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 | $0.00142 | $0.01452 |
| Opus 5.5 | $0.00057 | $0.00581 |
| Sonnet 5.5 | $0.00028 | $0.00290 |
| Haiku 4.5 | $0.00014 | $0.00145 |
Grade A, and why
creativescope-store-charts 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.
How it starts
The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CreativeScope Store Charts
End-to-end workflow for answering "where is this game charting?" and "how has
its ranking changed over time?" using the two CreativeScope MCP store-ranking
tools. Load creativescope-best-practices first if you're not yet sure which
tool fits — this skill assumes the foundation layer.
Pick the right tool
| User intent | Tool |
|---|---|
| Which countries / categories / stores / rank types is a game charting on? | get_game_rank_markets |
| How has a game's chart position changed day-by-day in one market? | get_game_rank_trend (mode exact) |
| Best daily rank across ALL markets (winning market varies by day) | get_game_rank_trend (mode best, default) |
Never mix up store rankings (get_game_rank_*) with creative rankings
(get_creative_rankings) — they measure different things. See pitfall #1 in
creativescope-best-practices.
Workflow
-
Resolve the game's
game_id. This skill needs agame_id, not a free-text name. If you only have a name, usesearch_advertisersto look it up and pick the matchingadvertiser_id(==game_idin creative results). Confirm the result is the right game (publisher, store listings) before proceeding. -
Decide the question shape.
- "Where is it charting?" →
get_game_rank_markets - "How did it trend in one market?" →
get_game_rank_trendwithcountry+category(usemode: "exact") - "What's its best recent position across all markets?" →
get_game_rank_trenddefault (mode: "best")
- "Where is it charting?" →
-
Set the date window. Defaults are last 90 days; max 365 days. State the window you used.
-
Call the tool. Read the response carefully:
get_game_rank_markets: each item lists one (country, category, store, rank_type) combination withbest_rank,latest_rank, andranked_days_count. If the returned item count equals yourlimit, the list may be truncated — disclose "at response cap" in your answer.get_game_rank_trend: one series perrank_typeunderdata.series. A rank type the game is NOT charting on returnspoints: [],ranked_days: 0, and nobest_rank/latest_rankkeys at all. Absence of these keys is not an error — it means "not charting". Don't manufacture a flat line at rank 0.
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.

creativescope-store-charts is a skill published in the GitHub repository creativescope/creativescope-mcp (0 stars, last pushed 6d ago), licensed MIT. It adds 142 tokens to every session and 1,452 once invoked, about $0.0006 per session on Opus 5.5. 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 2026-10-14.
