moflo: Instructions file for Claude Code

CLAUDE.md

moflo CLAUDE.md is an instructions file for Claude Code from eric-cielo/moflo. It costs 4,484 tokens per session, scanned B, original, MIT.

Project instructions for moflo, an AI-agent orchestration tool that coordinates coding tasks through smaller work units and checks.

In plain words
What is it for?
Use them when changing moflo's command-line tools, source code, scripts, or packaged files, especially when checking paths, file systems, line endings, and shell commands.
Why use it?
They help keep changes consistent across Windows, macOS, and Linux while avoiding unsafe bulk retrieval and project-name leaks.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions subagents; mentions Claude Code.

This is eric-cielo/moflo's own configuration. It tells Claude Code how to work on moflo 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 moflo configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/eric/Projects/<client>/code.

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

moflo CLAUDE.md scanned grade B with 2 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.

How it starts

The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠ Rule #1 — All shipped code MUST be cross-platform (Linux + macOS + Windows)

Hard requirement, no exceptions. Consumers run moflo on Windows dev boxes, macOS laptops, and Linux CI runners. Any code that ships in bin/, src/cli/, .claude/scripts/, or node_modules/moflo/ MUST work identically on all three. The smoke harness runs on all three CI platforms specifically to catch divergence.

Before any change, audit it against the cross-platform checklist:

  1. Paths — use path.join, path.sep, path.resolve. NEVER hardcode / or \. NEVER hardcode /tmp, /usr/local, C:\\Users, etc.
  2. Symlinks — POSIX has them; Windows mostly doesn't. If you compare two paths for identity, fs.realpathSync BOTH sides first (otherwise /var/folders/... ≠ /private/var/folders/... on macOS — see #1145).
  3. Case sensitivity — POSIX FS is case-sensitive; macOS APFS + Windows NTFS are case-insensitive by default. Don't write Foo.ts and foo.ts in the same directory.
  4. Line endings — files written by moflo MUST use platform-appropriate EOL or be marked text=auto in .gitattributes. Tests that hash file contents must normalize.
  5. Shell commands — bash/grep/sed/cat/find don't exist on Windows out of the box. Use Node primitives (fs, child_process with spawn not shell, Glob/Grep tools) instead of shelling out. If you MUST shell, branch on process.platform.
  6. Process introspection — tasklist/wmic/Get-CimInstance on Windows vs ps//proc/<pid>/cmdline on POSIX. See daemon-lock.ts:isDaemonProcess* for the right shape.
  7. Spawning daemons — Windows requires shell: true + quoted strings (Node 24 DEP0190); POSIX uses detached: true. See commands/daemon.ts:startBackgroundDaemon.
  8. Tempdir + Windows port reservations — os.tmpdir() is platform-correct; ports 49152-65535 are reserved on Windows (EACCES) — use 40000-44999 in tests.
  9. rm/cp/mkdir in spell bash steps — Windows lacks these on PATH. Use node -e with fs/os for file ops in cross-platform spells.

Verify before pushing — don't trust your local OS:

  • The smoke harness (harness/consumer-smoke/run.mjs) covers all three platforms in CI. Watch macOS + Ubuntu runs, not just Windows.
  • tests/system/ runs cross-platform; tests/bin/ has explicit Windows + POSIX branches.
  • If your local OS is Windows, mentally simulate the POSIX path (symlinks, case-sensitivity, missing tasklist). If POSIX, simulate Windows.

Concrete examples of what cross-platform misses look like in practice:

  • #1145 follow-up (this session) — normalizeProjectRoot didn't realpathSync → macOS daemon resolved /var/folders/... → /private/var/folders/... while client saw the unresolved path → identity check false-positived → smoke failed on macOS + Ubuntu, passed on Windows. Shipped because verification was Windows-only.
  • feedback_spell_bash_minimal_path.md — spell bash steps on Windows lack mkdir/rm/cp on PATH; use node -e with fs/os.
  • feedback_docker_sandbox_git_safe_directory.md — git config --global safe.directory gets overridden by bind-mounted .gitconfig; must use --system.

See feedback_cross_platform_mandatory.md (auto-memory) for the running list.

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.
