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

used 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 9d 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.

Usage Tracker

Show which skills, hooks, rules, plugins, and MCP tools were activated in the current conversation.

Arguments

  • No arguments (default): report usage for the last user prompt and Claude response only
  • session or --session: report usage for the entire session (since last /clear or session start)

Parse the arguments from: $ARGUMENTS (accept both session and --session as the session flag)

Instructions

When this skill is invoked, scan the current conversation context and report what was used. Follow these detection rules exactly.

1. Detect Skills

Scan the conversation for:

  • <command-name> tags: extract the value (e.g., superpowers:brainstorming from <command-name>/superpowers:brainstorming</command-name> or <command-name>superpowers:brainstorming</command-name>)
  • Skill tool invocations in the conversation flow (where Claude called the Skill tool with a skill name)

Collect all unique skill names found.

2. Detect Hooks

Scan <system-reminder> tags for these patterns:

  • Text containing "hook additional context" (e.g., "SessionStart hook additional context", "UserPromptSubmit hook additional context")
  • Extract the hook name from the text before "hook additional context"

Collect all unique hook names found. Normalize to lowercase-kebab-case (e.g., "SessionStart" becomes "session-start", "UserPromptSubmit" becomes "user-prompt-submit").

3. Detect Rules

Scan the conversation for <system-reminder> blocks that contain # claudeMd sections. Within those sections, look for lines matching:

  • Contents of .../.claude/rules/<name>.md - extract <name> as the rule name
  • References to project-level CLAUDE.md files - report as "CLAUDE.md (project)" or similar

Collect all unique rule names found.

4. Detect Plugins

Scan the conversation for:

  • <system-reminder> blocks containing "# MCP Server Instructions" followed by ## <plugin-name> headings - extract the plugin name
  • <available-deferred-tools> blocks containing tool names prefixed with mcp__<plugin>__ - extract unique plugin names from the prefix
  • Skill names that contain a colon prefix (e.g., superpowers:brainstorming) - the part before the colon is the plugin name
  • Plugin-sourced skills listed in <system-reminder> skill availability blocks (e.g., "- superpowers:writing-plans: ...")

Changes

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.
