What is account-performance-diagnostics?

A troubleshooting guide for Google Ads accounts, covering drops in conversions, leads, or sales opportunities.

Checking campaign and ad-group metrics, comparing time periods, separating device or conversion types, and reviewing offline-conversion uploads.

It gives a defined way to compare performance data and investigate whether devices, conversion tracking, ad position, bids, or budgets caused the decline.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.00711
Opus 5.5	$0.00017	$0.00284
Sonnet 5.5	$0.00009	$0.00142
Haiku 4.5	$0.00004	$0.00071

Security

Grade A, and why

account-performance-diagnostics 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 2mo 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.

Account Performance Diagnostics Skill

This skill provides instructions on how to use the Google Ads MCP server to diagnose common account performance issues.

Workflows

1. Conversion and Conversion Value Loss

When conversions or conversion value suddenly decline, use the following steps to diagnose the issue.

Steps:

Discover Fields: Use get_resource_metadata with resource campaign or ad_group to ensure you have the correct field names.
Query Performance: Use search to retrieve performance data.
- Resource: campaign or ad_group
- Fields: Include campaign.name, metrics.conversions, metrics.conversion_value, metrics.cost_micros.
- Segments: To isolate the loss, include segments like segments.date, segments.device, segments.conversion_action.
- Conditions: Compare the period of decline with a previous period (e.g., segments.date >= 'YYYY-MM-DD').
Analyze: Check if the loss is limited to certain devices (e.g., mobile vs desktop) or specific conversion actions.
Check Uploads: If using offline conversions, consider checking offline_conversion_upload_conversion_action_summary for upload issues.

2. Opportunities Lost (Impression Share)

To identify lost opportunities due to ad rank, bids, or budgets, analyze impression share metrics.

Steps:

Query Impression Share: Use search to retrieve impression share metrics.
- Resource: campaign
- Fields: campaign.name, metrics.search_impression_share, metrics.search_rank_lost_impression_share, metrics.search_budget_lost_impression_share.
Analyze:
- High search_budget_lost_impression_share indicates opportunities lost due to limited budget.
- High search_rank_lost_impression_share indicates opportunities lost due to low ad rank (bid or quality issues).

3. Low Lead Flow Diagnostics

When a user asks "why is my lead flow low these past few days?", follow this systematic approach.

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.
