Saiku is an open-source semantic layer that represents data as analytical cubes for browser exploration, SQL queries, dashboards, and AI-agent access. It is for analysts and applications that need to query structured business data through Mondrian, Apache Calcite, REST, or MCP. The catalogue instruction helps agents work with Saiku.

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 | $0.00089 | $0.00089 |
| Opus 5.5 | $0.00036 | $0.00036 |
| Sonnet 5.5 | $0.00018 | $0.00018 |
| Haiku 4.5 | $0.00009 | $0.00009 |
Grade A, and why
saiku 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 1mo 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.

What it actually says
CLAUDE.md
Project guidance for Claude Code lives in AGENTS.md, shared with every other coding agent, and is imported below. Edit AGENTS.md, not this file.

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.

saiku CLAUDE.md is an instructions file published in the GitHub repository spiculedata/saiku (1,334 stars, last pushed yesterday), licensed Apache-2.0. It adds 89 tokens to every session, about $0.0004 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 2026-08-30.
