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 | $0.00188 | $0.00188 |
| Opus 5.5 | $0.00075 | $0.00075 |
| Sonnet 5.5 | $0.00038 | $0.00038 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
altinity-skills AGENTS.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
ClickHouse connectivity
Follow the altinity-expert-clickhouse-connection skill. In short:
- MCP mode (preferred): use a tool whose name contains
clickhouseand one ofquery/execute/sql(the exact name depends on the harness, e.g.clickhouse_execute_queryin OpenCode,mcp__clickhouse__execute_queryin Claude Code). One SQL statement per call. - Exec mode:
clickhouse-clientwith the connection flags the user provided. One statement per invocation; never--queries-fileor--multiquery.
Probe with select hostName(), version().
If the probe fails:
- Stop immediately (do not proceed with audit queries and don't try to write scripts).
- Ask for the missing connection context (target host/cluster, mode, credentials/profile), or return a clear failure.
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.

altinity-skills AGENTS.md is an instructions file published in the GitHub repository Altinity/altinity-skills (17 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 188 tokens to every session, about $0.0008 per session on Opus 5.5. A static security scan graded it A with 0 findings.
