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

keyword-planner 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 12d 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.

Keyword Planner

Overview

Use the local keyword-planner command to pull Google Keyword Planner ideas and search-volume metrics directly from the Google Ads API. The CLI calls Google's KeywordPlanIdeaService.GenerateKeywordIdeas, which is the API equivalent of the Keyword Planner flow in the Google Ads UI. Prefer this skill when the user asks for keyword volume, keyword ideas, demand validation, CPC/bid ranges, or a keyword list grounded in Keyword Planner rather than SERP estimates or memory.

Google does not charge a separate per-call fee for normal Google Ads API usage, but calls are governed by the developer token's access level and daily operation limits. The user still needs an eligible Google Ads account and approved API access.

Quick Start

Use JSON output by default so results can be filtered, sorted, and summarized reliably:

keyword-planner --keywords "seo tools" "keyword research" --output json

Use a URL seed when the user wants ideas from an existing page or competitor page:

keyword-planner --url "https://example.com/page" --output json

If sandbox policy requires approval for network/API access, request escalation before running the command. The command calls the Google Ads API.

Inputs

Collect or infer:

  • Seed keywords with --keywords, or one seed URL with --url.
  • Optional --customer-id if GOOGLE_ADS_CUSTOMER_ID is not already configured.
  • Optional --location-ids; default is 2840 for the United States.
  • Optional --language-id; default is 1000 for English.
  • Optional existing-content spreadsheet path for exclusion.

Ask for missing seeds if the user provides neither keywords nor a URL. Do not ask for credentials unless the command fails or the user has not configured a Google Ads customer ID.

Access and Credentials

There is no simple "Keyword Planner API key." The required access credential is a Google Ads API developer token, plus authentication credentials for the Google Ads account the CLI should query.

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.
