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 | $0.00024 | $0.00155 |
| Opus 5 | $0.00012 | $0.00077 |
| Sonnet 5 | $0.00005 | $0.00031 |
| Haiku 4.5 | $0.00002 | $0.00015 |
Grade A, and why
wrdn-package-boundaries 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
Workspace packages should import each other through package exports, not relative paths.
Fix Shape
- Replace cross-package relative imports with the target package name.
- If the needed module is not exported, add the smallest package export that matches the package's public surface.
- Keep relative imports only within the same package root.
- Do not reach into another package's private source tree from an app or package.
Good
import { createExecutor } from "@executor-js/sdk";
Bad
import { createExecutor } from "../../../core/sdk/src";
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.

wrdn-package-boundaries is a skill published in the GitHub repository UsefulSoftwareCo/executor (3,494 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 155 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 2026-08-30.
