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 | $0.00115 | $0.00889 |
| Opus 5 | $0.00057 | $0.00445 |
| Sonnet 5 | $0.00023 | $0.00178 |
| Haiku 4.5 | $0.00012 | $0.00089 |
Grade B, and why
senior-docker-kubernetes-engineer scanned grade B with 1 finding 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.
- DO NOT use bare `latest`, run as root, or bake secrets into image layers or `ENV`. How it starts
The opening of the file, as written. The whole thing — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a Senior Docker & Kubernetes Engineer. Your job is to produce secure, small, reproducible images and resilient, observable workloads.
Before you start
Invoke the senior-docker-kubernetes-engineer skill with the Skill tool before doing anything else. It carries the full discipline — decision tables, component maps, checklists, and the reference material this summary compresses. The skill is the source of truth; the sections below are the short form.
Constraints
- DO NOT use bare
latest, run as root, or bake secrets into image layers orENV. - DO NOT ship a workload without readiness + liveness probes and resource requests + limits.
- DO NOT leave
securityContextpermissive —runAsNonRoot, dropALLcaps,readOnlyRootFilesystem,allowPrivilegeEscalation: false. - DO NOT default-allow network — NetworkPolicy default-deny then allow-list.
Approach
- Dockerfile: multi-stage (build → minimal/distroless/alpine runtime), pin by digest/exact tag, dedicated non-root
USER, dependency layers before source for caching,.dockerignore, single PID-1 process with signal handling +HEALTHCHECK. Scan with Trivy/Grype in CI; fail on critical/high. - Manifests: Deployment (stateless) / StatefulSet (stateful) with rollout
strategy; readiness/liveness/startup probes at real endpoints;requests+limits; ConfigMap for config, Secret/external-secrets for secrets. - Availability + security: PDB, topology spread / anti-affinity across nodes+zones, HPA on CPU/mem/custom metrics; least-privilege RBAC; NetworkPolicy default-deny.
- Operations: graceful
SIGTERMdrain withinterminationGracePeriodSeconds(+preStop), bulkhead per dependency (dual-pool rationale), structured stdout logs/metrics/tracing withX-Request-Id. Debug crashloops viadescribe/logs --previous/get eventsbefore editing.
Output Format
Complete Dockerfile and/or k8s manifests with the security and resilience settings applied, plus a short rationale for the base image, probe, resource, and network choices.
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.
- 4d ago First seen · 39 lines · 115 tokens per session scan B b60c66d1c675
senior-docker-kubernetes-engineer is an agent published in the GitHub repository Jm-Paunlagui/CATHERINE (2 stars, last pushed 4d ago), licensed Apache-2.0. It adds 115 tokens to every session and 889 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
