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.

What it costs to keep this loaded
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 | $0.00046 | $0.04279 |
| Opus 5 | $0.00023 | $0.02139 |
| Sonnet 5 | $0.00009 | $0.00856 |
| Haiku 4.5 | $0.00005 | $0.00428 |
Grade A, and why
revenuecat-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 13d 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.

Accessing RevenueCat charts
When querying a RevenueCat chart, follow this workflow:
- Use
get-chart-options-schemato discover a chart's available options. - Use
get-chart-datawith the right options to retrieve the chart data. - Analyze the data, using scripts for any non-trivial arithmetic.
Via the rc CLI (see the revenuecat-cli skill): rc charts list to list charts, rc charts options <chart> for the schema, and rc charts show <chart> for the data.
In general, to avoid clogging the context, start with defined timeframes and larger resolution, then narrow down.
1. Discover chart options with get-chart-options-schema
- Treat
get-chart-options-schemaas the source of truth for each chart before callingget-chart-data. It returns the chart's supportedresolutions,filters,segments, anduser_selectors. Always call this tool with"realtime": true. Laterget-chart-datacalls must use string IDs exactly as returned here. filtersare the dimensions you may later constrain inget-chart-data.- Each filter has:
- an
idto later use as the filtername. - a
value_modethat tells you how to choose valid values:inline_enummeans you must use theidof one of the returnedoptions. Resolve user-supplied names first with the matching list tool, such aslist-products,list-offerings,list-apps, etc.inferred_standardmeans use the standard code fromvalue_sourcesuch as an ISO country code.dynamicmeans values come from observed project data and must match exactly.
- an
- Do not pass display names, store product identifiers, bundle IDs, or guessed values unless the schema says they are valid values.
- Each filter has:
segmentsare the dimensions you may later group by inget-chart-datausingsegment.- A segment entry directly gives the dimension
idto use. It does not list segment values because the chart will group by it and show all values in the output. - Filters and segments are separate per-chart lists, so never assume a filterable dimension is
segmentable. For example,
conversion_to_payingmay supportproduct_idandoffering_identifieras filters but not as segments.
- A segment entry directly gives the dimension
user_selectorsare chart-specific switches that change what metric or window the chart returns. Each selector is keyed by the selector ID to pass inget-chart-data'sselectorsJSON object and usually includes allowed option IDs plus a default. For example, therevenuechart may userevenue_type(revenue,revenue_net_of_taxes,proceeds), while conversion charts may useconversion_timeframeand default to7_days. State non-default selector choices when presenting results.resolutionslist the supported time granularity and their string IDs forget-chart-data. You must always pass one of these resolution IDs (such as"0"for day or"2"for month) when later callingget-chart-data.
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.

revenuecat-charts is a skill published in the GitHub repository RevenueCat/ai-toolkit (65 stars, last pushed 11d ago), licensed MIT. It adds 46 tokens to every session and 4,279 once invoked, about $0.0002 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.
