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 | $0.00052 | $0.00454 |
| Opus 5 | $0.00026 | $0.00227 |
| Sonnet 5 | $0.00010 | $0.00091 |
| Haiku 4.5 | $0.00005 | $0.00045 |
Grade A, and why
roblox-performance-optimization 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 7d 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
Roblox Performance Optimization
Goal
Keep the experience smooth on lower-end phones. Favor measurable fixes over visual guesses.
Use The Scene Analysis Skill
When available, invoke rbx-scene-analysis before deep performance work. Use it to inspect rendering, memory, instance composition, unparented instances, and animation or audio asset usage.
MCP Workflow
- Confirm Studio state with
get_studio_state. - Use
search_game_treeandinspect_instanceto identify heavy hierarchies. - Use
execute_luaufor targeted counts, tag scans, memory snapshots, or property audits. - Use
screen_captureto preserve before/after visuals. - Playtest with
start_stop_playand checkget_console_output.
Optimization Targets
- Instance count and deeply nested hierarchies.
- Unanchored parts causing physics cost.
- Excessive constraints, touched events, or per-frame loops.
- Large textures, too many unique materials, and high-poly meshes.
- Particle emitters with high rate/lifetime combinations.
- Dynamic lights, shadows, post-processing, and expensive transparency.
- Scripts that connect events repeatedly or leave stale connections.
- Workspace content that should stream or load later.
Mobile Budget Habits
- Build the first area to be visually strong but technically cheap.
- Prefer fewer meaningful effects over many constant effects.
- Use Level of Detail thinking for distant props.
- Keep UI lightweight and avoid per-frame layout work.
- Test phones and tablet-like viewport sizes, not only desktop Studio.
Report Format
Return:
- Biggest performance risks.
- Evidence from scene analysis, instance inspection, console output, or captures.
- Fixes ranked by likely player impact.
- Verification steps and any tradeoffs.
Next
Confirm the gains on-device with roblox-mobile-playtest, and re-run roblox-playtest-qa to make sure nothing regressed.
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.

roblox-performance-optimization is a skill published in the GitHub repository AshExplained/roblox-skills (6 stars, last pushed 2mo ago), licensed MIT. It adds 52 tokens to every session and 454 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 2026-08-31.
