slfg

slfg is a command for Claude Code from tajmahal226/compound-engineering-plugin. It costs 13 tokens per session (320 once invoked), scanned A, a copy of slfg, MIT.

A command that runs a full software-engineering workflow with multiple AI agents working in parallel on planned tasks, reviews, tests, and follow-up fixes.

In plain words
What is it for?
Use it to plan and build a feature, run review and browser tests concurrently, resolve findings, and record the finished work for a pull request.
Why use it?
It coordinates the stages of a larger change so implementation, review, browser testing, TODO resolution, and a final walkthrough happen in a defined sequence.

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

slfg 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 6d 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

88% identical to slfg — 10 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 it actually says

Swarm-enabled LFG. Run these steps in order, parallelizing where indicated. Do not stop between steps — complete every step through to the end.

Sequential Phase

  1. Optional: If the ralph-wiggum skill is available, run /ralph-wiggum:ralph-loop "finish all slash commands" --completion-promise "DONE". If not available or it fails, skip and continue to step 2 immediately.
  2. /ce:plan $ARGUMENTS
  3. /compound-engineering:deepen-plan
  4. /ce:workUse swarm mode: Make a Task list and launch an army of agent swarm subagents to build the plan

Parallel Phase

After work completes, launch steps 5 and 6 as parallel swarm agents (both only need code to be written):

  1. /ce:review — spawn as background Task agent
  2. /compound-engineering:test-browser — spawn as background Task agent

Wait for both to complete before continuing.

Finalize Phase

  1. /compound-engineering:resolve_todo_parallel — resolve any findings from the review
  2. /compound-engineering:feature-video — record the final walkthrough and add to PR
  3. Output <promise>DONE</promise> when video is in PR

Start with step 1 now.

Changes

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.
