⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 20, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
The skill is only a doc wrapper around a separate `coderlm` binary that ships via npm/pypi and is not installed by copying the skill, and its recursive runs also need a coding-agent CLI plus API keys, so the headline divide-and-conquer benefit could not be measured here. The one bundled feature I could run live, the bashrlm.sh guard, does truncate a 1892-char flood down to a 200-char head+tail preview as advertised. But its documented redirect-aware bypass is broken on macOS: `cat big > out.txt` wrote only 266 of 1892 chars with a TRUNCATED marker leaked into the saved file, because the check relies on Linux-only /proc/self/fd/1. Useful concept, but real setup friction and a data-corrupting bug on this platform.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

- Triggers reliably 5/5
- Output vs. baseline 4/10
- Docs & honesty 3/5
What Coderlm does
Wraps a coding-agent CLI (codex, gemini, or claude) in a recursive divide-and-conquer harness for tasks that span many files, and ships bashrlm context guards that auto-truncate high-output shell commands. Triggers when a task involves >10 files, exceeds a comfortable context window, or benefits from decomposition into sub-agents.
How to install Coderlm
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
Commands — how to trigger Coderlm
-
/coderlmTurns codex/gemini/claude into a recursive agent with bundled bash output truncation guard
It also activates on plain-language prompts like these:
-
This refactor spans over 15 files, break it into sub-agent tasks -
Run this codex task recursively and truncate the noisy bash output -
Divide and conquer this large migration across multiple agents
Frequently asked questions
- Is the Coderlm skill free?
- Yes. The skill itself is free from CyrusNuevoDia/coderlm. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Coderlm work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 20, 2026. Verdict: Tested · Didn't pass.

- How do I install Coderlm?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Coderlm with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
