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 | $0.07851 | $0.07851 |
| Opus 5.5 | $0.03140 | $0.03140 |
| Sonnet 5.5 | $0.01570 | $0.01570 |
| Haiku 4.5 | $0.00785 | $0.00785 |
Grade A, and why
daimonos AGENTS.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 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.

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

AGENTS.md
Cross-tool guidance for AI coding agents working in this repository.
Quick start (new agents)
Do these in order. Do NOT skip to reading source code.
- Read this file fully — project context, repo layout, conventions.
- Go to Vikunja first. Use the Vikunja MCP tools to read the daimonos
projects — see Vikunja projects for the id map. This is
the authoritative source for what's been done, what's in progress, and what's
planned. Most active work lives in project 183 (
daimonos-agent). Understand the project state before touching the codebase. - Check
.cursor/rules/— scoped rule files (bounded collections, configurable limits, env inheritance, no thread-spawn in callbacks, resource lifecycle, full-lifecycle tests, repowise). - Check
.cursor/strategies/— Rust collection patterns, memory-safety checklist, testing strategies. - Check
docs/for technical specs, anddocs/adr/for the accepted architecture decision records. - Only then read source code as needed for your specific task.
Daimonos tool usage policy
For repository/workspace operations in this project, use the daimonos MCP server tools by default. This includes file reads/writes, search, exec, git, cargo, docker, snapshots, and workspace introspection.
- Prefer
execute_scriptwhen a task needs 2+ daimonos tool calls. - Use single daimonos tools only for one-off operations.
- Use non-daimonos tools only when the target system is external to the workspace (for example Vikunja, GitHub, Atlassian, or web search).
Note: The workspace is the default base for relative paths and the trigram search index. It is not a filesystem boundary — daimonos can read, write, and exec any path on the system. There is no confinement.
What is Daimonos?
Daimonos is a bare-metal operating system purpose-built for AI agents. The kernel, filesystem, process model, and syscall interface are designed from the ground up for agent workloads — no shell, no terminal, no human-facing interfaces.
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.

daimonos AGENTS.md is an instructions file published in the GitHub repository beardfaceguy/daimonos (3 stars, last pushed today), licensed MIT. It adds 7,851 tokens to every session, about $0.0314 per session on Opus 5.5. 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.
