Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00014 | $0.00330 |
| Opus 5 | $0.00007 | $0.00165 |
| Sonnet 5 | $0.00003 | $0.00066 |
| Haiku 4.5 | $0.00001 | $0.00033 |
Grade A, and why
hud-update-pricing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Update Pricing
Updates the third-party model pricing table by fetching the latest prices.
Steps
1. Read config and fetch URL
HUDP="$HOME/.claude/plugins/claude-hud-enhanced"
UPDATE_URL=$(node -e "const c=JSON.parse(require('fs').readFileSync('$HUDP/config.json','utf8'));console.log(c.modelPricing?.pricingUpdateUrl||'https://raw.githubusercontent.com/johnleeGitHub/claude-hud-enhanced/master/pricing.json')")
echo "Fetching from: $UPDATE_URL"
2. Fetch and save
node -e "
import('$HUDP/dist/update-pricing.js').then(async m=>{
const d=await m.fetchPricing('$UPDATE_URL');
if(!m.validatePricingResponse(d)){console.error('ERROR: invalid pricing');process.exit(1)}
m.writePricingFile('$HUDP/pricing.json',d);
const c=JSON.parse(require('fs').readFileSync('$HUDP/config.json','utf8'));
c.modelPricing=(c.modelPricing||{});c.modelPricing.pricingUpdatedAt=new Date().toISOString();
require('fs').writeFileSync('$HUDP/config.json',JSON.stringify(c,null,2)+'\n');
console.log('OK: '+d.entries.length+' entries updated')
}).catch(e=>{console.error(e.message);process.exit(1)})
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.
