dispatches task to C4 comm-bridge
- C4 handles execution control (idle waiting, priority queueing)
- Task sent to Claude based on priority and idle requirements
CLI
~/zylos/.claude/skills/scheduler/scripts/cli.js <command>
| Command | Description | Reference |
|---|---|---|
add <prompt> [options] |
Add a new task | references/add.md |
update <task-id> [options] |
Update an existing task | references/update.md |
list / next / running / history |
Query tasks | references/query.md |
done / remove / pause / resume |
Task lifecycle | references/lifecycle.md |
Timezone
Resolves TZ: ~/zylos/.env > process.env.TZ > UTC. Times are parsed and displayed in configured timezone. DB stores UTC. See references/config.md for details.

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.

scheduler is a skill published in the GitHub repository zylos-ai/zylos-core (1,160 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 332 once invoked, about $0.0001 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 2026-08-30.
