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 | $0.00023 | $0.00593 |
| Opus 5 | $0.00012 | $0.00296 |
| Sonnet 5 | $0.00005 | $0.00119 |
| Haiku 4.5 | $0.00002 | $0.00059 |
Grade A, and why
restart-claude 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 13d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Restart Claude Code Skill
Restart Claude Code session - sends /exit and lets activity-monitor daemon handle the restart.
When to Use
- After changing Claude Code settings, hooks, or keybindings
- When Claude needs to reload configuration
- To clear temporary state without upgrading
- User explicitly asks to restart
Pre-Restart Checklist
Before sending /exit, complete these steps in order:
1. Stop background tasks
Check for running background agents (Task tool). If any are active, stop them to avoid orphaned work.
2. Sync memory
Update memory files (state.md, sessions/current.md, etc.) to preserve important context that would otherwise be lost on restart.
3. Write a session handoff summary
Write a brief message covering:
- What was being worked on (active tasks, user requests in progress)
- Current state (what's done, what's pending, any blockers)
- What the next session should pick up (if anything)
4. Send the handoff summary
Send the full handoff summary to the internal void channel via C4:
cat <<'EOF' | node ~/zylos/.claude/skills/comm-bridge/scripts/c4-send.js "void" "session-handoff"
<handoff summary>
EOF
The void channel is record-only: the message is stored in C4 conversation
history (so the restarted session's startup hook, c4-session-init, includes
it in startup context) but is never delivered to any real channel or display
surface.
Do not send the full handoff summary to the active external user channel
(Telegram, Lark, Feishu, HXA, etc.). Handoff summaries are operational context
for the next agent session and may contain task state from outside the current
conversation. If the user is actively waiting, send only a short user-facing
notice to their current reply via path, without internal task inventory or
cross-channel context.
5. Enqueue /exit
node ~/zylos/.claude/skills/comm-bridge/scripts/c4-control.js enqueue --content "/exit" --priority 1 --block-queue-until-idle
What ships with it
1 file 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.
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.

restart-claude is a skill published in the GitHub repository zylos-ai/zylos-core (1,151 stars, last pushed 3d ago), licensed MIT. It adds 23 tokens to every session and 593 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.
