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.

What it costs to keep this loaded
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 | $0.00042 | $0.02758 |
| Opus 5 | $0.00021 | $0.01379 |
| Sonnet 5 | $0.00008 | $0.00552 |
| Haiku 4.5 | $0.00004 | $0.00276 |
Grade A, and why
materialreacttable-mastery 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 9d 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.

Material React Table Mastery
Build production-grade data tables w/ MRT V3 (TanStack Table V8 + MUI).
Maintenance status (June 2026): MRT V3 is still the latest major, but the last npm release (3.2.1) shipped March 2025 — the project is effectively dormant. MUI is now at v9 (latest-v7 = 7.3.x) while MRT officially pairs w/ MUI v6; v7+ support is tracked in open issue #1401 (no resolution). For NEW projects, weigh this lock-in; for existing ones, pin
@mui/[email protected].
When to Use
- Building data tables with MUI styling
- Server-side pagination/filtering/sorting
- CRUD editing (inline, modal, cell, table)
- Large dataset virtualization (10k+ rows)
- Complex filtering (date range, multi-select, faceted)
- Migrating between MRT versions (V1→V2→V3)
- MUI v7 compatibility issues

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.
