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 | $0.00010 | $0.00405 |
| Opus 5 | $0.00005 | $0.00202 |
| Sonnet 5 | $0.00002 | $0.00081 |
| Haiku 4.5 | $0.00001 | $0.00040 |
Grade A, and why
mags-docs-validate 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.
What it actually says
MAGS Docs Validate
Run validation checks on all project documents.
Usage
/mags-docs-validate
Steps
-
Ask the user: "Standard validation or deep validation?"
- Standard — checks frontmatter, required sections, cross-references, freshness
- Deep — all standard checks plus: version conflict detection, memory-doc consistency, ADR structure validation, and module completeness checks
If deep: call
mags_validate_docswithdeep: true. If standard (or no preference): callmags_validate_docswith default parameters. -
Display results grouped by severity:
== Document Validation == Errors (must fix): - docs/architecture/overview.md: Missing required section "Tech Stack" - docs/rules/backend.md: Broken internal link to ../api/auth.md Warnings (should fix): - docs/modules/auth.md: No code examples found - docs/changelog/changes.md: Last updated over 30 days ago Passed: <N>/<total> documents are healthy -
If there are errors, ask: "Would you like me to fix the errors?"
-
If yes, read each problematic doc with
mags_get_doc, fix the issues, and callmags_update_doc.

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.
