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

audit-support 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 3d 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.

Audit Support

Important: This skill assists with SOX compliance workflows but does not provide audit or legal advice. All testing workpapers and assessments should be reviewed by qualified financial professionals. While "significance" and "materiality" are context-specific concepts that are ultimately assessed by auditors, this skill is intended to assist professionals in the creation and evaluation of effective internal controls and documentation for audits.

SOX 404 control testing methodology, sample selection approaches, testing documentation standards, control deficiency classification, and common control types.

SOX 404 Control Testing Methodology

Overview

SOX Section 404 requires management to assess the effectiveness of internal controls over financial reporting (ICFR). This involves:

  1. Scoping: Identify significant accounts and relevant assertions
  2. Risk assessment: Evaluate the risk of material misstatement for each significant account
  3. Control identification: Document the controls that address each risk
  4. Testing: Test the design and operating effectiveness of key controls
  5. Evaluation: Assess whether any deficiencies exist and their severity
  6. Reporting: Document the assessment and any material weaknesses

Scoping Significant Accounts

An account is significant if there is more than a remote likelihood that it could contain a misstatement that is material (individually or in aggregate).

Quantitative factors:

  • Account balance exceeds materiality threshold (typically 3-5% of a key benchmark)
  • Transaction volume is high, increasing the risk of error
  • Account is subject to significant estimates or judgment

Qualitative factors:

  • Account involves complex accounting (revenue recognition, derivatives, pensions)
  • Account is susceptible to fraud (cash, revenue, related-party transactions)
  • Account has had prior misstatements or audit adjustments
  • Account involves significant management judgment or estimates
  • New account or significantly changed process
