Daem0n-MCP: Skill for Claude Code

.claude/skills/summon_daem0n/SKILL.md

summon-daem0n is a skill for Claude Code from 9thLevelSoftware/Daem0n-MCP. It costs 22 tokens per session (1,952 once invoked), scanned C, original, MIT.

A setup guide for Daem0n-MCP, a project memory system, across one repository or several related repositories. It explains how to initialize, link, combine, and verify project context.

In plain words
What is it for?
Use it to initialize Daem0n-MCP, connect client and server repositories, merge their stored project data, and inspect the resulting memory summary.
Why use it?
It removes uncertainty when a project is split into separate code repositories or needs shared memory. It also provides a way to confirm that the combined project context is available.

Skill for Claude Code

Written for Claude Code: PreToolUse hook event. Also seen: reads .claude/ paths; names the NotebookEdit tool.

This is 9thLevelSoftware/Daem0n-MCP's own configuration. It tells Claude Code how to work on Daem0n-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 Daem0n-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 C, and why

summon-daem0n scanned grade C with 1 finding 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 8d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Summoning the Daem0n

This skill guides Claude through setting up Daem0n-MCP for various project structures.

Single Repo Setup

For a single repository:

# Daem0n auto-initializes on first commune(action="briefing")
# Just ensure you're in the project root

Multi-Repo Setup (Client/Server Split)

When you have related repos that should share context:

Option A: Consolidated Parent (Recommended)

Best when repos are siblings under a common parent:

/repos/
├── backend/
└── client/

Steps:

  1. Navigate to parent directory

    cd /repos
    
  2. Initialize Daem0n in parent

    Call commune(action="briefing", project_path="/repos")
    
  3. If child repos already have .daem0nmcp data, consolidate:

    # Link the children first
    Call maintain(action="link_project", linked_path="/repos/backend", relationship="same-project")
    Call maintain(action="link_project", linked_path="/repos/client", relationship="same-project")
    
    # Merge their databases into parent
    Call maintain(action="consolidate", archive_sources=True)
    
  4. Verify consolidation

    Call commune(action="briefing", project_path="/repos")
    # Should show combined memory count
    

Option B: Linked but Separate

Best when repos need their own isolated histories but cross-awareness:

# In each repo, link to siblings
cd /repos/backend
Call maintain(action="link_project", linked_path="/repos/client", relationship="same-project")

cd /repos/client
Call maintain(action="link_project", linked_path="/repos/backend", relationship="same-project")

Then use include_linked=True on consult(action="recall") to span both.

Migrating Existing Setup

If you've been launching Claude from parent directory and have a "messy" .daem0nmcp:

  1. Backup existing data

    cp -r /repos/.daem0nmcp /repos/.daem0nmcp.backup
    
  2. Review what's there

    Call get_briefing(project_path="/repos")
    # Check statistics and recent decisions

What this file has done since we first saw it

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.

summon-daem0n is a skill published in the GitHub repository 9thLevelSoftware/Daem0n-MCP (73 stars, last pushed 29d ago), licensed MIT. It adds 22 tokens to every session and 1,952 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
