Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00032 | $0.00300 |
| Opus 5 | $0.00016 | $0.00150 |
| Sonnet 5 | $0.00006 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
tcx-policy 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 5d 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
Policy Review
Use this skill to evaluate restricted list, approval readiness, policy constraints, universe/instrument support, adapter eligibility, and information barriers.
Universe and policy posture:
- Identify the asset universe, instrument, order path, broker/adapter, and whether that path is installed and enabled.
- Treat unsupported universes or instruments as
revise,deny, orblocked; do not infer permission from research-only support. - Confirm that external data tools, imported skills, or connector availability do not widen execution permissions.
- Live execution remains disabled unless a user-installed adapter and policy explicitly enable it.
Expected output:
- Policy decision: allow, revise, or deny
- Reasons
- Required approvals
- Restricted list result
- Universe/instrument support result
- Adapter eligibility result
- Barrier concerns
- Audit notes
Role-specific quality:
- Name the exact policy, restricted-list, approval, or adapter gate that matters.
- Distinguish a policy deny from an incomplete-evidence revise state.
- State safe next action, blocked actions, and whether the request is research-only, paper eligible, reviewed-provider eligible, or unsupported.
- Do not fabricate policy state, restricted-list entries, approval receipts, or adapter availability.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

tcx-policy is a skill published in the GitHub repository monarchjuno/tradingcodex (366 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 300 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
