# Fractal A fractal is a tree of autonomous agent loops, each in its own git worktree. A node iterates toward a goal and can spawn child nodes that work subtasks in parallel. This skill configures a node with the user, then launches it in tmux or a detached headless process group; from there it runs autonomously — iterating, committing, and spawning children as needed. Your role does not end at launch. The user (root) node has no loop of its own — **you are it.** Once a node is running you are its *operator*: you watch the tree, steer it, and relay between it and the user on their behalf. See **Operator** below. ## Directive `$ARGUMENTS` is a natural-language directive describing what this fractal should do. Interpret it: distill the node's goal, and map anything the user pinned down (a name, a budget, a model, limits, ...) onto the parameters below, each of which becomes the matching `fractal node init` flag. The `/fractal` skill routes all the configuration to `fractal node init` and passes only `--headless` (when tmux is unavailable or the directive asks for it) and `--continue`/`--clean`/`--drain` (when the directive asks to continue an existing node) to `fractal node start` — plus `--max-cost` when it accompanies a continue (a continue re-arms the cap at start, not init). **Parameters** — all configuration. Set by `fractal node init`, written to `config.json`, and editable there before launch:

Orca Replay

Answers questions about a past agent run from its recording rather than from memory, and replays or forks that run. Use when asked why an earlier run did something, or to reproduce a failure.
Fable Mode
881mrtooher/fable-mode
Enforces staged execution discipline on large tasks: a written stage plan, parallel delegation where the runtime supports it, a failable verification check at each stage, and a skeptical self-review before delivery. Trigger when the user explicitly asks OR when the task objectively spans multiple files, sources, or sessions. Do NOT trigger on ordinary multi-step requests that a direct attempt handles fine (autonomous triggering only; explicit invocation always runs).
Manus

Delegate complex, long-running tasks to Manus AI agent for autonomous execution. Use when user says 'use manus', 'delegate to manus', 'send to manus', 'have manus do', 'ask manus', 'check manus sessions', or when tasks require deep web research, market analysis, product comparisons, stock analysis, competitive research, document generation, data analysis, or multi-step workflows that benefit from autonomous agent execution with parallel processing.
