PhyAgentOS-core is an agent framework for physical, or embodied, tasks in which software agents plan tool calls, observe what happened, and verify whether a real-world goal was achieved. It is intended for systems that operate physical agents through governed execution, recovery, evidence collection, and task-level verification. The catalogue add-ons provide workflows for working with this framework.
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.

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 | $0.00019 | $0.00368 |
| Opus 5.5 | $0.00008 | $0.00147 |
| Sonnet 5.5 | $0.00004 | $0.00074 |
| Haiku 4.5 | $0.00002 | $0.00037 |
Grade A, and why
clawhub 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 1mo 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.
This is a copy
88% identical to clawhub — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
ClawHub
Public skill registry for AI agents. Search by natural language (vector search).
When to use
Use this skill when the user asks any of:
- "find a skill for …"
- "search for skills"
- "install a skill"
- "what skills are available?"
- "update my skills"
Search
npx --yes clawhub@latest search "web scraping" --limit 5
Install
npx --yes clawhub@latest install <slug> --workdir ~/.PhyAgentOS/workspace
Replace <slug> with the skill name from search results. This places the skill into ~/.PhyAgentOS/workspace/skills/, where PhyAgentOS loads workspace skills from. Always include --workdir.
Update
npx --yes clawhub@latest update --all --workdir ~/.PhyAgentOS/workspace
List installed
npx --yes clawhub@latest list --workdir ~/.PhyAgentOS/workspace
Notes
- Requires Node.js (
npxcomes with it). - No API key needed for search and install.
- Login (
npx --yes clawhub@latest login) is only required for publishing. --workdir ~/.PhyAgentOS/workspaceis critical — without it, skills install to the current directory instead of the PhyAgentOS workspace.- After install, remind the user to start a new session to load the skill.
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.
