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 | $0.00020 | $0.01026 |
| Opus 5 | $0.00010 | $0.00513 |
| Sonnet 5 | $0.00004 | $0.00205 |
| Haiku 4.5 | $0.00002 | $0.00103 |
Grade A, and why
mags-setup 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 4d 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 — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MAGS Setup
Analyze the current project and recommend an optimal setup for Claude Code workflows.
Steps
1. Analyze project
Gather project signals in parallel:
- Read
.mags/config.yamlto check for alocalefield. If present, use this locale value when callingmags_create_docandmags_scaffold_modulethroughout this flow. - Call
mags_project_summaryfor overall context. - Use
Globto detect project type:package.json— Node/JS projectCargo.toml— Rust projectgo.mod— Go projectpyproject.tomlorrequirements.txt— Python projectpom.xmlorbuild.gradle— Java project*.slnor*.csproj— .NET project
- Use
Globto detect frameworks and tools:next.config.*— Next.jsnest-cli.jsonorsrc/main.tswith NestJS imports — NestJSprisma/schema.prisma— Prisma ORMdocker-compose.*— Docker.github/workflows/— GitHub Actions CItailwind.config.*— Tailwind CSS
- Read
package.jsonor equivalent manifest for dependencies.
2. Recommend skills and agents
Based on the detected stack, recommend Claude Code slash commands and workflows. Present as a checklist:
== Recommended Setup for <project name> ==
Detected: <framework> + <language> + <key tools>
SKILLS (slash commands to install)
[x] /commit — You have this (from MAGS)
[ ] /review-pr — PR review automation
[ ] /test — Test generation for <framework>
[ ] /deploy — Deploy workflow for <detected CI>
HOOKS (automation triggers)
[ ] pre-commit — Lint + typecheck before commit
[ ] post-save — Auto-format on save
[ ] pre-push — Run tests before push
MCP SERVERS
[ ] mags — Already active
[ ] <db tool> — Database introspection for <detected DB>
[ ] <api tool> — API testing for <detected framework>
Mark items already present with [x]. Only recommend what makes sense for the detected stack.
3. Audit CLAUDE.md
Call mags_audit_claude_md to check the current CLAUDE.md (if it exists) against the project's actual state.
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-setup is a skill published in the GitHub repository doancan/mags (3 stars, last pushed 7mo ago), licensed MIT. It adds 20 tokens to every session and 1,026 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.
