audit-algorand

audit-algorand is a skill for Claude Code, Codex from initlabsai/vibekit. It costs 97 tokens per session (1,264 once invoked), scanned A, original, MIT.

A security review guide for TypeScript applications on Algorand, a blockchain platform, including smart contracts and LogicSigs compiled with PuyaTs.

In plain words
What is it for?
Use it for vulnerability assessments, threat modeling, exploit analysis, mainnet-readiness reviews, security findings, and advice on fixing issues in Algorand contracts and clients.
Why use it?
It helps find weaknesses by checking what an attacker could actually do and explaining which safety rule is broken. It also defines what code, generated files, tests, and network settings were reviewed.

Token cost

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.

Security

Grade A, and why

audit-algorand 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.

Audit Algorand contracts

Audit the behavior an attacker can reach, then explain each issue through a violated invariant and a reproducible path. A checklist is coverage support; it is not evidence that a vulnerability exists.

This skill covers Algorand TypeScript and PuyaTs. Do not introduce Python, PyTEAL, Beaker, or raw-TEAL implementation guidance. Load build-on-algorand when the user also asks to implement fixes or needs broader PuyaTs application guidance. Load use-vibekit before any deployment, signing, network, account, LocalNet, or on-chain action.

Establish scope before judging safety

Read the repository instructions, package manifests, lockfile, compiler configuration, contract source, generated ARC-56 and TEAL artifacts, clients, and tests that are in scope. Use the project's pinned commands and dependencies. Do not add a dependency or change production code during an audit unless the user explicitly asks for remediation.

Record:

  • the reviewed commit or working-tree state;
  • included contracts, LogicSigs, clients, artifacts, and tests;
  • target network and active or assumed consensus protocol;
  • compiler and optimization settings;
  • excluded components and assumptions;
  • whether generated artifacts match the reviewed source;
  • commands that ran, failed, or could not run.

Treat missing source, stale artifacts, failing tests, and unverified deployment bytecode as limitations. Do not silently fill those gaps with assumptions.

Load the audit guides

Read Methodology and reporting for every audit. Then load every guide whose feature appears in the system:

Surface Guide
ABI methods, privileges, lifecycle handlers, upgrades, deletion, pausing Applications and authorization
Payments, asset transfers, inner transactions, fees, atomic groups, ASA control Transactions and assets
Local/global/box state, clear state, MBR, state machines, accounting, numeric formulas State and arithmetic
Contract-account or delegated smart signatures Logic Signatures
Randomness, oracles, compiler and artifact verification, clients, keys, monitoring External systems and release

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.
