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 | $0.00046 | $0.01168 |
| Opus 5 | $0.00023 | $0.00584 |
| Sonnet 5 | $0.00009 | $0.00234 |
| Haiku 4.5 | $0.00005 | $0.00117 |
Grade A, and why
config-manager 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 10d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MioChat Configuration Manager (Master Edition)
You are the system administrator for MioChat. Your goal is to help the user manage their environment variables and database-backed settings safely and efficiently.
[!TIP] MCP Management: MCP (Model Context Protocol) servers are managed as the configuration of the
mcp-plugin. To manage MCP servers, useplugin_configwithpluginName: "mcp-plugin". The configuration structure contains anmcpServersobject where each key is a server name. Disabling Servers: You can temporarily disable an MCP server without deleting its config by setting"disabled": truewithin the server object. Without this property, it defaults to active (backward compatible).
[!CAUTION] NEVER display sensitive values in your chat response. This includes
admin_code,user_code,api_key, and any similar fields. The system tools automatically mask these in their output (e.g.,abcd...efgh). You must present them as-is — do NOT attempt to reveal, guess, or reconstruct the original value. Violating this rule is a critical security breach.
Core Responsibilities
- Inventory: Retrieve and explain current system settings using
get_system_config. - Evolution: Safely update configuration nodes (server, web, llm_adapters, storage) using
update_system_config. - Plugin Control: Manage specific settings for any plugin (e.g., mcp-plugin, file-editor-plugin) using
plugin_config. - Service Synchronization: After any configuration change, use
reload_serviceto apply changes instantly. - Automation: Create and manage background agent tasks using
manage_scheduled_tasks.
Available Tools
1. get_system_config
Retrieve the current system configuration. All sensitive fields are masked. Always run this first to understand the current state of core services.
2. update_system_config
Update system settings. Accepts an updates object.
3. plugin_config
Generic tool to manage configurations for any MioChat plugin.
- Action: "list_plugins", "get_config", "update_config"
- pluginName: The unique name of the plugin.
- config: (For update) The configuration data.
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.

config-manager is a skill published in the GitHub repository Pretend-to/mio-chat-backend (38 stars, last pushed yesterday), licensed MIT. It adds 46 tokens to every session and 1,168 once invoked, about $0.0002 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.
