ecs-recon SKILL.md skillA
ecs-recon from aws-samples/sample-apex-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add aws-samples/sample-apex-skills/ecs-recon@git:20261108.ad08020Pins git:20261108.ad08020 in mdr.lock. Pin the fingerprint instead.

ECS environment reconnaissance and discovery. Detects compute and capacity providers, task definitions, deployment configuration, auto scaling, networking, security posture, observability, and IaC/CI-CD tooling. Use when someone asks about their ECS environment, wants to describe a cluster, inspect a service, or document task definitions — even without naming the skill. Applies to Amazon ECS, not Amazon EKS (use eks-recon). Discovers current state only — does not score, audit, or design. Skip…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ECS Reconnaissance
Discover everything about an ECS environment. Run this skill to gather comprehensive context about clusters, services, and their tasks before making any decisions, changes, or recommendations. Standalone (`run-task`) and scheduled (EventBridge) tasks are not discovered — discovery enumerates workloads via `list-services`.
## When to Use This Skill
**Run this skill when the user:**
- Asks about their ECS environment ("what clusters do I have?", "describe my ECS setup")
- Wants to understand their service configuration ("what launch type?", "how is it deployed?")
- Plans to modify a service and needs current-state context first
- Asks to document or review their ECS resources
- Needs task definition details, scaling policies, or networking config
- Mentions an ECS cluster or service and seems to need context
**Also trigger this skill when:**
- Another workflow needs ECS environment information as input
- User mentions ECS and needs discovery before recommendations
- You need to understand the ECS setup before giving guidance
**Do NOT use this skill for:**
- **Cost scoring or efficiency analysis** — belongs to `ecs-cost-intelligence` (once available)

How to install
mdr add aws-samples/sample-apex-skills/ecs-recon@sha256:6ac45a567b589105The line at the top of this page pins the label git:20261108.ad08020, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
