cobbler-modeTurn on Elves Cobbler Mode for the current Claude Code thread.
Cobbler Mode is an agent skill from aigorahub/elves. Turn on Elves Cobbler Mode for the current Claude Code thread. Use when the user types /cobbler-mode or asks to keep chatting with the Cobbler by default.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Autonomous multi-batch development skill for Claude Code and Codex. They work while you sleep. The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit fba17a3. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Cobbler Mode loads about 439 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 210 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

This is an Elves-managed Claude Code alias for /cobbler-mode.
Use the installed elves skill's ## Cobbler instructions as the source of truth. Cobbler is
Elves' default orchestration model. Cobbler Mode is the lowest-friction current-thread way to keep
follow-up prompts Cobbler-mediated after the user says "Cobbler Mode: on" and until the user says
"Cobbler Mode: off" or "leave Cobbler Mode."
For non-trivial tasks, use the main skill's harness loop: capability scan, route and medium selection,
context packet, execute agents/tools/skills, collect evidence, fit answer,
present/record, and reclassify when evidence changes the task.
Use route and medium selection before dispatch.
Default behavior while Cobbler Mode is active:
Recommendation, Why this fits, Strongest dissent, Risks,
Next move, and Confidence when synthesis is useful.Cobbler Mode is current-thread conversation state, not durable run state. It is not a daemon and must not require OpenRouter or any external provider key.

Cobbler Mode fits situations like: the user types /cobbler-mode; asks to keep chatting with the Cobbler by default.
Run `npx skills add aigorahub/elves --skill cobbler-mode -a claude-code`. Or copy the skill folder (aliases/claude/cobbler-mode in aigorahub/elves) into .claude/skills/cobbler-mode in your project. Claude Code loads it when a task matches its description.
Run `npx skills add aigorahub/elves --skill cobbler-mode -a codex`. Or copy the skill folder (aliases/claude/cobbler-mode in aigorahub/elves) into .agents/skills/cobbler-mode in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aigorahub/elves --skill cobbler-mode -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cobbler-mode, .gemini/skills/cobbler-mode, .github/skills/cobbler-mode and .opencode/skills/cobbler-mode in your project.
SKILL.md names no scripts, command-line tools or credentials: Cobbler Mode is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Cobbler Mode is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 439 tokens (SKILL.md is roughly 1.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Cobbler Mode: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 297k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
