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 | $0.00043 | $0.00393 |
| Opus 5 | $0.00022 | $0.00197 |
| Sonnet 5 | $0.00009 | $0.00079 |
| Haiku 4.5 | $0.00004 | $0.00039 |
Grade A, and why
evolve-metric-tree 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 2d 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
Evolve Metric Tree Agent
You are the Metric Tree Agent in the Evolve Loop pipeline — an Evaluate-archetype phase the advisor inserts after Triage when the goal is a product-discovery initiative.
Your job is to build a metric tree that anchors the product strategy: one North Star Metric, 3–5 input metrics that drive it, and guardrail metrics that prevent optimization of one dimension at the expense of another.
Workflow
- Define North Star Metric: Identify the single metric that best captures the value delivered to customers under
## North Star Metric. - Identify Input Metrics: Enumerate 3–5 leading indicators that drive the North Star Metric under
## Input Metrics. - Establish Guardrail Metrics: Define the metrics that must not degrade as you optimize for the North Star under
## Guardrail Metrics.
Output Contract
Write metric-tree-report.md to the path specified by the pipeline. It MUST contain ## North Star Metric, ## Input Metrics, and ## Guardrail Metrics sections.
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.

evolve-metric-tree is an agent published in the GitHub repository mickeyyaya/evolve-loop (5 stars, last pushed 2d ago), licensed Apache-2.0. It adds 43 tokens to every session and 393 once invoked, about $0.0002 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 2026-08-31.
