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

overcast-dork-recon 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.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

overcast-dork-recon

Use this skill to search a target domain's public exposure with Google dorking. The dork source (Serper.dev) passes your query verbatim to Google, so operators (site: filetype: inurl: intitle: ext: -term OR) are honored — unlike web (Tavily/Brave), which ignores them. Use the broad overcast skill and overcast/reference/verbs.md for exact flags.

⚠️ Authorized recon only. Dorking surfaces exposed and often sensitive material. Run it only against domains you are permitted to investigate. dork is never a default source — you bind it deliberately.

Setup

overcast doctor --sources --json                      # confirm SERPER_API_KEY is set
overcast case init --json
overcast case setup --target "<domain>" --yes --json
overcast source add 'dork:site:<domain>' --json       # register the dork source (any starter dork)

Dork template battery

Run each template as its own scan against the target domain <domain> — the ad-hoc --query overrides the bound ref, so one registered dork source serves the whole battery. --pull captures each result page as evidence.

# Exposed documents (reports, spreadsheets, slides, configs)
overcast scan --source dork --query 'site:<domain> filetype:pdf OR filetype:xls OR filetype:xlsx OR filetype:doc OR filetype:docx' --limit 20 --pull --json
# Open directory listings
overcast scan --source dork --query 'site:<domain> intitle:"index of"' --limit 20 --pull --json
# Login / admin portals
overcast scan --source dork --query 'site:<domain> inurl:login OR inurl:admin OR inurl:signin OR intitle:"admin"' --limit 20 --pull --json
# Config / secret / log files
overcast scan --source dork --query 'site:<domain> ext:env OR ext:sql OR ext:log OR ext:bak OR ext:ini OR ext:conf' --limit 20 --pull --json
# Error / debug pages that leak stack traces or paths
overcast scan --source dork --query 'site:<domain> "sql syntax near" OR "stack trace" OR "Warning: mysql" OR "Fatal error"' --limit 20 --pull --json
# Git / backup / archive exposure
overcast scan --source dork --query 'site:<domain> inurl:.git OR inurl:backup OR ext:zip OR ext:tar OR ext:gz' --limit 20 --pull --json
# Subdomain / host discovery (exclude the apex www)
overcast scan --source dork --query 'site:*.<domain> -www' --limit 20 --pull --json

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.
