Origin original No closer match found in the catalogue.
Token cost
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 | $0.00063 | $0.23689 |
| Opus 5 | $0.00032 | $0.11845 |
| Sonnet 5 | $0.00013 | $0.04738 |
| Haiku 4.5 | $0.00006 | $0.02369 |
Security
Grade A, and why
user-usecases 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 yesterday.
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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

APIbase — User Use Cases Database
This skill contains real-world use cases of API integrations on the APIbase platform. Each use case documents the full pipeline: client data → API analysis → wrapper creation → MCP tools → publication.
Use these examples as reference patterns when:
- Onboarding a new API provider
- Explaining the APIbase value proposition to partners
- Designing API wrappers for new categories
- Generating MCP Tool Definitions
- Writing AI-instructions for agents

Changes
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.

user-usecases is a skill published in the GitHub repository whiteknightonhorse/APIbase (10 stars, last pushed today), licensed MIT. It adds 63 tokens to every session and 23,689 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
