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 | $0.02775 | $0.02775 |
| Opus 5.5 | $0.01110 | $0.01110 |
| Sonnet 5.5 | $0.00555 | $0.00555 |
| Haiku 4.5 | $0.00278 | $0.00278 |
Grade A, and why
nanoflash CLAUDE.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 1mo 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 — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NanoFlash
Personal Gemini agent harness. See README.md for philosophy and setup.
Quick Context
Single Node.js process with skill-based channel system. Channels (WhatsApp, Telegram, Slack, Discord, Gmail) are skills that self-register at startup. Messages route to a Gemini agent loop running in containers (Linux VMs). Each group has isolated filesystem and memory.
Architecture
User message → Channel (Telegram/WhatsApp/etc.)
→ SQLite (store message)
→ Polling loop (src/index.ts, every 2s)
→ container-runner.ts spawns Apple Container / Docker
→ agent-runner (container/agent-runner/src/index.ts)
→ Gemini API with tool loop
→ stdout: NANOFLASH_OUTPUT_START/END markers
→ Host parses output, sends response via channel
→ IPC files for side-effects (messages, reactions, tasks)
Two-process boundary: The host process (src/) manages channels, DB, IPC, and container lifecycle. The agent process (container/agent-runner/) runs inside a Linux container with only mounted directories visible. These communicate via stdin/stdout (initial prompt + output markers) and filesystem IPC (/workspace/ipc/).

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.

nanoflash CLAUDE.md is an instructions file published in the GitHub repository refactornator/nanoflash (5 stars, last pushed 6mo ago), licensed MIT. It adds 2,775 tokens to every session, about $0.0111 per session on Opus 5.5. 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 2026-08-31.
