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

context-budget 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 5d 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.

What it actually says

Context Budget Optimizer

Analyze your Claude Code setup's context window consumption and produce actionable recommendations to reduce token overhead.

Usage

/context-budget [--verbose]
  • Default: summary with top recommendations
  • --verbose: full breakdown per component

$ARGUMENTS

What to Do

Run the context-budget skill (skills/context-budget/SKILL.md) with the following inputs:

  1. Pass --verbose flag if present in $ARGUMENTS
  2. Assume a 200K context window (Claude Sonnet default) unless the user specifies otherwise
  3. Follow the skill's four phases: Inventory → Classify → Detect Issues → Report
  4. Output the formatted Context Budget Report to the user

The skill handles all scanning logic, token estimation, issue detection, and report formatting.

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.
