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 | $0.00066 | $0.00907 |
| Opus 5 | $0.00033 | $0.00453 |
| Sonnet 5 | $0.00013 | $0.00181 |
| Haiku 4.5 | $0.00007 | $0.00091 |
Grade A, and why
alfworld-object-locator 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 6d 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: Object Locator for ALFWorld
When to Use
Trigger this skill when:
- Your goal requires a specific object (e.g.,
knife,cellphone,apple) - The object is not in your inventory
- The current observation does not explicitly state the object's location
Core Workflow
1. Parse the Environment
Extract all visible receptacles from the observation text. Typical ALFWorld receptacles include:
- Surfaces: countertop, desk, dresser, bed, shelf, sidetable, coffeetable, diningtable
- Containers: drawer, cabinet, safe, fridge, microwave, garbagecan
- Appliances: sinkbasin, bathtub, stoveburner, toaster
2. Rank by Likelihood
Use common-sense reasoning to prioritize where the target object is most likely found:
| Object Type | High-Probability Receptacles |
|---|---|
| Kitchen items (knife, spatula, pan) | countertop, drawer, diningtable, stoveburner |
| Food (apple, potato, tomato, bread) | fridge, countertop, diningtable, microwave |
| Bathroom items (sponge, cloth, soap) | sinkbasin, bathtub, cart, shelf |
| Electronics (cellphone, laptop, remote) | desk, sidetable, dresser, bed, coffeetable |
| Stationery (pen, pencil, book) | desk, shelf, drawer, sidetable |
| Lighting (candle, desklamp) | sidetable, shelf, desk, dresser |
3. Navigate and Search
For each candidate receptacle (in priority order):
go to {receptacle}- Read the observation — does it mention the target object?
- YES:
take {object} from {receptacle}— object found - NO: If the receptacle is closed,
open {receptacle}and re-check - Still NO: Move to the next candidate receptacle
- YES:
4. Track Searched Locations
Maintain a list of already-searched receptacles to avoid revisiting them. If all high-probability locations are exhausted, expand the search to remaining receptacles.
Example
Task: "Clean the knife and put it in drawer." Observation: "You are in the middle of a room. Looking quickly around you, you see a countertop 1, a drawer 1, a drawer 2, a fridge 1, a sinkbasin 1, a stoveburner 1."
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.

alfworld-object-locator is a skill published in the GitHub repository zjunlp/SkillNet (1,253 stars, last pushed yesterday), licensed MIT. It adds 66 tokens to every session and 907 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 2026-08-30.
