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

account-lifecycle 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 7d 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.

ACCOUNT_LIFECYCLE Skill

Trigger Pattern: ACCOUNT_CLOSING flag detected (close/CloseAccount usage) Inject Into: Breadth agents, depth agents Finding prefix: [AL-N] Rules referenced: S4, R9

For every account close operation in the Solana program:

1. Close Operation Inventory

List all account closing operations:

# Instruction Account Closed Close Method Lamport Recipient Location
1 {ix} {account} Anchor close / manual {recipient} {file:line}

2. Close Completeness

For each close operation, verify ALL steps:

Close Op Data Zeroed? Lamports Transferred? Discriminator Set to CLOSED? Owner Transferred to System?
{op} YES/NO YES/NO YES/NO YES/NO

Anchor close: Handles all 4 steps automatically. Manual closing MUST do all 4. Missing step impact:

  • Data not zeroed → residual data readable by other programs
  • Lamports not fully transferred → rent-exempt lamports stranded (Rule 9)
  • Discriminator not set → account can be "reopened" with stale type
  • Owner not transferred → program still has authority over closed account

3. Revival Attack Analysis (S4 - CRITICAL)

For each close operation:

Close Op Same-Tx Refund Possible? Revival Guard? Attack Sequence
{op} YES/NO YES/NO {if YES: describe}

Attack (S4): Within the SAME transaction, after an account is closed (lamports drained, data zeroed):

  1. Close account (lamports go to attacker)
  2. In same tx, re-fund account with lamports (becomes rent-exempt again)
  3. Account data is all zeros but account exists again
  4. Next instruction that checks account.data_len() > 0 or assumes "closed accounts don't exist" fails

Defense: Set discriminator to a CLOSED sentinel value. Check discriminator on every access, not just data length.

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.
