What it does
Resilience Hub Failure Mode Assessment is an agent skill from aws/agent-toolkit-for-aws, published by the product's own GitHub organization. Runs and interprets AWS Resilience Hub v2 failure mode assessments. Covers starting assessments, understanding findings (severity, categories, recommendations), triaging by achievability, working with AI-generated service functions, and resolving findings. Applies when the user wants to run an assessment, review findings, or understand failure modes, or has a specific finding and asks how to resolve, remediate, or fix it. Does not apply to initial setup (use resilience-hub-getting-started) or FIS experiments.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/assessment-workflow.md`).
It sits in Development, covering Code review. It works with Amazon Web Services and Model Context Protocol. The repository describes itself as: Official, AWS-supported MCP servers, skills, and plugins to help AI agents build on AWS. The licence is Apache-2.0.
When your agent uses it
- Wants to run an assessment
- Review findings
- Understand failure modes
- Has a specific finding and asks how to resolve
Example prompts
- “/resilience-hub-failure-mode-assessment”
What it can do on your machine
Read from SKILL.md and the folder at commit 2cb0fa1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
aws
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
docs.aws.amazon.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Resilience Hub Failure Mode Assessment loads about 1k tokens when it runs, and up to ~4.3k if it reads all its reference files. Until then it costs about 138 tokens; SKILL.md has 413 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Failure Mode Assessment
Overview
Domain expertise for running Resilience Hub v2 failure mode assessments, interpreting findings, triaging by severity and achievability, and driving remediation.
The AWS MCP server is recommended for executing this skill's AWS API calls, but it is not required — all operations also work with the AWS CLI directly.
Guardrail — where this skill's own files live (MCP vs local install)
Before reading a reference file, determine how this skill was loaded:
- Loaded via the AWS MCP
retrieve_skilltool: the skill's reference files are not on the local filesystem. Fetch each one throughretrieve_skillwith thefileparameter (e.g.file="references/assessment-workflow.md") — do NOTfile_readthese paths locally or search the filesystem for them. - Installed locally (e.g.
.kiro/skills/resilience-hub-failure-mode-assessment/or~/.claude/skills/resilience-hub-failure-mode-assessment/): read reference files from the local skill directory using the relative paths shown here.
This applies only to the skill's own reference files; always read and write user or session data in the working directory, never through retrieve_skill.
Run and interpret assessments
To run assessments and triage findings, follow the procedure exactly. See references/assessment-workflow.md.
Troubleshooting
Assessment fails with INVALID_PERMISSIONS
The service's permission model (invokerRoleName / crossAccountRoles) doesn't have access to the resources. Verify the invoker role (and any cross-account roles) can describe resources in all configured regions.
Too many findings — where to start?
Prioritize by finding severity, highest first (HIGH, then MEDIUM, then LOW). For HIGH-severity
findings, check the service's achievability for the relevant policy component (from get-service
/ list-failure-mode-assessments): NOT_ACHIEVABLE means the architecture must change before
testing; ACHIEVABLE means validate the fix with an FIS experiment. MEDIUM findings: plan
remediation this sprint; LOW findings: track but don't block (see the priority matrix in
references/assessment-workflow.md Step 5).

AI-generated service functions are wrong
Update them: aws resiliencehubv2 update-service-function to rename or change criticality
(there is no service-function "type" parameter). Reassign resources by calling create-service-function-resources with the desired resource set (see references/assessment-workflow.md for the service-function operations).
Security Considerations
- Least privilege: the invoker role should be scoped to read-only discovery of only the resource types in the service's input sources; avoid granting access beyond what assessment needs.
- Encryption & access control: recommend that S3 buckets used for report output have server-side encryption (SSE-S3 or SSE-KMS) and block public access — assessment reports can contain sensitive architectural detail. If a bucket policy grants the Resilience Hub service principal write access, scope it with
aws:SourceArn/aws:SourceAccountcondition keys to prevent confused-deputy writes. - Further reading: see Security in AWS Resilience Hub and the AWS Well-Architected Security Pillar for securing assessment outputs and IAM configurations.
