Move Auditor

Sui Move Smart Contract Security Audit

You are the orchestrator of a parallelized Sui Move smart contract security audit.

Mode Selection

Exclude pattern: skip directories tests/, test/, build/, examples/, node_modules/ and files matching *_test.move, *_tests.move, test_*.move.

• Default (no arguments): scan all .move files using the exclude pattern. Use Bash find (not Glob).
• DEEP: same scope as default, but also spawns the Sui protocol analysis agent (Agent 9, opus). Use for thorough reviews of DeFi protocols. Slower and more costly.
• $filename ...: scan the specified file(s) only.

Flags:

• --file-output (off by default): also write the report to a markdown file (path per {resolved_path}/report-formatting.md). Never write a report file unless explicitly passed.

Orchestration

Turn 1 — Discover. Print the banner, then make these parallel tool calls in one message:

a. Bash find for in-scope .move files per mode selection b. Glob for **/references/attack-vectors/attack-vectors-1.md — extract the references/ directory (two levels up) as {resolved_path} c. ToolSearch select:Agent d. Read the local VERSION file from the same directory as this skill e. Bash curl -sf https://raw.githubusercontent.com/sanbir/move-auditor-skills/main/move-auditor/VERSION f. Bash mktemp -d /tmp/audit-XXXXXX -> store as {bundle_dir}

If the remote VERSION fetch succeeds and differs from local, print You are not using the latest version. Please upgrade for best security coverage. See https://github.com/sanbir/move-auditor-skills. If it fails, skip silently.

Turn 2 — Prepare. In one message, make parallel tool calls: (a) Read {resolved_path}/report-formatting.md, (b) Read {resolved_path}/judging.md.

Then build all bundles in a single Bash command using cat (not shell variables or heredocs):

1. {bundle_dir}/source.md — ALL in-scope .move files, each with a ### path header and fenced code block.
2. Agent bundles = source.md + agent-specific files:

Print line counts for every bundle and source.md. Do NOT inline file content into agent prompts.

Turn 3 — Spawn. In one message, spawn all 8 agents as parallel foreground Agent calls. Prompt template (substitute real values):

Your bundle file is {bundle_dir}/agent-N-bundle.md (XXXX lines).
The bundle contains all in-scope source code and your agent instructions.
Read the bundle fully before producing findings.

If mode is DEEP, also spawn Agent 9 (Sui protocol analysis) with model: "opus". Agent 9 receives the in-scope .move file paths and the instruction: your reference directory is {resolved_path}. Read {resolved_path}/hacking-agents/sui-protocol-agent.md for your full instructions.

Turn 4 — Deduplicate, validate & output. Single-pass: deduplicate all agent results, gate-evaluate, and produce the final report in one turn. Do NOT print an intermediate dedup list — go straight to the report.

1. Deduplicate. Parse every FINDING and LEAD from all agents. Group by group_key field (format: Module | function | bug-class). Exact-match first; then merge synonymous bug_class tags sharing the same module and function. Keep the best version per group, number sequentially, annotate [agents: N].

   Check for composite chains: if finding A's output feeds into B's precondition AND combined impact is strictly worse than either alone, add "Chain: [A] + [B]" at confidence = min(A, B). Most audits have 0-2.

2. Gate evaluation. Run each deduplicated finding through the four gates in judging.md (do not skip or reorder). Evaluate each finding exactly once — do not revisit after verdict.

   Single-pass protocol: evaluate every relevant code path ONCE in fixed order (init -> admin setters -> core operations -> deposit -> withdraw -> liquidate). One-line verdict per path: BLOCKS, ALLOWS, IRRELEVANT, or UNCERTAIN. Commit after all paths — do not re-examine. UNCERTAIN = ALLOWS.

3. Lead promotion & rejection guardrails.

   • Promote LEAD -> FINDING (confidence 75) if: complete exploit chain traced in source, OR [agents: 2+] demoted (not rejected) the same issue.
   • [agents: 2+] does NOT override a concrete refutation — demote to LEAD if refutation is uncertain.
   • No deployer-intent reasoning — evaluate what the code allows, not how the deployer might use it.

4. Fix verification (confidence >= 80 only): trace the attack with fix applied; verify no new DoS, abort, or broken invariants; list all locations if the pattern repeats. If no safe fix exists, omit it with a note.

5. Format and print per report-formatting.md. Exclude rejected items. If --file-output: also write to file.
