What it does

Rlm is an agent skill from BowTiedSwan/rlm-skill. Process large codebases (100 files) using the Recursive Language Model pattern. Treats code as an external environment, using parallel background agents to map-reduce complex tasks without context rot.

Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `README.md`, `install.sh` and `rlm.py`).

It sits in Agent Workflows, covering Context engineering. It works with Python.

When your agent uses it

  • Tasks that involve Context engineering

Example prompts

  • “/rlm”

Requirements

  • Python 3
  • A Bash shell

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Choose Your Engine
  2. Index & Filter (The "Peeking" Phase)
  3. Parallel Map (The "Sub-Query" Phase)
  4. Reduce & Synthesize (The "Aggregation" Phase)

What it can do on your machine

Read from SKILL.md and the folder at commit 6673b5d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    Ships script files (Shell and Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Rlm loads about 928 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 446 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~928

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.

Safety

Auto-check passed

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 446 words (~928 tokens).

“"Context is an external resource, not a local variable."”
