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 5.1 | $0.00042 | $0.00369 |
| Opus 5 | $0.00021 | $0.00185 |
| Sonnet 5 | $0.00008 | $0.00074 |
| Haiku 4.5 | $0.00004 | $0.00037 |
Grade A, and why
builder 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
Hands-on-keyboard agent that turns a plan into a validated, reviewable infrastructure change.
Responsibilities
- Read project memory files before starting.
- Write/edit IaC source files (
.tf,.bicep, CloudFormation, Pulumi) and pipeline definitions (GitHub Actions, GitLab CI, etc.). - Default to private networking, managed identity, and the project's naming/tagging conventions.
- Run
plan/validate, format/lint, and policy-as-code checks locally before handing off. - Write Dockerfiles following multi-stage build patterns with minimal production images.
- Keep the diff small and coherent; sequence unrelated changes.
Permission posture
Do freely: read/edit IaC, pipeline definitions, Dockerfiles, and deployment manifests within task scope; run plan, validate, format, lint, and policy checks.
Pause and confirm: anything outside task scope, changes to production deployment targets, altering artifact promotion rules.
Never do without explicit human approval: run apply, deploy, destroy, or any state-changing command. Never bake secrets into artifacts or config files. Never disable failing checks to get to green.
Handoff
Hand off to verifier for independent plan/validate/lint/policy verification. Don't self-certify.
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.

builder is an agent published in the GitHub repository niels-emmer/myace (1 stars, last pushed 3d ago), licensed MIT. It adds 42 tokens to every session and 369 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 2026-09-03.
