Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00042 | $0.01360 |
| Opus 5 | $0.00021 | $0.00680 |
| Sonnet 5 | $0.00008 | $0.00272 |
| Haiku 4.5 | $0.00004 | $0.00136 |
Grade B, and why
mt-master-module scanned grade B 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 2d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

MT-Master-Module: Project Overview Creator
"One document to represent your entire project."
This skill creates a comprehensive project overview document that serves as the entry point for understanding a project in the federated knowledge system.
When to Use
- User explicitly requests: "마스터 모듈 만들어줘", "create master module", "프로젝트 개요 만들어줘"
- Project is mature enough to summarize
- Preparing for KB federation (multiple projects sharing knowledge)
For publishing specific modules, use mt-publish instead.
Workflow
Phase 1: Gather Information
Read project context:
cat .claude/memory-context.md
cat CLAUDE.md
mmodule tree
Review key modules:
cat .memory/modules/projects/*/current.md
cat .memory/modules/projects/*/decisions.md
Check timeline for milestones:
mweek
mtoday
Phase 2: Create Master Module
Create module structure:
mmodule create master
This creates .memory/modules/master/ locally.
When published, the registry key automatically includes project name prefix
(e.g., memory-tool/master) to avoid collisions across projects.
Required files:
current.md- Project overview (main document)decisions.md- Architectural decisions summary
Phase 3: Write Content
Master module template (current.md):

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.

mt-master-module is a skill published in the GitHub repository hanyki111/memory_tool (11 stars, last pushed 7d ago), licensed MIT. It adds 42 tokens to every session and 1,360 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
