staking-receipt-tokens

staking-receipt-tokens is a skill for Claude Code, Codex from PlamenTSV/plamen. It costs 24 tokens per session (2,416 once invoked), scanned A, original, MIT.

A security review guide for staking receipt tokens, which represent a user’s deposited stake or claim on staking rewards.

In plain words
What is it for?
Use it to trace staking, delegation, deposit, withdrawal, and reward flows and check whether receipt or external staking tokens can be transferred unexpectedly.
Why use it?
It helps identify donation attacks and accounting errors caused by tokens being transferable or sent to a protocol without its approval.

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

staking-receipt-tokens 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 11d 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.

Skill: Staking Receipt Token Analysis

Type: Thought-template (instantiate before use) Research basis: Donation attacks via unsolicited token transfers

Trigger Patterns

delegation|staking.*receipt|liquid.*staking|getLiquidRewards|unbond|
stake.*share|validator|deposit.*voucher|withdraw.*voucher|claimReward

Reasoning Template

Step 1: Identify Receipt Tokens

  • In {CONTRACTS}, find all external calls that return tokens
  • For each, determine:
    • What token type is returned? (shares, vouchers, receipts, LP tokens)
    • Is the returned token ERC20-compatible?
    • Does the protocol hold these tokens?

Step 2: Check Transferability

  • For each receipt token {RECEIPT_TOKEN}:
    • Can it be acquired externally? (stake directly with {EXTERNAL_STAKING})
    • Can it be transferred via standard transfer()/transferFrom()?
    • Can anyone transfer it to {PROTOCOL_CONTRACT} unsolicited?

Step 2b: External Token Transferability

For each EXTERNAL staking/delegation token the protocol interacts with (not just the protocol's own receipt token):

  1. Is it ERC20-transferable? (check if extends IERC20/IERC20Upgradeable)
  2. Can it be transferred TO the protocol contract unsolicited (without calling deposit/stake)?
  3. If YES to both: a. Does the protocol iterate over these tokens or their sources? (gas DoS from many unsolicited transfers) b. Does getTotalStake(protocol) or equivalent change? (accounting impact on withdrawal calculations) c. Does transfer() trigger side effects? (reward auto-claim, delegation state changes) d. Does non-zero balance block any admin/privileged operations? (e.g., entity removal requires balance == 0)
External Token ERC20? Unsolicited Transfer? Iteration DoS? Balance Impact? Side Effects? Blocks Operations?
