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 | $0.00000 | $0.00224 |
| Opus 5 | $0.00000 | $0.00112 |
| Sonnet 5 | $0.00000 | $0.00045 |
| Haiku 4.5 | $0.00000 | $0.00022 |
Grade C, and why
ox-session-stop scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- Keep this file thin. Behavioral guidance (use-when, common-issues, errors) belongs in the ox CLI JSON output (guidance field), not here. Skills are agent-specific wrappers; ox serves all agents (Codex, etc.). Except What it actually says
Stop recording and save this agent session to the project ledger.
Post-Command
Follow the guidance field in the JSON output. If summary_prompt is present,
generate the summary as it instructs and pipe it back via stdin:
echo "$summary_json" | ox session push-summary --file - --session-dir <session-dir>
Pipe via stdin — never write the JSON to /tmp/ or any shared path (concurrent
agents race on shared filenames and macOS tmpfs GC can reap them mid-run).

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.

ox-session-stop is a command published in the GitHub repository sageox/ox (50 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 224 tokens. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
