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 | $0.00000 | $0.00222 |
| Opus 5 | $0.00000 | $0.00111 |
| Sonnet 5 | $0.00000 | $0.00044 |
| Haiku 4.5 | $0.00000 | $0.00022 |
Grade A, and why
sign-permit 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 6d 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
Sign Permit
Sign an EIP-2612 permit through the Agentic Vault MCP server.
When to use
Use this skill when the user wants to sign a gasless token approval (EIP-2612 permit).
Instructions
-
Use the
sign_permitMCP tool with the following parameters:chainId: The target chain IDtoken: The ERC-20 token contract addressspender: The approved spender addressvalue: The approval amount in token units (string)deadline: Unix timestamp for permit expirydomain: The EIP-712 domain objecttypes: The EIP-712 types definitionmessage: The EIP-712 message object
-
The tool enforces policy constraints before signing.
-
Never import or access signing keys directly. Always use the MCP tool.
Example
Use the sign_permit tool to approve 1000 USDC for spender 0x... on chain 1
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.

sign-permit is a skill published in the GitHub repository agenticvault/agentic-vault (4 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 222 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 2026-08-31.
