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 | $0.00056 | $0.00443 |
| Opus 5.5 | $0.00022 | $0.00177 |
| Sonnet 5.5 | $0.00011 | $0.00089 |
| Haiku 4.5 | $0.00006 | $0.00044 |
Grade A, and why
lightpanda 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 1mo 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
Lightpanda
Fast headless browser (~107MB binary, Zig). No MCP — direct CLI calls only.
Binary: ~/.local/bin/lightpanda
Core Commands
Fetch a URL (dump HTML)
~/.local/bin/lightpanda fetch --dump https://example.com
Save to file (avoid flooding context)
~/.local/bin/lightpanda fetch --dump https://example.com > /tmp/page.html
With logging
~/.local/bin/lightpanda fetch --dump --log_level info https://example.com
Respect robots.txt
~/.local/bin/lightpanda fetch --dump --obey_robots https://example.com
CDP Server (for Playwright/Puppeteer integration)
~/.local/bin/lightpanda serve --host 127.0.0.1 --port 9222
Then connect Playwright via browserWSEndpoint: 'ws://127.0.0.1:9222'.
Usage Rules
- Always save to /tmp/ when fetching pages — never let raw HTML flood context
- Use
fetch --dumpfor read-only content extraction - Use
serveonly when interactive automation is needed (preferfetchotherwise) - Disable telemetry if needed:
LIGHTPANDA_DISABLE_TELEMETRY=true - Does NOT support screenshots — use Playwright for that
Comparison vs Playwright
| lightpanda | playwright (mcporter) | |
|---|---|---|
| Overhead | None (pure CLI) | MCP + mcporter |
| Use case | Read HTML content | Full browser automation |
| Speed | Instant | Slower startup |
| Screenshots | No | Yes |
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.

lightpanda is a skill published in the GitHub repository spideynolove/claude-dotfiles (2 stars, last pushed 5mo ago), licensed MIT. It adds 56 tokens to every session and 443 once invoked, about $0.0002 per session on Opus 5.5. 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.

Also use when the user mentions…
interactive-login
Log a CLI in with a browser/device-code flow (aws sso, gh, glab, gcloud, …) and save the result to the keychain so later commands can request it through execute.credentials.
