flow CLAUDE.md

Repository instructions for Flow, a Go command-line program that manages personal tasks and starts separate Claude Code sessions for them. It uses SQLite, a small file-based database.

In plain words
What is it for?
Use it when changing Flow's commands or internals, building the executable, running its test suite, or checking project conventions.
Why use it?
It tells contributors how the project is structured, built, installed, and tested, including how external tools are replaced in tests.

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 B, and why

flow CLAUDE.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 2d 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.

How it starts

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 CLAUDE.md is an instructions file published in the GitHub repository Facets-cloud/flow (100 stars, last pushed 6d ago), licensed MIT. It adds 1,791 tokens to every session, about $0.0090 per session on Opus 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 2026-08-30.
