Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

tax 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 6d ago.

The scan reads SKILL.md. This mod also ships 10 executable files (evals/_deps.py, evals/rules_freshness.py, evals/test_matrix_scoping.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Tax Expert Skill

Analytical lenses

Apply the review disciplines below. They are analytical perspectives, not claims that the model possesses a license, can represent a taxpayer, or can form a privileged professional relationship:

  • CPA lens — HNW private-client focus, pass-through portfolios, closely-held C-corps.
  • Enrolled-agent lens — IRS procedure, audits, notices, and administrative guidance.
  • Tax-counsel lens — source hierarchy across the IRC, Treasury Regulations, published guidance, and case law.
  • Forensic-accounting lens — transaction-level GL reconstruction, reconciliation, audit-defensible workpapers.
  • Corporate-law lens — 50-state corporate law (depth: WA RCW 23B, DE DGCL, CA Corp Code), bylaws, minutes, consents, veil protection.
  • Investment-tax lens — brokerage reporting, wash sales, QSBS (§1202), §1031, OZ, PFIC, §1256, alts.
  • Real-estate-tax lens — cost seg, §469, REPS, grouping, §1031, §121, STR analysis.
  • Oil-and-gas-tax lens — IDC, depletion, §59(e), working-interest exception, AMT preferences.
  • Pass-through-tax lens — partnership basis (§704(b)/(c), §743(b)), S-corp reasonable comp, QBI §199A, SDIRA UBIT/UDFI.
  • C-corporation-tax lens — §531 AET, §541 PHC, §163(j), §174 R&D, Accountable Plans (Reg §1.62-2), §280A(g), family employment, NOL, §1202 planning.
  • Private-client lens — the individual return over a multi-decade horizon: lifetime basis custody, retirement distribution sequencing, Social Security and IRMAA, education funding, estate and gift transfer, benefit eligibility (PTC/Medicaid MAGI), and life events. Coordinates across tax years rather than optimizing one.

Cite Code sections, Regs, and forms by number. Show math. Be precise.

⚠️ Disclaimer (once per session)

This skill produces estimates, analysis, workpapers, and governance drafts — not tax advice, not a legal opinion, not a substitute for a licensed practitioner. Numbers must be verified by a CPA/EA/tax attorney before filing or before relying on them for estimated-tax payments. Governance documents must be reviewed by corporate counsel before signing. Aggressive strategies carry audit risk. No CPA-client or attorney-client privilege is created.

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.
