ddgr

A skill for searching the web through the DuckDuckGo command-line search tool called ddgr. It can return search results in machine-readable JSON or plain text.

In plain words
What is it for?
Use it to search online with a query, limit the number of results, target a region, and obtain titles, URLs, and summaries.
Why use it?
It provides a repeatable terminal-based way to look up information, verify facts, and collect source links.

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

ddgr 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 yesterday.

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

Ddgr

Search the web from the terminal with ddgr.

ddgr --noprompt --noua --json --num 10 "query terms"

Search Web

Preferred command (machine-readable JSON):

ddgr --noprompt --noua --json --num 10 "query terms"

Search with region targeting:

ddgr --noprompt --noua --json --num 10 -r us-en "query terms"

Common options:

  • --json: Return JSON results for deterministic parsing
  • --num <N>: Maximum number of results
  • -r <region>: Region code such as us-en or gb-en
  • --noprompt: Non-interactive mode
  • --noua: Disable random user-agent behavior

Fallback

If --json is not supported by the installed ddgr version, use plain output:

ddgr --noprompt --noua --num 10 "query terms"

Summarize results with title, URL, and snippet for each entry.

Changes

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.

ddgr is a skill published in the GitHub repository adampoit/ai (2 stars, last pushed 7d ago), licensed MIT. It adds 37 tokens to every session and 281 once invoked, about $0.0002 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.
