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 | $0.01256 | $0.01256 |
| Opus 5 | $0.00628 | $0.00628 |
| Sonnet 5 | $0.00251 | $0.00251 |
| Haiku 4.5 | $0.00126 | $0.00126 |
Grade A, and why
game-install-size-optimization-agent-skill CLAUDE.md 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.
This is a copy
88% identical to game-mod-balance-scaling-agent-skill CLAUDE.md — 46 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Problem This Skill Solves
This skill provides a structured, evidence-backed analytical workflow for Game Asset Pipeline & Install-Size Optimization. It gathers authoritative real-time and reference data, applies recognized domain methods, cross-references academic research, and delivers actionable outputs that are fully evidenced, risk/limitation-disclosed, and traceable to authoritative sources — continuously self-improving through an automated knowledge crawl pipeline.
Harness Flow Summary
/game-install-size-optimization invoked
│
├─ Step 1: sub-gather-requirements → Clarify the object of analysis, constraints, timeframe, available inputs, target audience, and language before any data fetching.
├─ Step 2: sub-evidence-collector → Fetch authoritative real-time and reference data for the object: current status/parameters, authoritative documents/standards, and recent developments from domain and academic sources.
├─ Step 3: sub-core-analysis → Optimize game install size via asset compression, streaming, dedup, language-pack splitting, and delta patches, balancing size and quality.
├─ Step 4: sub-knowledge-updater → Query SECOND-KNOWLEDGE-BRAIN.md for authoritative academic and professional evidence; surface citations with tier labels and flag gaps for the crawl pipeline.
├─ Step 5: sub-advisor → Synthesize all prior analysis into a risk-disclosed conclusion with a full evidence chain and recommended actions.
└─ Step 6: main (quality gate) → verify evidence hierarchy, disclosure, output polish

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.
