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 | $0.09169 | $0.09169 |
| Opus 5.5 | $0.03668 | $0.03668 |
| Sonnet 5.5 | $0.01834 | $0.01834 |
| Haiku 4.5 | $0.00917 | $0.00917 |
Grade A, and why
holocron 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 13d 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.
How it starts
The opening of the file, as written. The whole thing — 983 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Holocron Project Rules
This file is the single source of truth for all project rules, conventions, and policies. This file is the directory system prompt.
Network Continuity (Non-negotiable)
Never disconnect the agent, host, simulator, or test device from the internet. Do not disable Wi-Fi, change network settings, toggle interfaces, or use network disruption as a test technique unless the user explicitly authorizes that exact action for a one-off run.
Secret index
This is a value-free index. Never put secret values, tokens, passwords, or private keys in
AGENTS.md, source code, commits, or review artifacts.
Canonical local sources
.env— operator-local environment file; ignored by Git. Gate and restore commands must load it explicitly when live credentials are intended:set -a; source .env; set +a.services/platform/config/secrets.yaml— ignored application/operator secret store. Prefer an explicitHOLOCRON_SECRETS_PATHorHOLO_SECRETS_PATHwhen running from a worktree..env.exampleandservices/platform/config/secrets.example.yaml— templates only; they contain names/placeholders, not live credentials..tmp/**/restore-target.env— generated ephemeral restore credentials; treat as sensitive and do not use as a substitute for the operator's live restore tuple unless the task explicitly requires it.

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.
