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 | $0.00000 | $0.00013 |
| Opus 5 | $0.00000 | $0.00006 |
| Sonnet 5 | $0.00000 | $0.00003 |
| Haiku 4.5 | $0.00000 | $0.00001 |
Grade A, and why
ad-creative 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 yesterday.
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 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.

ad-creative is a skill published in the GitHub repository alirezarezvani/claude-skills (25,247 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 13 tokens. 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 2026-08-30.

handoff
Create a structured session handoff when context is running low or work is pausing. Deep context mining, self-validation, multi-file splitting. Captures everything the next session needs.
handoffplan
Run /handoff to capture session data, then write a phased implementation plan that references it. Creates beads for tracking.
troubleshooting
Use when LibreChat has errors, containers won't start, API calls fail, file uploads break, models return errors, or something isn't working as expected. Also use for checking service health, reading logs, and diagnosing performance issues.
rag
Use when setting up LibreChat RAG (Retrieval-Augmented Generation), configuring embeddings providers, setting up file search in agents, configuring PGVector/PostgreSQL for vector storage, or troubleshooting document indexing and retrieval. Also use when users ask about 'chat with documents' or 'file search' features.
mcp
Use when configuring MCP (Model Context Protocol) servers in LibreChat, connecting external tools via MCP, setting up mcpServers in librechat.yaml, or debugging MCP tool connections. Also use when asked about extending LibreChat agents with external capabilities through MCP.
config
Use when configuring LibreChat, editing librechat.yaml, adding endpoints, setting up model providers, configuring modelSpecs, or adjusting interface settings. Also use when asked about LibreChat configuration options, YAML structure, or endpoint setup.
