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 | $0.00236 | $0.00236 |
| Opus 5.5 | $0.00094 | $0.00094 |
| Sonnet 5.5 | $0.00047 | $0.00047 |
| Haiku 4.5 | $0.00024 | $0.00024 |
Grade A, and why
rhizome-mcp 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 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.
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
Agent Guidelines
Use the configured rhizome-mcp server as the source of truth for active work and durable decisions.
Workflow
Claim tracked work through the rhizome-mcp server before editing. Keep the returned lease token private and available until the attempt completes, renewing before expiry and saving restartable checkpoints. Finish every attempt with its truthful outcome, verification actually performed, and next steps.
See the agent workflow guide for the complete select/claim/execute/finish workflow.
Never write in_progress; it is derived from an active lease. Never maintain the backlog or implementation status in Markdown.
Read rhizome://guides/agent-workflow for the full workflow, rhizome://guides/issue-lifecycle for state rules, and rhizome://guides/multi-agent-handoff for recovery. Use the rhizome-task-workflow skill when executing tracked work.
Build and test commands are in README.md; implementation contracts are indexed by SPEC.md.
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.
