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 | $0.00062 | $0.00281 |
| Opus 5 | $0.00031 | $0.00140 |
| Sonnet 5 | $0.00012 | $0.00056 |
| Haiku 4.5 | $0.00006 | $0.00028 |
Grade A, and why
scienceworld-conditional-focus-executor 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 3d 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
Conditional Focus Executor
When to Use
Use after completing a measurement (temperature, pH, mass) when the task specifies a conditional rule like "If result > X, focus on A; otherwise, focus on B."
Procedure
- Evaluate the condition against your measurement result.
- Determine the target object based on which branch is true.
- Execute:
focus on <TARGET_OBJECT> - Verify: Confirm the focus action succeeded before proceeding.
If the focus action fails (e.g., object not found), use look around to verify the target object name matches exactly.
Example
Task: "If the temperature of the substance is above 50C, focus on the red box. Otherwise, focus on the blue box."
- Measurement result: 63C
- Evaluation: 63 > 50 is true → target is red box
- Execute:
focus on red box - Observation: "You focus on the red box." → task complete.
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-conditional-focus-executor is a skill published in the GitHub repository zjunlp/SkillNet (1,252 stars, last pushed 13d ago), licensed MIT. It adds 62 tokens to every session and 281 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.
