SkillNet is infrastructure for finding, creating, evaluating, combining, and coordinating reusable capabilities for AI agents. Agent developers use it as a searchable and installable library of skills and as a system for selecting skills for particular tasks. The catalogue contains skills that can be discovered, installed, or used with SkillNet.
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 | $0.00062 | $0.00395 |
| Opus 5 | $0.00031 | $0.00198 |
| Sonnet 5 | $0.00012 | $0.00079 |
| Haiku 4.5 | $0.00006 | $0.00040 |
Grade A, and why
scienceworld-room-navigator 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 5d 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.
What it actually says
Instructions
Use this skill to instantly move the agent to a different room. This is the primary method of navigation.
When to Use
- The agent needs to find an object known to be in a specific room (e.g., "metal pot is located around the kitchen").
- The agent needs to access a facility available only in a specific room (e.g., a workshop for building circuits, a foundry for smelting).
- The agent has completed tasks in one room and needs to proceed to the next relevant location.
How to Use
- Identify the Target Room: Determine the exact name of the destination room from the task context or environment description (e.g.,
kitchen,workshop,foundry). - Execute Teleport: Use the
teleport to <ROOM_NAME>action. - Verify Arrival: The observation will confirm the teleport was successful (e.g., "You teleport to the kitchen."). You may then proceed with
look aroundto survey the new location.
Important Notes
- Teleportation is a single-step action. There is no need for intermediate movement.
- All standard room connections (doors) remain, but teleportation bypasses them.
- After teleporting, the agent's inventory and any held items remain unchanged.
Example
Task: Move to the kitchen to find a metal pot.
teleport to kitchen- Observation: "You teleport to the kitchen."
look aroundto survey the room and locate the metal pot.
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.

scienceworld-room-navigator is a skill published in the GitHub repository zjunlp/SkillNet (1,255 stars, last pushed today), licensed MIT. It adds 62 tokens to every session and 395 once invoked, about $0.0003 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 2026-09-03.
