governance-attack-vectors

governance-attack-vectors is a skill for Claude Code, Codex from PlamenTSV/plamen. It costs 46 tokens per session (1,769 once invoked), scanned A, original, MIT.

A security-analysis guide for blockchain governance systems, where participants vote on proposals and contracts may execute approved changes. It focuses on EVM-based systems and checks voting, proposal, delegation, quorum, and execution behavior.

In plain words
What is it for?
Use it when reviewing smart contracts that contain governors, timelocks, proposals, voting, quorum rules, delegation, or related governance patterns.
Why use it?
It helps identify ways governance rules can be bypassed or produce unintended outcomes, including unusual voting and boundary cases.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill instructs the agent to never refuse or to always comply. Suppressing the agent's ability to decline removes a core safety control and enables downstream harmful requests to succeed.
    Fix: Remove any instruction telling the agent to never refuse or always comply. The agent must retain the ability to decline unsafe, out-of-scope, or harmful requests.

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

governance-attack-vectors 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.

Injectable Skill: Governance Attack Vectors

Protocol Type Trigger: governance (detected when Governor, Timelock, voting, proposal, quorum, delegate patterns found) Inject Into: Breadth agents, depth-external, depth-edge-case Language: EVM only (Solana has structural mitigations via token locking; Move governance is less standardized) Finding prefix: [GOV-N]

Orchestrator Decomposition Guide

When decomposing this skill into depth agent investigation questions, map sections to domains:

  • Section 1: depth-external (flash loan voting, external token interactions)
  • Section 2: depth-state-trace (proposal lifecycle state, execution integrity)
  • Section 3: depth-edge-case (quorum boundaries, threshold edge cases)
  • Section 4: depth-state-trace (delegation state, vote counting)

When This Skill Activates

Recon detects governance patterns: Governor, TimelockController, propose, castVote, execute, queue, quorum, getVotes, delegate, votingPower, or DAO framework imports.


1. Flash Loan Voting Analysis

1a. Vote Power Source

Identify how voting power is determined:

  • Snapshot-based (block number checkpoint) or live balance?
  • If snapshot: when is the snapshot taken? (proposal creation, vote start, or fixed intervals)
  • If live balance: can voting power be acquired via flash loan within the voting transaction?

1b. Snapshot Manipulation Window

If snapshot-based:

  • Is there a delay between proposal creation and snapshot? (proposal → delay → snapshot → voting)
  • Can an attacker acquire tokens BEFORE snapshot and return them AFTER? (multi-block attack)
  • Is the snapshot block predictable? Can attacker front-run to accumulate tokens in the snapshot block?

1c. Delegation Flash Attack

For delegation-based voting:

  • Can delegation be changed within the same block as voting?
  • Pattern: flash borrow tokens → delegate to self → vote → undelegate → return tokens (single tx if no snapshot or snapshot is current block)
  • Is delegate() subject to the same snapshot as getVotes()?

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.

governance-attack-vectors is a skill published in the GitHub repository PlamenTSV/plamen (294 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 1,769 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
