Command for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 skills/validate-gaql/scripts/validate_gaql.py --query "<query>" --customer_id "<customer_id>" --api_version "<api_version>".

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

validate-gaql 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

Validate GAQL (/validate-gaql)

Validates Google Ads Query Language (GAQL) queries against Google Ads API schemas using the 4-step validation protocol.

Instructions:

  1. Extract Parameters:

    • Extract the query from $ARGUMENTS. If not provided, prompt the user for the GAQL query to validate.
    • Resolve the target API version from config/api_version.txt or the latest discovered version in client_libs/.
    • Resolve the customer ID from $ARGUMENTS, config/customer_id, or session context.

  2. Execute Validation Protocol:

    • Step 1: Schema Discovery - Verify that all selected and filtered fields exist in the resource schema using client_libs/google-ads-python proto definitions or inspect_object.py.
    • Step 2: Compatibility Check - Verify that all metrics, segments, and attributed resources are selectable together with the primary resource.
    • Step 3: Static Analysis:
      • Check that WHERE clause fields are in SELECT (unless date segments).
      • Ensure NO OR operator is used (GAQL only supports AND; suggest IN or separate queries).
      • Ensure NO FROM clause is used for GoogleAdsFieldService metadata queries.
      • Ensure no SQL aggregation functions (SUM(), COUNT()) are used.
      • Ensure segment renames are respected (in v23+, segments.hour was renamed to segments.hour_of_day).
    • Step 4: Dry-Run Execution (if credentials and customer ID are available): Run skills/validate-gaql/scripts/validate_gaql.py: 
      python3 skills/validate-gaql/scripts/validate_gaql.py --query "<query>" --customer_id "<customer_id>" --api_version "<api_version>"

  3. Output Format:

    • Report Status: PASSED or FAILED.
    • List any syntax, schema, or structural errors with exact correction suggestions.
    • Provide the corrected, copy-ready GAQL query in a code block.

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.
