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-review 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 8d 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.

What it actually says

You are the great_cto /tax-review command. Run the tax-reviewer on the current project and report findings.

Step 1 — Locate ARCH doc

ARGS="${ARGUMENTS:-}"
SLUG="$ARGS"
if [ -z "$SLUG" ]; then
  ARCH=$(ls docs/architecture/ARCH-*.md 2>/dev/null | sort -V | tail -1)
  [ -z "$ARCH" ] && echo "BLOCKED: no ARCH doc; run /architect first" && exit 1
  SLUG=$(basename "$ARCH" .md | sed 's/^ARCH-//')
else
  ARCH="docs/architecture/ARCH-${SLUG}.md"
  [ ! -f "$ARCH" ] && echo "BLOCKED: $ARCH not found" && exit 1
fi
echo "Reviewing: $ARCH"

Step 2 — Detect tax-prep signals (skip if none)

TAX_HITS=$(grep -ciE "\bptin\b|circular 230|form 8879|\bmef\b|pub(lication)? 4557|section 7216|tax prep|e-file|irs|1040|efin" "$ARCH" .great_cto/PROJECT.md 2>/dev/null || echo 0)
if [ "$TAX_HITS" -eq 0 ]; then
  echo "No tax-prep/e-file signals in ARCH or PROJECT.md — skipping tax review."
  exit 0
fi

Step 3 — Invoke tax-reviewer

Use the Agent tool with subagent_type: tax-reviewer and prompt:

Review docs/architecture/ARCH-${SLUG}.md and .great_cto/PROJECT.md. Produce docs/sec-threats/TM-tax-${SLUG}.md using the template at skills/great_cto/templates/TM-tax.md. Report critical/high findings and append the HANDOFF block. Verdict: signed-off or blocked.

Step 4 — Surface verdict

After agent completes, print:

  • TM file path
  • Critical / High counts
  • Verdict (signed-off | blocked)
  • List of gates raised (gate:tax-filing-signoff, …)
  • Next action: if blocked → fix critical items, re-run; if signed-off → notify EA/CPA compliance lead to approve gate:tax-filing-signoff.

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.
