flfl

flfl is a skill for Claude Code, Codex from eric-cielo/moflo. It costs 23 tokens per session (1,087 once invoked), scanned A, original, MIT.

A ticket workflow that applies three project rules before researching, coding, testing, and reviewing a change. The rules cover cross-platform support, installing the library into another project, and keeping generated output out of source control.

In plain words
What is it for?
For handling GitHub tickets in projects that must work on Linux, macOS, and Windows, and that are distributed as libraries.
Why use it?
It helps prevent common problems that may only appear on another operating system or after the library is installed elsewhere. It keeps these checks active throughout the whole task.

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

flfl 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 5d 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.

The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

$ARGUMENTS

/flfl — /fl with moflo's standing considerations loaded first

Purpose: run the normal /fl ticket workflow, but seat the three things that break moflo changes before any research, code, or review happens — not after a reviewer catches them.

These are not a preamble to acknowledge and move past. Hold all three for the whole run: research, implementation, tests, /flo-simplify, /verify, and the PR body.

The three considerations

# Consideration What it changes about the work you are about to do
1 Rule #1 — everything ships cross-platform Linux, macOS and Windows, identically. Audit every edit for: path.join/path.sep over hardcoded separators; fs.realpathSync on both sides of any path comparison; no Foo.ts beside foo.ts; platform EOL; no bash/grep/sed/cat/find shell-outs (use Node fs/spawn); tasklist vs /proc for process checks; shell: true on Windows vs detached on POSIX when spawning; os.tmpdir() and test ports in 40000–44999. Verify against CI's macOS and Ubuntu runs, not just your own OS.
2 moflo is installed into a destination project This is a library, not an app. Before writing code, name (a) the consumer surface touched — bin/, src/cli/, .claude/scripts/, hooks, init/, settings/CLAUDE.md generators, anything synced into node_modules/moflo/; (b) the failure mode for someone already on the current version who upgrades — does their .moflo/ state still parse, do their hooks still wire, is a migration needed; (c) the round-trip cost — does this need publish-then-reinstall to take effect. If you cannot name all three, re-scope before writing code.
3 moflo dogfoods itself The daemon, hooks, statusline, MCP server and indexer all run from node_modules/moflo/…, not the source tree. A source edit changes nothing for those layers until publish + reinstall + Claude Code restart. Before diagnosing any "X is broken" symptom, establish which copy is actually running — diff bin/ against .claude/ against node_modules/moflo/ first. Expect local flapping: the session-start launcher re-syncs .claude/helpers/ from the installed package, so a local fix to a synced file reverts until published.

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.

flfl is a skill published in the GitHub repository eric-cielo/moflo (18 stars, last pushed yesterday), licensed MIT. It adds 23 tokens to every session and 1,087 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
