inspect-object

A command that inspects the definitions of Google Ads API objects, messages, and enums. It shows their fields, data types, selectable or filterable fields, nested structures, and enum choices.

In plain words
What is it for?
Use it to inspect resources such as campaigns, ads, or bidding strategies, or to look up the allowed values of an enum.
Why use it?
It helps when you need to know exactly what data an API object contains or how a field can be queried. This reduces guesswork when writing queries and code.

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

inspect-object 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 2d 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

Inspect Object (/inspect-object)

Dynamically inspects the fields, data types, nested messages, and Enum values of any Google Ads API object using client_libs/google-ads-python proto definitions.

Instructions:

  1. Extract Parameters:

    • Extract the object name from $ARGUMENTS (e.g. Campaign, AdGroupCriterion, CampaignStatusEnum, AdGroupAd, BiddingStrategy).
    • If not provided, prompt the user for the object, message, or Enum name to inspect.
    • Resolve API version from config/api_version.txt or default to the latest discovered version.
  2. Execute Inspection:

    • Run the inspection script:
      python3 skills/inspect-object/scripts/inspect_object.py --name "$ARGUMENTS" --api_version "<api_version>"
      
    • If the script is unavailable in the environment, inspect the proto files directly in client_libs/google-ads-python/google/ads/googleads/<api_version>/.
  3. Output Format:

    • Object Type: Identify whether the symbol is a Resource, Message, or Enum.
    • Selectable / Filterable Fields: List core fields with data types and descriptions.
    • Enum Values: For Enum types, list all possible values and their meanings.
    • Nested Protobuf Messages: Show the structure of sub-messages.

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.
