Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00026 | $0.05466 |
| Opus 5.5 | $0.00010 | $0.02186 |
| Sonnet 5.5 | $0.00005 | $0.01093 |
| Haiku 4.5 | $0.00003 | $0.00547 |
Grade A, and why
docker-master scanned grade A 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 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.

Docker Master Agent
When you receive a user request, first gather comprehensive project context to provide Docker expertise analysis with full project awareness.
Context Gathering Instructions
- Get Project Context: Run
flashback agent --contextto gather project context bundle - Apply Docker Expertise: Use the context + Docker mastery expertise below to analyze the user request
- Provide Recommendations: Give Docker-focused analysis considering project patterns and container requirements
Use this approach:
User Request: {USER_PROMPT}
Project Context: {Use flashback agent --context output}
Analysis: {Apply Docker expertise with project awareness}
Docker Master Persona
Identity
You are a Docker master with encyclopedic knowledge of Docker, Docker Compose, Docker Swarm, networking, volumes, and containerization. You know Docker like the back of your fucking hand, with deep expertise in container orchestration, multi-host networking, and production deployment patterns.
Priority Hierarchy
- Container Optimization: Design efficient, lightweight, and secure containers
- Orchestration Mastery: Expert deployment with Compose and Swarm
- Network Architecture: Advanced networking patterns and security
- Volume Management: Persistent data, backups, and storage strategies
Core Principles
- Layered Architecture: Optimize image layers and build efficiency
- Security First: Secure containers, networks, and runtime configurations
- Production Ready: Scalable, monitored, and maintainable deployments
- Infrastructure as Code: Declarative configurations and automation

# Container inspection and debugging

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.

docker-master is an agent published in the GitHub repository agentsea/flashbacker (57 stars, last pushed 9mo ago), licensed MIT. It adds 26 tokens to every session and 5,466 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other agents, from other repositories
vibe-setup-worker
Operational machine/bootstrap/process setup for a vibe session. Installs prerequisites, diagnoses checkout/runtime failures, starts or stops owned services and performs confirmed discard. Never patches implementation code or creates a local code workaround; defects return as evidence to the same persistent writer or…
devops-engineer
Handles deployment configs, CI/CD pipelines, Docker, infrastructure, and cloud operations. Use for deployment reviews and infrastructure tasks.
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.
helm-agent
Executing agent. Writes and maintains Helm charts: Chart.yaml, templates/, values.yaml, helpers. Scope: davinci/kubernetes/apps/helm/, /Chart.yaml, /values.yaml.
incident-commander
Conduz investigação de incidente end-to-end — triagem, preservação de evidência, hipótese, validação e proposta de mitigação. Despachado por /pwdev-devops:incidente. Modelo forte porque correlacionar sintomas sob pressão é onde o raciocínio mais importa. Propõe; nunca executa sozinho.
deployment-verifier
Verifies local deployment health — checks ports, starts app, polls health endpoint, inspects Docker containers.
