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 5.1 | $0.00048 | $0.00418 |
| Opus 5 | $0.00024 | $0.00209 |
| Sonnet 5 | $0.00010 | $0.00084 |
| Haiku 4.5 | $0.00005 | $0.00042 |
Grade A, and why
tcx-order-cancel 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.
What it actually says
Cancel Submitted Order
Cancel exactly one submitted broker order through the native TradingCodex
execution gate. This skill carries no tool authority. The UserPromptSubmit
hook validates the complete prompt and calls the service-owned cancellation
boundary before any model or subagent can act.
Invocation
Enter one of these forms as the only meaningful action in the complete user prompt:
$tcx-order-cancel --ticket-id <ticket-id> --broker-order-id <broker-order-id> --approval-receipt-id <approval-receipt-id>
$tcx-order-cancel --ticket-id <ticket-id> --broker-order-id <broker-order-id> --approval-receipt-id <approval-receipt-id> --live-confirmation <token>
Replace every placeholder with the canonical identifier or confirmation token.
The skill token may instead be a Markdown link only when its label and target
match this workspace's projected tcx-order-cancel/SKILL.md. Leading blank
lines, ASCII letter case in the skill name, normalized line endings, and
line-wrapped arguments are harmless. Use literal
--name value pairs. Do not add prose, comments, another skill, quotes,
escaped values, aliases, or --name=value syntax.
Hard Stops
- Invoke this action only from a root native Codex user turn.
- Do not invoke it from Plan mode or a subagent.
- Do not use it to discard a local draft; draft discard remains a separate portfolio-manager action.
- Do not retry a
needs_reviewor uncertain result. Inspect canonical order status first. - Keep the existing approval, policy, broker-order identity, live-confirmation, idempotency, audit, and reconciliation gates intact.
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.
