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 | $0.00071 | $0.00768 |
| Opus 5 | $0.00036 | $0.00384 |
| Sonnet 5 | $0.00014 | $0.00154 |
| Haiku 4.5 | $0.00007 | $0.00077 |
Grade A, and why
scienceworld-growth-focuser 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 11d 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: Growth Focuser
Purpose
Apply the focus on action to a specific biological entity (e.g., a planted seed or growing plant) to signal your intent to monitor its development. This action is often a prerequisite for the environment to process growth stages or trigger life cycle progression events.
When to Use
Use this skill when:
- After Planting: You have just placed a seed or seedling into a suitable growth medium (e.g., soil with water).
- Stage Monitoring: You need to check or trigger a progression in the plant's life cycle (e.g., from seed to sprout, sprout to mature plant, flowering, or reproduction).
- Intent Signaling: The task requires you to explicitly indicate which entity you are observing or nurturing.
Core Instruction
- Identify the Target: Locate the specific plant or seed you intend to focus on. Ensure it is in a valid state for growth (e.g., planted in soil with water).
- Execute Focus: Use the action:
focus on <PLANT_OBJECT> [in <CONTAINER>].- Replace
<PLANT_OBJECT>with the exact name of the biological entity (e.g.,avocado seed). - Use the optional
[in <CONTAINER>]clause if the object is inside another object (e.g.,avocado seed in flower pot 1). This is crucial for disambiguation.
- Replace
- Confirm & Wait: Upon successful focus, you will receive a confirmation. Biological growth requires time. Use
waitactions strategically after focusing to allow the simulated environment to process development stages.
Key Considerations
- Disambiguation: If multiple identical objects exist, the environment may prompt you to choose. Always specify the container (e.g.,
in flower pot 1) to avoid this. - Prerequisites: The
focus onaction typically follows preparatory steps liketeleport to <location>,pick up <item>, andmove <seed> to <pot>. - Patience is Required: Growth is not instantaneous. The
focus onaction signals intent, but you must follow it withwaitactions to observe results.
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-growth-focuser is a skill published in the GitHub repository zjunlp/SkillNet (1,256 stars, last pushed today), licensed MIT. It adds 71 tokens to every session and 768 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 2026-08-30.
