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 | $0.00590 |
| Opus 5.5 | $0.00011 | $0.00236 |
| Sonnet 5.5 | $0.00005 | $0.00118 |
| Haiku 4.5 | $0.00003 | $0.00059 |
Grade A, and why
skill-099-membership-duration-optimization 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 099: Membership Duration Optimization
Purpose
Optimize audience membership durations aligned to the business's buying cycle. Shorter windows capture urgency; longer windows re-engage users for high-consideration purchases.
Data Requirements
Data Source: Standard
Standard Data:
data/account/campaigns/*/audience_targeting.md- Audience configurationsdata/account/campaigns/*/*/audience_targeting.md- Ad group audiences
Reference GAQL:
SELECT
user_list.name,
user_list.membership_life_span,
user_list.size_for_display,
user_list.size_for_search
FROM user_list
WHERE user_list.membership_status = 'OPEN'
Use /google-ads:get-custom for conversion lag analysis:
SELECT
segments.conversion_lag_bucket,
metrics.conversions,
metrics.conversions_value
FROM campaign
WHERE segments.date BETWEEN '{start_date}' AND '{end_date}'
AND campaign.advertising_channel_type = 'DISPLAY'
Analysis Steps
- Determine Business Buying Cycle: Quick (7-30 days), Medium (30-90 days), Long (90-365 days)
- Review Current Durations: Extract membership durations from audience configurations
- Map Durations to Funnel Stage: High-intent = shorter, low-intent = longer
- Identify Mismatches: Cart abandoners >30 days, B2B audiences <60 days
Thresholds
| Condition | Severity |
|---|---|
| Cart abandoner duration >30 days | Warning |
| B2B audiences <60 days | Warning |
| All durations identical (no optimization) | Info |
| Exclusion list shorter than buying cycle | Warning |
| High-intent segment >90 days | Warning |
Output
Short (default):
## Membership Duration Audit
**Account:** [name] | **Business Type:** [type] | **Est. Buying Cycle:** [X days] | **Issues:** [count]
### Warnings
- **Cart abandoners at 60 days** - Reduce to 7-14 days for urgency
- **All audiences at 30 days** - No duration optimization applied
### Recommendations
1. Set cart abandoners to 7-14 days
2. Set product viewers to 30-60 days
3. Extend purchaser exclusion to [X days] to match buying cycle
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.

skill-099-membership-duration-optimization is a skill published in the GitHub repository TrueClicks/claude-plugins (2 stars, last pushed 22d ago), licensed MIT. It adds 27 tokens to every session and 590 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-08.
