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.

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 | $0.00084 | $0.00710 |
| Opus 5 | $0.00042 | $0.00355 |
| Sonnet 5 | $0.00017 | $0.00142 |
| Haiku 4.5 | $0.00008 | $0.00071 |
Grade A, and why
scienceworld-liquid-source-finder 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 2d 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.

Skill: Liquid Source Finder
When to Use
Activate this skill when your primary task requires a liquid (e.g., water, juice, paint) and you have confirmed it is not present in your current inventory or immediate vicinity.
Core Procedure
- Initiate Search: If no liquid source is visible, begin a systematic room survey.
- Prioritize Rooms: Teleport to and survey rooms in this order of likelihood:
- Kitchen (high priority - contains sink, fridge, cups)
- Bathroom (high priority - contains sink, toilet, bathtub)
- Greenhouse (medium priority - contains sink, jugs)
- Workshop (medium priority - may contain specialized containers)
- Art Studio (low priority - may contain paint or water for cleaning)
- Living Room, Bedroom, Hallway (low priority - check for any containers)
- Survey Each Room:
- Use
look aroundupon arrival. - Visually scan the observation for liquid sources or containers that might hold liquid (e.g.,
sink,toilet,jug,cup,bathtub). - If a source is found (e.g., a
sink), proceed to obtain the liquid. If a container is found (e.g., ajug),examineit orlook atit to check its contents.
- Use
- Obtain the Liquid:
- If the liquid is in a portable container (e.g.,
cup containing water), simplypick upthe container. - If the liquid is in a fixed source (e.g.,
sink,toilet): a. Ensure you have an empty container in your inventory. If not, find one (e.g., acup). b.moveyour container to the source. c.activatethe source if necessary (e.g., turn on the sink). d.deactivatethe source once done. e.pick upthe now-filled container.
- If the liquid is in a portable container (e.g.,
- Terminate Search: Once the required liquid is successfully obtained and in your inventory, conclude the skill and return to the main task flow.
Key Principles
- Efficiency: Do not re-survey rooms unnecessarily. Keep mental note of rooms already visited.
- Container Management: Always ensure you have a suitable container before attempting to collect liquid from a non-portable source.
- Observation Parsing: Focus on object names and their described contents. Look for keywords like
water,juice, or the name of your target liquid, and objects likesink,toilet,jug.
What ships with it
2 files 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-liquid-source-finder is a skill published in the GitHub repository zjunlp/SkillNet (1,253 stars, last pushed yesterday), licensed MIT. It adds 84 tokens to every session and 710 once invoked, about $0.0004 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.
