Use when auditing custom x/ modules, reviewing IBC integrations, or assessing pre-launch chain security. Updated for SDK v0.53.x.\"\n---\n\n# Cosmos Vulnerability Scanner\n\n## Purpose\n\nScan Cosmos SDK modules and CosmWasm contracts for vulnerabilities that cause chain halts, consensus failures, or fund loss. Spawns parallel scanning agents — each specializing in a vulnerability category — that return findings to the main skill, which then writes them as individual markdown files to an output directory.\n\n**Output directory**: defaults to `.bughunt_cosmos/`. If the user specifies a different directory in their prompt, use that instead.\n\n## When to Use\n\n- Auditing Cosmos SDK modules (custom `x/` modules)\n- Reviewing CosmWasm smart contracts\n- Pre-launch security assessment of Cosmos chains\n- Investigating chain halt incidents\n\n## When NOT to Use\n\n- Pure Solidity/EVM audits without Cosmos SDK — use Solidity-specific tools\n- CometBFT consensus engine internals — this covers SDK modules, not the consensus layer itself\n- General Go code review with no blockchain context\n- Cosmos SDK application logic that is not consensus-critical (e.g., CLI commands, REST endpoints)\n- CosmWasm contract-only audits on chains without custom SDK modules — use the CosmWasm checklist items alone\n\n## Essential Principles\n\n1. **Consensus path is king** — A bug only matters for chain halt/fund loss if it's on the consensus-critical execution path (BeginBlock, EndBlock, FinalizeBlock, msg_server handlers, AnteHandler). Always verify a finding is reachable from consensus before reporting it.\n2. **State divergence = chain halt** — Any non-determinism that causes validators to compute different state roots will halt the chain. This is the highest-severity class because it affects all validators simultaneously.\n3. **Check the version** — Cosmos SDK has breaking changes across major versions (v0.47 removed GetSigners, v0.50 added ABCI 2.0, v0.53 deprecated ValidateBasic). Always check `go.mod` versions before applying patterns.\n4. **False positives waste audit time** — A map iteration in a CLI command is not a consensus bug. A panic in a query handler does not halt the chain. Verify the execution context before flagging.\n5. **Cross-module interactions are where bugs hide** — The most severe findings (IBC reentrancy, EVM/Cosmos state desync, authz escalation) involve interactions between modules, not bugs within a single module.\n\n## Scanning Workflow\n\n### Phase 1: Discovery (synchronous)\n\n**Entry**: Target codebase path provided by user. Codebase contains Go source (e.g., `x/` modules, `go.mod`) or Rust contracts with `cosmwasm_std`.\n\nRun a **synchronous subagent** (Agent tool) with the full contents of [DISCOVERY.md](resources/DISCOVERY.md) as its prompt. The agent must:\n\n1. Follow the Discovery workflow to explore the target codebase\n2. Return the full CLAUDE.md content (the technical inventory and threat model) in its response\n3. Return a structured summary with exactly these fields:\n\n```\nPLATFORM: pure-cosmos | evm | wasm        (pick one; if multiple, comma-separated)\nIBC_ENABLED: true | false\nSDK_VERSION: <version from go.mod>\nIBC_GO_VERSION: <version from go.mod, or \"n/a\">\nCUSTOM_MODULES: <comma-separated list of x/* modules>\n```\n\nAfter the subagent returns, **you** (the main skill) Write the CLAUDE.md to the target repo root. Save its path and the discovery values — these feed into Phase 2.\n\n**Exit**: CLAUDE.md written by main skill. PLATFORM, IBC_ENABLED, SDK_VERSION, IBC_GO_VERSION, and CUSTOM_MODULES captured.\n\n### Phase 2: Parallel Vulnerability Scan\n\nSpawn scanning agents **in a single message** for maximum parallelism. Use the Agent Prompt Template below, filling in the reference file for each agent. Subagents only need read access (Grep, Glob, Read) — they return findings in their response and the main skill writes the files.\n\n**Always spawn these 3 agents:**\n\n| Agent Name | Reference File | Scope |\n|------------|---------------|-------|\n| `core-scanner` | `VULNERABILITY_PATTERNS.md` | §1-9: non-determinism, ABCI, signers, validation, handlers, ante security |\n| `state-scanner` | `STATE_VULNERABILITY_PATTERNS.md` | §11-23: bookkeeping, bank, pagination, events, tx replay, governance, arithmetic, encoding, deprecated modules |\n| `advanced-scanner` | `ADVANCED_VULNERABILITY_PATTERNS.md` | §24-27: storage keys, consensus validation, circuit breaker, crypto |\n\n**Spawn conditionally (in the same parallel message):**\n\n| Agent Name | Condition | Reference File |\n|------------|-----------|---------------|\n| `evm-scanner` | PLATFORM includes `evm` | `EVM_VULNERABILITY_PATTERNS.md` |\n| `ibc-scanner` | IBC_ENABLED is `true` | `IBC_VULNERABILITY_PATTERNS.md` |\n| `cosmwasm-scanner` | PLATFORM includes `wasm` | `COSMWASM_VULNERABILITY_PATTERNS.md` |\n\n#### Agent Prompt Template\n\nConstruct each agent's prompt by replacing `{REFERENCE_FILE_PATH}` with the full path to the reference file (under `{baseDir}/resources/`) and `{CLAUDE_MD_PATH}` with the path to the CLAUDE.md written in Phase 1:\n\n~~~\nPerform a very thorough security scan of a Cosmos SDK codebase for specific vulnerability patterns.\n\nCONTEXT:\nRead {CLAUDE_MD_PATH} for codebase context (SDK version, modules, threat model, key files).\n\nPATTERNS:\nRead {REFERENCE_FILE_PATH} — it contains numbered vulnerability patterns. For EACH pattern:\n1. Read the detection patterns and \"What to Check\" items\n2. Use Grep and Glob to search the target codebase for each pattern\n3. When a match is found, Read surrounding code to verify it's on a consensus-critical path (BeginBlock, EndBlock, FinalizeBlock, msg_server handlers, AnteHandler)\n4. Classify severity per the guidelines below\n\nRULES:\n- Consensus path only: Only flag code reachable from consensus-critical execution. CLI/query/test code is NOT a finding.\n- Check SDK version in go.mod before applying patterns (v0.47 removed GetSigners, v0.50 added ABCI 2.0, v0.53 deprecated ValidateBasic).\n- Always use the Grep tool for searches, not bash grep. The reference file contains search patterns — use them directly with the Grep tool.\n- Ignore cross-references to other resource files (e.g., links to IBC or COSMWASM patterns). Those patterns are covered by other scanning agents.\n- Reject these rationalizations:\n  - \"ValidateBasic catches this\" — deprecated and facultative since SDK v0.53\n  - \"Behind governance, so safe\" — governance proposals can be malicious\n  - \"IBC counterparty is trusted\" — any chain can open a channel\n  - \"Panic can't happen, input is validated\" — trace the full call chain\n  - \"Rounding error is only a few tokens\" — compounds over time, can be looped\n  - \"EVM precompile handles rollback\" — many have incomplete rollback\n\nSEVERITY:\n- Critical (fund loss): signer mismatch, broken bookkeeping, AnteHandler bypass, bank keeper misuse, IBC token inflation, EVM/Cosmos desync, Merkle proof forgery, arithmetic overflow\n- High (chain halt): non-determinism, ABCI panics, slow ABCI, non-deterministic IBC acks, consensus gaps, CacheContext event leak\n- Medium (DoS): unbounded pagination, tx replay, missing validation, governance spam, rate limiting, circuit breaker bypass, storage key collisions\n- Low (logic): rounding errors, stub handlers, event override, module ordering\n\nOUTPUT — RETURN FORMAT:\nDo NOT write any files. Return ALL findings and the summary in your response.\n\nFor each pattern, return one of:\n  §NUM PATTERN_NAME: Not applicable — [one-line reason]\n  §NUM PATTERN_NAME: FINDING (followed by the finding block below)\n\nFor each finding, include the full content using this template:\n\nFINDING_FILE: {SEVERITY}-s{SECTION_NUM}-{kebab-description}.md\n## [SEVERITY] Title\n**Location**: `file:line`\n**Description**: What the bug is and why it matters\n**Vulnerable Code**: [snippet]\n**Attack Scenario**: [numbered steps]\n**Recommendation**: How to fix\n**References**: [links to relevant advisories or building-secure-contracts]\n\nYou MUST report on ALL patterns in the reference file — do not skip any.\n~~~\n\n**Exit**: All scanning agents returned. Each reported on every pattern in their reference file.\n\n### Phase 3: Write Findings\n\nAfter all scanning agents return, write finding files to the output directory (default `.bughunt_cosmos/`):\n\n1. Parse each agent's response for `FINDING_FILE:` blocks\n2. For each finding, Write the content to `{OUTPUT_DIR}/{filename}` using the filename from `FINDING_FILE:`\n3. Create the output directory first if it doesn't exist\n\n### Phase 4: Verify Completeness\n\nAfter writing all findings, verify every pattern was assessed:\n\n1. Collect the summary lines (§NUM entries) returned by each agent\n2. Check pattern counts against expected totals:\n   - `core-scanner`: 8 patterns (§1-9, excluding §8 legacy-only)\n   - `state-scanner`: 13 patterns (§11-23)\n   - `advanced-scanner`: 4 patterns (§24-27)\n   - `evm-scanner` (if spawned): 10 patterns (§1-10)\n   - `ibc-scanner` (if spawned): 16 patterns (§1-16)\n   - `cosmwasm-scanner` (if spawned): 3 patterns (§1-3)\n3. If any pattern is missing from a summary, flag it and re-prompt that agent\n4. List all finding files written to the output directory with a `Glob` for `*.md`\n\n**Exit**: All patterns accounted for. Finding files listed for the user.\n\n---\n\n## Success Criteria\n\n- [ ] Discovery CLAUDE.md written with complete technical inventory and threat model\n- [ ] All scanning agents completed and reported on every pattern in their reference file\n- [ ] Pattern counts verified against expected totals (no patterns skipped)\n- [ ] All findings written to output directory as individual markdown files\n- [ ] Each finding file includes: severity, location, vulnerable code, attack scenario, recommendation\n\n---\n\n## Resources\n\n- **Discovery & CLAUDE.md**: [DISCOVERY.md](resources/DISCOVERY.md)\n- **Core patterns (§1-9)**: [VULNERABILITY_PATTERNS.md](resources/VULNERABILITY_PATTERNS.md)\n- **State & module patterns (§11-23)**: [STATE_VULNERABILITY_PATTERNS.md](resources/STATE_VULNERABILITY_PATTERNS.md)\n- **Advanced patterns (§24-27)**: [ADVANCED_VULNERABILITY_PATTERNS.md](resources/ADVANCED_VULNERABILITY_PATTERNS.md)\n- **IBC vulnerabilities**: [IBC_VULNERABILITY_PATTERNS.md](resources/IBC_VULNERABILITY_PATTERNS.md)\n- **CosmWasm vulnerabilities**: [COSMWASM_VULNERABILITY_PATTERNS.md](resources/COSMWASM_VULNERABILITY_PATTERNS.md)\n- **EVM vulnerabilities**: [EVM_VULNERABILITY_PATTERNS.md](resources/EVM_VULNERABILITY_PATTERNS.md)\n- **Building Secure Contracts**: `building-secure-contracts/not-so-smart-contracts/cosmos/`\n- **Cosmos SDK Docs**: https://docs.cosmos.network/\n- **CodeQL for Cosmos SDK**: https://github.com/crypto-com/cosmos-sdk-codeql\n","tagline":"Scans Cosmos SDK blockchain modules and CosmWasm contracts for consensus-critical vulnerabilities — chain halts, fund loss, state divergence. 25 core + 16 IBC + 10 EVM + 3 CosmWasm patterns.
