massive-context-mcp: Skill for Claude Code

.claude/skills/rlm/SKILL.md

rlm is a skill for Claude Code from egoughnour/massive-context-mcp. It costs 0 tokens per session (2,825 once invoked), scanned A, a copy of rlm, MIT.

A method for working with files and collections of text that are too large for one AI request by splitting them into smaller pieces and combining the results.

In plain words
What is it for?
Use it to summarize large datasets, find patterns, count or filter information, and study the structure of a large codebase or document collection.
Why use it?
It prevents large files, many files, logs, reports, or research papers from exceeding the AI's context limit. It also makes broad codebase analysis possible when everything cannot be reviewed at once.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: positional $N argument; mentions Claude Code.

This is egoughnour/massive-context-mcp's own configuration. It tells Claude Code how to work on massive-context-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything massive-context-mcp configures →

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

rlm 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 2mo 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.

RLM (Recursive Language Model) Skill

Overview

The RLM pattern enables processing massive contexts (10M+ tokens) that exceed Claude's context window by recursively chunking, processing, and aggregating results. Instead of failing on large files, use RLM to break them into manageable pieces.

When to Use RLM

Use RLM when you encounter:

  • Large files: Any file >100KB or >2000 lines
  • Multi-file analysis: Processing multiple files together (combined size matters)
  • Context exceeded: User asks to analyze content that won't fit in context window
  • Aggregation tasks: Summarizing logs, finding patterns across large datasets, counting/filtering operations
  • Deep codebase analysis: Understanding architecture across many files
  • Document processing: Analyzing reports, research papers, documentation sets

Don't use RLM for:

  • Small files (<100KB)
  • Single-pass tasks that fit in context
  • Interactive editing (use standard tools)

The RLM Pattern

The core workflow is: Load → Inspect → Chunk → Sub-Query → Aggregate

Step 1: Load Context

# Load large content into RLM memory
rlm_load_context(
  name="codebase",
  content=file_contents  # Full file content
)

Returns: {name, size_bytes, size_chars, line_count, loaded: true}

Step 2: Inspect Context

# Understand structure without loading into prompt
rlm_inspect_context(
  name="codebase",
  preview_chars=500  # Optional preview
)

Returns: Metadata + preview (first N chars)

Step 3: Chunk Context

# Break into manageable pieces
rlm_chunk_context(
  name="codebase",
  strategy="lines",  # or "chars" or "paragraphs"
  size=100  # Lines per chunk (or chars if strategy=chars)
)

Chunking Strategies:

  • lines (default): Split by line count - best for code, logs, structured data
  • chars: Split by character count - best for prose, unstructured text
  • paragraphs: Split by blank lines - best for documents, markdown

Returns: {name, chunk_count, strategy, size_per_chunk}

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.

rlm is a skill published in the GitHub repository egoughnour/massive-context-mcp (1 stars, last pushed 9mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,825 tokens. A static security scan graded it A with 0 findings. It is 100% identical to rlm, differing in 0 lines, and is treated as a copy.
