nanoflash CLAUDE.md

nanoflash CLAUDE.md is an instructions file for coding agents from refactornator/nanoflash. It costs 2,775 tokens per session, scanned A, original, MIT.

Instructions for NanoFlash, a personal Gemini-based agent system that connects messaging channels to an isolated container. A container is a separated environment in which the agent runs with limited files and resources.

In plain words
What is it for?
Use it when understanding NanoFlash’s architecture, adding a messaging channel or tool, or locating the files responsible for routing, databases, containers, and inter-process communication.
Why use it?
It explains how messages move through the system and where channels, storage, agent execution, and side effects are handled.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

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.

Security

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 4d 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.

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/).

Key Files

File Purpose
src/index.ts Orchestrator: state, message loop, agent invocation
src/container-runner.ts Spawns agent containers, builds mounts and env vars, parses output markers
src/channels/registry.ts Channel registry (self-registration at startup)
src/ipc.ts IPC watcher: processes message/reaction/task files from containers
src/router.ts Formats messages as XML for the agent, strips <internal> tags on output
src/config.ts All configuration: trigger pattern, paths, intervals, Gemini models
src/gemini-media.ts Host-side media analysis — images inline, video/audio via Gemini File API (up to 2 GB)
src/task-scheduler.ts Runs scheduled tasks on cron/interval/once schedules
src/db.ts SQLite operations (messages, sessions, groups, tasks)
src/types.ts Channel interface, RegisteredGroup, NewMessage, etc.
groups/{name}/CLAUDE.md Per-group system instruction (loaded as Gemini systemInstruction)
container/agent-runner/src/index.ts The agent — Gemini tool loop, all tool implementations

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.
