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 | $0.03935 | $0.03935 |
| Opus 5.5 | $0.01574 | $0.01574 |
| Sonnet 5.5 | $0.00787 | $0.00787 |
| Haiku 4.5 | $0.00394 | $0.00394 |
Grade C, and why
dbrain CLAUDE.md scanned grade C with 3 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 2mo 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- `~/.claude/settings.json` — Tool permissions Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.
- **Permissions in `~/.claude/settings.json`** — Use `"mcp__dbrain__*"` wildcard to allow all tools globally without per-project prompts. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

dbrain
Your distributed mind. Wherever you go, I remember.
What is it
dbrain is a brain for your AIs. It stores who they are, who you are, and everything you've done together. Install it once, and every AI you use — at home, at work, on mobile — connects to the same brain. Same identity, same memories, same knowledge. No matter where you are.

Architecture
The brain has 4 layers:
- Identity — Who am I? Who are you? How should I behave? Stored in
documents. Every AI reads this first when it connects. One identity, many machines. - Conversations — Raw chat history from every AI session. Every message pair (user <-> assistant) gets stored. The brain remembers every conversation, from every machine.
- Knowledge — Structured facts organized by PARA (Projects/Areas/Resources/Archives). Typed entities (person, project, event, system). Hot/warm/cold tiers by access frequency. Memories that matter stay hot, the rest fades — like a real brain.
- Recall — Full-text search (FTS5) over all facts. Ask a question, get the memory.
Optional: with an LLM configured, dbrain periodically reviews unprocessed conversations and extracts facts into the knowledge layer. Like a brain consolidating memories during sleep.

Installation & Usage
Two-step process: init the brain (server), then connect clients.
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.

dbrain CLAUDE.md is an instructions file published in the GitHub repository ivncmp/dbrain (3 stars, last pushed 6mo ago), licensed MIT. It adds 3,935 tokens to every session, about $0.0157 per session on Opus 5.5. A static security scan graded it C with 3 findings (reads agent configuration directories, unrestricted tool access, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
