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 | $0.00013 | $0.00303 |
| Opus 5 | $0.00006 | $0.00151 |
| Sonnet 5 | $0.00003 | $0.00061 |
| Haiku 4.5 | $0.00001 | $0.00030 |
Grade A, and why
bundle-analyze 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 6d 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
Bundle Analysis
- Check build tool:
cat package.json | grep -E '"build"|vite|webpack|rollup|esbuild|next'
- Generate bundle stats:
# Next.js
npx next build --analyze 2>/dev/null
# Vite
npx vite-bundle-visualizer 2>/dev/null
# Generic build size
bun run build 2>&1 | grep -E "\.js|\.css|kB|MB"
- Identify heavy dependencies:
cat package.json | grep -E '"dependencies"' -A 50
# Check bundle phobia for top suspects
-
Find optimization opportunities:
- Libraries with lighter alternatives (moment.js → date-fns, lodash → native)
- Packages imported entirely but only a few functions used
- Client-side code that could be server-side
- Missing dynamic imports for routes/heavy components
-

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.

bundle-analyze is a skill published in the GitHub repository berkcangumusisik/claude-code-practices (10 stars, last pushed 4mo ago), licensed MIT. It adds 13 tokens to every session and 303 once invoked, about $0.0001 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 2026-08-31.
