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 | $0.00031 | $0.01109 |
| Opus 5 | $0.00015 | $0.00554 |
| Sonnet 5 | $0.00006 | $0.00222 |
| Haiku 4.5 | $0.00003 | $0.00111 |
Grade A, and why
tcx-server 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.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TCX Server
Use this skill for TradingCodex status checks, service recovery, viewer URL guidance, MCP setup, update status, and safe broker connector inspection.
Runtime Sources
- Treat the TradingCodex session-start context injected by the hook as the initial service and update snapshot. Do not reread its backing files through a shell command.
- Refresh product status with the read-only
get_tradingcodex_statusMCP tool. - Refresh package and workspace update readiness with the read-only
get_update_statusMCP tool. - Inspect connectors only through read-only MCP tools such as
list_broker_connections,get_broker_connection_status,list_broker_adapter_providers,get_broker_capability_profile,get_broker_instrument_constraints,get_connector_build_status, andget_order_status, when the current role permits them.
Procedure
- Start with the injected session context, then call only the smallest read-only MCP tool needed to refresh stale or missing information.
- Report service reachability, compatibility, readiness, package/workspace versions, DB mismatch, port conflict, update availability, and the viewer URL only when those fields are present in trusted status output.
- If startup context reports
version_mismatch,db_mismatch, orport_occupied, explain the recorded issue and next action before recommending the viewer. - If recovery, doctor, service lifecycle, or package update requires the launcher, stop and give an explicit interactive user-terminal handoff. Do not invoke the launcher from this skill.
- If managed Build work is requested, give a new root-turn prompt whose exact
first meaningful invocation is the canonical plain
$tcx-buildtoken and whose following line states the requested change. Explain that an equivalent matching workspace skill link is accepted interactively, but the plain token is the path-independent handoff. The marker grants no authority beyond the current Codex sandbox and TradingCodex policy. - For OpenBB, give the requested user-terminal command only. TradingCodex stores environment-variable names, never values; run an update and restart Codex after a change.
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-server is a skill published in the GitHub repository monarchjuno/tradingcodex (364 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 31 tokens to every session and 1,109 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.
