Nacos is a platform that lets cloud-native applications discover services, check their health, and manage service configuration dynamically. It is used with microservices and services such as Dubbo, gRPC, Spring Cloud, and Kubernetes, including centralized configuration and DNS-based routing.
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: 6 findings, up to high
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 →
- high Supply Chain · line 84 Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
- high Tool Misuse · line 84 Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.
- medium Privilege Escalation · line 84 Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.
- medium Rogue Agent · line 97 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Rogue Agent · line 413 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Excessive Agency · line 503 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00030 | $0.05668 |
| Opus 5 | $0.00015 | $0.02834 |
| Sonnet 5 | $0.00006 | $0.01134 |
| Haiku 4.5 | $0.00003 | $0.00567 |
Grade D, and why
nacos-skill-registry scanned grade D with 3 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 11d 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.

Nacos Skill Registry
This skill helps you discover, install, update, merge, and publish AI skills through Nacos using the nacos-cli tool.
When to Use This Skill
Use this skill when the user:
- Asks "how do I do X" where X might be a task with an existing skill in Nacos
- Says "find a skill for X" or "is there a skill in Nacos for X"
- Asks "what skills are available" or "list skills from Nacos"
- Wants to search for tools, templates, or workflows stored in Nacos
- Needs to download or install a skill from a personal, team, or organization Nacos registry
- Wants to upload or publish a local skill to Nacos for reuse
- Mentions sharing skills across agents, machines, teammates, or execution environments
- Needs to merge local skill edits with a newer remote version and publish the merged result
What is nacos-cli?
The nacos-cli is a command-line tool for interacting with Nacos. It supports configuration management, skill management, agent spec management, and provides an interactive terminal.

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.

nacos-skill-registry is a skill published in the GitHub repository alibaba/nacos (33,359 stars, last pushed today), licensed Apache-2.0. It adds 30 tokens to every session and 5,668 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
