flow: Instructions file for Claude Code

AGENTS.md

flow AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from Facets-cloud/flow. It costs 1,791 tokens per session, scanned B, original, MIT.

Project instructions for flow, a Go command-line tool that manages personal tasks and starts Claude Code sessions for those tasks. They describe its structure, build commands, tests, and mocked external dependencies.

In plain words
What is it for?
Use them when building, testing, or changing flow, including task commands, SQLite storage, and its session integrations.
Why use it?
They give a coding agent the repository's expected commands and boundaries, reducing mistakes such as touching real user data during tests.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: SessionStart hook event, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is Facets-cloud/flow's own configuration. It tells Claude Code, Codex and OpenCode how to work on flow itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything flow configures →

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 B, and why

flow AGENTS.md scanned grade B with 1 finding 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- `hookCommand` (SessionStart) and `userPromptSubmitHookCommand` (UserPromptSubmit) in `internal/app/skill.go` are the exact strings matched in `~/.claude/settings.json`. Changing either orphans existing installations.

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

flow — repo conventions

What this is

A Go CLI (flow) that manages personal tasks and bootstraps per-task Claude Code sessions. SQLite via modernc.org/sqlite (pure Go, no CGO).

Build and test

# Build (produces ./flow in the repo dir, which is on PATH)
make build
# or: go build -o flow .

# Full install (build + PATH + init + skill + hook)
make install

# Run all tests (fast — no network, no real iTerm/Claude)
make test
# or: go test ./...

# Run a single test
go test -run TestE2EFullRoundtrip -v ./internal/app/

Tests use $FLOW_ROOT pointed at a temp directory and override $HOME so nothing touches real ~/.flow/ or ~/.claude/. External dependencies (osascript, claude CLI) are mocked via package-level function vars.

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.

flow AGENTS.md is an instructions file published in the GitHub repository Facets-cloud/flow (99 stars, last pushed yesterday), licensed MIT. It adds 1,791 tokens to every session, about $0.0072 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-22.
