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 | $0.02840 | $0.02840 |
| Opus 5 | $0.01420 | $0.01420 |
| Sonnet 5 | $0.00568 | $0.00568 |
| Haiku 4.5 | $0.00284 | $0.00284 |
Grade C, and why
aptos-agent-skills CLAUDE.md scanned grade C with 1 finding 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.
Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

Aptos Agent Skills
Specialized skills for AI assistants to build secure, modern Aptos dApps.
Project Scaffolding
Use npx create-aptos-dapp to start new projects. Ask the user which network (devnet, testnet, mainnet) before
scaffolding, then use the same <network> value for both create-aptos-dapp and aptos init:
# Fullstack dApp with Vite (frontend + contracts)
npx create-aptos-dapp my-dapp \
--project-type fullstack \
--template boilerplate-template \
--framework vite \
--network <network>
# Fullstack dApp with Next.js
npx create-aptos-dapp my-dapp \
--project-type fullstack \
--template boilerplate-template \
--framework nextjs \
--network <network>
# Contract-only (Move project)
npx create-aptos-dapp my-contract \
--project-type move \
--network <network>
API Key: If the user has a Geomi API key, pass
--api-key <key>during scaffolding. It's optional for devnet but recommended for testnet/mainnet to avoid rate limits. Get one at https://geomi.dev (create project → API Resource → copy key).
Post-scaffold checklist:
cd <project-name>- Verify
.envis in.gitignorebefore any git operations - Run
aptos init --network <network> --assume-yes(use the same network as thecreate-aptos-dappcommand above) - Verify:
npm run move:compile && npm run move:test git init && git add . && git commit -m "Initial commit"

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.

aptos-agent-skills CLAUDE.md is an instructions file published in the GitHub repository aptos-labs/aptos-agent-skills (19 stars, last pushed 2mo ago), licensed MIT. It adds 2,840 tokens to every session, about $0.0142 per session on Opus 5. A static security scan graded it C with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
