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 | $0.00015 | $0.09328 |
| Opus 5 | $0.00008 | $0.04664 |
| Sonnet 5 | $0.00003 | $0.01866 |
| Haiku 4.5 | $0.00002 | $0.00933 |
Grade D, and why
loom-crossplane scanned grade D with 3 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 4d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Crossplane Infrastructure Management
Crossplane extends Kubernetes to manage cloud infrastructure using declarative APIs. It enables platform teams to build internal cloud platforms with self-service capabilities.
Architecture Overview
Core Components
- Providers: Kubernetes controllers that provision infrastructure in external systems (AWS, GCP, Azure, etc.)
- Managed Resources (MRs): Custom resources representing external infrastructure (S3 buckets, RDS instances, etc.)
- Composite Resources (XRs): Higher-level abstractions composed of multiple managed resources
- Composite Resource Definitions (XRDs): Schemas defining composite resource types
- Compositions: Templates that map XRs to managed resources with transformation logic
- Claims: Namespace-scoped resources that provision composite resources for application teams
- Composition Functions: Extension points for complex transformation logic
Resource Hierarchy
Claim (namespace-scoped) -> Composite Resource (cluster-scoped) -> Managed Resources -> Cloud Infrastructure
Installation and Setup
Install Crossplane
# Add Crossplane Helm repository
helm repo add crossplane-stable https://charts.crossplane.io/stable
helm repo update
# Install Crossplane
# Composition functions are enabled by default since v1.14 — no feature-gate flag needed.
helm install crossplane \
crossplane-stable/crossplane \
--namespace crossplane-system \
--create-namespace \
--wait
# Verify installation
kubectl get pods -n crossplane-system
Install Crossplane CLI
# Install CLI for local development
curl -sL https://raw.githubusercontent.com/crossplane/crossplane/master/install.sh | sh
sudo mv crossplane /usr/local/bin/
# Verify CLI
crossplane --version
Provider Configuration
AWS Provider
v2 note:
ControllerConfig(pkg.crossplane.io/v1alpha1) was deprecated in v1.11 and removed in Crossplane v2. Configure provider runtime withDeploymentRuntimeConfig(pkg.crossplane.io/v1beta1, beta-enabled by default since v1.14) referenced viaruntimeConfigRef. Migrate any existing config withcrossplane beta convert deployment-runtime controller-config.yaml -o deployment-runtime-config.yamlbefore upgrading.
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.

loom-crossplane is a skill published in the GitHub repository cosmix/loom (54 stars, last pushed yesterday), licensed MIT. It adds 15 tokens to every session and 9,328 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
