What it does
Agent Mode is an agent skill from PhyAgentOS/PhyAgentOS-core. Unified tool for managing agent LLM modes (add, remove, update, list, switch).
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with OpenAI and Qwen. The repository describes itself as: PhyAgentOS is a Recursive Self-Improving (RSI) physical agent operating system that enables agents to recursively self-improve through agentic workflows. The licence is MIT.
Example prompts
- “/agent-mode”
What it can do on your machine
Read from SKILL.md and the folder at commit 466e38b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Agent Mode loads about 711 tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 239 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

When users want to manage agent modes:
- "List all available models" → Call
agent_modewithmethod: "list" - "Switch to coding mode" → Call
agent_modewithmethod: "switch",mode: "coding" - "Add a new model" → Call
agent_modewithmethod: "add",mode: "xxx",model: "xxx",describe: "xxx" - "Remove a model" → Call
agent_modewithmethod: "remove",mode: "xxx" - "Update a model" → Call
agent_modewithmethod: "update",mode: "xxx",model: "xxx",describe: "xxx"
Always use tool to manage agent modes, do not think by you self!
