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.

SkillSpector: 2 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 | $0.00036 | $0.00577 |
| Opus 5.5 | $0.00014 | $0.00231 |
| Sonnet 5.5 | $0.00007 | $0.00115 |
| Haiku 4.5 | $0.00004 | $0.00058 |
Grade B, and why
http scanned grade B 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 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
Caddy runs as a PM2 service (user-space, no sudo needed for daily operations). What it actually says
HTTP Layer (C6)
User-space Caddy web server providing:
- HTTPS with automatic Let's Encrypt certificates
- File sharing via
~/zylos/http/public/ - Health check endpoint
- Component reverse proxy routes (auto-configured by
zylos add)
Architecture
| Component | Path |
|---|---|
| Binary | ~/zylos/bin/caddy |
| Caddyfile | ~/zylos/http/Caddyfile |
| Public files | ~/zylos/http/public/ |
| Access log | ~/zylos/http/caddy-access.log |
| Domain config | ~/zylos/.zylos/config.json |
Caddy runs as a PM2 service (user-space, no sudo needed for daily operations).
Setup
Caddy is set up automatically during zylos init:
- Downloads Caddy binary to
~/zylos/bin/caddy - Prompts for domain, stores in
config.json - Generates Caddyfile
- Sets port binding capability (
setcap, one-time sudo) - Starts via PM2
To re-run setup: zylos init
Endpoints
| Path | Description |
|---|---|
/ |
File listing or index.html |
/*.md |
Markdown documents (served as plain text) |
File Sharing
Place files in ~/zylos/http/public/ to share:
cp document.md ~/zylos/http/public/
# Access at: https://your.domain.com/document.md
Component Routes
Components declare http_routes in SKILL.md frontmatter. Routes are auto-managed via marker blocks in the Caddyfile by zylos add/upgrade/remove.
Troubleshooting
# Check Caddy status
pm2 logs caddy
# Validate Caddyfile
~/zylos/bin/caddy validate --config ~/zylos/http/Caddyfile --adapter caddyfile
# Reload after manual Caddyfile edits
pm2 reload caddy
# Access logs
tail -f ~/zylos/http/caddy-access.log
Port Binding
On Linux, Caddy needs CAP_NET_BIND_SERVICE to bind ports 80/443:
sudo setcap cap_net_bind_service=+ep ~/zylos/bin/caddy
This is set automatically during zylos init. If the binary is replaced (e.g., after an update), re-run the command above.
What ships with it
3 files 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.

http 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 577 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
