What is firehose-operation-review?

An operational review tool for Amazon Data Firehose, an AWS service that sends streaming data to storage or other destinations. It checks delivery streams against AWS reliability, security, performance, cost, and quota guidance using read-only service data.

Use it to audit Firehose streams, investigate delivery health or freshness problems, assess operational readiness, and review quotas and cost drivers.

It helps find delivery delays, failures, throttling, security gaps, and avoidable costs without reading delivered records or sending test data. The review produces evidence for human decisions rather than changing the streams.

Token cost

What it costs to keep this loaded

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	$0.00145	$0.05537
Opus 5.5	$0.00058	$0.02215
Sonnet 5.5	$0.00029	$0.01107
Haiku 4.5	$0.00015	$0.00554

Security

Grade A, and why

firehose-operation-review 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 8d 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.

Amazon Data Firehose Operational Review

Conduct a comprehensive operational review of Amazon Data Firehose (formerly Amazon Kinesis Data Firehose) delivery streams aligned with the AWS Well-Architected Framework and Amazon Data Firehose best practices.

This skill uses the Firehose, CloudWatch, and Service Quotas APIs only — all data is collected through native AWS control-plane APIs and CloudWatch metrics. It performs no data-plane record puts and reads no delivered record content.

When to Use

Activate this skill when the user asks to:

Review, audit, or assess Amazon Data Firehose delivery streams
Check Firehose best-practices compliance
Evaluate Firehose security, reliability, delivery health, performance, cost, or quotas
Perform a Firehose operational readiness review (ORR)
Investigate delivery lag (data freshness), delivery failures, throttling, or cost drivers

Review Checklist

Work through these steps in order — each depends on the outputs of the ones before it. Track progress against this checklist and do not skip a step unless its scope makes it inapplicable (e.g. a single-stream review skips the account rollup).

Step 1: Identify target scope (accounts, regions, streams, pillars, window)
Step 2: Discover Firehose resources and capture per-stream config
Step 3: Collect CloudWatch metrics (load the thresholds reference first)
Step 4: Analyze against best practices (load the checklist reference first)
Step 5: Generate the report (load the report template)
Step 6: Track findings over time (recurring reviews)

Step 1: Identify Target Scope

Ask the user which accounts and regions to review, and whether to focus on a specific delivery stream. Accept:

Specific account IDs and regions
A specific delivery stream name (or "all streams")
"all regions" for a given account
A specific pillar or set of checks (e.g. "just reliability and cost"). Map free-text pillar names to this canonical set (accept the listed aliases, case-insensitive): security; reliability (aliases: resiliency, availability, durability); performance (perf); service-quotas (quotas, limits); cost (cost-optimization, cost optimization, finops); operational-excellence (ops, opex, operations); sustainability (green, efficiency). If a requested term matches none of these, ask the user to pick from the canonical list rather than guessing; if the run is unattended, default to all pillars.

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.
