warden-power

warden-power is a command for Claude Code from vukkt/token-warden. It costs 53 tokens per session (394 once invoked), scanned A, original, MIT.

A read-only command that estimates how many benchmark runs are needed to detect a target token saving. It uses recorded variation between repeated runs and reports the smallest saving detectable at different run counts and confidence levels.

In plain words
What is it for?
Use it to calculate detectable savings, required runs per side, achieved power for a chosen run count, or the effect of changing the token-cost threshold.
Why use it?
It helps decide whether a benchmark has enough runs to produce a meaningful result before spending tokens on it.

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

warden-power 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 8d 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

Run the token-warden power command:

cd "${CLAUDE_SKILL_DIR}/.." && npx tsx src/power.ts $ARGUMENTS

Per agent it reports, from the recorded golden-replicate variance:

  • A table of runs-per-side (2, 3, 5, 8, 12) against the standard error and the minimum detectable saving at 80% and 90% power — the smallest true saving the 2x-rent + z-SE gate would actually promote at that budget.
  • With --target-saving N: the required runs per side to detect that saving at 80% and 90% power. A target at or below the 2x-rent bar is flagged as undetectable at any run count — the gate itself rejects it.
  • With --runs N: the MDS at exactly that n, plus (with a target) the achieved power percentage.
  • --rent N overrides the default rent (median context cost of the agent's active rules, 25 when none are deployed).

The estimate is conservative: it assumes uniform run allocation, and the selector's Neyman variance-proportional top-up only tightens the SE. Zero tokens, read-only. Relay the command output to the user.

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.

warden-power is a command published in the GitHub repository vukkt/token-warden (13 stars, last pushed today), licensed MIT. It adds 53 tokens to every session and 394 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
