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 5.1 | $0.00011 | $0.00942 |
| Opus 5 | $0.00005 | $0.00471 |
| Sonnet 5 | $0.00002 | $0.00188 |
| Haiku 4.5 | $0.00001 | $0.00094 |
Grade A, and why
mags-init 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MAGS Init
Initialize the Memory And Guidance System for this project.
Steps
1. Check existing state
Check if a docs/ directory already exists in the project root. Also check for .mags/ directory and any existing CLAUDE.md.
Use Glob to scan for docs/**/*.md and check for .mags/config.yaml.
2A. If docs/ exists — Index existing documentation
Report what was found:
- Number of documents in docs/
- List the top-level structure
Call mags_list_docs to see if MAGS already has indexed documents. If not, read each markdown file in docs/ and call mags_create_doc to index them into MAGS.
Tell the user: "Found existing docs/ directory with N documents. Indexed into MAGS."
2B. If docs/ does not exist — Gather project info
Ask the user these questions (all at once, not one by one):
- What is this project? (brief description)
- What is the tech stack?
- What is the current state? (new, in progress, mature)
- What is the architecture type? (monolith, microservices, library, cli, mobile, serverless)
- What language should documentation be in? (en, tr, or other locale)
Call mags_detect_stack to auto-detect the project's tech stack. Use this information to enrich the docs.
Then create the docs/ directory structure using mags_create_doc with these templates. Pass the user's chosen locale (from question 5) as the locale parameter to each mags_create_doc call:
docs/architecture/overview.md— Project overview from user answersdocs/architecture/tech-stack.md— Tech stack detailsdocs/rules/coding-standards.md— Basic coding standards for the stackdocs/changelog/changes.md— Empty changelog
Stop here and wait for user answers before creating docs.
3. Create .mags/ directory
Create the following structure:
.mags/
config.yaml — MAGS configuration
config.yaml content:
version: 1
project_root: .
docs_path: docs/
locale: <user's chosen locale from question 5, e.g. "en" or "tr">
initialized_at: <current ISO date>
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.

mags-init is a skill published in the GitHub repository doancan/mags (3 stars, last pushed 7mo ago), licensed MIT. It adds 11 tokens to every session and 942 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
