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 A, and why

trace-claude-code 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 1mo 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.

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Opik Claude Code Session Tracing

This command enables/disables automatic tracing of your Claude Code sessions to Opik.

Based on the user's request: $ARGUMENTS

Scope

Tracing can be enabled at two levels:

  • Project (default): .claude/.opik-tracing-enabled in the current project directory.
  • Global (--global flag): ~/.claude/.opik-tracing-enabled, which enables tracing for every project.

The project-level file takes precedence over the global one, so a single project can override the global setting (including turning tracing off while it is enabled globally).

File Semantics

For both the project and global files:

  • File contains off or disabled → tracing disabled (used to opt a project out of a global enable)
  • File contains debug → tracing + debug logging
  • File exists with any other content (or empty) → tracing enabled
  • File doesn't exist → no opinion at this level (fall through to the next level)

Resolution order (first match wins): project off → project enabled → global enabled → disabled.

Actions

Determine the target file from the flags:

  • If --global (or --user) is present, target is ~/.claude/.opik-tracing-enabled.
  • Otherwise, target is .claude/.opik-tracing-enabled in the current directory.

If the request contains "start":

  • Create the parent .claude/ directory if needed with mkdir -p.
  • If --debug is present, write debug to the target file.
  • Otherwise, write an empty file / touch the target file (content doesn't matter).
  • Confirm scope: "Opik session tracing enabled [globally for all projects | for this project]. Takes effect immediately for new conversation turns."

If the request contains "stop":

  • If --global is present: delete ~/.claude/.opik-tracing-enabled. Confirm: "Opik session tracing disabled globally."
  • Otherwise (project stop):
    • Check whether the global file ~/.claude/.opik-tracing-enabled exists and is not itself off/disabled.
    • If global tracing is active, write off to .claude/.opik-tracing-enabled (an explicit opt-out that overrides the global enable), and confirm: "Opik session tracing disabled for this project (overriding the global setting)."
    • If global tracing is not active, delete .claude/.opik-tracing-enabled, and confirm: "Opik session tracing disabled for this project."
