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 | $0.00082 | $0.00556 |
| Opus 5 | $0.00041 | $0.00278 |
| Sonnet 5 | $0.00016 | $0.00111 |
| Haiku 4.5 | $0.00008 | $0.00056 |
Grade A, and why
scienceworld-temperature-measurer 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.

Skill: Temperature Measurement for Scientific Experiments
Purpose
Measure the temperature of a target substance (e.g., a metal like lead) to determine if it has reached a specific state-change threshold, such as its melting point.
Core Workflow
- Acquire Thermometer: Ensure a thermometer is in your inventory. If not, locate and pick one up.
- Locate Target Substance: Identify the substance to be measured (e.g., "lead"). It may be in a container.
- Prepare for Heating (If Necessary): If measuring a melting point, the substance likely needs to be heated.
- Transfer the substance to a heat-resistant container (e.g., a metal pot).
- Move the container to a heating device (e.g., a blast furnace in the foundry).
- Activate the heating device.
- Measure Temperature: Use the thermometer from your inventory on the target substance.
- Interpret Result: The observation will state the measured temperature in degrees Celsius. Use this value to make a decision (e.g., "above 150.0 degrees" -> focus on the red box).
Key Actions & Observations
pick up thermometer: Acquire the essential measuring tool.move [substance] to [container]: Prepare the sample.activate [heating device]: Initiate the temperature change process.use thermometer in inventory on [substance]: The primary measurement command. The observation (the thermometer measures a temperature of X degrees celsius) is the skill's key output.- Observe state changes:
a substance called lead->a substance called liquid lead.
Bundled Logic
For a standard melting point determination task, use the bundled script measure_melting_point.py. It encapsulates the precise sequence for the lead experiment demonstrated in the trajectory.
Notes
- The skill assumes containers are open and accessible.
- Teleportation (
teleport to [room]) is often necessary to move between resource locations (e.g., kitchen, foundry). - If
use thermometerfails, check the substance's state vialook at [container]and ensure the thermometer is in your inventory.
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-temperature-measurer is a skill published in the GitHub repository zjunlp/SkillNet (1,255 stars, last pushed today), licensed MIT. It adds 82 tokens to every session and 556 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.
