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 | $0.06698 | $0.06698 |
| Opus 5.5 | $0.02679 | $0.02679 |
| Sonnet 5.5 | $0.01340 | $0.01340 |
| Haiku 4.5 | $0.00670 | $0.00670 |
Grade A, and why
kernel-claude CLAUDE.md 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 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.

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

94% identical to kernel-claude AGENTS.md — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 375 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Location: _meta/agentdb/agent.db Use concrete task nouns, library/subsystem names, discovered paths/symbols, and exact errors or desired outcomes. Recall again after repo inspection reveals better terms, when scope or hypothesis changes, and whenever a new failure appears.
Tier by reversibility × silence × blast radius. File count is only a weak hint. Ambiguous = assume higher tier. Recall from AgentDB at every tier. Implement inline by default; delegate to agents only when the work is heavy and file-disjoint, explicitly requested, or needs independent verification. IF tier >= 2: run /kernel:tearitapart before implementation.
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.
