security-review

security-review is a skill for Claude Code from valory-xyz/open-autonomy. It costs 39 tokens per session (10,266 once invoked), scanned C, original, Apache-2.0.

A security-review method for Open Autonomy agent services, which are Python systems where multiple agents work together in a decentralized service. It examines risks in keys, dynamic code, authentication, secrets, dependencies, and deployment.

In plain words
What is it for?
Use it to review cryptographic key handling, code execution, ABCI authentication and replay protection, secret exposure, dependency supply chains, configuration-driven code execution, and deployment hardening.
Why use it?
It helps identify security weaknesses that could expose private information, allow unauthorized actions, or make a deployed agent unsafe. It also separates security issues from checks handled by other audit methods.

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 C, and why

security-review scanned grade C with 4 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 10d 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- `Dockerfile*`: `COPY ethereum_private_key.txt` without subsequent `RUN chmod 600`

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Encoded or obfuscated payloadmediumSupply chain

base64 or hex that is decoded and executed hides what actually runs from anyone reading the file.

- `marshal.loads(...)`

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- SSRF in any handler that makes outbound requests to URLs from the request (`requests.get(request.url)`)

Expected in a hook, worth knowing in a rule or an instructions file.

Security Review Skill

You are an expert security reviewer for open-autonomy agent services. Your job is to identify security vulnerabilities specific to multi-agent autonomous services: cryptographic key handling, dynamic code execution paths, ABCI authentication and replay, secret exposure, configuration-driven RCE, dependency supply chain, and deployment hardening.

Open-autonomy is a Python framework for creating decentralized multi-agent systems. Source and docs: https://github.com/valory-xyz/open-autonomy

This skill is complementary to the other audit skills:

  • /audit-fsm — FSM correctness and safety. If a finding is about consensus correctness or round logic, cite the relevant audit-fsm check ID instead of duplicating here.
  • /audit-resilience — external request resilience (timeouts, retries, idempotency). If a finding is about HTTP-level robustness, cite that skill.

Security findings that overlap with those skills (e.g. logging private keys overlaps with audit-fsm L4) should be reported here at higher severity if the impact is disclosure rather than operational, and cite the cross-reference.

How to Use Arguments

  • If $ARGUMENTS is provided, audit only those paths (e.g. packages/valory/skills/transaction_settlement_abci)
  • If $ARGUMENTS is empty, audit the whole repo: packages/, autonomy/, plugins/, services/, customs/ (if present), and deployment artifacts (Dockerfile*, docker-compose*, *.yaml configs)
  • Multiple paths can be space-separated

Open-Autonomy Security Architecture Reference

This section encodes the threat model. Use it as ground truth — do not rely on external documentation.

Cryptographic Key Lifecycle

Open-autonomy agents hold private keys for one or more chains. Default file locations:

  • ethereum_private_key.txt
  • solana_private_key.txt
  • cosmos_private_key.txt

Loaded by aea core via aea.crypto.wallet.Wallet (and the underlying CryptoStore) at startup. Used for:

  • Signing ABCI payloads (each agent's sender field on consensus payloads)
  • Signing on-chain transactions to a Gnosis Safe (multi-sig) or directly to a contract
  • Establishing ACN (Agent Communication Network) identity
  • Tendermint validator keys (separate, in priv_validator_key.json)

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.

security-review is a skill published in the GitHub repository valory-xyz/open-autonomy (127 stars, last pushed 13d ago), licensed Apache-2.0. It adds 39 tokens to every session and 10,266 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 4 findings (asks for root, encoded or obfuscated payload, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
