Repository instructions for Flock, a desktop application that lets people use different AI providers, tools, sandboxes, workflows, and browser or computer controls.

In plain words
What is it for?
Use them when developing the Rust backend or React desktop interface, running the application, selecting an AI provider, testing, linting, or making release builds.
Why use it?
They explain the Rust workspace, desktop interface, command-line modes, and separate build and test commands for each part.

About the project

Flock is a desktop application for visually designing and running teams of AI agents, with a Rust backend and Tauri and React interface. It is used to orchestrate agent workflows that can perform tasks such as handling files, running commands, browsing the web, and executing pipelines, and the catalogue entries extend its agent and workflow setup.

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

flock 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 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.

Origin

This is a copy

97% identical to flock AGENTS.md — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with 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.
