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 | $0.00093 | $0.00500 |
| Opus 5 | $0.00046 | $0.00250 |
| Sonnet 5 | $0.00019 | $0.00100 |
| Haiku 4.5 | $0.00009 | $0.00050 |
Grade A, and why
apollo-kotlin scanned grade A with 1 finding 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says
Apollo Kotlin Guide
Apollo Kotlin is a strongly typed GraphQL client that generates Kotlin models from your GraphQL operations and schema, that can be used in Android, JVM, and Kotlin Multiplatform projects.
Process
Follow this process when adding or working with Apollo Kotlin:
- Confirm target platforms (Android, JVM, KMP), GraphQL endpoint(s), and how schemas are sourced.
- Configure Gradle and code generation, including custom scalars
- Create a shared
ApolloClientwith auth, logging, and caching. - Implement operations.
- Validate behavior with tests and error handling.
Reference Files
- Setup - Gradle plugin, schema download, codegen config (including scalars), client configuration (auth, logging, interceptors)
- Operations - Queries, mutations, subscriptions, and how to execute them
- Caching - Setup and use the normalized cache
Scripts
- list-apollo-kotlin-versions.sh - List versions of Apollo Kotlin
- list-apollo-kotlin-normalized-cache-versions.sh - List versions of the Apollo Kotlin Normalized Cache library
Key Rules
- Use Apollo Kotlin v4+, do not use v3 or older versions.
- Keep schema and operations in source control to make builds reproducible.
What ships with it
5 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.

apollo-kotlin is a skill published in the GitHub repository frogobox/frogo-sdk (21 stars, last pushed 6d ago), licensed Apache-2.0. It adds 93 tokens to every session and 500 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 92% identical to apollo-kotlin, differing in 5 lines, and is treated as a copy.
