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 | $0.01399 | $0.01399 |
| Opus 5 | $0.00700 | $0.00700 |
| Sonnet 5 | $0.00280 | $0.00280 |
| Haiku 4.5 | $0.00140 | $0.00140 |
Grade A, and why
fusebase-flow 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 today.
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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — Fusebase Flow portable bootstrap
This repository uses Fusebase Flow for lifecycle discipline and Fusebase CLI provider assets for runtime/domain guidance. The recovery-owned overlay below is the portable bootstrap for every agentic surface. Canonical rules live in FLOW_RULES.md; do not duplicate them here.
FuseBase Flow — workflow lifecycle overlay
Fusebase Flow owns the development lifecycle; existing Fusebase CLI runtime, MCP, SDK, provider, and project rules remain authoritative for their domains. Project-specific rules win on conflict. Full boundary map: docs/fusebase-cli-edition.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.

fusebase-flow AGENTS.md is an instructions file published in the GitHub repository fusebase-dev/fusebase-flow (9 stars, last pushed today), licensed MIT. It adds 1,399 tokens to every session, about $0.0070 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-08.
