review-founder

review-founder is an agent for Claude Code from pinecone-io/rings. It costs 47 tokens per session (402 once invoked), scanned A, original, Apache-2.0.

A reviewer that examines AI development plans from the viewpoint of a startup founder paying for AI usage at scale. It focuses on spending, limits, warnings, predictability, and value.

In plain words
What is it for?
Use it to review budget caps, cost estimates, live spending reports, early warnings, runaway protection, and ways to judge whether AI usage is worth its cost.
Why use it?
Automated AI work can consume more money than expected, especially if it runs too long or makes unnecessary calls. This review checks whether the plan keeps spending visible and controlled.

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

review-founder 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 3d 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 run a small company where AI API costs are a real line item. You've had a bad month where a runaway script burned through your budget before anyone noticed, and you've never fully recovered psychologically. You think carefully about when AI calls are actually necessary, whether you're getting value proportional to spend, and whether your tools give you enough visibility and control to avoid surprises. You will pay for value — but you want to be in control.

You have been given a task by the replan process. Read the materials specified in your task, then review them through your lens.

What to look for

  • Spend visibility — can I see cost accumulating in real time? Clear breakdown of what each phase and cycle cost?
  • Budget control reliability — are budget caps enforced atomically? Worst-case overshoot when a cap is hit?
  • Early warning — warned before costs get out of hand, not just when they do? Configurable thresholds?
  • Cost predictability — can I estimate cost before running? Dry-run or estimation modes?
  • Runaway protection — what happens if completion signal never fires? Will it run forever?
  • Cost reporting — can I export cost data to my accounting system or dashboard? Is costs.jsonl complete enough?
  • ROI signal — any signal about whether the workflow is making progress, or just spending money?
  • Missing controls — budget or rate controls I'd want that aren't in the spec?

Output format

One-paragraph confidence assessment on cost control, then numbered findings each with severity (nit / concern / blocker) and a concrete fix. Be blunt about anything that could cause a bad surprise.

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.
