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 | $0.00019 | $0.00357 |
| Opus 5 | $0.00010 | $0.00179 |
| Sonnet 5 | $0.00004 | $0.00071 |
| Haiku 4.5 | $0.00002 | $0.00036 |
Grade A, and why
monitor-retention 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 8d 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
Command: monitor-retention
Inputs
- window – analysis window (month, quarter, rolling-90d).
- grouping – comma-separated dimensions (plan, persona, region, product, acquisition-channel).
- include-expansion – true/false to show upsell impact alongside churn.
- signals – optional list of metrics to emphasize (usage, support, sentiment, billing).
- format – dashboard | deck | brief.
Workflow
- Data Refresh – query billing, product telemetry, support, survey, and pipeline sources.
- Cohort Calculations – compute retention, churn, expansion, and health indexes per grouping.
- Signal Detection – surface top risk/improvement cohorts with quantified impact.
- Play Recommendations – map cohorts to lifecycle or CS save plays with owners.
- Packaging – produce dashboards/decks plus action trackers for leadership reviews.
Outputs
- Retention dashboard with drillable cohorts.
- Signal brief highlighting risks/opportunities + recommended plays.
- Action tracker with owners, due dates, and success metrics.

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.
