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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.01952 |
| Opus 5 | $0.00011 | $0.00976 |
| Sonnet 5 | $0.00004 | $0.00390 |
| Haiku 4.5 | $0.00002 | $0.00195 |
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:
-
Navigate to parent directory
cd /repos -
Initialize Daem0n in parent
Call commune(action="briefing", project_path="/repos") -
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) -
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:
-
Backup existing data
cp -r /repos/.daem0nmcp /repos/.daem0nmcp.backup -
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.
