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 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 2d 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.

What it actually says

Stop recording and save this agent session to the project ledger.

Post-Command

After the command completes, check the JSON output for guidance and summary_prompt fields. Follow the guidance field for next steps.

If summary_prompt is present (sync mode):

  1. Read the prompt carefully — it references the raw session file on disk
  2. Read the raw session file at the path specified in the prompt
  3. Generate the summary JSON following the Output Format in the prompt
  4. Save it to a temporary file (e.g., .ox-summary.json in the workspace root, or /tmp/ox-summary.json) — do NOT write to the session cache dir as it may be outside the workspace sandbox
  5. If the prompt includes a push-summary step, run that command with --file pointing to your temp file
  6. Verify the push succeeded by checking the JSON output for "success": true
  7. Clean up the temporary summary file

If summary_prompt is absent (async mode): No agent action required. Upload and summary generation happen automatically in the background.

If summary generation fails:

  • Run ox agent <id> doctor — it can detect and help recover missing summaries
  • The session data is safe regardless; only the rich summary is missing

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.
