Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00027 | $0.00609 |
| Opus 5.5 | $0.00011 | $0.00244 |
| Sonnet 5.5 | $0.00005 | $0.00122 |
| Haiku 4.5 | $0.00003 | $0.00061 |
Grade A, and why
skill-149-promotional-extensions-countdown-customizers 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 21d 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.

Skill 149: Promotional Extensions and Countdown Customizers
Purpose
Audit promotion extensions and countdown customizers for upcoming events. Promotional extensions highlight offers directly in ads while countdown customizers create real-time urgency. Both significantly boost CTR and conversion rates during promotional periods.
Data Requirements
Data Source: Standard
Standard Data:
data/account/ext_promotion.md- Promotion extension settings and schedulesdata/account/campaigns/*/ad_groups/*/ads.md- Ad copy with countdown customizers
Reference GAQL:
SELECT
asset.name,
asset.type,
asset.promotion_asset.occasion,
asset.promotion_asset.discount_modifier,
asset.promotion_asset.percent_off,
asset.promotion_asset.money_amount_off.amount_micros,
asset.promotion_asset.start_date,
asset.promotion_asset.end_date
FROM asset
WHERE asset.type = 'PROMOTION'
Use /google-ads:get-custom if you need asset-level performance data or extended date ranges.
Analysis Steps
- Review promotion extensions: Check
ext_promotion.mdfor active, scheduled, and expired promotions - Verify promotion coverage: Ensure upcoming events have extensions with correct dates and discounts
- Audit countdown customizers: Search ad copy for
{COUNTDOWN(...)}syntax - Check countdown accuracy: Verify countdown dates are current and match actual promotion end dates
- Identify seasonal ad copy gaps: Look for missing holiday-specific messaging in headlines/descriptions
Thresholds
| Condition | Severity |
|---|---|
| Event within 7 days with no promotion extension | Critical |
| Active promotion extension with past end date | Critical |
| Countdown customizer with past date | Critical |
| Promotion discount doesn't match actual offer | Warning |
| No countdown customizers for limited-time event | Warning |
| Promotion extension not linked to relevant campaigns | Info |
Output
Short format (default):
## Promotional Extensions Audit
**Account:** [Name] | **Events (60d):** [X] | **Extension gaps:** [Y]
### Critical ([Count])
- **[Event]**: No promotion extension -> Create [discount type] for [dates]
- **[Extension]**: End date [past date] -> Remove or update
### Warnings ([Count])
- **[Event]**: No countdown in ads -> Add "{COUNTDOWN([date])}" to headlines
### Recommendations
1. [Specific extension to create with discount, dates, and campaigns]
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.
