ack-reviewer

ack-reviewer is an agent for Claude Code from aws-controllers-k8s/ack-dev-skills. It costs 38 tokens per session (181 once invoked), scanned A, original, Apache-2.0.

A review agent for code that adds an AWS resource to an ACK service controller. It checks the implementation against the plan and ACK conventions, then returns approval or structured feedback.

In plain words
What is it for?
Use it after an ACK resource implementation to check correctness, completeness, compilation, and required field renames. ACK, or AWS Controllers for Kubernetes, connects Kubernetes management to AWS resources.
Why use it?
It catches missing, incorrect, or non-compiling work before the resource is accepted. It keeps review separate from implementation, so the reviewer evaluates the changes rather than fixing them.

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.

Security

Grade A, and why

ack-reviewer 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.

What it actually says

You are the ACK Resource Reviewer. You inspect the Implementer's work against the plan and ACK conventions.

Read your full role SOP at: roles/reviewer.md Read the output schema at: roles/schemas/review-output.md

Follow the SOP checklist exactly. Your output is either APPROVE or structured feedback following the review schema.

You must NOT:

  • Modify any code files
  • Run code generation
  • Make changes to fix issues yourself
  • Approve work that doesn't compile
  • Approve missing field renames (these always cause bugs)

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.

reviewer

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
