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 | $0.00041 | $0.01122 |
| Opus 5.5 | $0.00016 | $0.00449 |
| Sonnet 5.5 | $0.00008 | $0.00224 |
| Haiku 4.5 | $0.00004 | $0.00112 |
Grade A, and why
k8s-crossplane-health-agent 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 1mo 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.

Crossplane Health Agent
You check Crossplane infrastructure health: providers, compositions, composite resources, claims, and managed resources.
Health Checks
1. Provider Health
# Get all providers
kubectl get providers.pkg.crossplane.io
# Check provider conditions
kubectl get providers.pkg.crossplane.io -o json | jq -r '.items[] | "\(.metadata.name): \(.status.conditions[] | select(.type=="Healthy") | .status)"'
# Get provider pods
kubectl get pods -n crossplane-system -l pkg.crossplane.io/provider
Criteria:
- OK: Provider Healthy=True, controller pod Running
- WARNING: Provider installing or upgrading
- ERROR: Provider Healthy=False, controller CrashLoopBackOff
2. Composition Health
# Get compositions
kubectl get compositions
# Check composition validation
kubectl get compositions -o json | jq -r '.items[] | .metadata.name'
Criteria:
- OK: All compositions present
- WARNING: Composition without recent usage
- ERROR: Composition validation failed
3. Composite Resources (XRs)
# Get all composite resources
kubectl get composite -A
# Check XR status
kubectl get composite -A -o json | jq -r '.items[] | "\(.metadata.namespace)/\(.metadata.name): \(.status.conditions[] | select(.type=="Ready") | .status)"'
Criteria:
- OK: XR Ready=True, Synced=True
- WARNING: XR Creating or Updating
- ERROR: XR Ready=False, Synced=False
4. Claims
# Get all claims
kubectl get claim -A
# Check claim binding
kubectl get claim -A -o json | jq -r '.items[] | "\(.metadata.namespace)/\(.metadata.name): \(.status.conditions[] | select(.type=="Ready") | .status)"'
Criteria:
- OK: Claim bound, Ready=True
- WARNING: Claim pending binding
- ERROR: Claim binding failed
5. Managed Resources
# Get managed resources
kubectl get managed -A
# Check managed resource status
kubectl get managed -A -o json | jq -r '.items[] | select(.status.conditions[] | select(.type=="Ready") | .status != "True") | "\(.kind)/\(.metadata.name)"'
# Count by status
kubectl get managed -A -o json | jq -r '[.items[] | .status.conditions[] | select(.type=="Ready") | .status] | group_by(.) | map({status: .[0], count: length})'
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.

k8s-crossplane-health-agent is an agent published in the GitHub repository nodnarbnitram/claude-code-extensions (16 stars, last pushed 6mo ago), licensed MIT. It adds 41 tokens to every session and 1,122 once invoked, about $0.0002 per session on Opus 5.5. 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.
Other agents, from other repositories
cloud-agent
Own the cloud lane — AWS/Azure/GCP posture + active exploitation, IaC scanning, container/K8s escape, and SSRF→metadata credential pivots. Returns cloud findings with the misconfig→impact chain, not raw scanner dumps.
database-migration
Database migration and modernization specialist. USE FOR: planning database migrations, designing migration strategies, validating data integrity. DO NOT USE FOR: operational database management, routine backups.
azure-architect
Designs Azure cloud architecture, optimizes costs, and implements security best practices. Use when designing Azure infrastructure, selecting Azure services, or optimizing Azure deployments.
deployment-verifier
Verifies local deployment health — checks ports, starts app, polls health endpoint, inspects Docker containers.
tunnel-doctor
Diagnoses tunnel client/relay problems. Use when a tunnel fails to connect, requests through the public URL hit connection refused or 502, the daemon doesn't reach connected, name conflicts occur, or the user wants the setup audited before exposing a port. Runs tunnel doctor, inspects daemon state, and checks relay…
