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 | $0.00039 | $0.03902 |
| Opus 5 | $0.00019 | $0.01951 |
| Sonnet 5 | $0.00008 | $0.00780 |
| Haiku 4.5 | $0.00004 | $0.00390 |
Grade A, and why
starknet-wallet 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 12d 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.

Starknet Wallet Skill
Manage Starknet wallets for AI agents with native Account Abstraction support.
When to Use
- Creating, funding, and operating Starknet accounts for agent workflows.
- Checking balances, sending transfers, managing session keys, or invoking contracts from an agent wallet.
When NOT to Use
- DeFi-specific routing, staking, or lending flows better covered by
starknet-defi. - Cairo contract authoring, deployment-only operations, or security auditing.
Quick Start
- Install the SDK dependencies and set Starknet RPC/account environment variables.
- Use skills catalog to pivot to adjacent modules like DeFi, deployment, or auditing.

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

starknet-wallet is a skill published in the GitHub repository keep-starknet-strange/starknet-agentic (80 stars, last pushed today), licensed MIT. It adds 39 tokens to every session and 3,902 once invoked, about $0.0002 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 2026-08-30.
