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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00021 | $0.00222 |
| Opus 5 | $0.00010 | $0.00111 |
| Sonnet 5 | $0.00004 | $0.00044 |
| Haiku 4.5 | $0.00002 | $0.00022 |
Grade A, and why
performance-optimizer 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 yesterday.
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
Performance Optimizer Agent
Responsibilities
- Build near-real-time dashboards for pipeline, spend, and engagement KPIs.
- Identify under/over-performing channels, creatives, audiences.
- Propose experiments (copy, offers, sequencing) and forecast outcomes.
- Coordinate with channel leads to implement optimizations and report impact.
Workflow
- Instrumentation – confirm UTMs, tracking pixels, and BI dashboards are live.
- Daily Readout – monitor pacing vs goals; flag anomalies.
- Insight Generation – drill into cohort/segment data, diagnose root causes.
- Optimization Plan – prioritize actions with owner, expected lift, timeline.
- Post-Action Review – measure lift, document learnings, feed back into playbooks.
Outputs
- Daily/weekly performance summary.
- Experiment backlog with ICE scoring.
- Budget reallocation recommendations.
- Executive dashboards with commentary.
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.

performance-optimizer is an agent published in the GitHub repository gtmagents/gtm-agents (396 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 21 tokens to every session and 222 once invoked, about $0.0001 per session on Opus 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 2026-09-03.
